Following extensive revisions for the 2008 model year, the 2010 QX56 continues to stand apart from the competition with a style all its own. Its inspired performance can be seen in its elegant exterior, tailored interior and refined appointments – and experienced in the power and strength of its standard 320-horsepower 5.6-liter V8 and responsive 4-wheel independent suspension with an auto-leveling rear design. As in previous years, the 2010 Infiniti QX is assembled in the United States and is available in two-wheel drive (2WD) or with an advanced Infiniti All-Mode 4WD® system.
The 2010 QX56 comes standard with a 5.6-liter DOHC V8 engine, 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.
The refined 5-speed electronically controlled automatic transmission 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.
A special tow/haul mode revises shift patterns when engaged and enables the QX56 to maintain a maximum towing capacity of 9,000 pounds for two-wheel drive and 8,900 pounds for four-wheel drive (when properly equipped).
Four-wheel drive (4WD) models feature the Infiniti All-Mode 4WD® system with 2WD/AUTO/4HI/4LO modes and an electronically controlled part-time transfer case with low gear, activated through an easy selection switch knob on the center stack. The 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.
