2010 Acura ZDX
Previewed at the 2009 New York Auto Show as a prototype, the 2010 ZDX is entering the auto market as a main competitor for the BMW X6. It features dramatic styling, outstanding performance and the latest in advanced technology. Sales will begin this winter and the ZDX will be offered in three distinct trim levels: the base ZDX, ZDX with the Technology Package and the top of the line ZDX with the Advanced Package. However prices have yet to be officially announced and are expected to be reveled sometime in the near future.
Under the hood, Acura will use a 3.7 Liter V6 that will put out 300 HP and 270 lb-ft of torque and will be mated to an all new 6 speed automatic transmission.
Designed to merge the emotional appeal of a sports coupe and all-season, all-surface versatility, the all-new ZDX breaks new barriers for Acura and for the luxury market. Its "Passionate Getaway" design honors the driver and passenger first, while also providing an impeccably finished luggage storage area that bests that of most luxury sedans. The rear seat area, with its abbreviated doors and door handles creatively integrated into the C-pillar, accommodates three additional passengers as required for occasional trips. But overall, the ZDX targets its mission as a 2-passenger personal escape vehicle with unmistakable Acura style.
The ZDX will be offered with a host of creature comforts and technological innovations, like: the panoramic glass roof with retractable sunshade, hand crafted leather interior, HandsFreeLink Bluetooth connectivity for cellular telephones, a power lift tailgate as well as a high powered stereo system that will play everything from CDs and iPods to AM/FM/XM radio signals, all standard.
Press release after the jump.
The all-new provocative 2010 ZDX four-door sports coupe will arrive at Acura dealerships with dramatic styling, outstanding performance and the latest in advanced technology. The segment bending ZDX features stunning coupe-like styling with the added benefit of a commanding presence and flexible utility. Staying true to the prototype model that debuted at the 2009 New York Auto Show in April, the production ZDX will feature the key design highlights of a panoramic glass roof, hidden rear door handles and bold fender flares.
Along with head-turning styling, the ZDX will boast outstanding performance from its 3.7-liter V-6 engine mated to an all-new 6-speed automatic transmission. The 3.7-liter SOHC V-6 all-aluminum engine will generate 300 horsepower and 270 lb-ft of torque for immediate acceleration response, outstanding low- and mid-range torque and superior high-rpm power. The 6-speed automatic transmission with steering wheel mounted paddle shifters gives the ZDX excellent acceleration while also enhancing fuel economy. Standard on the ZDX is Acura’s exclusive Super Handling All-Wheel Drive™ (SH-AWD®) system. The SH-AWD® system expands the ZDX’s appeal by providing outstanding handling as well as superior all-season capability. Standard on the ZDX are 19-inch, 7-spoke alloy wheels; the largest standard wheel in the Acura lineup.
Inside, the ZDX exhibits the highest levels of refinement and sophistication. Every ZDX interior will feature a hand-stitched leather dash, panels and sculpted center console. The rich leather appointments give the ZDX a warm and inviting feeling while creating an intimate cockpit for the driver and passenger.
The ZDX’s flexible utility enables customers to have great utility coupled with sleek styling. The ZDX can seat up to five adults while maintaining a generous amount of cargo space behind the second row of seats. The cargo area can also be expanded to accommodate longer objects, such as golf bags, by removing side panels in the cargo-compartment sidewalls. As an added bonus, there is an integrated under-floor storage area.
When the ZDX goes on sale this winter, customers will have the choice of three distinct trim levels: ZDX, ZDX with Technology Package and the ultra premium, ZDX with Advance Package. Like all Acura models, the ZDX will come generously equipped from the start. The panoramic glass roof with moveable sunshades, hand-stitched leather interior, HandsFreeLink™ Bluetooth® connectivity, power tailgate, and a high powered audio system with CD player, AM/FM/XM radio and USB audio interface with iPod® integration are all standard features.
The ZDX with Technology Package adds several features including a Navigation System with Voice Recognition™, an Acura/ELS Surround® premium audio system and a new multi-view rear camera. The Advance Package boasts additional customer enhancing technologies like a blind spot information system, a Collision Mitigating Braking System™ (CMBS™), and Adaptive Cruise Control (ACC).
When the ZDX goes on-sale, it will bring a new level of prestige to the Acura lineup. The ZDX will be priced and positioned between the MDX luxury SUV and the RL luxury sedan. Pricing and additional details will be released at a later date.
"This is a vehicle for those well-tanned, Cialis-addled boomers you see frittering away their early retirements on winery tours, decorator consults, and elective surgeries. In other words, the kind of people a maitre d’ seats us far away from."(CarAndDriver)
In its ongoing relationship with its clients, the Acura Division noticed that some of them own both a sports coupe and an SUV-the former for its performance and highly personal driving character, and the latter for its utility and practicality for hauling personal gear as well as for going places where the road conditions are difficult. This basic premise-combining a personalized "coupe" driving experience with versatile functionality-drove the new 2010 Acura ZDX’s body and chassis designs. As such, the ZDX has a distinctive design flair unmistakable with any competitor, and the all-season (and even off-highway) wherewithal to go almost anywhere in comfort, safety and style.
An additional list of design elements earmarks the ZDX as top shelf. These include standard High Intensity Discharge (HID) headlights, plentiful use of high-strength steel, aluminum and magnesium in the vehicle, and convenience features like a power rear tailgate. An available Technology Package and Advance Package further enhance functionality and luxury.
EXTERIOR DESIGN GOALS
The primary exterior design goal for the ZDX was to create a distinctive, modern personal "sports coupe" body while providing adequate ground clearance and favorable approach and departure angles that allow off-highway use. In simple terms, the overall goal for ZDX was to combine two parts sports coupe with one part all-surface capability to create a one-of-a-kind performance sports coupe with outstanding versatility. The result is a highly emotional design that inspires and encourages drivers to pursue a passionate getaway of their own.
Conceived and developed entirely at the new Acura Design Studio in Torrance, California, some of the most unique styling elements of the ZDX include deep-draw body panels that create a muscular stance, strong character lines including bold wheel arches, cleverly concealed rear door handles, and the expansive panoramic glass roof.
Body In Motion
The strong character lines along the bodyside add an element of suspense to the ZDX design. The body appears to be in motion even when the ZDX is standing still, and there is a distinct element of tension communicated by the interaction between the different body surfaces. From above, the ZDX panoramic roof has a distinct "pulled" look, similar to the look of a slingshot just before release. This generates a sporty and aerodynamic silhouette unlike any other vehicle in the market.
Additional character elements include Acura’s distinctive grille shape, sharply flared front fenders, dramatically rising character lines sloping rearward along the sides and an artfully sloping rear deck. All in all, the ZDX body lends the appearance of being pulled taut over a muscular skeleton. Acura designers refer to this directionality, pulled and tension as "suspenseful emotion." Numerous separate-and yet intertwined-design elements go into the ZDX’s body design. The list includes "Keen Edge" side-panel character lines that attract the eye up and back across the bodyside, and a highly kinetic look that is simultaneously unique and refreshing.
Bright and Black Finishes
Adding emphasis and elegance to the ZDX body design is a continuous stainless-steel trim feature that completely encircles each side window, along with a gloss-black finish on the window pillars.
DEEP DRAW SIDE PANELS
Integrating the inventive "sports coupe" body design onto a taller, wide-track chassis required total commitment from the manufacturing team as well as the design engineers. This is because rendering the rear bodysides, broad fenders and more vertical upper bodysides from a single steel panel required a particularly "deep draw" process that had never been mass-produced before. Adding to the challenge was the tight 8mm radius on the character line running along the bodyside-a much tighter radius than found on other Acura vehicles.
Because maintaining the deep-draw panels was an essential part of the body design, the manufacturing team was tasked with finding a way to produce them. Although the goal was to use a single metal panel to avoid the unsightly seams that can result when multiple panels are welded together, they left no avenue unexplored-from hand fabrication to stretching the limits of existing stamping technology. Initially told by the stamping experts that the body panel was impossible to make, the designers turned to hydroforming, but there were no presses available in an appropriate size for such stamping technology. The manufacturing team next agreed to try building a panel in two pieces, seaming it in the taillight area and under the rear door cutline, but eventually rejected that concept too.
Eventually the original stamping team, working in secrecy, found a way to make the part in one piece with the help of a low-friction phosphate coating between the die and the steel panel, which improves its formability. Although creating the one-piece deep-draw side panel took a year and a half of development work, the finished component dramatically adds to the ZDX’s provocative appearance and enhances the precision of the metal craftwork.
Befitting its "sports coupe" design, the 2010 ZDX is also longer, lower/wider and features a significantly wider track than its primary market competitors. As a result, in stature as well as design, the ZDX offers an especially dramatic appearance and driving character.
Developed by a team of Acura engineers based in Ohio, the 2010 ZDX utilizes an Advanced Compatibility Engineering™ (ACE™) body structure that more evenly distributes collision forces through the entire vehicle structure during a frontal accident while simultaneously helping to retain the integrity of the passenger compartment. Attaining a high level of dynamic body rigidity is essential for precise handling, ride quality and quietness inside the cabin-something that is especially true for the ZDX with its large panoramic glass roof feature.
By researching the body’s dynamic response to chassis loads during everyday driving, ZDX engineers considered the unit body’s "dynamic stiffness" as an entire system, not just as an individual component. Thus body rigidity is not an end to itself-rather it is an enabler for enhanced vehicle dynamics, ride comfort and driving quietness.
In addition to the rigidity of the panoramic roof opening being critical to ride, handling and safety during a potential rollover, instrumented testing revealed that the "tailgate ring" (the structure surrounding the tailgate) is extremely important for handling, stability and ride. In the 2010 ZDX this area is extremely rigid, providing the rear suspension with a solid mounting structure that nets improved handling precision.
The passenger compartment and other key areas of the ZDX body structure are formed from high-strength steel, with 48-percent of unit body constructed of the advanced material. High-strength steel contributes to rigidity, excellent crashworthiness and lighter weight, with different grades of the steel specified for use in different parts of the vehicle. Some areas using high-strength steel include the A- and B-pillars, floor sills, roof frame, cross braces, and floor cross members.
Lightweight materials including aluminum are used to further reduce vehicle mass, which helps improve performance while lowering fuel consumption and emissions. Aluminum is used for certain ZDX components such as the hood and instrument panel support, where light weight is required but the strength of steel is not imperative. In total, about 5-percent of the 2010 ZDX body components are aluminum.
Compared to steel, the weight savings of using aluminum for the ZDX hood is about 15 pounds. Aside from using a unique metal conditioner and phosphate dip prior to painting, there are no unique production challenges in using aluminum body panels-and no ownership compromises either. A single, large-volume gas strut supports the hood when open.
The aluminum instrument panel support assembly saves approximately 14 pounds compared to a traditional steel unit. This support, which connects the A-pillars to the front floor cross member, is a structural element consisting of special extrusions and stamped sheet aluminum.
The 2010 Acura ZDX spent considerable time in the wind tunnel to test and develop its aerodynamic properties. The attention to detail in aero efficiency included the development of stylized lower bodyside sills that help keep air from moving underneath the vehicle and causing turbulence. Lift balance and the coefficient of lift were also addressed to keep the ZDX stable at high speeds.
Numerous aerodynamic details direct and smooth the airflow underneath the vehicle, contributing to better engine cooling, greater fuel efficiency, lower emissions and reduced interior noise. Some of these include:
- An air dam beneath the front bumper directs airflow up and rearward to the radiator
- Small strakes ahead of the front and rear wheels direct air around the tires
- A pair of strakes in the middle of the underbody area help keep air separated from the bottom of the vehicle at higher speeds
- A mid-floor undercover helps keep air from tumbling past the fuel tank and rear differential
Special acoustic windshield glass is used on the ZDX to help reduce noise entering the cabin. Tuned specifically to attenuate wind-noise frequencies, the windshield glass uses two layers of 2mm safety glass with an inside layer of a transparent and elastic acoustic membrane for a total thickness of 4.7mm. The acoustic glass windshield helps place the ZDX at the top of its class in wind-noise performance.
The windshield incorporates UV light absorbing technology just like the 4mm thick panoramic roof glass, 5mm thick front side and 3.5mm rear side glass along with the 3.1mm thick rear tailgate glass.
The ZDX’s windshield benefits from a new defroster system that is nearly invisible from the driver’s perspective, yet delivers much improved area coverage and quicker defrost time as compared to previous Acura models.
The 2010 ZDX offers 271 degrees of outward visibility-more than the BMW X6-a significant accomplishment considering the dramatic "sports coupe" upper body design with its aggressively sloping rear cabin.
Engineers attacked noise from virtually every source inside and outside the ZDX, with the primary goal of reducing noise at its source. One creative noise-reduction technique is the use of composite seals in the exterior door panels. These "weather strip" seals actually serve two purposes-to reduce the transmission of noise through the doors, and to shield the interior components from dirt and water while driving through heavy rain or puddles. The door insulators provide a substantial reduction in objectionable sound-up to five decibels on some roads.
The ZDX’s front door handles are sized for comfort as well as ease of use, regardless whether the user is bare handed or wearing winter gloves. There are three door checker positions-the detent mechanism that holds the door partially open-instead of the usual two, providing a convenient "in between" position in tight parking situations. The door openings are finished with an attractive composite garnish that hides the doorsill when the door is open.
The rear door handles are mounted vertically on the trailing edges of the doors, and blend into the black garnish above the beltline of the vehicle. The design emphasizes the "sports coupe" body silhouette, making the ZDX appear like a 2-door vehicle while still providing the convenience and utility of four doors. Attention to detail in the sealing of the doors and tailgate also heightens the performance of the ZDX’s overall noise level. Designers even focused attention on the smoothness of the inside of the door openings, ensuring that no spot welds or other inconsistencies mar the smooth finish.
Ingress and Egress
Focusing on its "Passionate Getaway" mission, the ZDX design purposefully emphasizes the front doors. However designers also worked diligently to make the more abbreviated rear doors useful as well. The ZDX rear doors open an impressive 78 degrees to allow passengers a wide usable area between the door and bodyside.
The Acura ZDX uses Bi-Functional High-Intensity Discharge low and high beam headlights. The advantages of HID headlamps include greater lighting power, daylight type lighting temperature and reduced power consumption. The low beam headlights provide an impressive 730 lumens of lighting power, and the light projection cut lines of the new HID headlights are extremely precise, providing maximum nighttime visibility without distracting other drivers.
ZDX also features Daytime Running Lights (DRL), which automatically turn on with ignition activation. DRLs have been proven to measurably improve daytime traffic safety by increasing the vehicle’s visibility to other motorists. Halogen fog lamps are also included as standard equipment on all ZDX trim levels.
Every Acura ZDX gets a camera that displays a rear view behind the vehicle. The standard ZDX display is a 3.5-inch diagonal image on a special screen within the rearview mirror, while the ZDX with the Technology Package or Advance Package displays an image on the in-dash Navigation screen. Furthermore, Technology and Advance Package models offer three different rear view angles-normal rear view, wide rear view and tow-friendly top view. The camera lens is located on the tailgate next to the license plate.
In another worldwide first, the ZDX uses a combined AM/FM/XM® antenna. The tri-band fin-type antenna is located on the rear area of the roof and uses a patented mounting structure, along with an aerodynamically efficient design that reduces aero drag as well as noise. The advent of this combined antenna eliminated the cost and complexity of using both a XM® antenna and an AM/FM in-glass antenna.
BLIND SPOT INFORMATION SYSTEM
Sensors for the Acura’s all-new blind spot information system are located behind the left and right rear bumper fascia. The sensors can detect other vehicles when they are in the blind spot of the ZDX driver. The feature uses indicators to alert the driver when another vehicle is detected in close proximity to the ZDX.
LED EXTERIOR LIGHTING
The Center High Mount Stop Lamp (CHMSL) features a single array of 12 LED diodes. The LED-design CHMSL array was used for its unique appearance as well as its ability to produce the required lighting brightness within the very slender physical dimensions of the light assembly. Four LEDs are also used in each of the ZDX’s outside mirror housing-mounted turn signals to improve visibility during lane changes or turns.
PANORAMIC GLASS ROOF
When viewed from above, the ZDX has the longest continual expanse of glass in the automotive market, stretching from the leading edge of the windshield to the trailing edge of the tailgate glass. A large component of this is the panoramic glass roof assembly, with a single sliding glass panel measuring 48.2 inches wide and 24.5 inches long. The ZDX’s moonroof opening is 25-percent larger than the one found in the BMW X6. To further brighten the cabin, a fixed glass panel over the rear seat area has the same dimensions as the movable front panel. Dual motorized sunshades cover both the front and rear panels should the ZDX occupants choose to reduce sunlight entering the interior.
The glass used for the roof panel is 4mm thick, and is tinted to provide privacy along with blocking 80-percent of all light (and 90-percent of UV sunlight) entering the ZDX cabin. When the roller shade is also extended, only 3-percent of overhead light will enter the cabin.
In contrast to most sunroofs and transparent moonroofs, the ZDX panoramic roof panel tilts and slides up and back across the outside of the vehicle’s roof. This helps to preserve maximum interior headroom while also retaining the dramatic and personal "sports coupe" design of the cabin greenhouse.
Because of its large size, the roof operating assembly required an inventive and sophisticated assembly process. Whereas most sunroofs assemblies are installed from inside the vehicle, the ZDX’s assembly-along with the entire glass roof panel-is pre-assembled and then, as a complete assembly, affixed to the roof of the vehicle from above using a combination of bolts and urethane adhesive. The entire glass panel is replaceable in the event it should be damaged.
A mesh fabric pop-up air deflector at the front of the ZDX’s roof opening is a first for Acura. The unique deflector achieves a new standard for wind-noise performance when compared to a traditional blade deflector-with a dramatic 10-decibel reduction in noise level as measured at 100 kph (62 mph). The noise reduction is due to airflow moving through as well as over the top of the deflector, which diminishes the booming noise that is common with a solid-style deflector panel.
The air deflector fabric is specifically designed to resist the buildup of dust, grit and organic matter such as insects. In testing, Acura designers drove the ZDX through the buggy Midwest at night, stored the vehicle for 10 days to let the assortment of insects on the deflector thoroughly dry, and then simply vacuumed them off.
A gloss-black rear spoiler is standard on the ZDX, with a larger black or body-colored rear spoiler available as a dealer-installed accessory. The spoilers are more than just a styling cue-they help air separate cleanly off the back of the vehicle, in turn reducing lift and helping the ZDX meet its aerodynamic targets that are important for both fuel economy and low NVH within the ZDX interior.
Construction of the ZDX tailgate represented a unique challenge due to its large size and its two glass components-a larger upper window and a smaller lower window. Two gas-charged struts support the tailgate, and power open/close operation is standard. The power function can be operated via the key fob remote, by a button on the instrument panel, or by a button located beneath the tailgate lip.
For safety, an anti-pinch feature is built into the power tailgate operation. Pressure-sensitive wiring, encased in a protective rubber sheath, encircles the tailgate; if the system senses an obstruction while closing, the tailgate will automatically reopen.
RESIN FUEL FILLER DOOR
The ZDX fuel filler door is unlocked when the driver’s door is unlocked, and is easily pushed open and closed from outside the vehicle. The fuel-filler door is made of a composite resin material that is lightweight, dent resistant and corrosion proof. For a fully finished appearance, the inside of the door is a flangeless resin design.
Beneath the aerodynamic front and rear fascias are two structural bumper beam assemblies to minimize damage during a collision.
In another first for the Acura Division, through-bumper, dual polygon-shaped exhaust outlets give the ZDX an even more premium look. The exhaust finishers are constructed of stainless steel, are polished to a high luster, and include integrated reflectors to help with nighttime visibility.
For the ZDX, Acura engineers wanted a mirror-smooth paint finish with a wet, glossy look. To improve the surface smoothness, "orange peel" (the finely undulating surface found on most paints) had to be greatly reduced.
To remain environmentally responsible, six waterborne exterior colors are available that use a durable clear-coat finish that resists scratching and airborne pollutants. In addition, a new painting cell was established in the factory to ensure that separately painted body panels-such as the ZDX’s front and rear bumper fascias-have excellent color harmony with the body.
"We really don’t know what to think of the ZDX. Acura has hit a home run with the interior appointments, chassis tuning, and cabin isolation. However, they swung and missed with second-row comfort, outward visibility, and fun-to-drive quotient. Targeted at the BMW X6, and marketed as a "Passionate Getaway" coupe for couples, the ZDX has been positioned in an awkward and rather diminutive niche."(AutoBlog)
The 2010 ZDX represents a completely new departure for Acura and demanded a fresh and creative interior that met the needs and desires of its target customers. Combining premium materials with a new standard of attention-to-detail and hand-craftsmanship, the ZDX’s interior takes its place as the ultimate expression of Acura interior design.
Right from its foundation, the ZDX’s interior package is aimed at a select demographic that has unique priorities and needs. ZDX customers want the style and excitement of a sports coupe, coupled with a good measure of cargo utility and all-season capability. Although a low priority, buyers don’t want to give up a comfortable sedan-like back seat for occasional use to accommodate passengers. In order of importance, the ZDX’s interior priorities are: front-seat passengers, rear cargo area and second-row passenger seating.
In terms of packaging, the ZDX design team developed a theme called "2+Freedom." That approach put the emphasis on the needs of the people in the two front seats, while giving them the loading freedom to easily accommodate a weekend golfing trip, or a piece of bulky cargo. For occasional use, they’d need a back seat that could comfortably accommodate two full-sized adults, or even three passengers for short rides. The rear cargo area offers 26.3 cubic feet of storage easily accessible via a power rear tailgate. For even greater space, the 60/40 rear seatbacks fold nearly flat to afford 55.8 cubic feet of cargo space.
An underlying theme throughout the design of the ZDX interior is its emphasis on the experiential aspect of driving. Features like the ZDX’s standard panoramic glass roof put passengers in touch with the environment they’re traveling through. Inside the ZDX, the materials set a new standard for Acura, and in some instances for the entire automotive industry. Details like the graceful sculpted leather panels on the instrument panel and console use new manufacturing processes and handcrafted wrapping techniques that allow fine leather to precisely follow complex, flowing interior shapes. Top grade leather is used in the ZDX and, in addition, many of the leather surfaces (such as on the instrument panel, center console and door panels) feature an exceptionally smooth top leather surface. LED interior lighting and a striking center instrument panel that blacks out when not in use give the ZDX a clean, technical feel. In the rear cargo area, the level of fit and finish sets a new industry standard with tightly tailored loop-type carpeting throughout, three separated hidden storage compartments and handsome satin alloy compartment latches that operate with tactile precision.
Standard equipment is comprehensive, with amenities like leather seating surfaces and a dual-zone, dual-mode, automatic climate control system that includes automatic humidity control and rear seat vents to help keep the entire passenger cabin comfortable. A supportive 10-way adjustable power driver seat and an 8-way adjustable power passenger seat are standard, as is the panoramic glass roof and a power tailgate.
Naturally, there is a long list of standard advanced technologies, including a powerful 8-speaker audio system with 6-disc CD changer, AM/FM radio, XM® Satellite Radio and Bluetooth® Audio. Also standard is USB port connectivity (for iPod®, iPhone®, or removable USB mass storage devices) and an auxiliary jack interface (for portable MP3 music players). The standard Bluetooth® HandsFreeLink® wireless telephone interface makes it easy to send and receive telephone calls on a compatible cellular phone without the driver needing to take his or her hands off the wheel or look away from the road. The rearview mirror includes an integrated rearview camera display.
The Technology Package adds a range of advanced features designed to offer drivers increased connectivity to the world around them and added driving enjoyment. A Keyless Access System with push-button start lets the owner enter and drive the ZDX without handling a remote-control fob or keys. Inside, luxurious full-grain perforated Milano premium leather covers the seating surfaces. The Acura Navigation System with Voice Recognition™ system uses an 8-inch full VGA high-resolution color display positioned high up in the center of the instrument panel where it is close to the driver’s line of sight while remaining shrouded from glare. With navigation data stored on a built-in hard disk drive (HDD) media storage device, the Navigation system boots up and operates with impressive speed. The navigation system includes AcuraLink Real-Time Traffic with Traffic Rerouting™ along with the AcuraLink Real-Time Weather™ including weather radar image maps. For the ultimate in connectivity, AcuraLink® Satellite Communication System allows direct communication between the ZDX and Acura, including the ability to make automated appointments for vehicle service.
Acura’s renowned Acura/ELS Surround® premium audio system is part of the Technology Package, featuring a 435-watt Digital Sound Processor amplifier, a 10-speaker surround sound array, and a built-in 15-gigabyte hard disk drive (HDD) media storage system that allows the ZDX owner to download and store about 3,500 songs* for later playback. The Acura/ELS Surround® premium audio system offers DVD-Audio, DTS™, CD, AM/FM radio, XM® Satellite Radio, Bluetooth® Audio, plus USB and auxiliary connectivity.
The available Advance Package interior includes everything in the Technology Package, and adds an upgraded premium brushed tricot headliner material, front power-ventilated seats, a sport steering wheel and LED ambient lighting in each interior door handle pocket. The Advance Package also includes controls and displays for the Collision Mitigating Braking System™ (CMBS™), Adaptive Cruise Control (ACC), Active Damper System and blind spot information system.
In most situations, ZDX owners will typically travel with just two people in the vehicle. As such, the interior is designed first and foremost to offer an optimized driving environment for front seat passengers. Consequently, front seat dimensions are sedan-like and similar to those of the TL, though the ZDX offers additional hip and shoulder room. The ZDX’s front seat hip point is closer to the floor than the TL’s, giving the ZDX a sportier, coupe-like flavor. The ZDX driver sits 1.2 inches higher than a TL driver, giving the ZDX a more commanding view.
Despite the ZDX’s taut exterior appearance, the rear seat is scaled to accommodate three adults. For increased headroom, the ZDX uses special head domes within the roof structure to give rear seat occupants added room. The sport-minded seats are supportive, comfortable and offer enough room for occasional longer trips.
STYLING AND MATERIALS
The ZDX interior forges a new direction for Acura, blending the signature Acura twin-cockpit design with rich materials. More than just pleasing to the eye, the ZDX interior is meticulously engineered to be appealing to the touch. Smooth, seductive premium leather wraps from the door panels, across the instrument panel (using new manufacturing techniques and hand crafting) and through to the center console. The design is a graceful blend of technology, driver connection and warm, relaxed personal space.
Details set the ZDX interior apart. Soft-touch materials line the door pull pockets, console and storage trays; floor mats are made of mixed-color loop carpet to conceal dirt and wear; the instrument panel, glove box, door trims and handles have a soft-touch feel; and alloy front and rear sill garnishes have a precision look.
The ZDX’s wrap-around leather trim required special engineering and attention to detail. Leather instrument panel trim has been used in the past, but the ZDX dashboard’s use of complex shapes and concave design had never been attempted before. Thus, a new build technique was required. Working with one of the finest leather crafters in Europe, Acura developed new manufacturing technology to allow the top quality leather to precisely trace the sweeping curves of the front doors, instrument panel and center console. Only the finest, unmarked leather hides are used in the process.
These premium hides are die-cut and split to a precise thickness, then hand-sewn. Bonded to a substrate to hold seam lines in perfect orientation, the leather is hand wrapped to the instrument panel and center console for precise alignment of all seams and cut lines. The end result is a warmly detailed interior appearance that meets Acura’s rigorous standards for durability.
The ZDX’s interior color palette reflects a progressive take on design. The interior is available in four different colors: Ebony, Taupe, Sumatra, and Umber
The ZDX features a driver-oriented cockpit that expands on Acura’s history of intuitive functionality. The wrap-around instrument panel design puts important systems and controls within easy reach of the driver. Supportive seating helps keep the driver securely in place during travel. The ZDX’s console-mounted straight gate shifter is intuitive to operate and racing-inspired paddle shifters on the steering wheel provide easy fingertip control of the new 6-speed automatic transmission. The 2010 ZDX features a sport-minded 4-pod instrument cluster; graphic digital displays supplement the main easy-to-read analog instrumentation. The ZDX’s many electronic features are designed to be simple to interpret and operate. Sight lines are clear with important items placed within easy view.
LEATHER-WRAPPED STEERING WHEEL
The ZDX’s power-adjustable tilt/telescope steering wheel is wrapped in premium smooth-grain leather with Euro Lancia-style stitching. Within fingertip reach are a pair of LED illuminated, racing-inspired paddle shifters that upshift and downshift the Sequential SportShift 6-speed automatic transmission.
The steering wheel incorporates the most commonly used controls, allowing the driver to keep hands on the wheel a larger percentage of time. Audio system controls are positioned on the left spoke, as are navigation system controls.
On the left spoke is a push-to-talk button to activate the voice recognition system that provides voice control of the navigation system, as well as operation of the climate control and audio system features. Also on the left are controls for Bluetooth® HandsFreeLink® system. Located on the right are controls for the MID and cruise control.
The Advance Package includes a unique sport steering wheel with a thicker diameter rim and larger shift paddles with grippy elastomer rubber backs and silver coloring. In addition, the steering wheel has an added Adaptive Cruise Control button on the lower right side and revised MID control buttons.
Straight-gate shifter assembly
The 2010 ZDX employs a straight-gate transmission shifter assembly (located in the center console) that has an intuitive, easy-to-use design. The shifter allows the driver to choose D (Drive), or S (Sport), the latter of which activates more aggressive transmission shift programming.
Given the ZDX’s sporting capabilities, it has front bucket seats designed to offer supportive comfort combined with secure lateral support needed during aggressive cornering. The ZDX’s front seats use padding that is specially tuned for ride comfort and isolation from road vibration. A supportive 10-way adjustable (8-way adjustable seat with 2-way adjustable lumber support) power-actuated driver seat is standard. All driver’s seat power adjustment settings (except power-adjustable lumbar support) can be stored in a pair of user profiles-one for each of the two key fobs that come standard with the ZDX. An 8-way adjustable power-actuated front passenger seat is standard and includes height and seat-cushion tilt adjustments for excellent comfort.
Leather seating surfaces with pebble-grain embossing is standard. ZDX models equipped with the available Technology Package or Advance Package are upgraded with full-grain Milano premium leather seating surfaces with perforated center sections for greater comfort.
All ZDX models have heated front seats. The driver’s side has heating elements in the base cushion and the seatback; the passenger seat has a heated base cushion. In the Advance Package, adjustable front seat ventilation is provided for greater comfort in warm weather. The all-new fan system pulls hot air away from the body and exhausts it under the seat cushion. Compared to traditional cooling seats that blow air upwards, the ZDX’s pull-style vent system cools occupants noticeably faster. Simple pushbutton control provides three levels of cooling and three levels of heating (Advance Package, Tech and Base have two levels of heat).
Active head restraints are standard for the ZDX front seats. In the rear seat, a convenient push-button release on each outboard headrest allows it to be manually folded down when not in use to provide an increase in rearward visibility. The center rear headrest is vertically adjustable for passenger comfort. For greater rear seat passenger comfort, a padded center armrest (with integrated dual cupholders) folds down from the center section of the rear seat.
When mixing passengers and cargo, the rear seatbacks offer the flexibility of 60/40 folding. A release handle positioned at the outboard side of each seatback allows the seatbacks to be easily folded down to create a nearly flat load floor.
MULTI-INFORMATION DISPLAY and Maintenance Minder™
Positioned between the tachometer and speedometer, a Multi-Information Display (MID) gives the ZDX driver instant access to important information. Controls positioned on the steering wheel allow the driver to cycle the MID display through multiple screens of information. With a large screen area, high resolution and the ability to display varying font sizes, the MID is clear and easy to interpret.
There are two individual trip computers built into the MID system, with easy tracking of overall mileage, individual trip mileage, average fuel economy, average speed, fuel range and elapsed time. The MID also displays outside air temperature as well as remaining percentage of engine oil life. The Maintenance Minder™ system alerts the ZDX driver of upcoming maintenance needs via the MID and should a fault occur with the vehicle, specific warning information will appear. The MID also allows the driver to set a variety of preferences for different ZDX systems.
When the ZDX is placed in Reverse gear, the view from a rear-mounted camera is displayed on a video screen built into a new auto-dimming rearview mirror. To make it easier for the driver to judge distance and clearance, solid yellow on-screen guidelines indicate the vehicle’s width, as well as distances of 1, 2 and 3 meters as measured from the rear of the ZDX. In addition, a dotted yellow line marks off the distance required to open the rear hatch. When equipped with the available Navigation system (as part of the Technology Package), a multi-view camera is standard and projects one of three different rear views on the 8-inch full VGA high-resolution color display. The primary view is "Normal View," which delivers 130-degrees of rearward visibility. For special conditions, there is the "Wide View," which delivers 175-degrees of rearward visibility. Finally, the "Top Down View" generates a straight-down look at the trailer hitch area or parking area- thus greatly easing alignment of the trailer and the ZDX’s available Class III towing hitch or helping when maneuvering in tight parking spaces.
The ZDX’s interior is designed to be functional and inviting at night. The speedometer cluster progressively illuminates to give the driver a welcoming feel upon entering the vehicle. When the door is opened, the instrument lighting comes on; then when the ignition is switched on, it brightens progressively to 100-percent illumination. The LED illuminated white instrument needles and indicator lights then come alive, indicating that the ZDX is ready to go. When the drive is over, the instrument lighting progressively dims.
All the interior lighting in the ZDX is via high-tech LED-with the exception of the glove box, console, courtesy and cargo lights. All of the ZDX’s interior switches are LED illuminated, making them easy to locate at night, including switches on all four door panels as well as the steering wheel and overhead console. The ZDX’s unique center stack is designed to be especially striking. With the vehicle off, the entire center stack blacks out for a "monolith" look. As systems are turned on (such as the audio system or climate control), LED illuminated labels on the individual control buttons appear.
In addition to front and rear LED overhead interior lights and fade-on/off LED map lights, the ZDX also has low-level LED interior cabin lighting. Calming blue ambient LED lighting in the ceiling illuminates the front center console while additional LEDs illuminate the front foot wells.
The glove compartment and the center armrest compartment are internally illuminated. The front doors and rear tailgate have courtesy lights that automatically illuminate when open. To prevent battery discharge, if any interior lights are left on, they will automatically turn off 15 minutes after the last door is closed, or will turn off instantly when the car is locked using the remote.
The ZDX interior offers an array of storage and convenience features for the driver and passengers. The front center console is internally illuminated, includes a 12-volt power point and a USB port that allows for easy connectivity of an iPod®, iPhone® or a removable mass storage device. The USB port is located alongside a traditional AUX jack (that allows connectivity of MP3 music players) in the center console.
A leather-covered padded armrest tops the console, and includes a slide-out tray that is ideal for holding a cell phone, iPod® or other small items. A double cupholder is positioned ahead of the console, and can accommodate large beverage cups and bottles. A satin silver cover conceals the cupholders when they’re not in use. Rear-seat passengers have a fold-down padded center armrest with a pair of covered cupholders.
Inside the glove compartment is a separate document shelf that allows the convenient storage of the ZDX User Manual as well as important papers such as registration and insurance. The separate document shelf arrangement not only keeps paperwork neatly contained, but it also frees up storage space in the main glove box compartment. Total glove compartment capacity is 0.28 cubic feet. The ZDX’s headliner-mounted console includes sunglasses storage along with controls for interior lighting, HomeLink® and the moonroof.
REAR CARGO AREA
The ZDX’s impressively detailed rear cargo area gets its inspiration from a high-end modern "destination hotel" guest room, where clean lines conceal hidden functionality. Open the power-actuated tailgate and the level of finish of the ZDX cargo area is immediately apparent. Lined with premium loop carpet, the cargo area has tight panel fits like those in the passenger portion of the interior. A cleverly hidden 2.2 cubic-feet cargo bin is positioned in the floor and has a satin-metal handle with a precise action. The lid is assisted by two gas struts to make opening easy. Hidden behind removable panels are additional storage areas positioned on the left and right sidewalls of the cargo compartment. The removable side panels have satin-metal release handles, and the panels can be stored in the central cargo bin to open up a wide load space designed to accommodate up to four golf bags laying crosswise. A recessed tailgate latch mechanism and dual alloy scuff plates combine with a comfortable lift-in height to minimize the chance of damage to cargo, or to the vehicle, while loading.
The rear cargo area offers a total of 26.3 cubic feet of space behind the rear seats, including the volume of the floor and side compartments. If even more space is required, the second-row 60/40 folding seatbacks can be lowered. With the seats down, the ZDX offers a near-flat fully carpeted load floor and a total of 55.8 cubic feet of cargo space-including the rear-seat foot space.
DUAL-ZONE, DUAL-MODE ADAPTIVE CLIMATE CONTROL SYSTEM
The 2010 ZDX has a dual-zone, dual-mode adaptive climate control system with air filtration that lets the driver and front passenger independently set temperature modes to their individual liking. Rear-seat occupants are kept comfortable by adjustable vents located in the rear of the center console.
For greater passenger comfort in cool climates with bright sunshine, the system can deliver disparate temperature output to different parts of the cabin. For example, areas of the interior that are warmed by the sun will receive cooler air via the dashboard vents whereas the front footwells that are in shade will be supplied with warmer air.
In addition, Acura’s automatic humidity control technology allows the HVAC system to automatically adjust humidity control based on specific conditions. This patented system predicts the condition in which window fogging is likely, then lowers humidity in the interior by orchestrating the air conditioning, air outlet mode, temperature and fan blower speed. The system can also improve passenger comfort during cold winter driving by increasing cabin humidity-thus accounting for the very dry air usually experienced during the winter months. To increase the amount of cabin humidity, the air conditioning system cycles on/off. As a side benefit, less use of the air conditioner reduces fuel consumption.
ZDX models with the Technology Package or Advance Package use the GPS navigation system to contribute to overall passenger comfort thanks to a 3D solar-sensing feature. The navigation system determines the position of the sun relative to the driver and passenger based on continuously updated vehicle position information. Combined with information from a solar sensor located on top of the instrument panel, this feature lets the climate-control system automatically adjust the temperature and air outlet mode from side to side as needed to compensate for asymmetrical solar heating.
8-SPEAKER AUDIO SYSTEM WITH 6-DISC CD CHANGER, AM/FM/XM® AND BLUETOOTH® AUDIO
Built in concert with Panasonic, the ZDX audio system (non Technology Package or Advance Package equipped models) is an 8-speaker design with a 6-disc CD changer, AM/FM radio, XM® Satellite Radio and Bluetooth® Audio. The system can also read MP3 and WMA files on CDs and includes the Radio Data System (RDS) and Speed Volume Control (SVC).
The ZDX’s 266-watt audio system’s Digital Signal Processing (DSP) amplifier drives a titanium-dome tweeter mounted in each A-pillar and a 3-inch Super Dynamic Range speaker positioned in the top in the instrument panel. 6.7-inch mid-range speakers are positioned in each front and rear door. A big 8-inch diameter downward-firing subwoofer is placed under the cargo floor in a specially tuned 25-liter acoustic enclosure. This unusually large enclosure provides improved bass response and extends frequency range from 20 Hz down to an amazingly low 16Hz-all with very low harmonic distortion.
The audio system offers USB port connectivity for iPod®, iPhone® or removable USB mass storage devices. The USB port is powered and can charge a device while simultaneously transferring information to the audio system. USB-connected devices can be operated via the audio controls, with filenames and folders appearing on the audio system’s text display. The ZDX’s audio system can also play Bluetooth® Audio when paired with a compatible device. Bluetooth® Audio is a wireless music transfer format that is separate from Bluetooth® HandsFreeLink® that is used for telephone voice communication. The ZDX also has an auxiliary (AUX) jack connection enabling use of portable MP3 music players. The AUX connection requires the music player to be controlled via the device’s own interface (though the ZDX’s audio system can control volume).
XM® Satellite Radio
XM® Satellite Radio is a standard feature within the 2010 ZDX audio system and it provides more than 170 channels of digital programming with near CD-quality sound. The XM® broadcast signal is beamed to two broadcast satellites positioned in geostationary orbit more than 22,000 miles above Earth. The beams from these two broadcast satellites (one located over the west coast, one over the east coast) combine to span the entire continental United States and some of Canada. There are also more than 1,000 ground antennas to help boost the XM® signal in metropolitan areas where tall buildings can block satellite signals.
XM® programming includes channels devoted to music, sports, talk, traffic, weather, children’s programming and entertainment. Of the more than 170 XM® channels, 69 are commercial-free. When the ZDX’s audio system plays XM®, the display screen shows the current station, song title, or artist’s name. A complimentary three-month subscription to the XM® service is included with purchase of a new ZDX, and customers are able to continue the service or cancel any time afterwards.
BLUETOOTH® HANDSFREELINK® WIRELESS TELEPHONE INTERFACE
All Acura vehicles have a standard Bluetooth® HandsFreeLink® hands-free telephone interface that is designed to work with a wide variety of Bluetooth® enabled mobile telephones. Bluetooth® is a radio frequency-based technology that allows portable devices (such as cellular telephones, PDAs, laptops and other devices) to communicate wirelessly over a limited distance. The ZDX’s HandsFreeLink® system is compatible with Bluetooth®-enabled cellular phones that have the Hands Free Profile (HFP). (Some early Bluetooth®-enabled phones do not have this communications protocol, but most newly released phones have HFP.) After the driver completes a one-time pairing process, the ZDX can communicate wirelessly with the driver’s cell phone when it is within approximately 10 feet of the vehicle. The telephone needs to be on, but can be stowed in a pocket, briefcase, purse, or anywhere inside the ZDX cabin.
With Bluetooth® HandsFreeLink® the driver can answer or make telephone calls without removing their hands from the steering wheel. When a call comes in, the incoming caller’s telephone number is displayed on the Multi-Information Display (MID) located between the tachometer and speedometer. In addition, a phone ring tone can be played over the audio system. If the driver chooses to answer the phone call, a press of the steering wheel-mounted "Pick up" button mutes the audio system and the incoming caller is heard over the ZDX’s audio system speakers. Working with a special overhead array microphone, the HandsFreeLink® system cancels "echo effect" and reduces background noise to improve the transmission quality of the driver’s speech.
By activating the Bluetooth® HandsFreeLink® system using fingertip controls mounted on the steering wheel, the driver can dial a telephone number by voice. The driver also can store frequently called numbers in the system’s memory using unique voice tags. Up to six different compatible mobile phones, each with a unique "user profile", can be paired with the ZDX’s Bluetooth® HandsFreeLink® system at one time. Each phone profile has its own password-protected call history, phonebook, speed dials and voice tags. With a single paired phone and the proper password for each profile, a user can access any of the other profiles. This convenient feature means that a person who carries both a work cellular phone and personal phone can easily access both profiles from either phone.
When equipped with the Navigation system (Technology Package or Advance Package), some HandsFreeLink® functions are displayed on the high-resolution navigation system screen. This provides a versatile interface for HandsFreeLink® operation. The system can also import a compatible cellular telephone’s phonebook (over 1,000 entries), allowing the data to be more easily searched via the 8-inch full VGA high-resolution navigation screen.
ACURA NAVIGATION SYSTEM WITH VOICE RECOGNITION™
ZDX models equipped with the Technology Package or the Advance Package have the latest generation Acura Navigation System with Voice Recognition™ which features a new multi-view rear camera.
The Acura Navigation System with Voice Recognition™ tracks the ZDX’s position based on positioning data from up to 12 orbiting Global Positioning Satellites (GPS). If GPS reception is blocked by a tall building, tunnel, or parking garage, an internal gyroscopic system with a speed sensor tracks the location to keep the mapping information current and reliable until satellite reception is restored.
The ZDX’s navigation system stores its mapping data on an internal hard disk drive (HDD) media storage system. The same drive is also partitioned and used by the audio system to store audio files. Much faster than the DVD drive used on many other systems, the ZDX’s new hard drive is the key to the system’s impressive search and routing speed. The system can be updated annually with the latest mapping information by inserting an update disc into the audio system’s slot-loading CD/DVD drive.
The navigation system can be controlled by using the interface dial by choosing menu options or by spelling out a word (e.g., an address, business name or place). Characters on an on-screen keypad can be selected using the Interface Dial. For voice operation, the driver simply presses the "Talk" button on the steering wheel and says any of a number of preset command phrases. The system responds to over 700 command phrases, as well as to spoken city and street names. Voice recognition capability saves time and simplifies operation of the system.
The audio system is automatically muted when the "Talk" button is pressed, and an overhead array microphone receives the command from the driver. Commands can be given in plain English, like "Display gas stations," "Find nearest hospital," or "Find nearest Chinese restaurant." The 2010 ZDX’s voice recognition technology allows the owner to simply speak city and street names aloud, and the system responds by displaying matches available in the database. Points of interest on the map (such as restaurants or grocery stores) can be displayed or you can have the system provide turn-by-turn navigation – all by voice command. The massive point-of-interest (POI) database includes telephone numbers, which can be dialed by using the Bluetooth® HandsFreeLink® system or with the driver’s cellular telephone.
Wallpaper image display
To further customize the ZDX’s interior, the navigation system allows the storage of up to 10 images each for each driver (two drivers total) on the built-in hard disk drive (HDD) media storage system. Any one of the stored images can be displayed as a full-screen image on the navigation display when the display is not otherwise in use. To avoid driver distraction, there is no "slide show" function. J-peg images can be loaded from a computer onto a USB storage device, such as a thumb drive. Then the thumb drive can be plugged into the ZDX’s USB port that is located in the center console. Using on-screen menus, the images can then be transferred to the ZDX’s internal HDD. Each driver can then choose among their stored images for display, or set the system to not display wallpaper.
AcuraLink® Satellite Communication System
The Technology Package or Advance Packages include the AcuraLink® Satellite Communication System (within the 48 contiguous United States). AcuraLink® allows two-way communication between Acura and the ZDX, providing customers with the latest information specific to their vehicle. Once the owner has enabled its data-transmission function, the owner’s Bluetooth® telephone is used in cases where communication from the car to the Acura Telematics server is needed. In addition, while driving, the AcuraLink® system conveniently allows the ZDX owner to make automated appointments for vehicle service. The data connection from the server to the vehicle is enabled even if the monthly XM® service package is not in effect.
Each AcuraLink® message is prioritized by importance; high priority messages are displayed immediately while normal messages trigger a message icon on the navigation display. To avoid distraction, some low priority messages show up only on vehicle start-up. The owner can choose to read or listen to a message immediately, or archive it to be retrieved at a later time. AcuraLink® messages consist of a limited amount of text plus expanded details via Text-To-Speech.
Messages that can be sent to the ZDX include Maintenance Minder® (detailed information regarding the next required maintenance), Quick Tips (information to help maximize the benefit of ZDX features), Feature Guide (supplements to the ZDX Owner’s Manual) and Diagnostic Info (detailed information and instructions should an onboard system issue arise). The ZDX owner has complete control over the types of messages they receive. All AcuraLink® preferences can be set via the Owner Link™ website (www.ahm-ownerlink.com).
AcuraLink® can provide the owner with important information that previously has been unavailable. For example, if a warning light should appear on the ZDX instrument panel, AcuraLink® can automatically send a trouble code along with the sensor data associated with the fault to the Acura Telematics Server. The code is analyzed, and a message is sent back to the ZDX – such as "A software issue has been detected. It is OK to continue driving. The repair is currently being developed, so you do not need to visit your dealer at this time." A separate AcuraLink® message will be sent to the ZDX when it’s time to visit the dealer to have the system repaired. AcuraLink® can tell the owner if a particular fault is serious enough to cancel a trip, if it can be dealt with later or if it requires special driving techniques.
MULTI-VIEW REAR CAMERA
When equipped with the available Navigation system, the ZDX has a multi-view rear camera. When the ZDX is placed in Reverse gear, a Normal View generated from a rear-mounted camera is displayed on the 8-inch full-VGA color monitor. To help the driver to judge distance and clearance, solid yellow on-screen guidelines indicate the vehicle’s width, as well as distances of 1, 2, and 3 meters from the back of the ZDX. In addition, a close proximity dotted yellow line is positioned at a distance of 0.5 meter.
In addition to Normal View, the driver can select Wide View or Top View simply by pushing the interface dial. When the vehicle is in Reverse, Wide-View mode is ideal when backing out from a parking space where vehicles approaching from the sides pose a threat. Top View provides valuable clearance information when backing into a confined space or when trying to align the tow hitch with a trailer.
When set to Wide or Normal View, each time the vehicle is restarted, the system displays the previous viewing angle. However, if the vehicle is turned off while in Top View, during the next restart the system automatically reverts to Normal View.
KEYLESS ACCESS SYSTEM
ZDX models with the Technology Package or Advance Package have the latest generation of Acura’s Keyless Access System (with smart entry and pushbutton ignition). The enhanced system identifies one of two drivers each time the driver’s door is opened (even if it is already unlocked) then sets within the ZDX’s memory a multitude of features to a custom profile preset by that driver. The system sets the driver’s seat, steering wheel, outside mirrors, climate control, audio system presets, select navigation system settings and the HandsFreeLink® Profile.
In the event both owners approach the car at the same time, the ZDX will set the vehicle preferences of the Keyless Access Remote that approaches the driver’s door.
The Keyless Access System has a unique digital identity that lets the ZDX owner gain access to the car without ever having to unlock it with the remote transmitter or a conventional key. With the Keyless Access Remote in his/her possession, the car can be unlocked when the driver pulls one of the front door handles. When carrying the fob (or if all doors are unlocked), the tailgate can be opened by pulling the tailgate release switch located above the rear license plate.
Once the driver has opened the door and is seated, the Keyless Access System allows the ZDX to be started by pushing the brake and then pushing the Engine Start/Stop button positioned on the instrument panel. When leaving the car, a press of the soft-touch button on the outside of the door handle or tailgate locks all the doors. Alternatively, a press of the Lock button on the Keyless Access Remote will simultaneously lock all the doors. The Keyless Access System will not allow the recognized transmitter to be locked in the interior of the ZDX.
The Keyless Access System also features a unique "quick vent" feature (activated by pressing the Keyless Access Remote "unlock" button two times and then holding it) that automatically lowers all side windows as well as opens the power panoramic glass roof to quickly vent built-up interior heat. In addition, turning the key in the driver’s door key cylinder to the "lock" position twice (and then holding it the second time), simultaneously closes all open windows and the dual moonroof.
The ZDX will signal the driver when the remote battery is low. A built-in mechanical key is provided as a back up to enter vehicle in the event that the Keyless Access Remote battery should fail. Once inside, the driver can start the car by placing the fob in an illuminated remote port near the engine STOP/START button.
The 2010 Acura ZDX offers an Advance Package that includes all items in the Technology Package and adds:
- Adaptive Cruise Control (ACC)
- Blind spot information system
- Heated and ventilated front seats
- Premium brushed tricot headliner material
- Sport steering wheel
- LED ambient door handle illumination
ADAPTIVE CRUISE CONTROL (ACC)
The ZDX with the Advance Package includes the Collision Mitigating Braking System™ (CMBS™) and Adaptive Cruise Control (ACC). ACC is a vehicle speed and distance control system that uses a grille-mounted millimeter-wave radar unit to monitor the distance between the ZDX and the vehicle directly ahead. Like a conventional cruise control system, the ZDX’s ACC can maintain a pre-set speed. In addition, by combining radar data with data from speed sensors, ACC can regulate the ZDX’s speed to maintain a pre-set following distance interval between it and the vehicle directly ahead. The system is designed for use on open highways and works only when the ZDX is traveling over 25 miles per hour.
Pressing the "ACC" button below the right-hand spoke of the steering wheel activates the system. When this button is pushed, "ACC" will appear on the Multi-Information Display (located between the tachometer and speedometer) indicating that the ACC system has been turned on. To select the ACC cruising speed, the driver accelerates to a chosen speed and presses the "Decel/Set" button located on the right-hand spoke of the steering wheel. Once selected, the cruising speed is shown on the Multi-Information Display.
The following distance interval is selected by pressing the "Distance" button on the lower right spoke of the steering wheel. Using this button, the driver can choose one of three following intervals: approximately 1 second, 1.5 seconds or 2 seconds, based on the speed of the ZDX along with the following distance the driver wants to maintain from the car directly ahead. Each time the button is pressed, a "vehicle-shaped" icon on the Multi-information display changes to reflect the chosen following interval:
- One bar representing approximately a 1-second interval
- Two bars representing approximately a 1.5-second interval
- Three bars representing approximately a 2-second interval
Once ACC is activated, the system’s electronic control unit (ECU) adjusts the throttle or applies light braking to maintain the chosen following distance interval between the ZDX and the vehicle directly in front of it. If a vehicle from another lane cuts in front of the ZDX (between the ZDX and the car that it has been following) the ACC system will beep and a "vehicle" icon will flash on the Multi-Information Display to alert the driver that a new vehicle has been detected. The ACC system then adjusts the throttle and/or applies braking to maintain the pre-set following interval between the ZDX and the new vehicle. A vehicle icon will appear each time a vehicle moves into the ACC system’s range. Conversely, when a vehicle moves out of the ACC system’s range, the vehicle icon changes to an "outlined" image.
If the vehicle directly ahead of the ZDX brakes suddenly, a series of beeps will sound and the word "BRAKE" will appear on the Multi-Information Display warning the driver to apply the brakes. If the vehicle directly in front of the ZDX accelerates out of the radar’s detection zone or moves to another lane, and another vehicle is not within the system’s range, ACC will accelerate the ZDX until the pre-set cruising speed is achieved.
When a vehicle moves out of range, the "vehicle icon" on the Multi-Information Display will change from solid to outline. The driver can switch between ACC and conventional cruise control by holding down the "Distance" button located on the steering wheel for five seconds. Cruise control system status is displayed continuously on the Multi-Information Display.
Because rain, snow, fog and other types of inclement weather can affect the ACC system’s millimeter-wave radar, the ACC system should not be used during these conditions.
BLIND SPOT INFORMATION SYSTEM
The ZDX’s available Advance Package includes the blind spot information system. A pair of sensors (one on each rear corner of the vehicle) can detect nearby vehicles that may be positioned in the driver’s blind spot. If the ZDX’s turn signal is on in the direction of a detected blind-spot object, an indicator located on the inside A-pillar garnish flashes to catch the driver’s attention.
To prevent false alarms while maneuvering at low speed, the system is disabled below approximately 6 mph. The system can also be manually switched off by the driver using a switch is located on the instrument panel to the left of the steering wheel.
2010 ZDX INTERIOR ACCESSORIES
A line of Acura Genuine Accessories was developed simultaneously with the ZDX to provide personalization for the Acura owner. Like all Acura Genuine Accessories, the ZDX accessories are covered by a 4-year/50,000-mile limited warranty when installed at the time of initial vehicle purchase.
To deliver a seamless blend of power, refinement and efficiency, the ZDX features the latest-generation Acura 3.7-liter VTEC® V-6 engine. As large as any engine in the Acura product line, the all-aluminum powerplant has single overhead camshaft cylinder heads and 24 valves, with the intake valves actuated by Acura’s acclaimed VTEC® (Variable Valve Timing and Lift Electronic Control®) system. The compact and efficient engine produces 300 horsepower and 270 lbs-ft of torque, with special emphasis on mid-range torque for outstanding overall driving character.
The ZDX’s evolved 3.7L V-6 uses a more rigid cylinder block, high-strength crankshaft, heavy-duty connecting rods, high compression-ratio pistons, cylinder heads with improved cooling, exclusive camshaft specs, a new 2-rocker arm design VTEC® valvetrain system, more performance oriented camshaft specs when in VTEC®, new intake valve springs, a new EGR system, unique long-reach spark plugs, a larger throttle body among other features.
The engine reflects Acura’s unwavering commitment to the environment with excellent fuel efficiency given its power output. Internal fuel economy testing predicts that the ZDX will achieve an EPA city/highway fuel economy of 16/22 mpg*-which would give it a best-in-class combination of economy and power. For all its performance, the ZDX’s V-6 is also very clean. It meets EPA TIER 2-BIN 5 and CARB LEV II ULEV emission standards, and has close-coupled catalytic converters to ensure efficient cold-start emissions control.
The 3.7L V-6 is coupled with a brand-new Sequential SportShift 6-speed automatic transmission along with a new multi-clutch torque converter. With comparatively "short" gearing in the first five forward gears, acceleration is enhanced- while fuel economy and quiet cruising are optimized with a relaxed Sixth gear ratio. The transmission offers two automatic shift modes, or can be operated manually via racing-inspired steering wheel paddle shifters. Grade Logic Control, Shift Hold Control and Cornering G Shift Control make the new 6-speed the most advanced automatic transmission ever offered by Acura.
The 2010 ZDX features Super Handling All-Wheel Drive™ (SH-AWD®), Acura’s advanced drivetrain system that delivers quick, precise all-wheel-drive response. SH-AWD® distributes the optimum amount of torque not only between the front and rear axles, but also between the left and right rear wheels. The system’s unique torque vectoring direct yaw control feature helps make the ZDX exceptionally neutral handling under power, for greater handling precision and control. Along with its dry-pavement handling advantages, the ZDX’s SH-AWD® system also offers excellent all-season capability and requires no driver intervention in operation.
The ZDX’s 3.7-liter V-6 engine employs an inherently smooth-running 60-degree V-angle. The cylinder block is constructed of aluminum and has high-silicon aluminum cylinder liners for added weight savings and excellent cooling. The cylinder heads are cast of lightweight aluminum and feature four valves per cylinder along with a VTEC® variable valve timing system with variable lift and timing for the intake valves. Power is enhanced with a higher 11.2:1 compression ratio, revised high-output port designs, intake airflow optimization and a sport-tuned exhaust system. In addition to a high power output, the 3.7-liter V-6 delivers good fuel economy and low emissions.
The engine block of the 3.7-liter ZDX is constructed of lightweight die-cast aluminum. The cylinder liners are made of high-silicon aluminum and are cast directly into the aluminum block. The hard piston ring sealing surface of the liners is created during manufacturing with a mechanical etching process that exposes silicon particles embedded in the sleeves. The aluminum sleeves provide better cooling, thus allowing closer piston-to-cylinder clearance than iron liners afford.
The cylinder block is heat-treated for strength and has a deep-skirt design with four bolts per bearing cap (providing excellent structural support for the crankshaft), thus minimizing engine noise and vibration. The ZDX uses the latest version of the 3.7L V-6 that features improved cylinder-block rigidity and stronger/stiffer mounting points that team to further reduce NVH. Adding further rigidity and improving reliability is a new cast-aluminum oil pan that works with a new oil pump assembly.
The ZDX’s 3.7L V-6 engine employs a crankshaft that features higher quality (and subsequently stronger) forged steel for improved strength. New 11.2:1 compression ratio forged aluminum pistons replace the previous 3.7L’s 11.0:1 pistons, and the pistons are cooled with oil spray directed up to the underside of the piston crowns, making possible the high compression ratio. In addition, the pistons feature a new 2-piece oil ring assembly that improves durability. Just as with the previous 3.7L, the connecting rods are steel forgings for high strength, but the latest version of the rods feature a wider beam width for improved strength. A unique "crack separated" build process (in which the bearing caps are broken away from the rod rather than machined separately) allows for a lighter, stronger connecting rod with perfect mating surfaces.
The 3.7-liter engine has lightweight aluminum cylinder heads that are pressure cast for high accuracy and low porosity. Each cylinder head uses a single camshaft, turned by an Aramid-fiber reinforced toothed belt drive for long service life. To save weight and reduce parts count, the cylinder heads have uniquely integrated exhaust-port castings that provide optimal positioning of the close-coupled catalytic converters, one on each cylinder bank. This design results in more rapid "light off" of the catalytic converters on cold start-up for reduced start-up emissions. Unique long-reach spark plugs are now used in the cylinder heads that promote improved combustion for lower emissions and improved mid-range torque.
The cylinder-head castings feature port flow optimization for improved performance, while an upgraded water pump teams with revised cylinder head coolant flow for improved cooling performance. Upgraded intake valve springs are used to match the revised camshaft specs for the intake valves during VTEC® operation. The cylinder heads are sealed against the block with a new 3-layer, shim-type head gasket.
VTEC® (VARIABLE TIMING AND LIFT ELECTRONIC CONTROL)
The ZDX engine uses the VTEC® system, providing strong low-speed torque, crisp throttle response, and enhanced high-rpm power. This is achieved by providing reduced intake valve lift and duration at low engine speeds for good torque, with increased intake valve lift and duration at higher rpm for optimum power.
The ZDX features a new 2-arm version of the Acura VTEC® rocker arm system that provides 2-mode control of the intake valves. Variable operation of the engine’s intake valves are controlled for optimal volumetric efficiency, air/fuel mixing, burn rate and exhaust flow. The 2-arm VTEC® rocker arm itself is smaller and has less mass than the previous design.
At 4,800 rpm, the Powertrain Control Module (PCM) electronically triggers the opening of a spool valve that routes pressurized oil to small pistons within the intake valve rocker arms. Moved by this pressurized oil, the pistons lock each cylinder’s pair of intake rocker arms together. The linked intake rockers then follow a single high-lift, long-duration cam lobe- an intake lobe with more lift and duration than used with the previous 3.7L V-6. The VTEC® high-lift mode increases intake valve lift by 28-percent and valve opening duration by 35-percent-an increase of 5- and 3-percent (respectively) versus the 3.7L V-6 engine used in the 2009 ZDX.
To maintain the ZDX’s refined operating characteristics, careful intake and exhaust helps to make the VTEC® changeover smoother and quieter for a seamless driving experience that’s nearly undetectable to the driver and passengers.
DRIVE-BY-WIRE™ THROTTLE SYSTEM
The ZDX does not use a conventional mechanical throttle linkage, but instead employs sophisticated electronics to provide the connection between the throttle pedal and the engine’s throttle-body. The result is more accurate and precise throttle control, along with less clutter and reduced weight under the hood. By programming such factors as "gain" and "tip-in" into the throttle actuation, engine response and drivability can be tailored to suit specific driving conditions.
Acura’s Drive-by-Wire™ throttle system monitors pedal position, throttle-body opening, engine rpm, and road speed to establish driving conditions in real time. This data is used to define the throttle control sensitivity necessary to provide the predictable and responsive feel corresponding to driver expectations.
The Drive-by-Wire™ throttle system also helps integrate engine functions with the Vehicle Stability Assist™ (VSA®) and traction control system. To smooth downshifts, the system is programmed to "blip" the throttle to help match engine speed to gear speed within the all-new Sequential SportShift 6-speed automatic transmission.
PROGRAMMED FUEL INJECTION (PGM-FI)
The Programmed Fuel Injection (PGM-FI) system continuously tracks many engine parameters including crankshaft and camshaft positions, throttle position, intake air temperature and mass flow rate, engine coolant temperature and manifold pressure-and then the PGM-FI system adjusts fuel delivery accordingly to deliver the best combination of power, fuel economy and low emissions. Fit to the latest version of the 3.7L V-6 is a new, more accurate airflow sensor that improves performance while simultaneously reducing emissions.
MULTI-HOLE FUEL INJECTORS
Special multi-hole fuel injectors mounted in the lower intake manifold spray directly toward the intake ports. The multi-hole injector design means that fuel droplet size is reduced for better fuel atomization, resulting in improved cold weather start-up, better fuel economy, lower emissions and higher horsepower.
2-PIECE DUAL-STAGE INTAKE MANIFOLD
The ZDX features a dual-stage intake manifold made from lightweight magnesium-alloy. The manifold works together with VTEC® to improve low-speed torque with no sacrifice in high-rpm power. Divided into two banks feeding three cylinders per bank, the manifold has two Powertrain Control Module-controlled butterfly valves located between each bank. These closed valves separate bank-to-bank plenum chamber and improves the resonance charge effect. The result is an amplification of pressure waves within each half of the manifold at lower engine speeds, improving low rpm torque. The open ends of the intake runners are also flared into a "trumpet" shape (as on racing engines) to further improve airflow.
The butterfly valves open above 4,050 rpm, connecting the two halves of the intake manifold, increasing its effective volume. The manifold’s two modes further complement the changes in low and high rpm running made possible by the VTEC® system.
DIRECT IGNITION AND DETONATION-KNOCK CONTROL
Because accurate ignition spark timing is crucial for best power and torque output as well as reduced emissions, the Powertrain Control Module (PCM) continually monitors several engine parameters to determine optimum spark timing for all driving conditions.
A strong ignition spark is critical to improve power and reduce emissions. Thus, the new 3.7L V-6 employs upgraded spark-plug hole coils and special long-reach spark plugs. Additionally, a block-mounted acoustic detonation (knock) sensor "listens" to the engine, sending information about potentially damaging detonation to the PCM, which then incrementally retards ignition timing to help prevent damage. Individual coil units positioned directly above each iridium alloy-tipped spark plug compliment the ignition system. The spark plugs require no scheduled service prior to 100,000 miles of use. To help improve misfire detection, the new 3.7L V-6 uses a new high-resolution crankshaft pulser that generates more accurate timing information.
HIGH-FLOW EXHAUST SYSTEM WITH CLOSE-COUPLED CATALYTIC CONVERTERS
The ZDX’s 3.7-liter engine has exhaust manifolds that are cast directly into the cylinder heads for lighter weight, reduced parts count and less bulk. Attached directly to the cylinder heads are high-efficiency, free-flowing 600-cell/in2 catalytic converters. Due to closer-than-normal proximity to the exhaust ports, the close-coupled catalytic converters "light off" very quickly after the engine starts, better reducing emissions in the critical start-up mode. To ensure optimum flow and low backpressure, a hydroformed two-into-one collector connects the close-coupled catalytic converters to the main 350-cell/in2 under-floor catalytic converter.
The ZDX’s high-flow exhaust system splits just past the under-floor silencer. To provide clearance for the all-wheel-drive system’s rear-mounted differential, one exhaust pipe is routed on each side of the driveshaft and feeds into a high-flow muffler on each side of the ZDX. Dual outlets, one on each side, are integrated into polished stainless-steel finishers positioned in the rear fascia. For corrosion resistance, the entire exhaust system, including pipes, silencers, chambers and hanger rods is constructed of stainless steel.
The ZDX meets stringent EPA TIER 2-BIN 5 and CARB LEV II ULEV emission standards, and is certified to this standard for 120,000 miles of service.
Acura’s advanced technologies contributing to this performance are the close-coupled catalytic converters which light-off quickly on start-up, a high amount of EGR gas recirculated into the engine, and an advanced 32-bit RISC microprocessor within the Powertrain Control Module (PCM) that boosts computing power to improve the precision of fuel and spark delivery at all engine speeds and conditions.
Particularly in the critical post-startup mode, the high-efficiency multi-hole fuel injectors deliver better fuel atomization for lower emissions.
The engine features Programmed Fuel Injection (PGM-FI) that continually adjusts fuel delivery to achieve the best combination of power, fuel mileage and low emissions.
ONE-TOUCH STARTER SYSTEM WITH HIGH-POWERED STARTER
The ZDX engine features a high-powered starter to crank the engine. In addition, it employs a one-touch system that automatically maintains starter engagement until the engine has started. The driver simply turns the key momentarily (or pushes the START/STOP button when equipped with the Technology Package or the Advance Package). The system cranks the starter until the engine starts and then disengages the starter automatically.
NOISE, VIBRATION AND HARSHNESS (NVH) CONTROL
The ZDX powertrain is designed to effectively control Noise, Vibration and Harshness (NVH). Cylinders with a 60-degree V-angle, a high-rigidity die-cast engine block, strong forged-steel crankshaft, die-cast accessory mounts and stiff cast aluminum engine oil pan, all work together to ensure low engine NVH. Electronically Controlled Mounts (ECM) at the front and rear of the transversely oriented engine block have two firmness settings that are softer at low speeds (for improved comfort) and firmer (for improved performance) as engine speed rises.
100,000-MILE TUNE-UP INTERVAL
The ZDX is an exceptionally low-maintenance vehicle. With features like Iridium alloy-tipped spark plugs and a space-saving, self-tensioning serpentine accessory drive belt, the engine requires no scheduled maintenance until 100,000 miles-with the exception of periodic inspections and normal replacement of fluids and filters. The first scheduled tune-up at 100,000 miles includes valve adjustment, timing belt replacement and water-pump inspection. Exact mileage for engine service is determined by actual driving conditions.
The ZDX has a Maintenance Minder™ system to monitor operating conditions and to alert the driver should maintenance be required. When the ignition is first turned on, the Multi-Information Display (MID) located between the tachometer and speedometer shows maintenance information, if required. To avoid driver distraction, the display is not shown while driving. The MID indicates the remaining percentage of engine oil life, and indicates when service is due with a "wrench" icon. A percentage-based countdown to the next service is displayed when the car is within 15-percent of the end of the service interval. The type of service required is shown in an alphanumeric code, and if a service is missed, the MID indicates its urgency by showing past-due mileage.
The owner-resettable system monitors all normal service parts and systems including oil, oil filter, tire rotation, air cleaner, automatic transmission fluid, rear differential fluid, spark plugs, timing belt and coolant. The system is designed to eliminate unnecessary maintenance, reduce environmental impact and expenses, and ensure long component and vehicle life.
SEQUENTIAL SPORTSHIFT 6-SPEED AUTOMATIC TRANSMISSION
To maximize driver control, acceleration and fuel economy, the ZDX is equipped with an all-new 6-speed automatic transmission featuring Sequential SportShift with racing-inspired steering wheel mounted paddle shifters and two automatic shift modes.
Though comparable in size and weight to Acura’s existing 5-speed automatic transmissions for V-6 engines, careful engineering of the layout and power flow minimizes size, parts count and overall weight.
The new Sequential SportShift 6-speed automatic advances launch-feel, acceleration performance and fuel efficiency. Compared to the 5-speed transmissions used with other V-6 engines in the Acura line, the ZDX has lower gear ratios (higher numerically) in First through Fifth gears and in Reverse. The lower gear ratios improve acceleration and pulling power. The new Sixth gear ratio is taller (lower numerically) than the top gear in Acura’s 5-speed V-6 automatic transmissions. The taller final gear allows for a relaxed cruising rpm and enhanced highway fuel economy.
The new 6-speed automatic transmission also includes engineering enhancements aimed at improved performance and economy. Expanded multi-disc lock-up control improves the efficiency of power delivery and works with the new gear ratios to provide a 1.0 mpg improvement in fuel economy on the highway, and a 0.8 mpg improvement in city driving, as compared to a conventional design.
The Sequential SportShift 6-speed transmission can be operated in two different fully automatic modes with the console-mounted straight-gate shifter. The D, or "Drive", mode is ideal for most driving situations, and combines fuel efficiency with smooth operation and responsive power when needed. The S, or "Sport", mode is for more performance-oriented driving, and features aggressive shift mapping to keep engine rpm higher for greater acceleration and response. In Sport mode the transmission typically operates in the four lowest gears, and won’t shift to Fifth gear unless the vehicle reaches very high speed. In Sport mode, the economy-oriented Sixth gear is locked out.
When in the D mode (that is optimized for normal driving), the transmission incorporates an advanced Grade Logic Control System, Shift Hold Control and Cornering G Shift Control-all of which reduce unwanted shifting and gear hunting. The result is smart transmission operation that optimizes fuel efficiency and keeps the transmission in the appropriate gear for the specific driving conditions, thus generating excellent performance and smooth operation.
While traveling up or down hills, Grade Logic Control alters the transmission’s shift schedule to reduce shift frequency and improve speed control. A shift map in the transmission computer continually measures throttle position, vehicle speed and acceleration/deceleration, and then determines when the vehicle is on a hill. The shift schedule is then adjusted to hold the transmission in lower gears to boost climbing power or to provide engine braking when traveling downhill.
Shift Hold Control keeps the transmission in its current (lower) gear ratio when aggressive driving is detected, as in the case of decelerating at a corner entry. Shift Hold Control leaves the chassis undisturbed by excess shifting and ensures that power will be immediately available (without a downshift) at the corner exit.
Cornering G Shift Control is a new transmission feature that debuts on the ZDX’s Sequential SportShift 6-speed. Cornering G Shift Control monitors the speed of each rear wheel independently to determine when the ZDX is turning. When the system detects a sufficient speed differential between the rear wheels, it will suppress an unwanted upshift. This prevents the transmission from upshifting during a corner, which could upset the chassis balance and would then require downshifting again at the corner exit when the throttle is applied.
Temporary Manual Operation in "Drive"
Whether in Drive or Sport mode, "smart" transmission logic programming allows the use of the steering-wheel-mounted paddle shifters. When the driver operates the steering wheel-mounted paddle shifters while in Drive, the transmission responds to the driver’s shift command and then returns to its normal fully automatic Drive mode if further paddle shift inputs are not made within a short time. This smart logic makes it easy for the driver to command a quick downshift without leaving the comfort of Drive mode. When in Sport mode, use of the paddle shifters puts the transmission into full manual mode that remains until another mode of operation is selected with the console-mounted shifter.
By moving the center console-mounted gear selector lever rearward to the detent labeled "S," the transmission is shifted into Sport mode. This mode offers automatic operation with aggressive shift mapping. A pull on the racing-inspired paddle shifters (mounted on the steering wheel) places the transmission in fully manual mode. A digital display in the tachometer face indicates which gear the transmission is in. A new double-kick-down feature lets the driver command a double downshift-such as from Fifth or Fourth gears. By pulling on the left downshift paddle twice in rapid succession, the transmission will drop directly to the chosen lower gear ratio. The Drive-by-Wire™ throttle system also creates a "blip" of the throttle to help match gear speeds while downshifting.
To prevent harm to the powertrain when the transmission is paddle shifted by the driver (including during double-kick-down shifts), the system will inhibit potentially damaging shifts. The Powertrain Control Module (PCM) can also cut off engine fuel flow to prevent over-revving.
If fuel cutoff alone is insufficient to prevent engine over-revving, as may be possible when the vehicle is on a steep downhill, the transmission will automatically upshift to prevent damage. On downshifts, the transmission will not execute a driver command that will over-rev the engine. For improved stop-and-go performance and to prevent "lugging" the engine, the Sequential SportShift transmission will automatically downshift to First gear even though the transmission has been left in a higher gear, (except in Second gear) as the vehicle comes to a stop. When coming to a stop in Second gear, the vehicle will start in Second gear as well.
MULTI-CLUTCH LOCK-UP TORQUE CONVERTER
The all-new 6-speed automatic transmission teams with a brand new torque converter that not only has a higher maximum torque rating, but also has a new converter lock-up assembly. The lock-up assembly uses multiple lock-up disks that generate nearly double the facing area of a typical torque converter. The new lock-up assembly not only reduces heat build-up during operation, but also features improved overall lubrication that generates better cooling. The new torque converter allows for lock-up activation during a much wider range of driving conditions, which, in turn, generates improved fuel economy.
STRAIGHT-GATE SHIFTER ASSEMBLY
The straight-gate shifter, located in the center console, is an intuitive and easy-to-use design that takes up little space in the center console. The shifter allows the driver to choose D (using First through Sixth gears) or S, which activates the performance-oriented Sport mode, which has more aggressive shift programming and locks out the use of Sixth gear when operating automatically. When in Sport mode, gear selection via racing-inspired paddle shifters mounted on the steering wheel automatically puts the transmission into manual mode, and the driver can select among all six transmission gear ratios.
COOPERATION BETWEEN TRANSMISSION AND DRIVE-BY-WIRE™ THROTTLE SYSTEM
Shift speed and smoothness are enhanced as a result of cooperation between the Drive-by-Wire™ throttle system and the electronically controlled Sequential SportShift 6-speed transmission. During upshifts and downshifts, the engine can be throttled by the engine management system, reducing peak forces (shift shock) on transmission components, thus improving component reliability and decreasing driveline harshness.
SUPER HANDLING ALL-WHEEL DRIVE™ (SH-AWD®)
The ZDX features Acura’s acclaimed Super Handling All-Wheel Drive™ (SH-AWD®), which progressively distributes optimum torque not only between the front and rear axles but also between the left and right rear wheels. The benefits of the SH-AWD® system are superior all-weather traction and neutral, accurate steering under power that is unmatched by front-drive, rear-drive or conventional all-wheel-drive systems. The 2010 ZDX SH-AWD® system is similar to the systems used in the RDX and MDX SUVs as well as the TL SH-AWD® performance luxury sedan.
By rotating the outside rear wheel faster than the front axle speed while cornering, SH-AWD® torque vectoring creates a yaw moment to help turn the vehicle through the corner-thus reducing understeer and improving handling balance and controllability. With cornering forces more evenly distributed between front and rear tires, overall cornering power is increased- regardless if driving on wet or dry roads.
Vehicles with high power ratings using conventional front or rear drive systems often use a limited-slip differential to help maintain traction when under power. By linking inside and outside drive wheels, these systems tend to resist turning and can increase understeer. Conventional AWD systems similarly work to link the inboard and outboard tires and the front and rear axles, which can create resistance to turning. Using torque vectoring to help turn the vehicle, SH-AWD® creates a more responsive, neutral and predictable platform while retaining the usual benefits of all-wheel drive.
Electronic Controls and Parameters
The SH-AWD system works is cooperation with the ZDX’s Vehicle Stability Assist (VSA) system to optimize torque distribution for superior handling and traction. The Powertrain Control Module (PCM) provides information on engine rpm, airflow and transmission gear-ratio selection, while the VSA® ECU provides wheel-speed data. The SH-AWD® ECU also monitors steering angle, lateral G-forces, vehicle yaw rate and electromagnetic clutch engagement for the right and left rear axle shafts. Drive torque is calculated from PCM information, and then the acceleration situation, wheel spin, lateral G forces and steering angle are used to determine the front-to-rear torque distribution and the torque split between right and left rear wheels.
SH-AWD® System Layout
The ZDX SH-AWD® is a full-time all-wheel-drive system that requires no driver interaction or monitoring, thanks to a torque-transfer unit that is bolted directly to the front-mounted transaxle. The torque-transfer unit receives torque from a helical gear that is attached to the front differential’s ring gear, and a short horizontal shaft and hypoid gear set within the torque-transfer unit’s case send power to the rear propeller shaft, which in turn transfers power to the rear drive unit.
The ZDX SH-AWD® rear drive unit is constantly overdriven by 1.7-percent and the resulting overdrive effect is regulated by left- and right-side electromagnetic clutch packs within the rear differential that independently control the power delivered to each rear wheel.
Direct Electromagnetic Clutch Systems
Direct electromagnetic clutch systems mounted on either side of the hypoid gear that drives the rear axle control the amount of torque sent to each rear wheel and provide a limited-slip differential function when needed. The clutches can be controlled as a pair to alter front/rear torque split or they can be controlled independently to allow 100-percent of rear axle torque to go to just one rear wheel.
An electromagnetic coil modulates the pressure controlling each clutch pack, which changes the speed of the sun gear within the rear differential’s planetary gear set to control the torque sent to each wheel. Electromagnetic control of the clutches permits torque delivery to each rear wheel to be proportioned in an exceptionally quick and precise manner, which reduces wheel-slip in low-traction conditions.
The clutch packs and their friction material are carefully designed to withstand the small amount of continuous slip between front and rear axles created by the 1.7-percent speed differential-all while delivering the durability expected of an Acura product. Through an oil-temperature sensor, the SH-AWD® Control Unit monitors the rear differential’s clutch-plate coefficient of friction (which changes with temperature) in each clutch pack and then adjusts the voltage to each electromagnetic coil to compensate. As total vehicle miles accumulate, the SH-AWD® Control Unit uses data from a feedback loop to adjust the voltage supplied to the electromagnetic coils to compensate for any clutch wear, ensuring optimal and consistent transmission of torque.
From the beginning of the ZDX concept, Acura designers committed to meeting and surpassing the vehicle dynamics and driving feel of its primary competitors- the BMW X6 and Infiniti FX35. The essential engineering targets included steering, suspension, braking and overall dynamic performance. In addition, superior control of noise, vibration and harshness (NVH) was paramount, as was the choice of Comfort and Sport modes made possible by an available Integrated Dynamics System (IDS).
To achieve a combination of ride comfort and a fun-to-drive character in all weather conditions, Acura used the famed Nürburgring Nördschleife circuit in Germany as an essential development tool. This 12.9-mile course contains more than 170 corners and is considered the toughest natural road course in the world. Engineers used the Nürburgring as a "weakness finder" because it clearly exposes problems with a vehicle’s dynamics, making them easier to identify and fix. Engineers took the ZDX to the Nürburgring on two separate occasions-once during pre-prototype testing to develop what would become the production suspension systems, and a second time with a prototype.
With its standard 19x8.5-inch wheels and available Active Damper System, the ZDX offers an excellent blend of all-season handling capability. Focusing on a passionate European driving experience, while also providing sophisticated control of NVH, the ZDX is a supremely comfortable long-distance machine and an exhilarating partner on back roads.
The overall dynamic target for the Acura ZDX was to provide sports sedan-like ride and handling without compromising ground clearance and all-weather handling performance. Built for driving passion, the ZDX achieves these three goals:
- Enjoyable and comfortable overall driving experience
- Exciting on-road, track-quality handling for driving enthusiasts
- Off-highway capabilities
For general driving conditions, Acura targeted a smooth ride with extremely accurate vehicle control-all while limiting NVH. In addition, the available Integrated Dynamics System (IDS), which includes Active Damping System (ADS), allows drivers to switch between Comfort and Sport modes, expanding the personality of the ZDX. The range between the two settings is significantly wider compared to the damper systems offered on the BMW X6 and Infiniti FX35. In addition, for the first time in Acura history, steering performance is linked to ADS to better suit the driver’s wishes.
Two typical scenarios where the Active Damper System suspension will shine:
- Cruising up the coast in the Comfort mode provides a comfortable, controlled and non-fatiguing driving experience
- Driving on a mountain road in the Sport mode delivers more precise, exceptionally responsive handling and steering
The ZDX’s entire front chassis was tuned to provide the best balance of handling precision, road isolation and impact aftershake damping. MacPherson struts team with coil-over springs and lower control arms constructed of forged aluminum to reduce unsprung weight. The front subframe "floats" on rubber mounts to provide road and engine isolation, and the subframe assembly is affixed to the main body structure with heavy-duty braces. The front suspension also uses hydro-compliance bushings to provide superior ride isolation as well as chassis vibration control. Suspension and engine mounts are specifically tuned to provide minimum vibration transfer to the occupants, and the front struts employ internal rebound springs to improve ride and handling. Anti-dive properties were specially tuned to reduce impact harshness and improve ride comfort.
The ZDX’s rear suspension is a multi-link design mounted on a separate steel subframe. Cast aluminum uprights reduce unsprung weight, while precise trailing-arm mounting points reduce body squat during hard acceleration. Progressive rate coil springs, dampers and an anti-roll bar are tuned for the optimum combination of ride and handling. Rear subframe mounts and lateral control link bushing rates create a discrete level of lateral force steer at the rear axle. Since the SH-AWD™ system constantly varies drive torque at the rear axle, the longitudinal and lateral force steer properties were carefully developed for optimum response, stability and consistency.
ACTIVE DAMPER SYSTEM
Many luxury vehicles offer some type of body motion control system using air suspension, electronically controlled dampers or automatically adjustable stabilizer bars. Acura considered all of the available technologies before choosing electronically-controlled Magneto-Rheological fluid dampers as the ideal technology to maximize ride comfort and handling- all in one integrated system. Included within the available Advance Package, the Active Damper System gives the 2010 ZDX an elevated level of handling precision designed to satisfy the most discriminating drivers, while maintaining a smooth and controlled ride.
The overall goal of the Active Damper System is to achieve an outstanding level of handling response while maintaining a refined level of ride comfort. This allows the driver intuitive vehicle control in a relaxed environment- free from a jarring ride, neck straining head toss and other sudden vehicle motions. This is made possible by the quick response of the dampers as controlled by computer algorithms that keep the dampers a step ahead of actual body movements. Advantages of the Active Damper System include:
- Flat cornering feel with a reduced body roll- even during spirited driving
- Responsive, precise and secure steering feel
- Elimination of unwanted under-damped body heave, roll and pitch motions
- Improved tire adhesion, vehicle stability and road isolation
Real-Time Damper Control
The secret to the ZDX’s Active Damper System is its fast-acting "semi active" shock absorbers. These dampers are built and tuned specifically for the ZDX and offer the ability to individually adjust from minimum to maximum damping force in as little as five milliseconds (0.005 sec.). Their ability to significantly change damping rate hinges on the principle of electromagnetic induction. Each damper carries a field coil-a collar containing many windings of magnetic wire-that generates an electromagnetic field when current is passed through it. Special damper fluid contains microscopic (about 10 microns in diameter) ferric spheres that align when surrounded by the electromagnetic field, dramatically and instantly changing the effective fluid viscosity. Not only is the overall range of damping force available significantly more than that of a conventional damper, but also there are literally hundreds of small steps available within that range.
An electronic control unit (ECU) determines the amount of electrical current that passes through the field coils via special algorithms which determine the best setting for the road conditions. The continually variable oil viscosity, combined with nearly instantaneous reaction time of the dampers, allows damping control to occur before the ZDX’s tires or body experience any extraneous motion.
The Active Damper System will deliver low damping when the road is smooth and the vehicle is being driven at a constant speed. Less damping reduces the amount of vibration and harshness that passes from the suspension to the body, quieting and improving the overall vehicle ride quality.
Using the dampers’ 5-millisecond response time, the Active Damper System reacts to sudden changes in driver or road inputs. A high damping force achieved in this short time allows the dampers to quickly aid the coil springs and stabilizer bars in roll and pitch control, greatly improving the handling of the ZDX.
The result of the improved transient handling, road isolation and body control afforded by the ZDX’s Active Damper System is a noticeable reduction in the driver’s workload. In short, the system is able to achieve the benefits of a sport-tuned suspension without the traditional ride comfort trade-off. The overall benefit is more enjoyment, better control and less fatigue over the long haul.
The computer algorithms that control the Active Damper System were specially created for the 2010 ZDX and offer a substantial difference between Comfort and Sport modes. Thus, drivers whose primary interest is comfort will be coddled over most road conditions, while those interested in a sport-driving experience will find the ZDX ready to tackle challenging roads.
The Active Damper System does not require any special maintenance, has no scheduled replacement interval and maintains the same quality, durability and performance as all other Acura components.
Integrated Dynamics System (IDS)
Controlled by Acura’s Integrated Dynamics System (IDS), the ZDX’s Active Damper System provides two driver-selectable settings-Comfort and Sport-that tailor both the suspension damper and speed-sensitive steering systems together for a more comfortable or more sporting ride.
Comfort mode allows for a more relaxed driving experience by prioritizing road isolation and reduced passenger fatigue caused by road inputs, while Sport mode prioritizes handling response, vehicle body control and tire adhesion to allow for spirited driving with high levels of precision and composure. Either Comfort or Sport mode can be used in any type of operating conditions as preferred by the driver.
The Integrated Dynamic System (IDS) computer algorithms that control the Active Damper System and speed sensitive steering were specially created for the new ZDX and offer a substantial difference between Comfort and Sport modes. Thus, drivers whose primary interest is comfort will be coddled over all kinds of road conditions, while those interested in a sport-driving experience will find the ZDX ready to tackle the most challenging roads.
The Active Damper System does not require any special maintenance, has no scheduled replacement interval and maintains the same quality, durability and performance as all other Acura components.
POWER RACK & PINION STEERING
For the first time in the Acura Division, the 2010 ZDX connects electronically controlled hydraulic power steering with the Active Damper System to provide an even more satisfying driving experience. The speed-sensitive hydraulic steering assist is automatically adjusted according to the driver’s choice of Comfort or Sport modes: Lighter steering wheel effort is generated in the Comfort mode, while firmer effort results when in Sport. Along with the active dampers themselves, the system gives the ZDX a complete package to provide consummate luxury or track-quality handling-purely at the driver’s discretion.
Acura engineers spent considerable time studying steering center feel in an effort to elevate the quality of steering feedback that the driver receives. Beyond offering the correct level of steering effort, the ZDX provides linear steering feedback that is an integral part of its subjective handling quality.
WHEELS AND TIRES
The 2010 ZDX has standard 19x8.5-inch 7-spoke aluminum wheels finished in luxurious silver with a bright-machined face and a chromed Acura center cap. Standard are Michelin Latitude P255/50R19 103H high-performance all-season tires that were specially developed for the ZDX by Michelin engineers. The tires offer outstanding traction in dry and wet conditions, while maintaining highly useful level of snow/ice traction as well. Of particular interest, the ZDX’s tires deliver a substantial improvement in wet and dry handling as well as a 5-percent reduction in rolling resistance-thus helping to improve fuel economy.
For the first time in Acura history, 20x9-inch accessory wheels and tires are available on the ZDX.
In the event of flat tire, a 17x4-inch wheel with T165/80D17 tire is mounted underneath the rear of the ZDX. Acura designed the spare-tire storage area to accept either a temporary or a full-size wheel, allowing the ZDX owner to carry a damaged full-size wheel and tire beneath the vehicle instead of in the cargo area.
4-WHEEL DISC BRAKES
The 4-wheel disc brakes on the 2010 ZDX are the largest brake system ever featured on a production Acura vehicle, an honor shared with the new 2010 MDX. The brake system is engineered to provide best-in-class braking capability in dry conditions, as well as while driving in rain, snow or icy conditions.
Engineers benchmarked the Acura ZDX against top competitors including the Porsche Cayenne and BMW X5/X6 for braking performance and overall pedal feel. As a result, the ZDX has minimal pedal travel and a firm pedal feel, in keeping with the sport-minded direct feel that enthusiast drivers want. The ventilated front rotors measure 13.0-inches in diameter with a thickness of 1.1 inches, while the rear rotors are a 13.1-inch diameter solid design with a thickness of 0.43 inch. The front brake calipers are dual-piston design while single-piston calipers are used in the rear.
The ZDX also has an anti-lock braking system (ABS) with Brake Assist, Hill Start Assist and electronic brake distribution as standard equipment, and a Collision Mitigating Braking System™ (CMBS™) is available.
VEHICLE STABILITY ASSIST™ (VSA®) WITH TRACTION CONTROL
Vehicle Stability Assist™ (VSA®) is included as standard equipment on the ZDX. By continually monitoring the vehicle’s operating parameters (such as road speed, throttle position, steering wheel position, accelerating/braking/cornering loads), VSA® detects if the vehicle is experiencing oversteer or understeer. To help correct either of these situations, VSA® automatically cuts the throttle to reduce engine power output as needed, and applies one or more brakes individually to help stabilize the chassis.
The VSA® response is so quick that the instability may be corrected even before the driver knows it’s occurring. Traction Control is integrated into VSA® and helps the ZDX accelerate smoothly on low traction surfaces. As stated in the SH-AWD™ section, VSA® works with SH-AWD™ to adjust engine torque distribution- thus allowing Direct Yaw Control of the ZDX to maximize stability under all driving conditions.
TIRE PRESSURE MONITORING SYSTEM (TPMS)
An onboard Tire Pressure Monitoring System (TPMS) warns the driver if the air pressure decreases significantly in any tire. The system helps reduce the chance of damaging a tire or losing control of the vehicle due to low air pressure. This is important because a slow leak, such as one that might be caused by a nail or road debris, might not be easily detectable-but over time could cause significant air loss, reduction of grip and potentially a blowout.
TPMS uses a sensor mounted on each wheel that continually monitors tire pressure and sends a coded signal to the TPMS electronic control unit (ECU). The process begins with a signal initiator located inboard of each tire on the chassis that sends a unique signal for each TPMS sensor. The TPMS sensor then sends tire pressure data to the TPMS ECU, which compares the values for each tire’s pressure against an acceptable range of pressures.
When a tire’s pressure drops significantly below the proper level, a "CHECK TIRE PRESSURE" alert will appear on the Multi-Information Display (MID) screen. The TPMS system can display the air pressure in all four tires simultaneously via the MID, making it simple to locate a specific low-pressure tire. If there is a fault in the system, a "CHECK TPMS SYSTEM" alert appears.
At the driver’s preference, the Multi-Information Display can continually show the air pressure in all four tires. Regardless of whether the driver chooses to monitor the pressures, a warning will still occur if a tire drops a specified level.
Although the ZDX is not designed as a hardcore "go-anywhere" off-road vehicle, it is engineered to be capable and competent whether traveling just off the pavement or off the beaten path. Engineers mandated specific minimum performance criteria for the new ZDX, including safe travel through standing water nearly eight inches deep, steep approach and departure angles (19.8-degrees front and 23.2-degrees rear, respectively, with a 16.9-degree break-over angle), off road and paved grades up to 60-percent incline. Moreover, components located underneath the ZDX are tucked away to help avoid damage during off-highway driving, a steel guard protects the fuel system’s evaporative canister and there is a generous 8 inches of clearance.
The high-torque 3.7-liter V-6 engine and SH-AWD™ system with Grade Logic and computer-controlled traction capabilities all help the ZDX meet most off-road challenges without the need for a dedicated low-range transfer case or a driver-selected 4WD "lock" mode. Generous front approach, break-over and rear departure angles also help the ZDX meet the various needs of its target buyers.
SNOW AND ICE CAPABILITY
The same technologies that make the ZDX capable off-road also enhance its performance in snow and ice. The SH-AWD™ system with Grade Logic Control and computer-controlled traction monitoring capabilities work together with the all-season tires to maximize power delivered to the road surface and thus driver control, in winter driving conditions.
NOISE, VIBRATION & HARSHNESS (NVH)
Elimination of undesirable wind or road noise, vibration and harshness (NVH) in the passenger cabin was among the highest and most essential priorities that engineers attacked for the 2010 ZDX. Acura began by focusing on vibration in the body during the engineering phase instead of simply adding materials to the body to damp it out later. Two examples of this process are the rear suspension mounting points, which have robust attachments to the unit-body for greater rigidity and reduced vibration, and stiff front and rear subframes, which allow the mounting bushings to be made softer.
Engineers paid strict attention to addressing two specific issues-concrete road noise and drumming-neither of which are acceptable to luxury customers. Thus, melt sheets are used in critical areas on the front bulkhead and floor, and light insulators are used on the bodysides, doors and roof. A hybrid carpet and padding system further reduces noise intrusion.
In addition to building a stiff unit body structure, Acura engineers installed three different types of body separators located in the A-, B- and C-pillars. These special separators close off the traditional hollow areas within the separator structures to help ensure that noise does not travel from the road into the passenger cabin. While other Acura vehicles also use pillar separators, the ZDX has the highest use of any Acura vehicle.
Additional sound-controlling mechanisms found in the ZDX include an acoustic glass windshield, 5mm thick side glass (compared to 3.5mm glass used by most manufacturers), 7-layer acoustic floor under covers (including the first Acura use of a rear-wheel inner fender insulator), front and rear sub-frame stiffeners, textile-covered inner fender liners and Active Noise Cancellation (ANC). In particular, the acoustic floor undercovers are especially effective.
With a towing capacity of 1,500 pounds, the 2010 ZDX can tow items such as a personal watercraft, motorcycles or a camping/utility trailer. A Towing Package is available as dealer-installed accessory, and includes a Class I hitch, receiver, ball and wiring harness.
For years, Acura vehicles have been successfully meeting ever more stringent world guidelines to reduce the content of harmful metals such as chromium and lead, along with reducing volatile organic compounds (VOC) and polyvinyl chlorides (PVC). The new 2010 ZDX marks the first Acura to use a mercury-free Navigation display screen, which features LED backlighting instead of traditional cold cathode backlighting. To reduce environmental impact at the factory, a special separation line isolates different manufacturing scrap materials, including aluminum, for recycling.

The 2010 ZDX continues Acura’s tradition of advancing passive safety feature content to achieve a high level of crash worthiness as well as top safety ratings in its class. The story begins with the Advanced Compatibility Engineering™ (ACE™) body structure, a technology designed to manage and disperse frontal collision forces to better protect the passenger cabin and improve car-to-car collision safety. Inside, standard passive-safety features include front seat belts with automatic tensioning system with load limiters, dual-stage, multiple-threshold airbags, front-seat side airbags, active front head restraints, knee bolsters for the driver and front passenger, and side curtain airbags for front and outboard rear passengers. The Acura ZDX with Advance Package also gets Acura’s innovative Collision Mitigating Braking System™ (CMBS™).
The ZDX meets the latest government safety regulations including FMVSS 214 (oblique pole) and is projected to achieve top-level test results in the National Highway Traffic Safety Administration (NHTSA*) front and side impact testing, as well as earning GOOD ratings from the Insurance Institute for Highway Safety (IIHS) in its Frontal Offset, Side Impact and Rear Crash Protection tests.
CRASH PERFORMANCE TARGETS
National Highway Traffic Safety Administration (NHTSA) tests include Frontal and Side impact testing, as well as Rollover testing, while Insurance Institute for Highway Safety (IIHS) tests include Frontal Offset, Side Impact (also known as SICE), and Rear Crash Protection indexes. Although official testing for the ZDX had not been conducted at press time, based on internal testing we anticipate the ZDX will receive 5-star ratings for the driver and front passenger in frontal impact testing, and 5-star ratings for front and rear seating positions in side impact testing. Similarly, Acura anticipates that the ZDX will receive "Good" ratings from the IIHS for frontal offset crash testing, side impact crash testing and rear crash protection.
As the popularity soared for light trucks (including pickups, crossover vehicles and SUVs) in the last decade, so did the risk of such large vehicles colliding head-on with smaller ones. In light of this risk, engineers of the 2010 Acura ZDX designed a front structure that helps minimize the likelihood of over-ride or submarining in frontal collisions between vehicles of disparate size.
The 2010 Acura ZDX makes pedestrian safety a high priority, and adopts several pedestrian-safety measures that U.S. law does not require. For example, the ZDX hood frame and aluminum hood panel are designed to help protect pedestrians by deforming over a broad area to absorb collision energy. In addition, the hood hinges are designed to bend and the windshield wiper pivots also feature a breakaway design to help reduce injury in the event that a collision with a pedestrian should occur.
Another target that Acura designers felt strongly about was the ZDX’s ability to withstand a rollover with the panoramic glass roof frame maintained, no fuel system damage, and no tailgate or tailgate door-opening damage. Though not required or regulated by the government, the high-strength steel safety cage provides the stiffness that allows the ZDX to better withstand rollover forces.
ADVANCED COMPATIBILITY ENGINEERING™ (ACE™)
Like every other Acura vehicle, the all-new 2010 ZDX features Advanced Compatibility Engineering™ (ACE™) unit-body design. ACE™ is an exclusive body design that enhances occupant protection and crash compatibility in frontal crashes. The ACE™ design utilizes a network of connected structural elements to distribute crash energy more evenly throughout the front of the vehicle. This enhanced frontal crash energy management helps to reduce the forces transferred to the passenger compartment and can help to more evenly disperse the forces transferred to other vehicles in a crash.
If the ZDX should collide head-on with a smaller and/or lighter vehicle, Advanced Compatibility Engineering™ also helps provide good engagement with the small vehicle’s frame. This helps reduce the risk of intrusion while simultaneously helping to disperse the crash energy across a wider area at the front of the vehicle.
IIHS SIDE IMPACT CRASHWORTHINESS EVALUATION (SICE)
The 2010 Acura ZDX was designed to achieve a "GOOD" rating in the rigorous IIHS Side Impact Crashworthiness Evaluation (SICE) evaluation, which measures how well a vehicle withstands intrusion from a large SUV in a side collision. The ZDX’s high-strength steel safety cage, along with the use of high-strength side door beams, help make it resistant to intrusion.
ACTIVE FRONT HEAD RESTRAINTS
The 2010 ZDX has active head restraints that help minimize the potential for the driver or front passenger to suffer a neck injury during a rear-end collision. During this type of collision, the occupant’s body applies pressure to the seatback. This pressure activates a lumbar plate that pushes the head restraint upward and forward to help equalize forces acting on the head, neck and spine during a collision. This ability to manage rear collision forces directly contributes to a reduction in the likelihood of whiplash injuries.
For rear-seat passengers, adjustable headrests can be manually raised 88mm (3.46 in.) from their nested position within the seatback for maximum comfort and support. When not in use, the rear headrests can be positioned flush with the seatback to improve rear visibility.
The IIHS Rear Crash Protection test measures the protection for front-seat occupants from whiplash or neck injury. Thanks to the active head restraints, the ZDX is projected to receive the highest "GOOD" rating for both driver and passenger.
FMVSS 214 OBLIQUE POLE
The revised FMVSS 214 test is especially challenging, as it models a scenario where a vehicle slides sideways into a pole or tree, which focuses a tremendous amount of collision energy in a small area of the vehicle. A new standard will soon be introduced beginning with the 2011 model year and will continue until all new cars in 2015 meet it. The 2010 ZDX already meets this upcoming standard now, ahead of the regulation phase-in schedule.
FMVSS 216 ROOF CRUSH
The 2010 ZDX was engineered to surpass the existing government roof crush test standard of 1.5 times the curb weight of the vehicle, and is anticipated to meet the upcoming standard of three times curb weight. Efficient use of high-strength steel creates a body structure with the stiffness to allow such results while still permitting the use of the double moonroof design.
STANDARD VEHICLE STABILITY ASSIST™ (VSA™) WITH TRACTION CONTROL AND BRAKE ASSIST
Standard equipment on the 2010 Acura ZDX is Vehicle Stability Assist™ (VSA™), an Electronic Stability Control system that enhances controllability while the vehicle is accelerating, braking or cornering, or when the driver makes a sudden maneuver. VSA™ has been retuned for 2010 to deliver a 10-percent improvement in performance during hard acceleration on slippery surfaces. The VSA™ works in conjunction with the vehicle’s drive-by-wire throttle and its 4-channel ABS system to help the vehicle maintain the driver’s intended path of travel. It functions by applying brake force to one or more wheels independently while also managing the throttle, ignition and fuel systems to reduce engine power output.
Vehicle Stability Assist™ constantly analyzes data from seven sensors that monitor wheel and vehicle speed, steering input, lateral G-forces and yaw rate, and compares the driver’s control inputs with the vehicle’s actual response. Whenever the vehicle’s actual response falls outside of a predetermined acceptable range, VSA™ intervenes with corrective action. If VSA™ detects an oversteer condition, the system may apply braking force to the outside front and rear wheels to counteract the unintended yawing effect. Or in the event of understeer, VSA™ may apply braking to the inside rear wheel while reducing engine power to help return the car to its intended course.
Vehicle Stability Assist™ is calibrated to work in a nearly transparent manner, meaning that drivers may not even be aware of its operation. Therefore, to keep the driver informed, an indicator light flashes on the instrument panel anytime the system is enhancing vehicle stability. While the driver may deactivate the VSA™ and traction-control functions via a switch on the instrument panel, ABS and Brake Assist remain fully operational at all times.
Brake Assist, which utilizes some of the VSA™ system components, recognizes emergency braking situations and assists the driver to apply maximum braking force to slow the vehicle more quickly. This important system is controlled by special computer logic that determines when the speed and stroke of the brake pedal exceed a typical range-as they would in a panic stop. At this point the modulator pump increases braking pressure to ensure maximum stopping force and help shorten braking distance as much as possible. Brake Assist functions only when the driver is pressing the brake pedal; the additional braking force provided by the system ceases when the driver releases pressure on the brake pedal.
ADVANCED 4-CHANNEL ABS WITH ELECTRONIC BRAKE DISTRIBUTION
The 2010 Acura ZDX is equipped with 4-wheel disc brakes and a sophisticated 4-channel/4-sensor anti-lock braking system. The system helps improve active safety by offering a firm brake-pedal feel and a short activation stroke, as well as Electronic Brake Distribution (EBD) circuitry that automatically proportions braking force between the front and rear wheels based on the vehicle’s weight distribution. EBD helps maximize braking effectiveness whether the ZDX is transporting only the driver, or is fully loaded with passengers and luggage.
DRIVER AND FRONT PASSENGER DUAL-STAGE, MULTIPLE-THRESHOLD AIRBAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
The ZDX is equipped with dual-stage, multiple-threshold front airbags (SRS).. One or both of these airbags will be deployed only in the event of a sufficient frontal impact. If deployed, these airbags are capable of being inflated at different rates depending on crash severity, seatbelt usage and other factors.. Frontal airbags are designed to supplement the seatbelts to help reduce the likelihood of head and upper body injuries in frontal crashes.
Dual-Stage, Multiple-Threshold Airbag Parameters
- Airbag deployment thresholds are controlled depending on the severity of a collision, driver seat position, passenger weight, and the buckle status of both occupants.
- The dual-stage, multiple-threshold strategy applies to front airbags only and does not affect operation of side airbags or side curtain airbags
The ZDX airbag system uses a sensor to assess the weight of the front passenger. The front passenger airbag is shut off if the weight sensor indicates that a small child is occupying the front seat. In addition, the driver’s seat has a seat position sensor: if the seat is in a more forward position (where the occupant will be close to the airbag), the airbag is fired with a longer delay to reduce the chance of injury caused by the airbag itself. A laser-cut, seamless instrument panel cover fully conceals the instrument panel-mounted passenger airbag while the driver-side front airbag is housed within the steering wheel.
DRIVER AND FRONT PASSENGER KNEE BOLSTERS
To help reduce the likelihood of injuries to the driver or front passenger’s legs in a frontal collision, the ZDX has energy-absorbing knee bolsters. The bolsters are designed to help dissipate collision forces if the driver or front passenger’s legs should contact the lower instrument panel during a frontal collision.
DRIVER AND FRONT PASSENGER SIDE AIRBAGS WITH FRONT PASSENGER OCCUPANT POSITION DETECTION SYSTEM (OPDS)
Side airbags mounted in the outboard area of each ZDX front seatback are designed to provide torso and pelvis protection in the event of a side impact. In addition, the front passenger’s seat is equipped with Occupant Position Detection System (OPDS), an innovative technology designed to deactivate the side airbag if a child or small-stature adult leans into the side airbag deployment path. When the passenger returns to an upright seating position, the side airbag reactivates so it can deploy to help protect the occupant in a side impact. The unique system utilizes sensors in the passenger seatback to determine the height and position of the occupant. The 2010 ZDX’s side airbags have a 2-chamber design featuring a stiffer lower chamber to load the pelvis area earlier in the collision, along with a softer upper chamber to help reduce the likelihood of a rib injury.
Side Curtain Airbags
In a severe side impact or rollover, the ZDX’s side curtain airbags deploy from roof-mounted modules, to help provide head protection for front and outboard rear occupants. Side curtain airbags effectively cover the side window area from the front to rear seats in both side and rollover impact collisions. Tests show that the g forces acting upon an outboard occupant’s head are far lower with side curtain airbags.
FRONT SEAT BELTS WITH AUTOMATIC TENSIONING SYSTEM
The ZDX front seat belts have an automatic tensioning system with load limiters to help protect the driver and front passenger in a collision. Research has shown that seat belts that are snugly secured around the occupants provide better protection; thus, in the first few milliseconds of a collision a tensioning system-powered by a small pyrotechnic device-automatically tightens the front seat belts. If deceleration forces rise above a predetermined threshold, a load limiter releases a small length of seat belt webbing to reduce the pressure applied to the occupant. The load limiter system helps reduce the injuries that seat belts can cause in a severe high-speed collision.
In addition, the driver’s seat belt has a dual-stage load limiter that provides a higher initial load, and then steps down to a lower load after a certain amount of the seat belt spools out. The dual-stage load limiter is specially designed to prevent too much forward driver movement, given the close proximity of the steering wheel.
All ZDX seating positions feature 3-point seat belts, and adjustable shoulder belt height is available for front seat passengers. The rear center seat belt buckle stores in a recessed pocket when not in use.
LATCH (LOWER ANCHORS AND TETHERS FOR CHILDREN)
The 2010 ZDX includes a LATCH (Lower Anchors and Tethers for CHildren) child-seat mounting system for the outboard rear seating positions. LATCH features built-in lower anchors and ready-to-use tether attachment points that allow compatible child safety seats to be installed without using the vehicle’s seat belt system. Additionally, the LATCH system simplifies child-seat installation when an owner installs a LATCH-compatible child seat. The center rear seat position has upper tether anchors only.
ACTIVE FRONT HEAD RESTRAINTS
The 2010 ZDX is fitted with active front head restraints designed to help minimize the risk of neck injuries in the event of a rear impact. The head restraint is mechanically linked to a lumbar plate located inside of the front seatback. In a rear impact, the occupant’s body pushes against the seatback, causing the head restraint to move forward in a carefully prescribed arc. This motion helps equalize the impact forces transmitted to the head, neck and spine as the occupant’s head moves backward during the collision. Effectively managing and dispersing this energy is critical to help minimize the potential for injuries.
TIRE PRESSURE MONITORING SYSTEM (TPMS)
Standard on the ZDX (and every other Acura model) is a Tire Pressure Monitoring System (TPMS) that alerts the driver whenever the air pressure in one or more of the tires decreases below a specified level. Using four sensors (one in each tire), TPMS transmits information on tire air pressure to the vehicle’s ECU. A low tire pressure indicator located on the instrument panel illuminates when tire pressure drops to a potentially critical level.
FUEL TANK SAFETY
The ZDX’s 21-gallon fuel tank is positioned in front of the rear body-deformation zone to help minimize the risk of damage in a collision. Locating the fuel tank in this protected area optimizes vehicle balance by moving the weight of the fuel tank farther forward. High-strength steel, which is used to help the ZDX meet the offset rear collision testing that is part of the federal FMVSS 301 fuel system integrity standard, is also used to help protect the fuel tank.
COLLISION MITIGATING BRAKING SYSTEM™ (CMBS™)
The ZDX Advance Package includes a Collision Mitigating Braking System™ (CMBS™), the first application of this technology on an Acura SUV. This revolutionary safety technology monitors the likelihood of a rear-end collision, and uses audio, visual and tactile signals to alert drivers to the risk of collision. Should the system determine that a collision likely is unavoidable, it applies the ZDX’s brakes and tensions the front seat belts to help reduce impact force on occupants. Unlike pre-collision systems on competitive vehicles, in certain circumstances CMBS™ automatically applies the brakes to help mitigate the severity of a collision.
Using a millimeter-wave radar unit located inside the front grille, the CMBS™ system monitors the distance between the ZDX and the vehicle directly in front of it up to a distance of 300 feet, and tracks the rate of closure between the two vehicles. If the closing rate increases to a point where a collision is likely to occur (based on relative vehicle speeds and following distance), the CMBS™ system uses visual and audible warnings to prompt the driver to take preventative action. Based on the driver’s response, the system will disengage if it determines that the likelihood of a collision has decreased to an acceptable level.
If the driver’s response does not sufficiently reduce the risk of a collision, the CMBS™ system will issue a secondary warning consisting of audible, visual and tactile elements as well as light braking to alert the driver to take action. If the closing rate increases so much that a collision becomes seemingly unavoidable, CMBS™ can initiate hard braking to reduce the vehicle’s speed as well as automatically tension the driver and front passenger seat belts to help reduce the severity of the crash. In some circumstance, CMBS will not give any or all warnings before applying the brakes.
The CMBS™ system used in the ZDX’s Advance Package is similar in concept to the one used on the Acura RL, and its special seat belt retractors replace the standard automatic tensioning system found on the base ZDX and the ZDX with Technology Package.
