Infiniti launched the mid-size luxury crossover SUV FX for the first time in 2003. The FX replaced the QX4 and is built on the same platform as the Nissan 350Z.
Infiniti’s breakthrough FX Crossover SUV offers a unique combination of aggressive styling, outstanding performance and luxury car comfort. The FX was conceived on the theme of a "Bionic Cheetah," utilizing advanced technology to create one of the best performing premium crossover SUVs ever imagined.

The FX is available in two different versions: the FX35 and the FX45, where the 35 and the 45 nameplates refer to the two different engines. The FX35 available in two trims, the 2WD and the AWD both are fitted to a dual overhead cam 3.5-liter 24-valve V6 VQ35DE gasoline engine, with aluminum-alloy block and heads and low-friction molybdenum-coated pistons that takes use of the Continuous variable valve timing which in part optimizes the opening of intake valves.
