Vehicle Overview, , Shortly after introducing the rear-wheel-drive G35 sedan as an early 2003 model, Nissan's luxury division added a sumptuously shaped G35 Sport Coupe. Though the two body styles are related, they share no body panels. The Sport Coupe has nearly 50/50 weight distribution, and Infiniti says its suspension tuning is slightly more aggressive than the sedan's because it makes extensive use of aluminum to reduce unsprung weight., , For 2005, a 298-horsepower version of the original 3.5-liter V-6 went into manual-shift versions of both the sedan and Sport Coupe. Automatic-transmission sedans got a 20-hp boost to 280 hp, matching the output of the automatic-equipped Sport Coupe. Sedans also flaunted a redesigned exterior, a refined interior, and a new instrument panel and console., , Rear Active Steer is available on 2006 coupes, which have bi-xenon headlights and revised taillights this season. The Sport-Tuned Suspension Package for coupes features a unique front fascia and side sills. A Bluetooth-based hands-free phone system has been added to the Premium Package., , Infiniti also markets an all-wheel-drive version of the G35 sedan called the G35x. G35x, , The all-wheel-drive system on the G35x is called ATTESA E-TS (Advanced Total Traction Engineering System for All Electronic Torque Split). The system automatically transfers optimum engine torque to the appropriate wheels according to road and driving conditions. Torque distribution can range from 100 percent to the rear wheels to an even split front to rear. A Snow-Mode switch is included. Equipped with a 280-hp, 3.5-liter V-6 and a five-speed-automatic transmission, the G35x also has 17-inch alloy wheels, a tire-pressure-monitoring system and the Vehicle Dynamic Control electronic stability system,
