The Infiniti FX is a mid-size luxury crossover SUV sold in two models: the FX35 and the FX45. The FX replaced the QX4 as Infiniti’s mid-size luxury SUV, despite being larger than its predecessor. It was released at the same time as its competitors, the Porsche Cayenne and Volvo XC90. It shares the same platform as the Nissan 350Z, whereas the similarly-sized Nissan Murano is based on the Nissan Altima platform.
With the FX45 crossover, Infiniti sought to combine sports-car performance with SUV functionality, though the size of the platform and sloping rear end limits cargo space. The FX45’s 4.5 L V8 generates 320 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. The FX45 has a sport-tuned four-wheel independent suspension. The FX35 uses a 3.5 L V6.
TheÂ FX series was updated for 2006 with new options and standard features. The updates included leather seats, a power tilt/telescope steering wheel, and a rear view camera with a color screen. The FX45 featured additional upgrades, including a 320 hp (239 kW) V8 engine, a standard sunroof, a Bluetooth system, and aluminum roof rails. The taillights were also changed from red to clear.
