The 2011 Infiniti QX56 has been newly redesigned with upgrades to the exterior, and a change to seating inside, as well as including more luxury to the cabin. The QX56 also comes loaded with high-tech standard features, as well as available safety features, like Intelligent Cruise Control. QX56 changes have included an increase in horsepower and improved fuel economy from its 5.6-liter V8 engine, and a new seven speed transmission.

The QX56 is also available in either two or four wheel drive configurations. Although it's no sports sedan, the 2011 QX56 does drive well for its size, the power is good, and the ride is smooth and controlled. The 5.6-liter V8 engine produces 400 horsepower and gets direct injection and a seven speed automatic transmission. Both features help it get improved fuel economy without sacrificing power. The EPA ratings for the 2011 QX56 are still considerably low, but nonetheless an improvement from the 2010 model.

The QX56 can reach an estimated 14 mpg in the city and 20 on the highway. The QX56 handles well, but there is an upgrade available to the optional Hydraulic Body Motion Control System which uses fluid filled chambers to reduce body lean. There have been considerable improvements to the exterior, but most are impressed with the interior of the 2011 QX56. Reports are stating that all rows of seats, even the third row, are comfortable, and that the cabin lives up to its luxury price tag.

There is also an improvement with the long list of high-tech features available, which all lends to the QX56's interior to be considered one of the nicest interiors in the class.
