Infiniti FX / QX70 1st Gen FX (2003-2008)
FX35 V6 or FX45 V8 (315 hp). 'Bionic Cheetah' styling. First crossover to win comparison tests vs SUVs.
Nissan FM platform shared with G35 and 350Z. Two engines: VQ35DE 3.5L V6 (275 hp 2003-2004, 303 hp 2005+) on FX35; VK45DE 4.5L V8 (315 hp 2003-2005, 320 hp 2006+) on FX45. Five-speed Jatco JR509E automatic. RWD on FX35; AWD standard on FX45 (FX35 AWD optional). 'Bionic Cheetah' design language — coupe-profiled SUV with prominent rear haunches, set wide track. The FX was the first vehicle sold in NA with Lane Departure Warning (2005). 2006 facelift brought new grille, front bumper, wheel design, plus standard leather and rear-view camera. Production at Nissan Tochigi. The FX won numerous comparison tests at launch — Motor Trend SUV of the Year 2003. Now firmly affordable used; V8-equipped FX45 examples are the cult pick.
