2011 Infiniti QX56 Theater Package Navigation System Package Roof Rails Crossbars. The Infiniti QX56 was completely redesigned for 2011. Lower and wider than the outgoing truck, it's swoopier and far more eye-appealing than the previous QX SUV. The 2011 Infiniti QX56 come with 4-wheel. The Infiniti QX56 competes with the Cadillac Escalade, Lincoln Navigator, Lexus LX 570, Mercedes-Benz GL-Class, Audi Q7, and Range Rover. Some would say that all of these full-size sport-utility vehicles are outdated concepts because of their size, weight and fuel economy, but Infiniti believes the segment, which has shrunk to a third of its former self, is important. Infiniti says there are still families who need seven or eight seats and 8500-pound towing capability, and we agree. For 2011, QX56 has a completely new look, A 5.6-liter, 32-valve, double overhead-cam V8 engine, now fitted with direct fuel injection and variable valve timing and lift, produces 400 horsepower and 413 foot-pounds of torque, figures very close to the power and torque of the high-performance M56 sedan, and some 25 percent more power than the previous engine, with a 14-percent improvement in fuel economy. The QX56 powertrain for 2011 features a new 7-speed double overdrive transmission to provide first-gear acceleration for the 5600-pound truck and its cargo or trailer, and good highway fuel economy at the same time. The 7-speed automatic transmission has adaptive shifting to match each driver's driving style, with manual shift override, including a sporty throttle-blip provided on manual downshifts. The 2011 QX56 line carries plenty of electronic technology onboard to make driving safer and more enjoyable. An industry first on this SUV is the use of a tire pressure inflation indicator system. When the driver is adding air to a tire at a service station, from an aftermarket compressor or an air tank, the system honks the horn and flashes the hazard flashers when correct tire inflation pressure is reached, thus eliminating the fill-and-check, fill-and-check ritual with a tire pressure gauge. Safety equipment includes six airbags, front, side-impact and curtain, ABS brakes, traction control, yaw control. The optional all-wheel drive and the Technology Package further enhance safety as they can help the driver avoid an accident. It's in like new condition. What else can you say??
