Vehicle Overview

The original Infiniti FX explored the boundaries of sportiness in an SUV, though not without some drawbacks in utility. A 390-horsepower V-8 powers the FX50, while a 303-hp V-6 powers the FX35, which is covered in a separate report in the Cars.com Research section. A number of luxury SUVs, from the Lexus RX 350 to the Mercedes M-Class, compete with the FX. All-wheel drive is standard on the FX50.

New for 2011
A power liftgate will become standard later in the model year, and black lacquer interior trim replaces maple accents as standard on the FX50.

Exterior
The FX's beady headlights and snout-nosed grille are at least as controversial as those elements on its predecessor if not more so. Along the side, functional air vents reduce the FX's lift, Infiniti says. Exterior features include:

  • Standard 20-inch alloy wheels
  • Available 21-inch alloy wheels
  • Standard bi-xenon headlights
  • Optional adaptive suspension continuously reacts to changing road conditions
  • Optional Rear Active Steer angles rear wheels slightly to enhance turning precision

Interior
The cabin has a high dashboard. A ledge just below the windshield curls around to the window sills, and air-conditioning and stereo controls sit below an available navigation display.

  • 3,500-pound towing capacity

Safety
Standard safety features include active head restraints, side-impact airbags for the front seats and side curtain airbags for both rows.
