At a Glance: 2007 INFINITI QX56

The powerful INFINITI QX56 full-size sport utility vehicle, which was ranked top in its class in the J.D. Power and Associates 2006 Automotive Performance, Execution and Layout (APEAL) Study, has been enhanced for the 2007 model year with increased horsepower and torque from its standard DOHC 5.6-litre V8 engine. Power has increased 5 horsepower (from 315 to 320) and torque increased by 3 lb-ft (from 390 to 393). A new colour, Midnight Blue, is also new for 2007.

Unchanged is the QX56’s interior roominess with seating for up to eight and maximum utility with generous cargo, excellent towing capacity and rugged off-road capability. The vehicle’s extensive list of standard technology and convenience features remains one of the best in the premium SUV arena.
