The 2008 model marks the first major revision of the Infiniti QX56 full-size luxury SUV, which burst onto the luxury SUV scene in 2004 with a number of class-leading standard features.
The QX56 continues to set the standard for luxury, performance and technology. Voted as top in its class in the J.D. Power and Associates 2006 Automotive Performance, Execution and Layout (APEAL) Study, the QX56 is enhanced for the 2008 model year with a revised exterior and interior, and new technical features.
The QX56 maintains its class-leading 2nd row roominess, go-anywhere ruggedness and the abundant power and up to 9,000-pound towing capability (when properly equipped) of the standard 320-horsepower DOHC 5.6-liter V8 engine. The 2008 QX56 is scheduled to go on sale at Infiniti retailers nationwide in spring 2007.
Infiniti engineers sought to combine the best attributes of a luxury car-like ride with exceptional cargo and passenger carrying utility. The 2008 QX56 comes standard with a 5.6-liter DOHC V8, producing 320 horsepower at 5,200 RPM and 393 lb-ft of torque at 3,400 RPM. For hauling, towing or serious off-road driving, nearly 90 percent of the engine's torque has been made available below 2,500 rpm.
Assembled at Nissan's advanced engine facility in Decherd, Tenn., the QX56's V8 incorporates advanced design features, 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.
An enhanced 5-speed electronically controlled automatic transmission is also standard, and this unique component is reinforced for the high-torque application and features unique gearing and transmission management through a variable lock-up torque converter and electronic controls for improved shifting and fuel economy.
