As many Porsche 911s as you think you might see at the golf course, yacht club or shopping mall, that's nothing compared to the legions regularly running around racing circuits worldwide. Aside from the myriad open GT grids dominated by Stuttgart machinery, the iconic German sportscar is the spec racer of choice for various national Porsche Carrera Cup championships and the Porsche Mobil1 Supercup that supports F1 races around the year. Those series use the versatile 911 GT3 Cup. With over 1,400 sold since 1998, Porsche maintains that it's the best-selling racing car of all time, and it has just announced a new model for the 2011 season onward.
Whereas the outgoing Cup racer was based on the street-going 911 GT3, the new model starts life as the harder, faster and sharper GT3 RS. That means a wider body that can accommodate bigger wheels, tires and brakes. It also carries the larger 3.8-liter flat-six with 450 horsepower – 30 more horses than the outgoing model coming from 200cc of added displacement. It also looks more like the RS, with an aggressive aero package and LED lighting for when tracks go dark and dreary.
The 2011 Porsche 911 GT3 Cup will make its track debut at the opening round of next season's Porsche Carrera Cup GB Championship, but you can delve into the details right now in the press release after the jump and in our high-res image gallery below.
