Replacing the old QX4, the FX model was designed to reproduce the experience of driving a sports car. Being an SUV, it was a little difficult to obtain such great agility and power, thus Infiniti had to make compromises. The FX was a SUV with no off-road capabilities so that the frame would be lighter. The ride comfort was also altered, as the FX came with 20-inch alloys, race-car size brakes and a stiff suspension. The FX was based on the Nissan’s 350Z sports car platform. The extra weight of the bigger body was carried by thicker frame members. Two models were available for the 2002 model, the FX35 and the FX45. As the nameplate says, the FX35 was powered by a 3.5-liter V6 engine borrowed from the 350Z, and the FX45 was driven by a 4.5-liter V8 engine taken from the Q45 luxury sedan. Both models featured a 5-speed automatic transmission (no manual gearbox was available) and were well equipped with a dual zone climate control, traction control, stability control, brake assist and other useful features such as split folding and reclining rear seats, along with power front seats. Being in the driver’s seat would offer decent comfort and the whole interior felt a bit tighter than in the competitors’ X5 or the Range Rover. However, great visibility was offered. An optional rear-view camera was also available, to ease parking.
