Infiniti QX

Infiniti's expanding product lineup takes a full-size step forward in spring 2004 with the addition of an all-new luxury sport utility vehicle. Designated the Infiniti QX56 for its powerful 5.6-liter V8 engine, the new full-size luxury SUV becomes the fourth V8-powered Infiniti, joining the Q45 and M45 sedans and FX45 crossover SUV, and the third to feature all-wheel drive, along with the FX and the newly introduced 2004 G35 Sport Sedan all-wheel drive model.

The new QX56, which will be the first Infiniti model assembled in North America, is designed to provide luxury on a grand scale, with eight-passenger seating (seven-passenger with 2nd row captains chairs), progressive styling, advanced technology and exceptional on-road and off-road performance.

The new 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.

The QX56's V8 is assembled at Nissan's advanced engine facility in Decherd, Tenn. 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.

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 2004 QX56 is available in two drive configurations – rear-wheel drive and an all-wheel drive model featuring a full-time 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.
