Porsche is apparently readying some significant changes to its street-legal race car, the GT3. According to a forum member on Rennlist, the next-generation (991) version of the GT3 will adopt a larger engine, a dual-clutch gearbox and several even more significant changes.
The poster, who goes by the screen name 'rosenbergendo' says he received the information from a Porsche Motorsport exec while attending the recent Daytona 24 Hour race.
According to his unnamed source, the 991 GT3 will get a 480-hp motor (up 45-hp) from a larger 4.0-liter flat-six. It will also offer an optional PDK dual-clutch transmission, which is referred to as PDK-S. Apparently Porsche has been reluctant to include a dual-clutch unit in the GT3, not only because it's a 'purists car' but because the PDK setup is too heavy. This new PDK-S unit, however, will solve much of the weight concern.
More significant changes are also in store with a projected weight loss of 180-200 lbs thanks to the use of composite materials, while the engine will be moved slightly forward in the chassis, essentially making it a mid-engine car and significantly improving the car's balance.
