some really short statements, sorry:
NS time:
C55 is not even close to M3 cornering performance due to massive understeering, but the AMG is definitely superior on the straight, great V8 engine and at last a good auto gearbox with manu-mode...
HHR:
again, understeering prevents a better lap time, also no specific handling ( weight ) some problems with brakes too....
ops:
BTW, they tested some other nice cars too, here´re some infos:
Audi RS6 Avant PLUS - HHR:
1:17.4
EVO VIII - HHR:
1:17.2
TVR Tuscan S - HHR:
1:14.9
