In the year 2002, a mid size luxury crossover sport utility vehicle or SUV was created by the luxury vehicle division of the Nissan Motor Company Ltd. This was called the Infiniti FX, which was created as a replacement for the Infiniti QX4, a mid size luxury type sport utility vehicle of the Infiniti luxury brand.

                The FX is a assembled in Tochigi, Japan in 2002 but it is not sold in that country. This car has the Nissan FM platform similar to the QX56, and it follows a front engine, rear wheel drive or front engine, all wheel drive layout. The first generation FX or the S50 was produced in the years 2003 until 2008, and it is a five door sport utility vehicle with a five speed automatic and manual mode transmissions. This version received a facelift by 2006, which added new features to the car.

                By 2008, the second generation Infiniti FX or the S51 was released in the market, which is still a five door SUV, but with a seven speed automatic and manual transmission. This version of the car still follows the same layout, and it remains loyal to its profile of a “giant scarab” and “Bionic Cheetah” look. Since 2013, this car has been manufactured as the QX70.

                For the European market, a specific version called the FX37 was displayed at the Paris Motor Show in 2008 and released in October of the same year. This market was said to account for 80 percent of the FX sales.
