The Acura TSX sports sedan was an all-new, clean sheet design for 2009. Improvements came in nearly every category including a bold new exterior design, added interior refinements as well as enhanced driving dynamics. The second generation TSX has been well received by both customers and the automotive press, garnering awards and breaking sales records. For 2010, the TSX receives major enhancements - including an available V-6 engine.
While the TSX with 2.4L I-4 engine produces spirited driving, TSX engineers want to push the performance envelope with an available V-6 package that delivers substantially more power and sportier handling coupled with larger wheels and tires. The new V-6 package further accentuates the TSX’s sporty driving character that has become an Acura trademark.
With two distinct powertrain choices for 2010, the TSX offers added appeal to buyers considering a new vehicle within the Entry Premium segment.
THE ENTRY PREMIUM MARKET
With a price point typically in the high $20,000 to low $30,000 range, the "entry premium" sedan segment represents the gateway to over a dozen automakers. Customers will find the Acura TSX positioned alongside the Audi A4, BMW 3-series, Infiniti G, Lexus IS and Mercedes -Benz C-class. With the entry to a luxury brand comes high expectations and the TSX - together with the award-winning Acura dealership experience - is ready to meet all of them. For 2010, the new TSX V-6 further raises the performance bar for those looking for even better acceleration and handling. While the TSX with 2.4L I-4 competes with vehicles such as the A4 2.0T, 328i, IS 250 and C300, the TSX V-6 targets even more performance minded entry luxury sedans. The TSX V-6 is a strong consideration for customers who will shop the Audi A4 3.2, BMW 335i, and Lexus IS 350.
The 2010 TSX is designed to appeal to young professionals who are previous TSX owners, conquests from other luxury brands such as Audi, BMW and Lexus , as well as to customers whose income and tastes are moving upscale. Demographically, TSX buyers are expected to range in age from 28 to 34 years old and hold a college degree. These customers are split nearly evenly between male and female, and slightly less than half are married. They are image seekers and will appreciate the styling, technical allure and total performance that the TSX offers - while also valuing the outstanding customer treatment that owners have come to enjoy at Acura dealerships.
The buyer for the new TSX V-6 is expected to be older (approximately 38 years old) than the TSX buyer, 80-percent male, 60-percent married, with a household income of about $110,000. Remaining the same is that the TSX V-6 buyer will be extremely brand conscious and eclectic in their tastes and interests. With the introduction of a V-6 powered TSX, Acura will fill a niche in its lineup between the four-cylinder TSX and the all-new TL performance luxury sedan. With the TL moving more upscale following its redesign in the 2009 model year, the TSX V-6 will be aimed squarely at youthful buyers who want a performance-oriented sports sedan in a more personal size.
ENGINE & POWERTRAIN
With the introduction of a V-6 powered TSX, Acura will fill a niche in its lineup between the four-cylinder TSX and the all-new TL performance luxury sedan.
Now available for the 2010 TSX is a new 3.5L SOHC V-6 that develops 280 horsepower and 254 lb-ft of torque. The V-6 features VTEC® valvetrain control, a high 11.2:1 compression ratio and a dual-stage induction system contained within a lightweight magnesium intake manifold. The V-6 has been tuned to deliver a linear torque curve with emphasis on the rpm range most commonly used for day-to-day driving. The new 3.5L V-6 meets California’s stringent CARB LEV II ULEV emissions certification and achieved an EPA estimated 18 mpg in city driving and 27 mpg on the highway**.
Sporty performance, fuel efficiency and low emissions are the hallmarks of the 2010 TSX’s all-aluminum DOHC i-VTEC® inline four-cylinder engine. Displacing 2.4 liters and producing 201 hp and 172 lb-ft of torque (6MT), the engine produces its useable power across a wide rpm range, while the broad torque curve further strengthens the engine’s pulling power at middle rpm levels. This allows the 2010 TSX to be responsive off the line, out of corners and when overtaking other vehicles.
The performance and flexibility of the 2.4L I-4 is credited to a high compression ratio, efficient valve timing, and a high flow intake and exhaust system. Further credit also goes to the TSX’s i-VTEC® "intelligent" valve control system. Variable Valve Timing and Lift Electronic Control (VTEC®) combines with Variable Timing Control™ (VTC™), to deliver top-of-class power. Likewise, a rear-mounted exhaust manifold layout, a close-coupled catalytic converter design and a Programmed Fuel Injection (PGM-FI) system substantially reduce emissions levels, enabling the 2010 TSX to meet the EPA TIER 2 - BIN 5 and CARB LEV II Ultra Low Emission Vehicle (ULEV) standards.
TSX customers who choose the spirited four-cylinder engine have a choice of two transmission styles as standard equipment - a 6-speed close-ratio manual or a Sequential SportShift 5-speed automatic. The manual transmission features a short-throw shifter with a precise, light action that makes it highly rewarding to use, and its aluminum case reduces vehicle mass to improve all-around performance and efficiency.
The new TSX V-6 features a sophisticated Sequential SportShift 5-speed automatic transmission that can be operated manually via steering wheel mounted racing inspired paddle shifters. The smooth shifting automatic is also fitted with intelligent features such as Grade Logic Control and Shift Hold Control, which make driving the TSX on hilly or winding roads more enjoyable.
BODY & CHASSIS
The 2010 TSX features a wide and muscular body which translates into outstanding handling and performance. The wide body (72.4 inches), long wheelbase (106.4 inches) and overall length (185.6 inches) give the TSX excellent ride quality and ample interior space for passengers. The high roll center helps reduce body roll during cornering for a more sporty driving experience.
The TSX uses Showa dual-mode suspension dampers, which provide superior suspension damping characteristics at both lower and higher damper speeds. The TSX employs Electric Power Steering (EPS) that delivers precise input during performance driving.
Advanced techniques in body design and construction, such as the use of cross-braced roof structure and a strong rear bulkhead, yield a very rigid and vibration-resistant structure. Aerodynamic tailoring included the use of inside frame rails, comprehensive aerodynamic tailoring underneath the car, and the use of A, B and C-pillar separators - all of which give the TSX a quiet cabin even over rough roads and at high speed. The TSX’s slippery aerodynamics also helps fuel economy as well as high-speed stability, all while lowering emissions.
Functionality and refinement, luxury and style converge in the interior of the 2010 Acura TSX . Featuring a blend of sweeping shapes, a high level of standard comfort and convenience features, widespread use of premium materials and an available Technology Package, the TSX sports sedan offers an upscale, modern interior that customers have come to expect from Acura.
First impressions are powerful, and an initial look inside the TSX reveals much about its character. From the precision crafted metal door sills to the satin-metal finish accents, from new leather-covered seats to the steering-wheel mounted controls, and from the premium 7-speaker sound system to the dual-zone automatic climate control, the TSX represents a merge of intelligent design and innovation. Bluetooth® connectivity is standard and includes HandsFreeLink® cellular telephone interface that makes communications easier while en route. The TSX’s Keen-Edge design blends perfectly with its range of electronic features in a way that makes the driving experience more satisfying.
Adding to the already impressive list of TSX standard equipment is the available Technology Package, which bristles with leading-edge electronics that make driving that much more efficient and enjoyable. The Acura Navigation System with Voice Recognition™, AcuraLink Real-Time Traffic™ and AcuraLink Real-Time Weather™, and the highly useful AcuraLink® Satellite Communication System are the centerpieces of the Technology Package. The navigation system features continuously updated traffic maps covering 77 major metropolitan markets, and offers Traffic Rerouting™ to help navigate around slow-downs. Also available is a 10-speaker premium sound system tuned by legendary recording engineer and producer Elliot Scheiner. The 10-speaker Acura/ELS Surround® Premium Audio System includes a Note function for XM® Radio that makes it easy to identify songs to recall at a later date. With push of a button, the Note feature can capture 10 seconds each of up to 30 songs, along with text indicating song title, artist name, and XM® channel.
Providing an array of advanced safety features is among the highest priorities of the 2010 Acura TSX. Leading the way is the TSX’s new Advanced Compatibility Engineering™ (ACE™) body structure. ACE™ improves the dispersal of frontal crash energy via load-bearing frame structures that better match the TSX with other vehicles of different sizes and with different bumper heights. Simply put, ACE™ maximizes the effectiveness of the TSX’s front crumple zones, better dispersing crash forces before they reach the passenger compartment.
Contributing to the safety performance of the 2010 TSX is a broad range of passive safety features, including six airbags (dual-stage, dual-threshold front airbags, new dual-chamber front seat side airbags, and side curtain airbags for outboard seating positions). Three-point seatbelts and head restraints are provided in all seating positions, and the TSX driver and front passenger are further protected by front seatbelt load limiters with an integrated automatic tensioning system, plus active front head restraints. The rear seat features a Lower Anchors and Tethers for CHildren (LATCH) system that allows for the secure and quick affixing of up to two child seats.
Exterior features designed to further improve safety include daytime running lights (DRL), pedestrian injury mitigation technologies such as a deformable hood panel, hood hinges, and windshield-wiper pivots.
The 2010 Acura TSX achieves the highest ratings in both government (NHTSA*) and independent (IIHS) crash testing - including IIHS’s TOP SAFETY PICK.
The most significant change to the TSX for 2010 is the availability of an all-new V-6 engine.
For the first time, the TSX will be available with a transversely mounted 3.5-liter all-aluminum V-6 engine with single overhead camshaft (SOHC) cylinder heads. The 12 intake valves are actuated by Acura’s acclaimed VTEC® (Variable Valve Timing and Lift Electronic Control) system. The compact and efficient V-6 engine produces 280 horsepower and 254 lbs-ft of torque. The power curve has been specially tailored to deliver strong, linear power in the rpm range used in most day-to-day driving conditions.
For 2010, the 2.4-liter DOHC i-VTEC® inline four-cylinder engine remains as the standard engine. The engine offers good acceleration while generating excellent fuel efficiency. The advanced, all-aluminum I-4 engine produces 201 hp and 172 pound-feet of torque (6MT), and incorporates Acura’s i-VTEC® "intelligent" valve control system that features Variable Valve Timing and Lift Electronic Control (VTEC®) combined with Variable Timing Control™ (VTC™). Though peak horsepower is virtually unchanged versus the previous generation 2.4L engine, peak torque output has risen by 8 lb-ft. In addition, the engine’s torque curve has fattened considerably. Horsepower, for example, is up five percent at 4,400 rpm. The result is stronger throttle response and better acceleration just about everywhere in the engine’s operating range. To achieve these power gains, the engine has a higher compression ratio, new valve timing, and intake and exhaust flow improvements. An aluminum and resin composite intake manifold reduces weight over the previous I-4’s aluminum design, while better insulating the engine’s incoming airflow from under-hood heat.
A rear-mounted exhaust system layout, close-coupled catalytic converter and advanced Programmed Fuel Injection (PGM-FI) team to help both the 4-cylinder and V-6 engines meet EPA 2 - Bin 5 and CARB LEV II Ultra Low Emission Vehicle standards.
The 2010 TSX with 2.4L I-4 engine comes with a choice of two transmissions – a standard 6-speed close-ratio manual transmission or a Sequential SportShift 5-speed automatic transmission. The manual gearbox has a lightweight aluminum alloy case and multi-cone synchronizers providing a light, quick action with very short shift throws. To provide more spirited driving, the manual transmission includes performance-minded gear ratios to maximize acceleration during spirited driving.
The Sequential SportShift 5-speed automatic has a straight-style shift gate with Drive and Sport positions that provide fully automatic operation. At the driver’s option, the automatic transmission can be shifted manually via steering wheel mounted paddle shifters. Grade Logic and Shift Hold Control work in automatic mode to keep the transmission in the gear that’s ideal for the driving situation. Further improving performance and drivability is a revised torque converter lock-up assembly.
100,000-mile tune-up intervals and a standard Maintenance Minder™ system, which automatically monitors the vehicle’s unique operation condition to indicate to the driver when maintenance is required, help to lessen the cost of ownership. The Maintenance Minder™ system is designed to ensure that important service issues are addressed in a timely manner, and eliminate unnecessary maintenance procedures to help reduce environmental impact and operating expenses.

The TSX’s 3.5-liter V-6 engine uses an inherently smooth-running 60-degree V-angle. The engine block is constructed of lightweight die-cast aluminum and uses thin-wall iron liners that are made in a centrifugal spin-casting process that ensures high strength and low porosity. The rough outer surface of these liners makes an effective bond with the aluminum block, enhancing block stiffness and heat transfer from the cylinder liners to the block.
The 3.5-liter cylinder block is heat-treated for strength and has deep-skirt designs with four bolts per bearing cap (providing excellent structural support for the crankshaft), thus minimizing engine noise and vibration.
The 2.4L I-4 uses a die-cast lightweight aluminum cylinder block with cast-in iron cylinder liners that are made using a unique spin casting, centrifugal process. For maximum rigidity and minimal noise and vibration, the cylinder block is a 2-piece design that supports the five main bearings with a single cast-alloy bed-plate assembly.
The 3.5-liter engine employs a robust forged-steel crankshaft for high strength and minimum weight. Forged aluminum 11.2:1 pistons are used and are cooled with oil spray directed up to the underside of the piston crowns, making possible the high compression ratio. The connecting rods are steel forgings for high strength, and are “crack separated,” a unique process in which the bearing caps are broken apart from the rod rather than machined separately. This process forms a lighter, stronger connecting rod with perfect mating surfaces.
The four-cylinder uses a high strength forged-steel crankshaft with micropolished journals to help reduce friction and to improve long-term durability. High compression 11:1 alloy pistons use special low-friction rings to reduce power loss.
CYLINDER HEAD / VALVETRAIN
The 3.5-liter engine has lightweight aluminum cylinder heads that are pressure cast for high accuracy and low porosity. To save weight and reduce parts count, these cylinder heads have uniquely integrated exhaust-port castings that provide optimal positioning for close-coupled catalytic converters- one on each cylinder bank. This design results in more rapid “light off” of the catalytic converters for reduced emissions during cold start-up. The cylinder heads are sealed to the block with a special 3-layer shim-type head gasket.
The 2.4L I-4 cylinder head is constructed of pressure-cast aluminum alloy and features four valves per cylinder actuated by dual overhead camshafts (DOHC). The cams are driven by an automatically adjusted silent-type chain. The chain system is maintenance free and runs in an oil bath for maximum durability. The combustion chambers have large "quench" areas to promote faster flame propagation and more complete burning, thus helping to reduce carbon monoxide (CO) and hydrocarbon (HC) exhaust emissions. Large intake and exhaust valves along with high-flow ports contribute to excellent engine breathing. Additionally, a high compression ratio of 11.0:1 is a significant contributor to the TSX’s torque output.
VTEC® VALVE CONTROL SYSTEM
The 3.5-liter V-6 engine uses the Variable Valve Timing and Lift Electronic Control (VTEC®) system that provides 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 valve lift and longer duration at higher speeds for optimum power. With the VTEC® system, both intake valves are controlled by a single low-speed camshaft lobe.
On the V-6, at 4,750 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, these pistons lock together each cylinder’s intake rocker arms, which then follow in unison a single high-lift, long-duration cam lobe. Intake valve lift and opening duration are adjusted according to engine speed, resulting in a broad torque curve as well as superior power at peak rpm.
The 2.4L I-4 engine features Acura’s i-VTEC® "intelligent" valve control system. Featuring Variable Valve Timing and Lift Electronic Control (VTEC®) combined with Variable Timing Control™ (VTC™). A patented VTEC® design uses three reduced-thickness aluminum rocker arms that operate a pair of valves for each cylinder. At low rpm, the intake valves follow low-lift, short duration camshaft profiles to help boost low-end torque. Above 5,000 rpm, the valves are operated by high-lift, long-duration camshaft profiles for maximum high-rpm horsepower.
To further refine the I-4’s operation, the engine features an “intelligent” element that adds Variable Timing Control™ (VTC™) to VTEC® which provides continuously variable, computer controlled camshaft timing. In total, the I-4’s i-VTEC® system provides performance, efficiency and emissions benefits by allowing the intake valve lift and valve timing to be continuously adjusted to suit the engine’s operating parameters.
Variable Timing Control
With the 2.4-liter engine, intake camshaft timing is continuously adjusted to suit engine operating conditions via a system called Variable Timing Control™ (VTC™). An integral part of the i-VTEC® system, the VTC™ enhances power output, fuel economy and emissions performance with its precise control of cam timing.
Camshaft position, intake manifold pressure and engine rpm are simultaneously monitored by the powertrain control unit (PCM), which then commands a VTC™ actuator to advance or retard the intake camshaft timing. The intake camshaft is almost fully retarded at idle to deliver more stable idle and reduced hydrocarbon (HC) emissions. As engine RPM builds, the intake camshaft is progressively advanced so the intake valves open sooner and valve overlap increases. Such operation reduces pumping losses, which increases fuel economy and further reduces exhaust emissions due to the creation of an internal exhaust-gas recirculation effect.
The 3.5L V-6 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 valves are closed at low engine speed, which reduces the operating volume of the plenum and increases the effective length of the inlet passages. The result is maximum resonance effect and amplification of pressure waves within each half of the manifold at lower engine speeds, significantly increasing cylinder filling and 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.
At 3,950 rpm the butterfly valves open, connecting the two halves of the manifold, increasing its effective volume and increasing the mass of air rushing down each intake passage. The inertia of this increased air mass forces more charge into each cylinder for better cylinder filling, increasing power at high rpm. The manifold’s two modes further complement the changes in low and high speed running made possible by the VTEC® system.
The 2.4L I-4 induction system is designed for high flow as well as to create an aggressive sound. The inlet design allows cool ambient air to be picked up at the front of the vehicle, and then routed though a high-flow air filter assembly. The single-stage lightweight plastic intake manifold has fixed-length intake runners that are tuned in length, diameter and shape to provide an optimal blend of low-rpm torque and high-rpm response. The new manifold incorporates 48 mm intake runners along with a high flow aluminum throttle-body.
PROGRAMMED FUEL INJECTION (PGM-FI)
Programmed Fuel Injection (PGM-FI) uses an array of sensors to constantly monitor a number of critical operating variables, including throttle position, intake air temperature, water temperature, ambient air pressure (altitude), air flow, air/fuel ratio, along with the position of the crankshaft and camshafts. Highly vaporized-style fuel injectors reduce the typical size of fuel droplets, which improves air/fuel atomization and flame propagation inside the combustion chambers.
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 and higher horsepower.
DRIVE-BY-WIRE THROTTLE SYSTEM
In place of a conventional mechanical throttle linkage, the TSX uses a Drive-by-Wire™ throttle system. The result is more accurate and precise throttle control, along with reduced weight and less clutter under the hood. A DC motor controls the throttle-body butterfly position in the intake tract. This allows the ratio between pedal movement and throttle motion to be altered to suit the driving conditions. The system monitors throttle pedal position, throttle butterfly position, road speed, engine speed and engine vacuum. This information is used to define the throttle control sensitivity. The system also alters response based on the calculated road slope, providing more throttle gain uphill and less downhill, and also reduces changes in gain on curvy roads to make the car easier to control.
The Drive-by-Wire™ throttle system works with the Sequential SportShift 5-speed automatic transmission to make shifts smooth and quick. With coordination of the throttle opening and the transmission’s shifting functions, shift shock and delay are reduced.
ONE-TOUCH STARTER SYSTEM (TSX V-6)
A TSX fit with 3.5-liter V-6 features a starter with more power to crank the larger engine. In addition, the TSX V-6 has a one-touch starter system that automatically maintains starter engagement until the engine has started. The TSX driver simply activates the starter switch once by turning the key and needs not hold the switch in the Start position. Once the V-6 engine starts, the one-touch system disengages the starter automatically.
The TSX 3.5-liter V-6 has exhaust manifolds that are cast directly into the cylinder heads for reduced weight, parts count and bulk. Attached directly to the cylinder heads are high-efficiency 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, reducing emissions during 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 under-floor catalytic converter.
Downstream of the under-floor converter, the V-6 engine has a single pipe that feeds to a pair of resonators, followed by a pipe split that connect to a pair of high-flow mufflers fit with round exhaust tips. With the V-6, the exhaust system is tuned to deliver a sportier, more aggressive exhaust note than with the 2.4L I-4.
To help boost engine torque, the 2.4L I-4 has a high-flow, low back-pressure exhaust system. Large-diameter pipe sizes throughout the exhaust system increase flow; beyond the under-floor catalytic converter, the exhaust system passes through a pre-chamber under the second-row floor, and then splits just behind the rear axle to feed into free-flowing dual silencers and chrome exhaust tips.
The 2010 TSX is compliant with the California Air Resources Board (CARB) LEV II ULEV standard, which is one of the toughest emissions regulations in the United States. The TSX also achieves EPA TIER 2 - BIN 5 regulations emissions compliance.
Acura’s advanced technologies contributing to this performance are the close-coupled catalytic converters which light-off quickly on start-up, an increased 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.
Both TSX engines feature Programmed Fuel Injection (PGM-FI) that continually adjusts fuel delivery to achieve the best combination of power, fuel economy, and low emissions. The fuel injectors likewise help reduce hydrocarbons after starting, while a linear air/fuel sensor positioned in the exhaust system just upstream of the catalyst improves air/fuel mixture control.
The inline four-cylinder engine is designed with emissions performance in mind, employing VTC™ and a unique i-VTEC® cylinder head promoting internal exhaust gas recirculation, which helps reduce NOx emissions output.
Both the V-6 and I-4 engines feature an exhaust manifold design that is integrated into the cylinder-head casting. This design allows the catalytic converter to be positioned very close to the cylinders for swift light-off after a cold engine start. A secondary catalytic converter is positioned downstream under the passenger compartment floor.
DIRECT IGNITION AND DETONATION-KNOCK CONTROL
Because accurate 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 in all conditions.
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.
NOISE, VIBRATION & HARSHNESS (NVH) CONTROL
The 3.5L V-6 is designed to effectively control noise, vibration and harshness (NVH). Featuring a high-rigidity die-cast engine block with 60-degree V-angle cylinders, a strong forged-steel crankshaft, die-cast accessory mounts and stiff cast aluminum engine oil pan, low engine NVH is ensured. The induction and exhaust system is designed to emit a refined and quiet tone at low speeds, with a sporty “growl” above 3,000 rpm.
The 2.4L I-4 engine has an array of features designed to reduce (NVH). The pressure-cast cylinder block has a bed-plate type main bearing cap that results in a highly rigid assembly, which helps to resist vibration. Two balance shafts further smooth the inherent vibration commonly found with a large-displacement inline four-cylinder engine layout. A self-adjusting, silent-type camshaft chain and serpentine accessory drive belt team to help reduce NVH.
ELECTRONIC CONTROL MOUNT (ECM)
Acura’s sophisticated Electronic Control Mount (ECM) system is used to minimize the effects of engine vibration. At low engine speed, vacuum-controlled engine mounts allow additional engine movement, so that less low-frequency vibration is transmitted to the body. At higher rpm, the ECM mounts stiffen so that the mass of the engine is properly restrained for better handling.
With the 3.5L V-6, in addition to being used for the engine, the ECM mounts are also used for the transmission.
ENGINE COMPARTMENT COVER
While the engine compartments for both models are handsomely finished, the 3.5L V-6 features an engine compartment cover that conceals accessory systems. The engine itself is visible and is finished to eliminate the need for cosmetic covers. Whereas the 2.4L I-4 TSX uses a traditional prop rod to hold open the hood, the 3.5L V-6 TSX makes use of a gas-charged strut assembly to hold open the hood. The strut setup not only delivers an improved underhood appearance, but it helps lift the hood during opening as a convenience to the user.
100,000 MILE TUNE-UP INTERVAL
All TSX models are exceptionally low-maintenance automobiles. With features like Iridium alloy-tipped spark plugs and a space-saving, self-tensioning serpentine accessory drive belt, these engines require no scheduled maintenance until 100,000 miles, exclusive of periodic inspections and normal replacement of fluids and filters. The first scheduled service at 100,000 miles includes valve adjustment, timing belt replacement, and water-pump inspection. Note that 100,000-mile tune-up interval does not apply to fluid and filter changes. Exact mileage is determined by actual driving conditions.
MAINTENANCE MINDER SYSTEM
A standard Maintenance Minder™ system automatically monitors the vehicle’s operating condition. The driver is alerted via a message on the Multi-Information Display (MID) when maintenance is required. The system helps eliminate unnecessary service stops, while ensuring that the vehicle is properly maintained.
The Maintenance Minder™ system monitors operating conditions such as coolant and oil temperatures along with engine speed, and then determines the proper service intervals. Depending on the engine operating conditions, oil change intervals can be extended to a maximum of 10,000 miles, potentially sparing the owner considerable money and inconvenience over the life of the vehicle.
The MID indicates the remaining percentage of engine oil life, and indicates when service is due via 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 system can be reset manually by the owner, and monitors all normal service parts and systems, including oil and filter, air-cleaner, tire rotation, automatic transmission fluid, coolant, spark plugs, timing belt, brake pads and more. Maintenance alerts are presented on the instrument cluster when the ignition is first turned on, and not while driving.
SEQUENTIAL SPORTSHIFT 5-SPEED AUTOMATIC TRANSMISSION WITH PADDLE SHIFTERS
Both TSX models feature a smooth shifting Sequential SportShift 5-speed automatic transmission. Although similar in design, the transmission fit to the V-6 engine is more robust to handle the substantial increase in horsepower. In addition, the transmission uses special gear ratios to take advantage of the V-6’s abundant torque. Although the I-4 and V-6 use different transmission gear ratios, the operation of the Sequential SportShift 5-speed automatic transmission is identical. Both Sequential SportShift 5-speed automatic transmissions feature racing-inspired paddle shifters and Grade Logic Control to maximize acceleration, fuel economy and driver control.
A console mounted, 5-position shift gate makes operation of the transmission simple. When in this mode the transmission operates automatically in the "D" position, selecting among the five forward gear ratios based on the driving conditions. When in automatic mode, the transmission incorporates an advanced Grade Logic Control and Shift Hold Control, both of which work to reduce gear "hunting" on hills and through turns.
Grade Logic Control reduces shift frequency and improves vehicle speed control by altering the transmission’s shift schedule when traveling uphill or downhill. The transmission computer continuously compares throttle position, vehicle speed and acceleration/deceleration with a map stored in the computer memory. The Grade Logic Control System determines when the TSX is on an upslope or down slope. The shift schedule is then adjusted to automatically hold the transmission in a lower gear for better climbing power or increased downhill engine braking.
When the throttle is quickly released and the brakes are applied, as might be the case when decelerating for a corner, Shift Hold Control keeps the transmission in its current (lower) gear ratio. This helps provide added engine braking, and ensures that abundant power is immediately available at the corner exit.
The TSX is equipped with steering-wheel mounted paddle shifters to operate the Sequential SportShift 5-speed automatic transmission. The paddle shifters are activated with a fingertip pull; the right paddle commands an upshift while a pull of the left paddle commands a downshift. A digital display in the tachometer face indicates which gear the transmission is in when the steering wheel paddles are active.
The steering wheel paddles can operate in both the "D" and "S" transmission positions. When in "D," a touch of a paddle shifter temporarily places the transmission in manual mode (but without gear holding at redline). After steady-state cruising conditions are detected, the transmission returns to full automatic operation. In “S,” engaging a paddle enables gear holding, which allows only driver-commanded shifts, with the exception of automatically shifting to First gear at a stop, even if not driver-selected.
When first placed in “S” mode, the transmission will automatically shift between First, Second, Third and Fourth gears until a paddle shifter is activated. When a paddle shifter is activated, the transmission goes into full manual mode.
Manual mode protective features
An array of protective features is active when the transmission is in manual mode to help protect the engine and drivetrain from damage. The Powertrain Control Module (PCM) will cut off fuel flow to the engine if there is a possibility of over-revving in a gear, as might occur if the driver is late in commanding an upshift. To prevent over-revving while downshifting, the transmission will not execute a driver-commanded downshift that would send the engine beyond redline in the lower gear. Even if the driver allows the vehicle to come to a stop in a high gear, the transmission will automatically downshift to First gear to prevent lugging away from a stop in a high gear.
Cooperation between 5-Speed Automatic Transmission & Drive-by-Wire™ Throttle System
With the TSX’s electronically controlled automatic transmission and Drive-by-Wire™ throttle system, the function of the engine and transmission are closely choreographed for faster, smoother shifting. As a result, shift shock is reduced significantly during shifts.
ACTIVE LOCKUP TORQUE CONVERTER
To provide good fuel economy while maintaining a high level of drivability, the 5-speed automatic transmission includes an active lockup torque converter. With the precise control afforded by a linear solenoid and assist spring, the system features a wide range of speed and throttle settings in which lockup can be engaged in the top four gears. This results in excellent fuel economy in both city and highway driving.
6-SPEED MANUAL TRANSMISSION (TSX)
Available with the 2.4L I-4 is a close-ratio 6-speed manual gearbox. With precise and light shifting action, the manual transmission is designed to compliment the TSX’s sporting side. Compared to a 5-speed transmission, the 6-speed gearbox allows for closer gear ratio staging. This enables the engine to operate closer to its power peak during acceleration for better performance with the revised engine.
A high (numerically low) top gear ratio allows for a relaxed cruising rpm, improved fuel efficiency and lower emissions. The TSX 6-speed manual gearbox has special ratios for Second through Sixth gears for better performance with the revised engine.
The compact, highly rigid transmission case is cast of aluminum alloy to reduce weight. Additionally, the highly rigid casting helps damp out noise and vibration. Multi-cone synchronizers on First through Fourth gears reduce and smooth shifting effort.
The low-effort clutch pedal design has a broad engagement band for progressive engagement and smoother launches.
The 2010 TSX reflects Acura’s advanced design direction. Forceful and muscular but at the same time sleek and elegant, the styling clearly sets the tone for the TSX’s driving dynamics - agile and invigorating for performance oriented drivers, and quiet and comfortable for those with luxury intentions.
The 2010 Acura TSX body design represents the latest direction in Acura styling. The TSX was styled in Acura’s Wako design studio (located just outside Tokyo, Japan) and is assembled at the Sayama Factory in Japan. With a wide body that provides agile handling and greater interior roominess (along with a lower seating position) the TSX continues to be the best handling front-wheel-drive vehicle in its segment.
Inside, the TSX is quiet and refined. Advanced aerodynamic treatments such as inside frame rails, underbody air deflectors and a chiseled aerodynamic body shape help the TSX move with a minimum of drag - thereby reducing fuel usage and lowering emissions, while enhancing quietness and high-speed dynamic stability.
The TSX’s dynamic styling is designed to appeal to a wide range of customers. These customers lead an active lifestyle, and often participate in outdoor activities. Thus, they want a vehicle that reflects their passion for performance and athleticism while also supporting their active social lifestyle with roomy, comfortable seating for five.
The 2010 TSX features Acura’s signature design language known as Keen Edge Styling. In keeping with this styling language, Acura designers infused crisp, dynamic design elements into the exterior design of the TSX. Additionally, the TSX’s aerodynamic design evokes both emotion and tension with a decisively sporty flair - as if a solid piece of billet material was shaped with a sharp knife.
The TSX features Acura’s signature power plenum grille - making the TSX instantly recognizable on the road. Inside the grille’s bold, chiseled chromed surround trim is a satin-black parallelogram "honeycomb" mesh that adds a look of power and performance. The headlight arrays, containing reflectors on the outside edges, piercing projector-style low-beam headlights and sculpted halogen high-beam headlights, all reside behind a smooth contoured lens. Fog lamps are located in the outer edges of the front fascia and are a standard feature on the TSX. Keen eyes will notice that the 2010 TSX V-6 makes use of a slightly redesigned front bumper assembly that features added air intake openings for improved cooling of the V-6 model’s oversized radiator.
Sharp contour lines run alongside the body and connect the front and rear of the new car together in a strong, windswept line that promises both agility and performance. Bold wheel arches that frame the five-spoke, 17-inch aluminum wheels (TSX I-4) or split five-spoke, 18-inch wheels (TSX V-6) emphasize strength and muscularity. Chrome door handles and chrome trim surrounding the side windows adds a look of substance and quality.
In back, sculptured taillights compliment large turn signals at the outside edges of the trunk lid. Twin reflectors are low-mounted on the rear fascia near the 3.2-inch diameter exhaust finishers.
WIDER BODY DIMENSIONS
The body width for the 2010 TSX is a full three inches wider than the previous-generation TSX. This increase, along with the 2.6-inch wider track and the 1.4-inch longer wheelbase, considerably improves interior roominess. There is a dynamic upside to the wider track: enhanced handling agility and stability. The seating position is also 0.4-inch lower than in the previous generation TSX, helping to create a sportier driving experience.
To improve the field of view for the driver, the TSX has thin A-pillars which permit a broader field of forward view without compromising structural strength. While a robust interior structure helps ensure the necessary structural rigidity, at 4.2 inches wide in their interior dimension, the pillars are an inch narrower than the previous TSX A-pillars. The use of thin A-pillars improves driver’s point of view and allows for best in class outward frontal field of view.
CLOSED-CHANNEL CROSS-BRACED ROOF STRUCTURE
The 2010 TSX uses a strengthened roof section designed to significantly reduce flexing and vibration, resulting in less noise in the passenger compartment. Whereas the roof section on the previous TSX used open-channel stiffeners, the new TSX’s roof section uses two closed-channel crossbeams that help create a structure that is highly resistant to flexing and vibration.
The installation method of the roof structure is unique as well. With the previous TSX, the roof panel and its open-channel stiffeners were welded onto the rest of the unit body as a unit. With the 2010 TSX, the roof frame assembly is first welded in place without the roof panel, allowing full access to the ideal welding locations. The roof panel itself is then attached. This process creates stronger joints and a stiffer overall roof and body structure - 35 percent greater rigidity in front and 20 percent greater rigidity in back. The end result for the TSX owner is markedly decreased noise and vibration inside the car.
FRAME RAIL SYSTEM
The TSX uses an internal frame rail system for reduced aerodynamic turbulence and drag. In addition by positioning the stamped steel frame rails above the floor of the passenger compartment - instead of below it - the bottom of the vehicle can be made much flatter resulting in a quieter ride at highway speeds.
CIRCULAR-TYPE REAR BULKHEAD STRUCTURE
A circular-type rear bulkhead structure significantly improves structural rigidity of the rear area of the passenger compartment, measurably reducing noise and vibration experienced by passengers.
Careful attention to airflow management helps increase fuel efficiency, reduce emissions and improve stability at higher speeds and in crosswinds. Visible elements of the TSX’s aerodynamically efficient body design include flush mounted headlights, hidden windshield wipers, flush mounted side and rear glass, and a tail that cuts off airflow abruptly instead of inducing drag. The aero improvements continue under the vehicle with a series of plastic moldings that redirect air to reduce turbulence underneath the car.
Underbody aerodynamic aids include:
- A short, wide wickerbill underneath the front fascia that helps separate the airflow and allows it to move underneath the engine and transmission assembly with the least drag.
- A large aluminum and plastic undercover that further improves airflow beneath the engine and transmission.
- A pair of deeper, separate air "strakes" located in front of the front tires to help air flow efficiently around the tires.
- A pair of covers located in front of the rear suspension subframe that help improve airflow.
The TSX make use of extensive insulation features to reduce the interior sound level. Four separate strategies are employed:
- A thorough insulation package including melt sheet is applied to lower unit body areas.
- The floor carpet provides sound absorption and insulation to markedly reduce road noise in the passenger compartment.
- Floating front and rear suspension subframes are rubber mounted to reduce road and suspension noise, vibration and harshness (NVH).
- A, B and C-pillar separators (see below) are also used.
A, B & C-PILLAR SEPARATORS
In vehicles, generally the A-, B- and C-pillars that extend vertically from the floor of the vehicle to the roofline are hollow, which can transmit road and wind noise into the passenger compartment. The TSX pillars are sealed internally, dramatically reducing the transmission of noise and vibration.
WIND NOISE REDUCTION MEASURES
A comprehensive series of features dramatically reduces audible wind noise inside the TSX - especially at higher speeds or in windy conditions.
Wind noise reduction measures include:
- Inside frame rail system positions structural frame rails above the floor rather than below it. This smoothes the bottom of the vehicle for reduced air turbulence.
- A series of underbody fairings controls airflow underneath the car and around the front and rear tires.
- Windshield wipers and arms are positioned below the hood line.
- Flush window and moonroof moldings reduce air turbulence.
- Exterior mirror housings are aerodynamically shaped to further reduce turbulence.
The TSX uses projector-style Xenon High Intensity Discharge (HID) low beam headlights and 60-watt halogen high beams, plus a bright incandescent taillight array and bright Center High Mounted Stop Light (CHMSL). Bumper-integrated front fog lamps are standard and bright backup lights are incorporated into the edges of the trunk lid.
A range of new exterior colors (including a choice of four pearl and four metallic colors) are designed to compliment the TSX’s new styling. Body colors are applied with a waterborne paint process to reduce environmental impact and waste.
The TSX features a power sliding moonroof that is flush mounted to reduce wind noise as well as featuring an inner panel that further reduces noise from entering the passenger compartment when the moonroof is closed. A pop-up wind deflector reduces turbulence and noise when the moonroof is open.
For ease of operation, a one-touch switch is located ahead of the moonroof on the ceiling. The switch controls open/close as well as tilt functions. The moonroof also features an auto-reverse feature for safety and may be operated after the ignition is turned off (until the driver’s door is opened).
The 2010 TSX is equipped with both driver and passenger-side front power auto up/down windows. With one light touch of the window switch the windows will either lower all the way or rise all the way. An auto-reverse feature reduces the likelihood of injury in the event that a passenger’s hand or arm is extended out the window while it is closing.
The TSX’s passenger-side power-activated exterior rearview mirror features a Reverse gear tilt-down feature. At the driver’s discretion (the feature may be switched off), when Reverse gear is engaged, the passenger side mirror automatically tilts downward to provide an improved view of curbs or painted lines. The mirrors are also heated to improve rear visibility in foggy or icy conditions, and feature a special tint to reduce glare. The mirror housings are designed for good aerodynamics and incorporate turn indicators at the outer edges of the housings.
ELECTRIC FUEL DOOR LOCK
The TSX’s fuel-filler door locks and unlocks automatically along with the doors. By eliminating the need to reach for the traditional floor-mounted cable release, the new system simplifies the process of refueling the car. As long as the driver’s door is unlocked, opening the fuel-filler door is as simple as gently pushing on the rear edge of the door to release its latch. Latching the door requires a gentle push.
All exterior window glass on the TSX, including the laminated front windshield, safety-glass side and rear windows, have a special UV-resistant coating that helps reduce interior temperatures, lessens glare, and helps protect the leather and other surfaces inside the vehicle from fading.
DOOR EDGE GARNISH
To provide a more finished interior appearance, an attractive metal garnish covers the inside edges of front and rear door ends except for the door latch (and the child safety locks on the rear doors). This improves the visual appeal of the doors when they are open.
The TSX features a wide and usable trunk that makes loading bulky or heavy items significantly easier. Widely spaced trunk lid hinges provide greater clearance, and when closed, the hinges disappear into slots in the finished trunk lining and do not intrude on cargo space. Plus, the hidden hinge design improves trunk aesthetics and gives a more high-quality feel. The fully lined and illuminated trunk can accommodate a wide range of cargo, including four golf bags or four Pullman suitcases.
The TSX’s trunk latch may be released with the remote transmitter built into the folding ignition key, via a pushbutton on the rear fascia (when the doors are unlocked) or by pushing a button on the driver’s inside door panel. An emergency cable release is available in case the TSX battery should ever run down.
An exciting line of Acura Genuine Accessories was developed simultaneously with the TSX to provide personalization for the Acura client. Like all Acura Genuine Accessories, the TSX accessories are covered by a 4-year/50,000-mile limited warranty.

A HomeLink® remote control system is also standard. The available Technology Package adds a dazzling 10-speaker Acura/ELS Surround® Premium Sound Audi o System with Note feature for XM® Radio, Acura Navigation System with Voice Recognition™ with rearview camera and AcuraLink® Satellite Communication System.
The TSX’s sport-oriented interior is designed to evoke a premium, avant-garde appearance with a blend of high-quality materials and graceful accents. Interior shapes are sweeping and fluid, and vehicle entry is over metal sill plates bearing the Acura logo. Satin metal finish accents arc across the instrument panel and along the sides of the center console. Both front and rear doors have sweeping armrests that are integrated with the door pulls, handles and lock knobs for a more integrated and finished look.
Large analog gauges are easily legible, and the small-diameter steering wheel has a thick, leather-wrapped rim for a sporting feel. Satellite controls for key systems are positioned on the steering wheel within fingertip reach, including racing-inspired steering wheel mounted paddle shifters for the 5-speed automatic transmission. A large digital display within the tachometer face shows gear selection when the transmission is in manual mode. The interior comes in three premium colors: Ebony, Parchment and Taupe.
The TSX is designed to provide the driver with a functional and refined cockpit that puts controls within easy reach. The key controls – the steering wheel, pedals, and console shifter – are positioned for comfort and control.
Sport-oriented seating offers added lateral support for hard cornering. The 8-way power adjustable driver’s seat is positioned low for improved headroom and a lower center of gravity. The seat includes a 2-position memory feature. The steering column tilts and telescopes to accommodate drivers of varying sizes.
Instrumentation and controls are clearly legible and switchgear offers precise tactile feedback. Automatic and manual transmissions are offered with the TSX, and both are designed for ease of operation. The 6-speed manual transmission has short throws like those of a sportscar. The Sequential SportShift 5-Speed automatic transmission has a simplified straight-style shift gate located on the center console along with racing-inspired paddle shifters that are within fingertip reach on the steering wheel.
Controls for the power moonroof with tilt and auto-open/close are located overhead in an intuitive location. The trunk can be electrically opened via a button positioned within easy reach in the driver’s door panel. The fuel filler door is locked electrically anytime the doors are locked, eliminating the need for a cable-style fuel door release button. When the power door locks are unlocked, the fuel filler door can be easily opened.
LEATHER-WRAPPED STEERING WHEEL
In keeping with its sporting mission, the TSX has a thick leather-wrapped 3-spoke steering wheel that integrates many control functions. Audio controls are positioned on the left spoke while cruise-control switches are on the right spoke. On cars equipped with the Technology Package, Acura Navigation System with Voice Recognition™ controls are located on the bottom spoke of the steering wheel. When equipped with the Sequential SportShift 5-speed automatic transmission, a pair of shift paddles are positioned on the rear of the steering wheel.
LED INSTRUMENTATION WITH MULTI-INFORMATION DISPLAY
The TSX’s analog instrumentation has satin metal-finish bezels and a clean, uncluttered look that makes it easy for the driver to interpret readings. LED backlighting makes the large gauges clear – day or night. The illuminated pointers on the tachometer and speedometer are "floating," and appear to sweep around an invisible center pivot. When equipped with the Sequential SportShift 5-speed automatic transmission, the tachometer face includes a digital gear selection indicator. The V-6 model receives an updated tachometer face with a unique rpm redline range that corresponds to the operating parameters of the new 3.5L V-6 engine.
A Multi Information Display (MID) positioned in the speedometer face displays outside temperature, vehicle mileage and trip mileage, instant as well as average fuel economy readouts and TPMS tire pressure status. Maintenance Minder™ also alerts the driver of upcoming maintenance needs via the MID.
To give the TSX a welcoming feel, when the door is first opened, the instrument lighting comes on at a low brightness; when the key is put in the ignition, the brightness progressively increases to 100-percent illumination. Then when the ignition is turned on, the illuminated instruments come to life, indicating that all systems are up and running. At the end of the drive, the illumination process reverses.
During spirited acceleration, cornering and braking, secure seating for the driver and passengers is an elemental part of overall comfort. With high lateral loadings the driver’s seat becomes an important part of the control system, helping the driver read the dynamic information the chassis and powertrain convey. The TSX driver’s seat is designed to deliver a sense of connection and control, and is scaled to fit a wide range of body shapes. Specific attention was given to increasing shoulder-area support for enhanced comfort while cornering.
With 8-way power adjustability, the TSX driver’s seat provides an accommodating fit and two different seat position profiles can be stored in memory. Each seat profile is linked to one of the pair of new folding ignition keys with integral remote-entry transmitter. When the driver uses the remote entry feature of the key, the TSX automatically adjusts the driver’s seat to the preset position as well as links the driver’s side mirror and radio presets. Switches located on the driver’s door panel can also select the individual memory profiles.
The driver’s seat backrest lumbar mechanism is adjustable via a lever mounted on the right side of the seat back. The mechanism is designed to offer smoothly contoured support without the "sharp edged" feel of some less sophisticated mechanisms. TSX is equipped with a 4-way power adjustable front bucket seat for passenger comfort. To eliminate the chill on cold days, the TSX features heated front seats.
The TSX’s wide wheel track and overall body width translate into a spacious interior cabin. The TSX’s efficient packaging offers comfortable long-haul space for four passengers, and can accommodate up to five passengers for shorter drives. Rear seat room is particularly impressive relative to this class, with adequate leg and headroom for passengers over six feet tall.
CARGO CARRYING VERSATILITY
When more space is needed, the lockable 60/40 split-folding rear seatback can be lowered by pulling release handles that are easily accessible from inside the trunk. This opens a large cargo pass-through to the back seat area. The reconfigured pass-through is now eight inches wider at its bottom, simplifying loading. Trunk cargo volume is 12.6 cubic feet with a total vehicle cargo volume of 107.1 cubic ft.
COMFORT AND CONVENIENCE ITEMS
The TSX interior is designed to help make passengers comfortable with plenty of customer-relevant features. Front and rear cupholders accommodate large drinks, convenient storage bins and compartments include seatback map pockets and bottle holders in all four doors, and the front door panels also have large map pockets. A 2-section locking glove compartment has a damped door, and there is also overhead sunglasses storage, while the center console incorporates side utility pockets. Beneath the sliding, padded armrest, the center console storage compartment has an internal 12-volt power point, a 2.5 mm auxiliary input mini-jack for the audio system, and a USB jack for the easy connection of a compatible audio device (such as an iPod®) to the TSX’s sound system.
A versatile Multi-Information Display located in the speedometer face tracks the car’s maintenance needs, shows warnings and offers an array of driver preference settings. The TSX also features a dash mounted electronic compass for added directional information while driving. Illuminated door-mounted window switches are easy to locate at night. A HomeLink® remote system allows the control of up to three home electronic devices remotely from inside the car.
DUAL-ZONE AUTOMATIC CLIMATE CONTROL SYSTEM
The TSX has standard dual-zone automatic climate control with clear, intuitive controls. A replaceable filter system helps remove particulates from the interior air. When equipped with the Acura Navigation System with Voice Recognition™, key HVAC system functions can be accomplished via voice commands. In addition, the navigation system calculates sun position to adjust system operation from side to side to help compensate for solar heating.
INTERIOR COLOR & TRIM COMBINATIONS
Three interior colors are available, including Ebony (black), Taupe (gray) and Parchment (ivory). The upper instrument panel in all versions is black, while the lower instrument panel color matches the interior color.
Two folding ignition keys with integrated remote transmitters are provided with the TSX. Each transmitter can be linked to one of two driver seat-position profiles. The key fob that is used to unlock the vehicle triggers a specific driver profile and the system automatically positions the power driver’s seat, adjusts the side mirrors and sets the radio presets to match that profile.
Using the key fob, one push of the unlock button unlocks the driver’s door while a second push unlocks all the doors. When placed in the driver’s door lock, one twist unlocks only the driver’s door while a second twist unlocks all the doors.
The TSX also features a unique "quick vent" feature that (when holding the unlock button on the keyless remote for two seconds) instantly lowers all four door windows and opens the power moonroof to quickly vent the built-up interior heat. In addition, by holding the key in the "lock" position, all open windows can be simultaneously raised.
BLUETOOTH® HANDSFREELINK® WIRELESS TELEPHONE INTERFACE
The TSX includes standard Bluetooth® HandsFreeLink® cellular telephone and music interface that is designed to work with many Bluetooth® enabled mobile telephones (sold separately). Bluetooth® is a radio frequency-based technology that allows portable devices such as mobile telephones, PDAs, laptops and other devices to communicate wirelessly. Acura’s Bluetooth® 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 cellular telephones should have the HFP. After a simple one-time pairing process, the TSX can communicate wirelessly and securely with the driver’s cell phone when it is within approximately 30 feet (10 meters) of the vehicle. The phone must be turned on, but can be stowed in a pocket, briefcase, purse, or anywhere inside the TSX cabin.
Using the Bluetooth® HandsFreeLink® system, the driver can send or answer telephone calls without needing to remove hands from the steering wheel. Incoming telephone numbers are displayed on the Multi-Information Display, and a ring tone is heard over the TSX’s audio system. A press of the steering wheel-mounted "Pick up" button mutes the audio system and the incoming caller is heard over the audio system speakers. An overhead microphone picks up the driver’s voice. "Echo effect" and background noise are reduced by special algorithms built into the navigation system to improve the transmission quality of the driver’s speech.
To send a telephone call hands-free, fingertip controls mounted on the steering wheel activate the system and the driver can dial the telephone number by voice. The driver also can store frequently called numbers in the system’s memory by using voice tags. Up to six different compatible mobile phones can be paired with the TSX’s Bluetooth® HandsFreeLink® system at one time.
PREMIUM 7-SPEAKER SOUND SYSTEM WITH CD AND AM/FM/XM® TUNER
The TSX’s Premium audio system delivers a high performance listening experience. Engineered for simple, intuitive operation, the system incorporates an AM/FM tuner, XM® satellite radio and a single-disc CD player. The system displays Radio Broadcast Data System (RBDS) information, which appears as text showing station name and program type.
Multiple audio sources
The audio system can play program material from a wide variety of sources. The single-disc CD player can read discs encoded with MP3 or WMA® files, and there is a 2.5 mm auxiliary mini-jack in the center console for use with an external MP3 player. A USB port and cable is provided in the center console for the easy connection of an iPod® or compatible MP3 player. When used with compatible iPod® models, the USB connection provides charging power and allows the display of iPod® content information on the audio system head unit. Control of the iPod® is via the audio head unit for maximum convenience.
Standard equipment is XM® Satellite Radio, offering over 170 digital channels of news, sports, talk and entertainment. A 90-day complimentary subscription to XM® is included.
The audio system also offers Bluetooth® Audio, a new technology for Acura. When the system has been paired with a compatible cellular telephone that incorporates a built-in audio player, the phone’s audio content can be played on the TSX audio system via a wireless Bluetooth® connection. With the phone turned on and its music player running, the TSX audio system allows control of volume, forward and back track skipping along with pause/resume via the vehicle’s audio head unit (function not legal in all states).
360 watts of power
The 360-watt sound system has a total of seven speakers. A pair of tweeters are positioned in the top of the instrument panel, and two 6.3-inch drivers are positioned in the front doors. The rear deck has another pair of 6.3-inch drivers, along with an 8-inch subwoofer. An in-glass antenna located in the rear window is optimized to help deliver enhanced radio reception. Remote audio controls on the 3-spoke steering wheel put frequently used functions within fingertip reach of the driver.
ACURA/ELS SURROUND® PREMIUM AUDIO SYSTEM WITH 10-SPEAKERS, DVD-AUDIO, DTS™, CD 6-DISC CHANGER, AND AM/FM/XM® TUNER
When equipped with the available Technology Package, the TSX includes an Acura/ELS Surround® Premium Audio System featuring 10-speakers and DVD-Audio. The system gets its name from multi-Grammy® Award winning producer/engineer Elliot Scheiner’s recording industry-recognized moniker "ELS®." Scheiner’s goal in the development of this audio system was to capture and reproduce music the way it is heard in the recording studio. The sophisticated ELS® system, developed together with Panasonic Automotive Systems, is designed to provide recording studio sound to the interior of the TSX. The system uses 10 speakers and a total of 415 watts of power to create a unique listening experience in the TSX.
Like the 7-speaker Premium audio system, the Acura/ELS Surround® Premium Audio system can play program material from an extremely wide range of sources. The 6-disc CD changer can read discs encoded with MP3 or WMA® files. There’s a 2.5 mm auxiliary mini-jack for use with an external MP3 player, and a USB jack and cable is located in the center console for the connection of an iPod® or compatible MP3 player. When used with compatible iPod® models, this connection provides iPod® control via the audio head unit. Bluetooth® Audio allows a compatible cellular telephone that incorporates a built-in audio player to wirelessly play the phone’s audio content on the TSX audio system (function not legal in all states).
The audio system features selectable Dolby Pro Logic II signal processing that creates simulated 5.1-channel surround sound from CD, MP3/WMA®, XM®, AUX and USB input. The TSX audio system plays conventional CDs and DTS discs, in addition to DVD-Audio discs. While Elliot Scheiner and Panasonic Automotive tuned the Acura/ELS Surround® Premium Audio system to create outstanding sound from any source, DVD-Audio is the system’s most impressive sounding format. This advanced audio reproduction technology delivers over 500-times higher resolution than traditional CD audio. DVD-Audio delivers smoother, fuller and far more accurate sound through six discrete channels. (The system will not play DVD movies, DVD-V or DVD-R/RWs.)
To make this capable system simple to operate, it has large-format controls and steering wheel-mounted controls of key functions are positioned within fingertip reach. Select audio system functions can also be executed via voice commands.
Each of the 10 speakers in the Acura/ELS Surround® Premium Audio system uses a high-energy Neodymium magnet for excellent sound quality and to reduce weight. There are soft-dome tweeters in the mirror patch location, plus a 2.75-inch midrange polypropylene-cone center speaker in the middle of the dashboard top. Each of the doors has 6.7-inch full-range dual-thickness polypropylene-cone speakers, and in the rear parcel shelf there are two more 6.7-inch drivers flanking a special Super Low Distortion 8-inch diameter subwoofer. The combination of outstanding speaker drivers, 415 watts of power and optimal speaker locations creates an audio system that delivers luxurious sound to any seating position.
An AM/FM tuner gets signals from a powered, active glass antenna laminated into the rear window glass. The system displays Radio Broadcast Data System (RBDS) information, which can show station name and program type. XM® Radio is integrated into the audio receiver to provide more than 170 channels of digital program material with near-CD quality sound. When XM® is used, a display shows the current station, song title, or artist’s name. A complimentary 3-month subscription to XM® Radio service is included with purchase of a new TSX, and customers are able to continue or cancel the service any time after. There are numerous XM® Radio service packages available.
A new Note feature for XM® Radio is built into the audio system. The feature is designed to be a convenience for TSX owners that want to make note of a song heard on XM®. At the touch of a button or via a voice command, the Note feature records the current song title and artist name in text form, along with a short audio excerpt of the song. The system captures up to 10 seconds of each selected song, and can record a total of 30 song excerpts for later playback.
ACTIVE SOUND CONTROL (V-6 Exclusive)
The 2010 TSX V-6 receives a new Active Sound Control system that is much advanced over Acura’s previous Active Noise Cancellation™ (ANC) system. Whereas ANC dealt specifically with the elimination of low sound pressure entering the cabin, the new Active Sound Control system has a much broader range including the elimination of unwanted high frequency noise. In addition, Active Sound Control is linked to throttle position and engine rpm to provide a more quiet cockpit during normal cruising while allowing the 3.5L’s muscular sound to be heard more during higher rpm, higher speed driving.
Sporting a new array of processing technology and sensors, the Active Sound Control system not only dramatically improves sound cancellation but also works throughout the entire engine rpm range whereas the previous ANC system only worked to cancel engine booming noise up to 2,000 rpm. Moreover, Active Sound Control is specially tuned for various levels of "effect" generated at different throttle positions: during low rpm, Active Sound Control delivers a quiet cabin; during mid-rpm throttle, some of the throaty exhaust note is allowed to enter the cabin; and during high rpm the Active Sound Control system is tuned to allow a more crisp exhaust note to enter the cabin.
The Active Sound Control system operates whenever the car is running, regardless of whether the audio system is on or off. There are two microphones mounted in the headliner- one just behind the front overhead console and another just ahead of the overhead rear light module. The microphones capture low frequencies entering the cabin, and send a signal to the Active Sound Control unit. The Active Sound Control unit then creates a precisely timed reverse phase audio signal that is sent to an amplifier, which powers the door speakers.
The Active Sound Control dramatically reduces the booming noise of the exhaust, front and rear. In the frequency range below 100 hertz, Active Sound Control results in an impressive 10 dB reduction in noise level. Moreover, the new Active Sound Control system dramatically reduces high frequency and middle-frequency noise attenuation during normal cruising. In addition, road noise attenuation is also improved over both smooth and rough roads.
ACURA NAVIGATION SYSTEM WITH VOICE RECOGNITION™ AND REAR-VIEW CAMERA, ACURALINK® REAL-TIME TRAFFIC AND ACURALINK® WEATHER
The TSX with Technology Package features the Acura Navigation System with Voice Recognition™ with an 8-inch screen. For 2010, the navigation system gets an easier-to-read outer screen that further thwarts glare. Designed for easy, intuitive operation, the TSX’s navigation system has a wide range of capabilities. A rearview camera helps provide added situational awareness for the driver when the vehicle is in reverse. The navigation system features AcuraLink Real-Time Traffic™ along with AcuraLink Real-Time Weather™.
The Acura Navigation System with Voice Recognition™ locates the vehicle’s position based on data from up to 12 orbiting Global Positioning Satellites (GPS). In situations when the GPS antenna is blocked by tall buildings, a parking garage or tunnel, an internal gyroscopic system and a speed sensor help keep the mapping information current and reliable until satellite reception is restored. The system’s ECU features a mapping information database that’s stored on a replaceable DVD. Updated DVD data discs are available (for a fee) on an annual basis at www.acura.com or by calling 888-549-3798.
There are two ways to control the navigation system: by voice command or via an Interface Dial. With a press of the "Talk" button on the steering wheel, voice command is enabled. The system responds to 100,000 words, as well as to 1.7 million spoken city and street names.
Audio sound is automatically muted when the "Talk" button is pressed, and an overhead microphone array receives spoken commands from the driver. The pair of microphones in the ceiling console work with sophisticated electronics to "home in" on the driver’s voice while ignoring extraneous sounds. The improved clarity of this microphone system is a key factor behind the spectacular improvement in the word recognition of this new-generation navigation system.
The system responds to commands in normal English, such as "Display gas stations," "Find nearest hospital" or "Find nearest Chinese restaurant." You can also choose to display points of interest on the map with voice command, or tell the system to provide turn-by-turn navigation. The system’s massive point-of-interest database includes phone numbers, which can be dialed with the Bluetooth® HandsFreeLink® system when linked to a compatible Bluetooth® cellular telephone. The system also features Zagat Survey™ information and reviews for thousands of restaurants.
The TSX has a convenient Interface Dial that provides an alternate way to control the navigation system. The dial allows characters and items to be selected from the on-screen display, functioning much like a computer pointing device. The Interface Dial allows you to choose menu options or spell out words (an address, business name or place).
AcuraLink® Satellite Communication System
The TSX navigation system includes the AcuraLink® Satellite Communication System. AcuraLink® provides 2-way communication between Acura and the vehicle, giving clients the latest information specific to their vehicle. The owner’s Bluetooth® compatible cellular telephone is used in cases where communication to and from the Acura Telematics server is needed (once the owner has paired a phone with the vehicle, enabled its data-transmission function and agreed to the data charges from their cellular phone service).
AcuraLink® messages are displayed as text on the navigation screen, and can be heard over the audio system as Text-to-Speech. High priority messages are displayed immediately upon receipt. Less time-critical messages trigger an icon on the navigation screen. Some low priority messages show up only upon vehicle start-up to avoid distractions. The TSX owner can choose to read a message immediately, or archive it to be read later.
Messages that may be sent to the TSX via AcuraLink® include Maintenance Minder™ (information regarding the next required maintenance), Quick Tips (information to help maximize the benefit and enjoyment of TSX features), Feature Guide (supplements to the Owner’s Manual), Diagnostic Info (information and instruction should an onboard system issue arise), information regarding required service or repair, and service appointment reminders. The TSX owner has control over the types of messages received, and all AcuraLink® preferences can be set via the Owner Link® website.
With 2-way data communication between the TSX and the Acura Telematics Server, AcuraLink® can offer important information that previously has been unavailable. If a vehicle fault develops and an instrument panel warning indicator illuminates, AcuraLink® will automatically send a trouble code to the Acura Telematics Server (if a linked telephone is in range and the user has authorized data transmission). The Telematics Server interprets the code and then sends a message back to the vehicle. As a result, the owner knows if a particular problem can be dealt with later or if it requires special driving techniques. The data connection is enabled even if the monthly XM® Radio service package is not activated.
AcuraLink® Real-time traffic and AcuraLink® weather information
AcuraLink® Real-time traffic
The TSX navigation screen can display continuously updating traffic information including flow (with traffic speed where available), collisions, unique incidents, and construction on freeways in 77 major metropolitan areas within the continental United States. NAVTEQ™ gathers information from multiple sources including police and highway patrol accident reports and transportation departments. This traffic information is then transmitted by XM® Radio satellites to the TSX where it is graphically displayed on the navigation system.
Map icons can be selected to see incident details. Traffic information is continuously updated, allowing drivers to avoid freeway congestion en route and to choose the optimum route for their destination. AcuraLink Real-Time Traffic™ provides an updated flow of relevant information reflecting conditions along a driver’s chosen route, unlike radio or television traffic reports that typically contain less detailed information.
The TSX’s satellite-based Navigation system features Traffic Rerouting™ functionality, utilizing updated data from AcuraLink Real-Time Traffic™ information. When traffic congestion or road incidents are detected along the selected drive route, Traffic Rerouting™ can automatically recalculate a "detour" route and display a pop-up box signifying the route change. The TSX driver can also recalculate a route in manual mode simply by selecting "TRAFFIC INCIDENTS" from the Map Info menu followed by selecting the "AVOID" command relevant to an incident. Either method can save time and frustration, thus keeping the Acura driver ahead of the curve. (Note: Traffic Rerouting™ requires a monthly subscription to the XM® NavTraffic service).
Following the 3-month free trial period, Real-Time Traffic™ data services are offered on a subscription basis for a nominal fee. In addition to the on-screen traffic information, TSX owners who maintain their Sirius XM® Radio service also receive 77 city-specific audio traffic information that runs on a 2-3 minute loop in selected metropolitan areas.
Acura was the first automotive company to offer continually updated "real time" traffic information as standard equipment. Acura leads the field by offering an in-dash, in-map navigation system with continually updated weather information integrated within a single-screen format.
AcuraLink Real-Time Weather™ is the first personal weather tracking system for in-dash automotive GPS navigation systems. The system tracks area-specific, continuously updated weather conditions between the current location and the final destination. Plus, it provides near-term weather forecasts. Rather than just offering general weather conditions for a region, the system focuses on the specific weather on the driving route. AcuraLink Real-Time Weather™ information is continuously updated and delivered to the vehicle navigation system via the TSX’s built-in XM® tuner.
With data provided by Baron Services, Inc., professional-grade weather information (obtained and deciphered from a complex array of National Weather Service information) is now exclusively available to Acura owners. Owners of a new TSX will receive a complementary 3-month trial subscription that delivers AcuraLink Real-Time Weather™ along with AcuraLink Real-Time Traffic™ and XM® Radio. Afterwards, AcuraLink Real-Time Weather™ is individually available by monthly subscription or packaged with AcuraLink Real-Time Traffic™ or XM® Radio, or as a combined package of all three features.
Based on XM’s WX Weather feature that is the recognized weather information leader in the aviation and marine markets, the AcuraLink Real-Time Weather™ technology is further enhanced for specific travel conditions within most major metropolitan areas across the 48 contiguous United States. The information focuses on identifying potential weather threats along with current and future forecast weather conditions.
Current weather conditions are displayed on the navigation screen in an easy-to-read format. To find nearby weather conditions, the TSX’s navigation system cursor can be moved to the desired location on the map to obtain info for a specific location. After pressing the "Map" button, the display reverts to the vehicle’s current location.
In addition to providing continually updated weather information, AcuraLink Real-Time Weather™ also generates prompts with unique icons informing the TSX driver if the vehicle is headed into oncoming severe weather such as a developing snowstorm, ice or even a tornado warning. With such advance information the TSX driver can choose to reroute a trip to avoid the severe weather before actually encountering it.
When the navigation map display is zoomed out all the way to reveal the entire United States, AcuraLink Real-Time Weather™ shows weather patterns across different areas of the country. AcuraLink Real-Time Weather™ also offers 1- and 3-day weather forecasts for specific areas of the United States.
In keeping with its lean, athletic appearance, the 2010 TSX offers a flat ride that is free from excessive pitching motions, along with outstanding agility and steering precision. Several chassis development such as a highly rigid body design with a cross-braced roof structure and a safety cage-type rear bulkhead structure all help contribute to the TSX’s dynamic performance.
The TSX suspension’s high roll center (the geometric axis on which the body rolls or leans while cornering) reduces body lean during cornering, which better equalizes the workload for all four tires while also improving passenger comfort.
Double-wishbone front suspension components include stamped-steel upper A-arms, cast-iron steering knuckles, cast-iron lower A-arms, coil-over dampers and a large front stabilizer bar. A steel subframe cradles the engine, transmission and lower suspension components, and mounts on rubber bushings tuned to reduce road and engine noise, vibration and harshness (NVH) without compromising handling agility or steering precision.
For the 2010 TSX with the new V-6 engine, the front suspension has been upgraded with unique front springs and revised dampers. The revised suspension accounts for the increased weight of the 3.5L V-6 engine and generates a level of sporty handling that buyers will expect from the powerful V-6 TSX model.
The multi-link rear suspension includes stamped-steel upper A-arms, cast aluminum knuckles, double lower tubular lateral links, tubular steel toe-control links, coil-over dampers and a large stabilizer bar. This system provides outstanding agility and handling, together with a flatter ride and excellent control of noise, vibration and harshness (NVH).
The 2010 TSX features dual-mode dampers. While most conventional dampers are tuned to provide a compromise between ride comfort and sporty handling at different speeds, the TSX’s dual-mode dampers are engineered to provide ideal damping rates at both low and high speeds.
With a typical suspension, damping forces rise with the speed of damper compression, such as occurs when the vehicle encounters road irregularities at high speed. This can cause significant ride harshness and noise that reduces passenger comfort and enjoyment. However, the TSX’s dual-mode dampers are tuned to provide the ideal damping rates for comfort and smoothness at low speeds of damper compression, while also limiting the maximum damping forces to reduce ride harshness at higher speeds of damper compression. In this way, the TSX provides a wider range of comfortable ride quality and exceptional road holding under a wide variety of driving speeds and conditions.
Deflector plate technology
Acura’s dual-mode dampers automatically adjust compression damping characteristics to suit the vehicle speed, cornering forces and road surface. The dampers use a unique "deflector plate stack" that deflects when the compression forces reach a certain level, such as when encountering a large bump or dip in the pavement at high speeds. When these severe forces act on an ordinary damper, oil cannot move quickly enough through the damping orifices and the effective damping rate climbs, resulting in an excessive shock transmitted into the vehicle body.
With the TSX’s dual-mode dampers, when severe conditions are encountered, the plate stack deflects, allowing oil to pass through at a much higher rate and in essence "capping" the damping rate at a preset level. Allowing an increased flow rate in extreme situations noticeably reduces the shock transmitted into the vehicle body while enhancing handling stability and road holding.
Deflection of the plate stack is carefully calibrated and controlled by spring pressure force on the plate stack. The simplicity of the dual-mode damper system also means that no electronics or movable valves are required.
ELECTRIC POWER STEERING (EPS)
The TSX uses Electric Power Steering (EPS) which regulates steering via a computer-actuated electric motor. The computer-controlled EPS, advanced algorithms built into the operating software allow fine-tuning of the required steering forces so that minimal force is required at low speeds - such as when parking or maneuvering. Progressively higher steering effort is needed at higher speeds - such as when driving on the freeway.
The EPS system found in the TSX is an evolution of an earlier EPS system found on the Acura NSX supercar. Its key features and advantages include:
- The TSX’s EPS system reduces the steering effort at low speeds, improving agility and ease of effort.
- Rigidity of the steering mount is higher, which allows a much more precise and "connected" feeling during high-speed maneuvers such as lane changes or winding mountain roads.
- The steering assist is programmed via computer algorithms according to vehicle speed rather than engine speed, allowing designers the flexibility of tailoring the steering feel to match driving conditions, especially high-speed driving. The steering boost algorithms are minutely altered for every 1 km/h (0.6 mph) change in vehicle speed.
- EPS employs a sporty, 13.5:1 steering ratio which further improves driving agility.
- In its evolution from the original NSX system, the TSX’s EPS system uses a significantly more powerful electric motor teamed with a more sophisticated microprocessor.
- By eliminating the conventional power steering pump, EPS uses less engine power, benefiting acceleration and fuel economy.
4-WHEEL DISC BRAKES WITH ABS
The 2010 Acura TSX features 4-wheel disc brakes. The front rotors measure 11.8 inches in diameter and are made of cast iron with radial vents for excellent heat dissipation and wear properties. At 11.1 inches diameter, the rear rotors provide enhanced braking capability during repeated use. Floating-style single-piston cast-iron brake calipers are used front and rear. For the TSX V-6, special rear brake pads are used. In addition, the V-6 model makes use of a larger brake master cylinder, a revised pedal ratio and a new brake booster to deliver a more performance minded braking feel.
A sophisticated 4-channel Anti-lock Braking System (ABS) is standard and works in concert with the vehicle’s Traction Control System (TCS), Brake Assist, and Vehicle Stability Assist (VSA) systems for an outstanding array of electronic dynamic aids.
WHEELS AND TIRES
The 2010 TSX comes standard with 17x7.5-inch five-spoke aluminum alloy wheels and Michelin Pilot HX MXM4 P225/50R17 93V all-season tires developed specifically for the vehicle. For TSX V-6 models, the wheels are upgraded to 18x8-inches in size and are fit with performance minded Michelin Pilot HX MXM4 P235/45R18 94V tires. All TSX wheels have a clear-coat aluminum finish designed to compliment the exterior color choices. Located under the trunk floor panel is a T135/80D16 temporary spare tire mounted on a 16x4-inch steel wheel.
Dynamic testing and final chassis tuning for the new TSX was conducted both in Japan and America. The TSX was specifically tuned for the best combination of agility and handling needed in an urban environment and at higher speeds. The Los Angeles area, with its huge variety of road surfaces, freeways and topography, proved invaluable in chassis tuning the chassis achieve a balanced overall package. Also invaluable was a "mini-Nurburgring" test course built in Japan especially to replicate some of the most demanding elements of the famed German racetrack.
The 2010 Acura TSX provides an extremely high level of standard safety equipment. Key safety technologies include the Advanced Compatibility Engineering™ (ACE™) body structure, a total of six airbags, and the first use of active front head restraints on the TSX model. In addition, due to its heavier weight (versus the four-cylinder model), the 2010 TSX V-6 features a special polypropylene foam box added to the front bumper beam to provide enhanced energy absorption during a frontal impact.
In 2009, Acura became the first and only automobile nameplate to earn the Insurance Institute for Highway Safety (IIHS) prestigious TOP SAFETY PICK rating for every vehicle in its entire line-up. To accomplish this safety milestone, all 2009 Acura luxury sedans and SUVs received the highest possible rating in each IIHS crash test and feature the Acura Vehicle Stability Assist™ (VSA®) electronic stability control system as standard equipment.
The IIHS top crash safety ratings are a direct result of Acura’s "Safety Through Innovation" initiative that is based on the brand’s commitment to leadership in safety. The initiative’s goal is for all Acura models to provide a high level of occupant protection along with injury mitigation to pedestrians, as well as increased crash compatibility with other vehicles, regardless of size or price.
Advanced safety technology
Advanced Compatibility Engineering™ (ACE™) enhances frontal collision energy management through a network of load-bearing front frame structures that increase the likelihood of two vehicles properly connecting during a collision – important if the vehicles are of different sizes with different bumper heights. As a result, the TSX’s ACE™ body structure maximizes the effectiveness of the front crumple zones as well as dispersing energy through more load-bearing channels before it reaches the passenger area. All Acura models feature the ACE™ body structure.
Inside, the TSX incorporates dual-chamber front-seat side airbags with front passenger-side Occupant Position Detection System (OPDS) and active head restraints for the front seats that are designed to reduce the likelihood of neck injury in the event of a rear collision. These features compliment a 4-channel Anti-lock Brake System (ABS) with Brake Assist, front seatbelts with automatic tensioning system and load limiters, dual-stage/multiple-threshold front airbags, side curtain airbags for all outboard seating positions and an advanced pedestrian injury mitigation design for the hood, hood hinges and windshield wiper mounts. Daytime running lights (DRL) and driver and front passenger seatbelt reminders are also standard.
Standard safety features include:
Active Safety Systems
- 4-wheel disc Anti-lock Brake System (ABS) with Electronic Brake Distribution (EBD) and Brake Assist
- Vehicle Stability Assist™ (VSA®) with traction control (Electronic Stability Control)
- Tire Pressure Monitoring System (TPMS)
Passive Safety Systems
- ACE™ body structure
- 3-point seatbelts for all seating positions

- New active front head restraints
- Head restraints for all seating positions
- Lower Anchors and Tethers for CHildren (LATCH) child car-seat attachment system located in the rear seat
ADVANCED COMPATIBILITY ENGINEERING™ (ACE™) BODY STRUCTURE
A major safety technology found on the Acura TSX is the Advanced Compatibility Engineering™ (ACE™) body structure. ACE™ makes the TSX highly effective at absorbing energy during a frontal crash while also helping to minimize the potential for "under-ride" or "over-ride" situations that may occur during head-on or offset frontal impacts with significantly larger or smaller vehicles with different bumper heights. Created using a sophisticated computer-assisted design (CAD) process, the ACE™ body structure is actually a network of integrated load-bearing elements that help attenuate impact forces by more evenly distributing them across a larger area at the front of the vehicle.
Most conventional frame designs direct frontal crash energy to the lower load-bearing structures at the front of the vehicle. Instead, the TSX’s ACE™ body structure channels frontal crash energy to both upper and lower structural areas, including the floor frame rails, side sills and A-pillars. These specially engineered energy "pathways" help distribute frontal impact forces around the passenger compartment and through a greater percentage of the vehicle’s total structure. In doing so, ACE™ helps limit cabin deformation for improved occupant protection.
Inside frame rails
Longitudinal frame rails are positioned above the floor panel rather than below it, both for aerodynamic improvements and to better withstand severe side impacts.
The 2010 TSX achieves 5-Star ratings* in all of the NHTSA governmental NCAP and SINCAP crash tests. In addition, the TSX earns "GOOD" ratings (the top rating) in all of the Insurance Institute for Highway Safety (IIHS) tests including: Frontal Offset, SICE and Headrest tests. Combined with the standard Vehicle Stability Assist™ electronic stability control system, the TSX also receives the IIHS’s TOP SAFETY PICK rating.
*Government star ratings are part of the National Highway Traffic Safety Administration’s (NHTSA’s) New Car Assessment Program (www.safercar.gov). Model tested with standard side-impact air bags (SABs).
FMVSS 301 offset rear collision
The Acura TSX meets the stringent FMVSS 301 regulation for offset rear collisions, a much more severe standard than previously used. In the new FMVSS 301 test, a 2,992 lb 1,360 kg (1,360 kg) deformable barrier strikes 70-percent of the vehicle’s width at 50 mph. In contrast, the previous FMVSS 301 used a 3,991 lb (1,814 kg) flat rigid barrier that struck the full width of the vehicle at 30 mph. The new standard requires more body energy absorption than before
VEHICLE STABILITY ASSIST™ (VSA®) WITH TRACTION CONTROL AND BRAKE ASSIST
Vehicle Stability Assist™ (VSA®) is an electronic stability control system that works together with the TSX’s Drive-by-Wire™ throttle system and 4-channel ABS system. Its purpose is to enhance overall controllability when the driver accelerates, brakes or turns suddenly. VSA® functions by independently applying brake force to one or more wheels, while also managing the throttle, ignition and fuel systems to help the vehicle maintain the driver’s intended path of travel.
In operation, VSA® continually analyzes data from seven sensors that monitor wheel and vehicle speed, steering input, lateral G forces and yaw rate, while also comparing the driver’s control inputs with the vehicle’s actual response. Whenever the vehicle’s actual response is outside of a predetermined acceptable range, VSA® intervenes with a corrective action. For example, if VSA® detects an oversteer condition (where the rear of the vehicle starts to swing wide in a corner), the system may automatically apply braking force to the outside front and rear wheels to counteract this unintended yaw motion. In the event of understeer (where the front of the vehicle "pushes" toward the outside of a turn), VSA® may apply braking to the inside front and rear wheels while reducing engine power to help return the vehicle to its intended course.
As an added benefit for performance-oriented TSX customers, VSA® also provides a limited-slip differential effect for the front wheels by applying braking force to a slipping wheel, thereby directing the driving force to the wheel with more traction.
Another key VSA® function is Brake Assist, which recognizes emergency braking situations and almost instantly applies added braking force to help the driver. This feature is controlled by a special logic in the system that determines when the brake pedal stroke and speed exceed a typical range – as they would during emergency braking. The VSA® modulator pump automatically increases braking pressure to ensure maximum stopping force, an action that helps shorten braking distance.
VSA® is calibrated to function seamlessly, and in many cases a driver will not be aware of its operation. However, anytime the system is enhancing vehicle stability, an indicator light flashes on the instrument panel. While the driver can deactivate the VSA® stability enhancement and traction-control functions via a switch on the instrument panel, ABS remains fully operational at all times.
4-CHANNEL ABS WITH ELECTRONIC BRAKE DISTRIBUTION
The TSX is equipped with an anti-lock braking system (ABS). The 4-channel/4-sensor ABS system also incorporates Electronic Brake Distribution (EBD) circuitry that automatically proportions force based on the braking force needed by each wheel.
DUAL-STAGE, DUAL-THRESHOLD FRONT AIRBAGS
Both the TSX driver and front passenger are protected by advanced front airbags that incorporate dual-stage and multiple-threshold activation technology. In the event of an airbag deployment, these two features work together to help minimize the likelihood of injuries that could sometimes be caused by the airbags themselves. In doing so, Acura’s sophisticated dual-stage, multiple-threshold system matches the airbag deployment rate to both the speed and severity of a crash. The control logic also takes several other factors into consideration, including the seating position of the driver, the weight of the front passenger, as well as whether the seat belts are in use.
For instance, during a lower-speed collision or if the seat is too close to the steering wheel, the inflators in the driver’s frontal airbag will activate sequentially (instead of simultaneously) to help reduce the initial deployment force. In a high-speed collision or if the seat is positioned farther back, both airbag igniters are triggered simultaneously for rapid inflation. The TSX’s passenger-side frontal airbag is designed to operate in a similar manner, however a sensor under the passenger seat calculates whether the weight on the lower cushion meets a minimum value specified by NHTSA. If it doesn’t, such as in the event a child is occupying the seat, the airbag is deactivated – and a light on the instrument panel indicates such a condition.
The driver’s front airbag is located in the steering wheel while the front passenger airbag is located on the top of the dashboard. When deployed, the passenger airbag inflates upward and then rearward to maximize its protective potential while reducing the likelihood of injuries being caused by the activation process.
DUAL-CHAMBER FRONT-SEAT SIDE AIRBAGS
The TSX has front-seat side airbags featuring a dual-chamber design that enhances protection for the torso and pelvis in the event of a severe side impact. Replacing the previous single-chamber airbags, the dual-chamber units have a larger upper chamber that provides improved protection for the chest area, as well as a smaller lower chamber that protects the lower-back/hip area. A single inflator unit fills both airbag chambers. Dual-chamber airbags are significantly more effective in helping minimize potential injuries caused by impacts from larger vehicles, such as a side impact involving a truck.
Full side-curtain airbags provide head protection for occupants of both the front and outboard rear seats. The airbag modules are mounted in the roof and are activated by a central sensor and sensors in the side of the TSX that-depending on crash severity- determine the most appropriate timing and deployment rates in side or other impacts depending on severity.
FRONT SEATBELTS WITH PRETENSIONERS AND LOAD LIMITERS
The TSX front seatbelts are equipped with an automatic tensioning system and load limiters to help minimize injury potential in a frontal collision. If an impact occurs, the automatic tensioning system automatically tightens the front seatbelt to help hold the occupant firmly in position. Each front seatbelt retractor also incorporates a load limiter that works in conjunction with the automatic tensioning system. The load limiter permits a small amount of controlled seatbelt slack momentarily after the automatic tensioning system is activated to limit peak restraining forces, helping to reduce the potential of serious bodily injury. The TSX’s front seatbelts also feature adjustable height shoulder anchors.
Three-point seatbelts are standard in all three rear-seating positions.
Active front head restraints
The TSX front seats feature active head restraints designed to help minimize the risk of neck injuries in the event of a rear impact. In a rear impact, the driver and front passenger’s bodies are pushed against the seatback, causing the head restraints to move forward in a carefully prescribed arc. This action helps equalize the forces transmitted to the head, neck and spine throughout the collision, a critical factor in helping to minimize potential injuries.
Adjustable rear head restraints
The Acura TSX’s rear seat features individually adjustable head restraints for all three passengers.
LOWER ANCHORS AND TETHERS FOR CHILDREN (LATCH)
Both outboard rear seating positions are fitted with Lower Anchors and Tethers for CHildren (LATCH) as standard equipment. The LATCH system provides a simple and secure method of installing up to two compatible child safety seats in the outboard seating positions.
TIRE PRESSURE MONITORING SYSTEM (TPMS)
An integrated Tire Pressure Monitoring System (TPMS) alerts the TSX driver whenever the air pressure in one or more of the vehicle’s tires decrease significantly below the recommended pressure level. Using four sensors (one in each tire), TPMS monitors and transmits information regarding tire air pressure to the TSX’s MID system. When the pressure in one or more tires drops to a significantly low level, it causes a low tire pressure indicator in the instrument cluster to illuminate.
PEDESTRIAN INJURY MITIGATION
Although there are no official standards for pedestrian injury mitigation in the event a vehicle collides with a pedestrian, the TSX has adopted several innovative safety features to help mitigate pedestrian injury. These features include a deformable hood panel – positioned high enough above the engine and other under-hood components to have space to deform – as well as deformable hood hinges and movable windshield-wiper pivots. These components help dissipate collision forces in the event of contact with a pedestrian, thereby helping to reduce the likelihood, and potential severity, of pedestrian injuries caused by the vehicle-pedestrian contact.
The TSX offers a wide array of security features including an electronic engine immobilizer to help thwart would-be thieves. Security is also advanced by the use of reinforced door lock cylinders to help deter break-ins along with protectors for the hood and trunk locks.
