About the 2013 INFINITI FX

2nd generation FX (all-new for 2009; 2013 is the last model year before the FX name changes to QX70 for 2014).

Infiniti positions the FX as an “iconic performance crossover” that blends luxury-car features with a sporty, coupe-like shape and strong engines. More than many midsize luxury SUVs of its time, the FX is about style, quick responses, and a driver-focused cabin rather than maximum cargo room or family duty. Buyers picked it for its dramatic look, strong V6 or V8 power, and more athletic road manners than softer rivals.

The FX37 is the core model, pairing its 325-hp V6 with heated leather front seats, a power moonroof, and a power liftgate. The FX37 Limited Edition adds AWD, navigation, 21-inch wheels, and extra camera technology, while the FX50 sits at the top with a 390-hp V8, standard AWD, and heated and ventilated quilted-leather front seats.
