Porsche has unveiled the successor to the 911 GT3 Cup S, the Porsche 911 GT3 R
The new GT3 R features a 4.0-litre six-cylinder boxer engine with 480bhp (353kW), which is connected to a six-speed sequential ‘dog' gearbox.
Porsche engineers cut the car's weight to 1200kg and increased the engine size by 0.2 litres (which adds 30bhp), giving an advantage over the GT3 Cup S. The company also improved the anti-lock brakes (ABS), revised the traction control system, and added an ‘e-gas' function with throttle-blipping.
Porsche also updated the exterior with wider wheel arches, a revised front end, and LED taillights.
The 911 GT3 R is making its world debut on 14 January 2010 at the Birmingham Motor Show, and will be delivered to racing teams in spring 2010.
