C6 RS6
E60 M5
E63 AMG
Vauxhall VXR8
Jaguar XFR
Maserati Quattroporte
So all powerful saloons in RWD/AWD. Got the car back yesterday and had a good chat with the Editor about how it all went. To sum up (from what I could gather):
M5 felt old tech with clunky gearbox
VXR8 was great fun but was all over the place
Jaguar XFR wasn't liked much
E63 was a monster and very driveable
C6 RS6 (my car) was an absolute beast and its a close run thing between it and the Merc for the favourite. The guys couldn't believe how quick mine was and how it continued to build up crazy speed all the time. Off the line was epic. In the corners started to understeer. Nothing new to any of us, but all told the C6 held its own and then some.
