2009 Infiniti QX56 Performance

This performance review was created when the car was new. Some links may no longer point to an active page.

Thanks to its powerful V8 engine, the Infiniti QX56 has no trouble moving down the road. Reviewers are also pleasantly surprised by how well the large SUV handles.

  • "Responsive steering and a willing chassis give the QX a reasonably nimble feel in the giant-SUV segment. Quiet and luxurious on the highway." -- Car and Driver
  • "On the road the big Infiniti is surprisingly agile and easy to maneuver," while "the V8 provides plenty of pickup, with instantaneous response from the drive-by-wire throttle and a nice throaty growl from the specially-tuned exhaust." -- Kelley Blue Book

Acceleration and Power

Most reviewers agree that the Infiniti QX56 delivers impressive power and good acceleration. The 5.6-liter V8 engine makes 320 horsepower and 393 pound-torque, and is paired with a five-speed automatic transmission. Not surprisingly, fuel economy of the QX56 is poor. The Environmental Protection Agency estimates the 2WD model to get 12 mpg in the city and 18 mpg on the highway. The 4WD should get 12 mpg/17 mpg city/highway.

  • "It's no neck-snapper, but getaways and passing sprints are reasonably brisk for a big, heavy SUV." -- Consumer Guide
  • "Off-the-line acceleration is impressive." -- Motor Trend
  • The transmission "provides seamless gear changes and steps down promptly when a burst of power is needed for quick passing." -- Edmunds

Handling and Braking

For a big, heavy SUV, the QX56 handles impressively. Nevertheless, a big, heavy SUV is what the QX56 is, so reviewers' praise is tempered by the limits of the QX56's size and weight. Impressions are mixed when it comes to braking.

  • "The mammoth Infiniti is firmly planted and surprisingly nimble." -- Motor Week
  • "Body lean is noticeable when cornering, but it's nothing excessive -- just a reminder to the driver that in spite of the QX56's sure-footed handling, there are still almost 3 tons worth of luxury sport-ute getting tossed around." -- Edmunds
  • The steering is "heavy yet direct" -- Kelley Blue Book
  • "Some of our testers say the steering lacks sharp on-center feel." -- Consumer Guide
  • "The brakes tended to fade quickly during testing -- and we're not talking brake testing. They started to smoke at the end of our acceleration runs and required extensive cool-down periods, after which the space required to stop the vehicle continued to grow." -- AutoWeek
