The 2007 Infiniti FX is available in two models, FX35 and FX45. The FX35 comes with a 275-horsepower, 3.5L V6 engine, and the FX45 gets a 320-horsepower, 4.5L DOHC V8. Both are mated to a five-speed automatic transmission with a manual shift mode and Snow-Mode function for slippery roads. The FX35 can be had with either rear-wheel drive or all-wheel drive; the FX45 comes only with all-wheel drive. The all-wheel drive system can automatically transfer more torque to the wheels with the most traction and can send up to 50 percent to the front wheels as needed. Handling and on-road performance--as opposed to off-road prowess--is emphasized in the FX. It's based on a toughened version of the FM platform that also underpins Infiniti's rear-wheel-drive performance sedans and coupes, and with the engine mounted just behind the front axle (rather than in front as in most vehicles), the FX has a near-optimal 52/48-percent weight distribution front to back. This brings more stability during quick emergency maneuvers and on curvy roads, also aided by the vehicle dynamic control (VDC) stability system, which is standard on all FX models.
