Porsche has released a video and photo previewing the first track-only version of the new 911 (991). The 2013 Porsche 911 GT3 Cup is expected to make its official debut tomorrow.
Rumors suggest that it will have the same 450hp output as the 2012 model, but will get an updated gearbox with steering wheel-mounted paddles. The tires and hubs are borrowed from the current GT3 R, while the front of the car is made from aluminum.
