Sometimes we just cannot get the best of both worlds i guess. Needless to say, the clutch plate diameter is surprisingly very small at 169mm (6.65") in diameter. I personally take my hat of for Porsche for introducing such technology in 2004. The clutch should not be slipped while pressing the throttle much, since this is the main reason some CGT owners are burning their clutches very frequently. I have a friend who had 3 clutches installed in less than 3000 miles of driving his car. That was very bad, especially when you consider the hefty price of the clutch + labour.
