First launched in 2004, the QX56 is the first Infiniti built in the USA, but also the most expensive one sold in North America since the Q45 was dropped. It is only available on the US market, Canada and Saudi Arabia.
The QX56 is based on the Nissan Armada SUV and shares the same F-Alpha platform with the Nissan Titan. It is a direct competitor for the Lincoln Navigator and Cadillac Escalade.
The QX56 enters the 2007 model year with minor enhancements, most notably a power increase of five horsepower (from 315 to 320) and three lb-ft of torque (from 390 to 393). A new color, Pacific Sapphire, is also offered.
For 2007 model year, the QX56 is available in two-wheel and four-wheel drive models, both equipped with a standard 5.6-liter DOHC V8 engine, 5-speed automatic transmission, Sojourner leather-appointed seating, Infiniti Navigation System, Rearview Monitor, Bluetooth Hands-Free Phone System, power-operated tailgate and an independent rear suspension (IRS) with load leveling.
Since the introduction for the 2004 model year, the QX56 has become a benchmark in class, with standard luxury features such as front Active Head Restraints, Rearview Monitor and Rear Proximity Sensor, power folding outside mirrors with heat, electro chromic auto-dimming, power adjust and integrated turn signal, Bluetooth® Hands-Free Phone System and mp3 playback capability.
“The QX56 offers the power, roominess, innovation and utility that SUV owners demand in their vehicles,” said Mark Igo, vice president and general manager, Infiniti Division. “The QX56 addresses the unmet needs in the SUV class admirably from a hardware standpoint. But it also asserts itself with tremendous luxury and style, more than with just its physical scale and capabilities.”
The eight-passenger SUV offers bold exterior styling, with a large, Infiniti-style grille, xenon headlamps and LED taillight treatment. Inside, the QX56 features a sophisticated and refined look and feel, ample 2nd row leg room, and a Bose premium audio system with 6-disc CD changer and MP3/WMA playback capabilities.
If you are looking for something new and different then the QX56 is the perfect answer for you. It provides a perfect combination of practical elegance and ergonomic thoughtfulness with a rewarding level of comfort and indulgence.
The frontal view embodies a powerful presence, beginning with its large hood, Infiniti-style chrome "waterfall" grille and taut, barrel-shaped sides. The elegant front end design continues with jewel-like xenon headlights located low in the fenders, combined with the integrated halogen fog lamps. Large 18-inch tires are placed close to the edge of the wheelwells, enhancing the athletic stance, while the standard 7-spoke chromed aluminum-alloy wheels and chrome wheel lip moldings – connected visually by the standard body side cladding and running boards – complement the QX56’s sophisticated luxury imagery.
The side view broadcasts a similar message: Infiniti-style LED tail and brake lights provide additional visual distinction. A power-operated liftgate with opening rear glass and a large bumper with integrated towing hardware (optional on 2WD) complete the rear exterior appearance.
The exterior design also offers a long list of additional features, including chrome front door handles, dual power-adjustable heated electro chromic auto-dimming chrome side mirrors with puddle lamps and integrated turn signal, privacy glass for the 2nd and 3rd rows and power-operated flip-out rear quarter windows.
Also standard is a Rear Proximity Sensor (back-up obstacle warning system) housed in the rear bumper.
This feature is aided by a standard Infiniti Rearview Monitor system, utilizing a small CCD camera discretely located in the rear license plate finisher to provide a picture of what is behind the vehicle (projected on the QX56’s standard navigation system LCD monitor).
The QX56 is big and roomy. Taking advantage of its long 123.2-inch wheelbase and manageable 206.9-inch overall length, the QX56’s designers filled the SUV’s spacious interior with a high level of roominess, comfort and convenience features, as well as a distinctively luxurious atmosphere.
The first thing that amaze you when you enter the car is the modern styling of the instrument panel, seats and storage areas and the use of first quality materials such as Sojourner leather-appointed seating surfaces and thick (16-oz.) Tuscano carpeting. Genuine Dark Macore or Blonde Apaya wood trim is used on the center console cover and steering wheel, with aluminum accents on the steering wheel trim and instrument panel finisher.
The front seats feature 10-way power adjustment for the driver and 8-way power adjustment for the passenger, while both the front and 2nd row seats are heated. The front passenger seat folds down and includes a recessed “work area.”
The standard seating configuration includes fold-flat 2nd row captain’s chairs with integrated armrests and a removable 2nd row center console. A fold-flat 2nd row bench seat is also available, providing 8-passenger seating. The QX56 also offers 2nd row leg room of 41.9 inches and large front center console storage capacity.
The 3rd row seating area, often overlooked in SUV design, treats passengers with the same high level of attention as those in the first two rows. The 3rd row seats are elevated (higher than the 2nd row) to provide a better forward view and to help facilitate easier conversation with forward occupants. The QX56 is the only vehicle in its class with standard 3rd row passenger side curtain air bag protection.
A 60/40 split fold-flat 3rd row seat is standard on the 2007 QX56. The seat’s fold-flat design provides easy operation and easy access, along with cargo hauling flexibility. In addition to ample headroom, the 3rd row provides passengers with individual side storage bins and cupholders.
There is also ample storage space behind the 3rd row seat. With the 2nd and 3rd row seats folded down, the cargo area is nearly flat. Additionally, with the front passenger seat in the folded down position, it is possible to carry long items with the rear liftgate closed.
The QX56’s instrument panel is highlighted by Fine Vision instrument illumination, a signature Infiniti analog clock, dual-zone electronically controlled climate control and a standard DVD-based navigation system with 7.0-inch LCD screen. A Bose audio system with 10 speakers, AM/FM/6-CD autochanger with mp3 playback capability and steering wheel mounted controls is standard on every QX56. The system includes dual media capability, which allows the use of radio and CD at the same time (headphones must be used to listen to second audio source). Also standard is a Bluetooth® Hands-Free Phone System. Satellite radio is offered as a factory option with choice of XM® or Sirius services.
Adjustable brake and accelerator pedals with transmission interlock and memory function are standard, part of the Auto Driving Position memory system that includes memory for pedals, outside mirrors and driver’s seat. The QX56’s full-length overhead console features individual map lights and ventilation for each passenger. The optional Infiniti DVD Mobile Entertainment System includes a flip-down console-mounted monitor, as well as storage compartments for the system’s two wireless headphones and remote controller.
Other standard interior features include four 12V power outlets, rear air conditioning with dual controls (front and rear), rear heater duct, driver and front passenger one-touch auto up/down power windows, rear auto-down power windows, 12 cupholders and bottle holders (some with capability of holding up to 64 oz. bottles), standard HomeLink® Universal Transceiver and rear area ceiling/floor-mounted cargo tie-down points and cargo net. Two interior colors are available, Willow and Graphite.
For 2007, the QX56 is powered by the standard 5.6-liter DOHC V8, but it has been revised to produce 320 horsepower at 4,900 RPM and 393 lb-ft of torque at 3,600 RPM. Nearly 90 percent of the engine’s impressive torque is available below 2,500 rpm – where it’s needed for hauling, towing or slow-speed off-road driving.
To achieve this level of power, advanced design features have been employed, such as an aluminum block with cast iron cylinder liners, forged steel crankshaft, microfinished crankshaft and camshafts, molybdenum-coated pistons, 6-bolt main bearing caps, heavy duty cooling system, single-stage timing chain and, for precise control, an electronic "drive-by-wire" throttle.
The V8 engine is mated with a 5-speed electronically controlled automatic transmission with tow/haul modes for enhanced performance and fuel efficiency. The transmission is geared specifically for use in high torque situations and includes an advanced torque converter design for improved fuel economy and an advanced powertrain management program for smooth shift quality.
A gated floor shifter provides enhanced shift control when towing. The transmission’s tow/haul mode revises the shift pattern when towing and hauling. The QX56 has a maximum towing capacity of 9,000 pounds for RWD and 8,900 pounds for 4WD (when properly equipped).
Vehicle Dynamic Control (VDC) with Active Brake Limited-Slip (ABLS) (includes deactivation switch) is also offered as standard on every QX56.
The QX56 is available in two drive configurations – rear-wheel drive and a four-wheel drive model featuring the Infiniti All-Mode 4WD system with RWD/4HI/4LO modes and an electronically controlled part-time transfer case with low gear. The two-speed electronic transfer case allows the driver to select between auto, full-time all-wheel drive and 4LO.
The QX56’s All-Mode 4WD system is designed to instantly distribute torque to all four wheels whenever road conditions warrant (up to 50 percent can go to the front wheels on demand), resulting in optimal traction. Under normal driving conditions, 4WD QX56s operate in rear-wheel drive mode. All 4WD QX56s include heavy-duty skid plates for the oil pan, fuel tank and transfer case.
The QX56 is built on a durable fully boxed, high-strength steel F-Alpha frame and features standard Dana front and rear axles. The combination of comfortable ride and responsive handling comes from the 4-wheel independent double-wishbone suspension with front and rear stabilizer bars.
An advanced rear auto-leveling air suspension is also standard on every QX56, helping provide better handling stability and ride comfort when towing or hauling cargo.
The air suspension also maintains uniform ground clearance and departure angle, even when towing or carrying cargo, by automatically adjusting the air pressure in the system’s air bladders.
“The QX56’s independent rear suspension benefits users in many ways – optimizing ride and handling on rough roads, improving ride quality for occupants in the 2nd and 3rd row seats and maximizing rear interior space through its low-profile design,” said Igo. “This is one more way that QX56 owners get the benefits of full-size SUV utility without being penalized in the areas of ride comfort and handling.”
The 2007 QX56 also features standard engine-speed-sensitive power-assisted rack-and-pinion steering, 4-wheel disc brakes with Bosch Anti-lock Braking System (ABS) with Electronic Brake force Distribution (EBD) and Brake Assist (BA), 7-spoke 18x8J chromed aluminum-alloy wheels and 265/70R18 SUV tires and Tire Pressure Monitor System (TPMS) with standard warning lamp (in gauge cluster) and warning display. A standard 28-gallon fuel tank provides an excellent driving range.
Optional is Infiniti’s advanced Intelligent Cruise Control (ICC), which allows the QX56 driver to maintain an appropriate distance from the vehicle ahead. Using a combination of laser sensors, throttle and brake actuators and the QX56’s braking system, a laser signal measures the distance to the vehicle ahead, then automatically adjusts the QX56’s speed to maintain a pre-selected following distance. (The system is not intended for congested areas or city driving and will not break the vehicle to a complete stop.)
Also available is Preview Braking. Preview Braking works side-by-side with Brake Assist. Whereas normally braking is activated only when the driver recognizes the need and moves his or her foot to activate the brake pedal, the preview function utilizes the ICC sensors to identify potential sudden braking situations and “pre-pressurizes” the Brake Assist system before the driver steps on the brake pedal. This helps maximize braking response and performance by reducing the normal brake system activation time.
The 2007 Infiniti QX56 offers an extensive list of standard safety features, including standard supplemental curtain air bags for side impact and rollover to all three rows, side-impact supplemental air bags (front seat-mounted), an Advanced Air Bag System (AABS) with dual-stage front supplemental air bags with seat belt sensors and a front passenger occupant classification sensor and front seat Active Head Restraints.
The QX56 design also includes Zone Body construction with front and rear crushable zones, 3-point front seat belts with dual pretensioners and load limiters, 3-point seat belts for all rear seat occupants (including center position) and LATCH (Lower Anchors and Tethers for Children) child seat anchor system.
Advanced Airbag System
Helping to protect all three rows of passengers, the QX56 features an array of advanced air bags. Up front, the driver and the front-passenger air bags adjust their rate of deployment based on impact severity and seat belt usage. Seat -mounted side-impact air bags move with the front seat to help maintain optimum positioning at all times. Roof-mounted curtain side-impact airbags help protects outboard occupants in all three rows during certain side collisions and rollover.
The QX56 is equipped with a sensor that can help detect an impending rollover, if one is deemed imminent; the system deploys the roof-mounted curtain side-impact air bags to help provide enhanced occupant protection.
Advanced Braking Technologies
Brake Assist helps apply maximum brake force in emergency braking situations. The available Preview function uses the Intelligent Cruise Control laser sensors to detect a rapidly slowing vehicle ahead, and then pre-pressurizes the braking system in anticipation of emergency braking.
In an evasive maneuver, holding to your steered course is paramount. If the vehicle begins to under steer or overseers, Vehicle Dynamic Control applies brake pressure to individual wheels and reduces engine output to help keep you on the track. And the Traction Control System senses wheels pin and automatically reduce engine output and breaks the spinning wheel for a surer foothold while accelerating.

Is true that the QX56 is more about luxury than sports, but this doesn’t mean it is more a crossover than a SUV. With one of the most powerful V8 engines in its class, the QX56 is the perfect choice for driving in luxurious comfort.
On the road this extra luxury and extra large SUV is smooth and quiet, even if you wouldn’t expect that from a car of its size. Featuring a four-wheel independent suspension and a smooth five-speed automatic, the QX45 is one of the most capable SUVs. You will benefit (as standard on the 2007 models) from the electronic stability control and traction control and ABS technology, both helping you to maintain control in emergency handling situations.
The first one is the Cadillac Escalade, another SUV that stands for luxury. Priced at $55.570, the Escalade is powered by a 6.2-liter V8 engine with an output of 403 hp. It also eats up to eight passengers while towing up to 7,400 pounds (the QX56 up to 9000 pounds). Offered in either 2WD or 4WD model, the Escalade features a six-speed automatic transmission with manual shift control sends the power to the pavement. Is powerful than the QX56, but is also $5000 expensive.
The second big competitor is Lincoln Navigator, another statement for luxury. The 2007 Lincoln Navigator’s distinctive design combines power and refinement to deliver Lincoln luxury. Lincoln Navigator looks powerful and capable without looking pretentious. With powerful exterior lines and impressive new interior, the 2007 Navigator has a MSRP of $45.850. Is powered by a 5.4 liter V8 engine with an output of 300 hp mated to a 6-speed automatic transmission. Compared with the QX56 is cheaper, but it has also less power.
