The Infiniti FX is a mid-size luxury crossover SUV (E-segment in Europe) produced by the Japanese automaker Nissan under its premium brand Infiniti. It was launched in 2002 as the successor to the Infiniti QX4.
The first generation of the Infiniti FX was built on the Nissan FM platform, mainly used for vehicles such as the Nissan 370Z or the Nissan Murano. Interestingly, this platform is well suited for both rear-wheel drive and front-wheel drive cars. The Infiniti FX had no equivalent within the Nissan brand and was never sold in Japan.
As is often the case with Infiniti, its vehicles have different surnames depending on engine placement. In this case, the Infiniti FX35 and FX45 referred to its two available engines: a 3.5-liter V6 and a 4.5-liter V8, and were sold with rear-wheel drive (RWD) and all-wheel drive (AWD). In 2006, this model got a facelift with a new grille, new fenders and a revised interior.
The second generation of the Infiniti FX arrived in 2008, and lasted until 2013, when it was renamed the Infiniti QX70 to bring the model in line with the brand’s new nomenclature. The FX37 and FX30 models were sold in Europe, while in other countries the FX50 variant with a 5-liter V8 engine was the one marketed. In 2011 and 2012, this model had a variant called Infiniti FX S Limited Edition, with a refreshed exterior. Also in 2012, the Infiniti FX Sebastian Vettel Edition was launched in honor of the Formula 1 champion. Only 150 units were sold in total.
The Infiniti FX had a total of 2 generations until it was replaced by the Infiniti QX70. Among its alternatives are the Range Rover Sport, the BMW X5, the Mercedes-Benz GLE-Class, the Volvo XC90, the Lexus GX and the Porsche Cayenne.
