Infiniti QX56
Nissan assembles the QX56, a model of sport utility vehicle, and offers it to the public under the Infiniti brand. It is based on the Nissan Armada full-size SUV, and shares the F-Alpha platform with the Nissan Titan pickup truck. The QX56 competes directly with the Lincoln Navigator and Cadillac Escalade full-size luxury sport utilities, as well as the smaller Lexus LX470.
The truck is propelled by a 5.6 L VK56DE V8 engine (315 hp [227 kW] @ 4,900 rpm and 390 ft·lbf torque @ 3,600 rpm) and a 5-speed automatic transmission with an overdrive. Each cylinder in the engine is lined with cast iron. The valvetrain is a DOHC design with four valves per cylinder. Infiniti designed the QX56's throttle responsiveness to correspond to specific drivetrain modes: when the driver selects all-wheel drive, the throttle becomes less sensitive, presumably to allow easier regulation of acceleration when off-road.
The Infiniti QX56 has around 9,000 lb. of towing capacity, which is the highest in its class. It comes in one trim level, with only key options such as: DVD entertainment system, 4WD / 2WD, and a bench instead of captain chairs as the second row. Other features which come standard are a ten-speaker Bose system, DVD-based navigation system, leather trim for all seats, dual-climate control, 18 in. chrome alloy wheels, and an adaptive cruise control system. A precrash system is a novelty in the market as well.
As with the Nissan Armada, it is built in Canton, Mississippi; and is currently only available in the American and Canadian markets. It is also the first Infiniti built in the United States. Since priced lower than the Lexus LX, the QX56 has become a success for Infiniti, outselling the Lexus LX. The upcoming Lexus JX (which replaces the Lexus LX) is expected to outperform the QX56 when it is released.
