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 a near 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 goes into manual-shift versions of both the sedan and Sport Coupe. Automatic-transmission sedans get a 20-hp boost to 280 hp, matching the output of the automatic-equipped Sport Coupe. Sedans also have a redesigned exterior, a refined interior, and a new instrument panel and console. The sedan's Sport-Tuned Suspension Package adds 18-inch tires and a viscous limited-slip differential. Coupes with this package ride on new 19-inch forged alloy wheels., , Exterior, , The G35 features short front and rear overhangs. The 2005 redesign includes a new hood, trunk, bumpers, body-colored side sills and dual-circle LED taillamps. The aerodynamically styled G35 Sport Coupe rides on the same 112.2-inch wheelbase as the sedan but is 4.3 inches shorter and 3 inches lower., , , Interior, , Leather upholstery is standard in the G35 sedan's five-passenger interior, which features a tilting gauge cluster and an in-dash six-CD changer. The sedan's available Premium Packages include dual-zone climate control, driver's seat memory and a Bose audio system. The sedan's trunk holds 14.8 cubic feet of cargo, and the coupe's trunk volume is 7.8 cubic feet., , Up to four occupants can fit inside the Sport Coupe, which features a sculpted fold-down rear seat. Options include a DVD-based navigation system, XM Satellite Radio and Sirius Satellite Radio., , , Under the Hood, , In G35s equipped with a five-speed-automatic transmission, the 3.5-liter V-6 develops 280 hp and 270 pounds-feet of torque. The five-speed automatic incorporates a manual-shift provision. When a six-speed-manual transmission is installed, engine output is 298 hp and 260 pounds-feet of torque., , , Safety, , Dual-stage front airbags, front-seat side-impact airbags and side curtain-type airbags are standard. All-disc antilock brakes include brake assist and electronic brake-force distribution. Infiniti's Vehicle Dynamic Control electronic stability system is standard., , , Driving Impressions, , The G35 sport sedan takes curves beautifully. Body roll is minimal, and the engine's power helps when heading through quick turns. With both the regular suspension and the tauter setup, the ride is surprisingly smooth on most surfaces. Because the base model is so stable and flat, differences with the sport suspension aren't dramatic. Engine noise is definitely noticeable, but it's not unpleasant., , The G35 Sport Coupe is sporty in both appearance and feel. It has plenty of power and operates with stunning precision and stability. Even though its suspension is taut, the ride is surprisingly smooth, but jolts inevitably occur on rougher surfaces. An automatic-transmission model is nearly as satisfying as one with the manual transmission. The driver's seat is comfortably snug, but front headroom with the sunroof could be better.
