The Infiniti QX56 provides the ultimate sport utility vehicle (SUV) experience, combining the luxury appointments of an Infiniti, seating for up to eight, generous cargo and towing capacity, plus rugged off-road capability.
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 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.
The 2005 QX56 is available in two drive configurations – rear-wheel drive and an all-wheel drive model 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.
