As an all-new model for 2004, the QX56 receives only minor enhancements for the 2005 model year. Designated QX56 for its powerful 5.6-liter, 315-horsepower V8 engine, the QX56 adds the RearView monitor as standard equipment on all models for 2005 and active head restraints for the front passenger position.


The exterior styling of the Infiniti QX56 projects a very powerful presence, beginning with its large hood, Infiniti-style chrome "waterfall" grille and taut, barrel-shaped sides. The jewel-like xenon headlights are located low in the fenders, which, combined with the integrated halogen fog lamps, help give the QX56 a strong resemblance to the elegant front end design established by the original Infiniti QX4. The large 18-inch tires are placed close to the edge of the wheelwells, enhancing the taut, 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 exterior design also offers a long list of additional features, including chrome front door handles, dual power-adjustable heated chrome side mirrors with puddle lamps, privacy glass for the 2nd and 3rd rows and power-operated flip-out rear quarter windows. Also offered as standard equipment is a Rear Proximity Sensor (back-up obstacle warning system) in the rear bumper.

Standard for 2005, the Infiniti RearView monitor system, like that offered with the flagship Q45 sedan, utilizes 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’s opulent interior parallels Infiniti cars. 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 – and one other thing, a distinctively luxurious atmosphere.


The interior starts with 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 QX56’s instrument panel is highlighted by Fine Vision instrument illumination, 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 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).


The QX56 blends responsive acceleration with agile handling through use of its leading edge engine and chassis design. The standard 5.6-liter DOHC V8 produces 315 horsepower at 4,900 RPM and 390 lb-ft of torque at 3,600 RPM through the use of advanced design features such as aluminum block with cast iron cylinder liners, forged steel crankshaft, microfinished crankshaft and camshafts, molybdenum-coated pistons, 6-bolt main bearing caps, single-stage timing chain and, for precise control, an electronic "drive-by-wire" throttle.

Every QX56 also comes with a standard 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.

Vehicle Dynamic Control (VDC) with Active Brake Limited-Slip (ABLS) (includes deactivation switch) is also offered as standard on every QX56.

The 2005 QX56 is available in two drive configurations – rear-wheel drive ($47,750) and an all-wheel drive model ($50,750) featuring an all-wheel drive system with RWD/4H/4LO modes, 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 2005 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.
