Racing model carries over from the last 911 with some key upgrades to keep it at the front of the pack.
Show up at any GT race and you're bound to see a bunch of 911s competing. Last year alone, the 911 GT3 R – just one of numerous racing versions Porsche offers – fielded by private customer racing teams competed in 131 races and won 41 of them. The GT3 R was introduced in 2010, and while there's a new 911 on the road already, Porsche is sticking with the old model for the racetrack, giving it a series of upgrades for the 2013 racing season.
While the 4.0-liter flat-six carries over unchanged at 500 horsepower, the track is now two inches wider to incorporate wider wheels, the wheelbase has been stretched by half an inch, and the aero kit gains a massive new rear wing, a new diffuser and enhanced bodywork to fit over the larger footprint. Porsche hasn't revealed pricing for a new GT3 R, but has indicated that teams can upgrade their existing cars for 45,500 euros.
