The Infinit FX is a mid-size luxury crossover SUV. It is sold in two models: the FX35 and the FX45. Both were launched in 2003, the same time Lexus launched their GX 470. It replaced the QX4 as Infiniti’s mid-size luxury SUV, despite being larger than its predecessor.
With the FX45 crossover, Infiniti sought to combine sports-car performance with SUV functionality. The FX45′s 4.5 L V8 generates 315 hp (235 kW) and is coupled to a five-speed automatic transmission that incorporates a manual-shift mode. ATTESA E-TS All wheel drive is standard, and the FX45 has a sport-tuned four-wheel independent suspension. The FX35 uses a 3.5 L V6.
The FX series was updated for 2006 with new options and standard features. The FX35 now has leather seats, a power tilt/telescope steering wheel and a rear view camera with a color screen standard. The FX45′s V8 engine was also uprated to 320 hp (239 kW) and it gets a standard sunroof, Bluetooth system, rear view camera with a color screen, and aluminum roof rails.
