About the 2009 INFINITI FX

2nd generation FX (2009-2013 as FX, later continued as QX70), first year / full redesign.

Infiniti positions the FX as a sport-focused luxury crossover rather than a traditional utility-first SUV. The core pitch is a fusion of luxury, performance, and SUV usefulness: dramatic coupe-like styling, a driver-oriented cockpit, strong on-road handling, and enough space for five people and everyday cargo. Compared with more square, comfort-first rivals, the FX is meant for shoppers who want higher seating and cargo flexibility without giving up the feel and visual drama of a performance car.

The FX35 is the core model, pairing a 303-hp V6 with leather seating, Bose audio, a rearview camera, and either rear-wheel drive or all-wheel drive. The FX50 is the performance-focused version, with a 390-hp V8, standard all-wheel drive, navigation, an Around View Monitor, climate-controlled front seats, and larger brakes.

What changed, by category

Structural

An all-new second-generation body and chassis bring a stiffer, lighter structure, a slightly longer wheelbase, a wider front track, and less aerodynamic drag.

Powertrain

Every FX receives a new 7-speed automatic. The FX35 moves to a 303-hp 3.5-liter V6, while the FX50 replaces the former FX45 and uses a new 390-hp 5.0-liter V8.

Styling

The exterior is completely redesigned, while the new cabin has a more driver-focused dashboard and a reshaped cargo area.

Safety

New driver-assistance technology joins the redesigned lineup. Equipment varies by vehicle, so shoppers should check the features fitted to a specific used FX.
