Flaunting a huge rear wing, giant air intakes, and fender-filling wheels and tires, there’s no mistaking the GT3 and GT3 RS for anything but the track-ready racers they are. Both are powered by a 500-hp 4.0-liter flat-six that howls to an 8800-rpm redline in the RS. It drives the rear wheels through a seven-speed dual-clutch automatic or, optional in the GT3, a six-speed manual. The more discreet 911 R loses the rear wing and offers the sweet-shifting six-speed manual as standard.
