Featuring innovative technology, a new 5.0-liter V8 engine, and a fresh exterior design, the Infiniti FX50 crossover vehicle debuted in the 2009 model year as a replacement for the FX45. A 390-horsepower V8 engine powers the FX50, delivering an increase of 70 horsepower over the FX45's powerplant. The engine links to an all-new seven-speed automatic transmission, which includes specially calibrated gears that enable the FX50 to cruise at lower rpm at highway speeds, reducing fuel consumption.

The FX50's wide stance aids in stability and gives the vehicle an athletic appearance, while the front midship engine placement, which positions the engine behind the front axle but in front of the passenger cabin, helps to improve the vehicle's overall balance and handling.

Exterior design components include functional side vents, which aid in aerodynamics. In addition, a self-adjusting suspension provides improved performance as well as comfort for occupants, according to Infiniti.

Innovative features include Intelligent Cruise Control, which maintains a set distance to the car ahead at a range of speeds, and Rear Active Steering, in which the rear wheels actively turn to provide quicker, more-stable steering. A Lane Departure Prevention System monitors lane markings and applies the brakes as needed to help you stay in your lane. An Around View Monitor parking assist system uses four exterior cameras to give the driver a 360-degree view around the vehicle, displayed on an in-dash monitor.

Inside, the FX50's roomy cabin comes equipped with such features as quilted leather seats, hand-stained maple wood trim, 12 sequential welcome lights that guide occupants into the cabin, eight-way power-adjustable front seats, and an intelligent key with push-button ignition. In addition, an advanced climate control system filters out particles to remove allergens and odors from the interior air.

With the second-row seats folded, the FX50 offers 62 cubic feet of cargo space. The rear door includes a closure-assist system.
