The G35 wasn't broken, but Infiniti decided to fix it anyway for 2005. Rather than needing to repair any problems, the Japanese auto maker strokes the good things to a new level of perfection on this two-year-old that already has won widespread accolades.

Performance improvements for this rear-drive, three-version sedan set hide under a sleeker, enhanced exterior, with new hood and trunk plus front and rear bumpers. Extended body color on the door sills blend into a smoother visual line. Dual circle taillights add punch, and an available rear spoiler anchors appearance and function. Inside, a redesigned instrument panel and console get real aluminum and available Rosewood trim. Sound is tweaked with Mp3 playback on the in-dash 6 CD changer for music geeks, or an available Bose premium sound system.

The G35 (and G35x all-wheel-drive version) grunts into action with authoritative 280 hp, 3.5 liter V-6 power, and 270 lb.-ft. of torque. The stick shift 6MT gets a horsepower boost to 298. Under it all, a revised, optional sport-tuned suspension rides on 18-inch tires with heftier brakes.

Plan on taking someone special in the bucket seat up front. A pair of friends in the rear get reclining seats for optimum comfort. A fifth can go along, but won't get the contoured, scooped seats of the outboard passengers. For more eye appeal and variety, Infiniti also offers these enhancements on a kicky, fully-equipped coupe in automatic and manual versions.
