PERFORMANCE | 8 out of 10

Expert Quotes:

Under the hood is a 400-horsepower direct-injected version of Nissan's 5.6-liter V8…It's enough to easily get our nearly 3-ton QX up to pace with the interstate herd.
Inside Line

Still, this is not a slow truck. We tested the last QX to 60 in 7.1 seconds, and it’s shocking how something pushing three tons can get moving that quickly. The exhaust note is as glorious as before, too.
Car and Driver

Steering is nearly pinky-light. It's bit more vague than the Escalade's, and not one of the QX56's dynamic strong point.
Motor Trend

Hydraulic Body Motion Control system… is pretty effective. Body roll is, indeed, minimal, especially for such a large, comfortable SUV. And it keeps head toss down, as proven by short back-to-back drives of the new QX against an Escalade.

There's also a low range for, in theory, off-roading, but it's more likely to be used when you're pulling your boat trailer up a ramp.

Infiniti is charged with showing off the finest technology and finishes that Nissan can muster. That extends to performance as well--and when the Infiniti QX56 switched platforms and country of origin, Nissan took the opportunity to upgrade the sport-ute's powertrain and handling, adding refinement where it sorely needed it.

The full-size SUV rumbles to life as soon as its pushbutton starter is pressed. The current powerplant shares the same 5.6 liters of V-8 displacement as the old American-made version--only here, the NASCAR-tinged exhaust rumble's been swapped out for a lush, muscular engine note that's altogether more powerful and more suitable for a luxury vehicle. In its current trim, the QX56 makes a prodigious 400 horsepower and 413 pound-feet of torque, and makes the most of it by coupling it to a seven-speed automatic with almost imperceptible shifts. It's a strong, silent type of powertrain that pushes the QX56 to 60 mph in about seven seconds, according to Infiniti's estimates.

While the transmission has more gears and the engine less friction, fuel economy hasn't gone up all that much. It's EPA-rated at 14/20 mpg--better than before, okay for full-size SUVs, not so stellar in the grander scheme of things, even among luxury utes.

Since the QX56 shares some of its rugged underpinnings with the military-grade Nissan Patrol, it’s no surprise the Infiniti has off-roading in its genetic makeup.  For traction, Infiniti upgrades the rear-drive QX56 to full-time four-wheel drive with a real low drive ratio. Torque is biased to the rear, but can be split 50:50 between the front and rear axles when wheels start slipping. It’s fairly simple and effective—more so with the QX’s standard hill-start-assist electronics.

That’s not to overlook its considerable on-road talent; the independent suspension does a fine job of muting road imperfections, whether it’s shod with the base 20-inch or the brash, sexy 22-inch wheels fitted on our test machine. There’s an automatic leveling setup on the rear end for towing duty (the QX will drag 8,500 pounds behind it), as well as available Hydraulic Body Motion Control, which uses a closed air-pressure loop to damp out body lean in tight corners.

The real, though faint, difference between the suspensions didn’t get much more pronounced with larger wheels, so normally we’d advise skipping the Deluxe Touring Package and the hydraulic suspension—but since it’s added with the 22-inch wheels and other features, it’s between you and your wallet. Steering feel is too light for our tastes, but the QX’s brakes are big and powerful.



There's a pervasive luxury feel in the QX56's ride and road manners, and especially its torquey V-8.

How does the
TCC Rating work?
The TCC Rating is a clear numeric rating value based on a 10-point scale that reflects the overall opinion of our automotive experts on any vehicle and rolls up ratings we give each vehicle across sub-categories you care about like performance, safety, styling and more.

Our rating also has simple color-coded “Stop” (red), “Caution” (orange),
or “Go” (green) messages along with the numerical score so you can easily understand where we stand at a glance.

Our automotive experts then also collect and show you what other websites say about these different aspects of any vehicle. We do this leg work for you to simplify your research process.
