Now this is awkward... I never had the chance to race a 4.8i with my SD (Hartge 330hp).... But if what you are saying is true... then after all my Super Diesel might be faster than the 4.8i... since I have raced many times both my friends Cayenne S and my other 2 friends with a RR SC and won all of them every single time... and with a big difference also! and i i am talking not only 0-100 but also to speeds more than 200km....
