Infiniti QX56

Research the 2012 Infiniti QX56

The Good

The 2012 Infiniti QX56 delivers luxury at every turn, with generous seating capacity, a powerful V8 engine and off-road capability, enhancing the vehicle’s overall versatility.

The Bad

The V8 engine comes at a price, in the form of poor fuel economy. Its styling is divisive; some love it, while others feel it’s showy and ostentatious. It is difficult to park and the steering is not optimally responsive.

The Bottom Line

If you want to enjoy the reliability and refinement that Infiniti is famous for in an SUV and don’t mind the low fuel economy, then look for an Infiniti QX56 for sale near you.


Two different trim packages are available: the QX56 4x2 and the QX56 4x4. Infiniti QX56 prices don’t vary a whole lot compared to other vehicles in its class, given the relatively limited selection of trim options.

MSRP: $59,200 to $62,300

Average paid: $56,127 (4x2 base model)


Acceleration and power

2012 Infiniti QX56 reviews rave about the powerful V8 engine that is capable of accelerating from 0 to 60 miles per hour in a trim 6.1 seconds. Its acceleration is all the more impressive considering the QX56’s bulky weight of about 5,850 pounds, which is a testament to the performance of the V8 engine. The QX56 has a payload of 1,664 pounds and a towing capacity of 8,500 pounds, both of which rank near the top of its class.

Handling and braking

With an independent front/rear wishbone suspension and an optional hydraulic motion control system, the QX56 provides a smooth ride with responsive handling, especially at highway speeds. Body roll is minimal, providing an even, smooth and comfortable ride.

Armed with standard anti-lock brakes, which is enhanced by a power-assist feature and Infiniti’s excellent electronic brake force distribution system, braking responsiveness is optimal. It has four-wheel disc brakes, and the vehicle’s advanced braking hydraulics creates a taut and firm feel on the brake pedal. Active-brake limited slip (ABLS) comes standard on all QX56 trim packages.



The Infiniti QX56 offers seating for up to seven passengers. The default seating material is leather, given this vehicle’s placement in the luxury class, but cloth options may also be available through your dealer. Both the third-row and second-row seats can be collapsed to increase the overall amount of cargo space in the cabin of the vehicle. The driver’s seat is 10-way adjustable, and you can upgrade the standard factory leather to a more luxurious semi-aniline material if desired.


Infiniti loaded the QX56 with standard features, including a three-zone climate control system for the front, middle and rear passenger seating areas as well as a built-in navigation system and a 13-speaker audio system with CD, DVD and MP3 player capability. Customers who upgrade to the Theater package can also enjoy a pair of monitors in the middle seating area, which are ideal for long car rides with the kids. Numerous options packages are available, including the Theater Package, Deluxe Touring Package and Technology Package if you’re looking for advanced technology features.

Cargo space

Cargo room is maximized by folding down the second- and third-row seats. The Infiniti QX56 has a maximum cargo capacity of 95.1 cubic feet, which is a little off the best-in-class score but far exceeds what you will get from most other SUVs.


Infiniti offers its patented vehicle dynamics control (VDC) system as a standard feature on all QX56 models, which provides traction control, tire pressure monitoring, power-assisted ABS braking and electronic brake force distribution. Another helpful standard safety feature is the all-way monitor, which provides external view from a comprehensive range of angles around the vehicle. As for airbags, there are plenty; each passenger seat has an airbag, and there are also front and rear side curtain airbags, dual-stage front airbags and side impact airbags in the front seats.


The 2011 Infiniti QX56 marked the debut of this vehicle, and relatively little has been changed for the 2012 model year. The only alterations to the first QX56 are in the content of the two different trim packages, with upgrades to some of the technology features. Its transmission is a smooth seven-speed configuration, unlike other vehicles in its class, and the 5.6 L V8 engine delivers slightly better fuel economy than some of its competitors.
