The Infiniti FX was a mid-size luxury crossover SUV produced by Nissan's premium division, Infiniti. It was first introduced in 2002 as a 2003 model and went through three generations until it was discontinued in 2014.
First Generation (2002-2008)
The first-generation FX, also known as the QX56 in some markets, was based on the Nissan FM platform and shared its underpinnings with the Infiniti M35 and G35. The vehicle featured a sporty design with a sloping roofline, large wheels, and a distinctive front grille. It came with a 3.5-liter V6 engine producing 280 horsepower in most markets, but in some countries, it was available with a more powerful 4.5-liter V8 engine.
The FX was initially offered in two trim levels: the base model and the more luxurious GT-P package. The latter added features such as leather upholstery, a moonroof, and an upgraded audio system. During its production run, the first-generation FX underwent several minor updates, including the addition of a third-row seat for some trim levels.
Second Generation (2008-2012)
The second-generation Infiniti FX was unveiled at the 2007 Los Angeles Auto Show as a 2008 model. This iteration featured a more aggressive and aerodynamic design, with larger exterior dimensions compared to its predecessor. The new chassis also provided improved stability and comfort.
Under the hood, the FX continued to use a 3.5-liter V6 engine but now produced 303 horsepower. A hybrid version was also introduced in some markets, featuring a 2.7-liter inline-six engine paired with an electric motor for increased fuel efficiency. This second-generation FX came in three trim levels: Base, Sport, and GT.
Third Generation (2012-2014)
The third and final generation of the Infiniti FX was launched at the 2011 Detroit Auto Show as a 2013 model. It boasted a more conservative yet elegant design compared to its predecessors. This iteration measured larger in every dimension than the previous one, and it continued to use the same powertrain options.
During this period, the FX underwent several updates, including changes to the front bumper and grille for improved aerodynamics. However, despite being updated with new technologies such as Infiniti's Around View Monitor (AVM), which provided a 360-degree view of its surroundings, sales declined steadily over the years due to increased competition in the luxury SUV segment.
Discontinuation and Legacy
The FX was discontinued at the end of the 2014 model year. Despite being known for its sporty design and decent performance, it struggled to compete with other offerings from competitors like BMW's X5, Mercedes-Benz's GLE-Class, and Audi's Q7.
However, during its production run, the Infiniti FX gained a reputation as one of the more stylish options in its segment. Its legacy can be seen in the design cues that have been carried over to newer models such as the QX50, which shares some visual similarities with its predecessor.
