[QUOTE=wujekwaldus;19274961]I found this somewhere in the internet:
Its Rs7 with performance package,
vs M6 Gran Coupe Competition
vs Cadillac CTS-V
vs Mercedes-AMG CLS63 S 4matic
RS7 with performance package gives 7.7s 100-200, 14.9s 100-250, this is not event close to M6 Coupe Competition(575), but faster than M6 GC CP600.
Nice results
- Better than R8 V10 Plus 1Gen... :O
I think M6 engines vary in output quite a bit. I can imagine a particular non CP car being faster than a certain CP car.
My 2014 M6 GC CP is rated at 575. According to several measurments with Insoric it puts out 611 to the wheels!
I consider the 600HP CP to be pure marketing stunt
