That much power and not so much punch. They said a 60Kg lighter sedan is coming soon, anyone out there know what 60Kg is in pounds? 120? 150? I dont honestly think the performance will be any better. I am pretty sure it will come close to or match the M5's performance in the strait line but from the looks of things on the track the big E60 still has it!!! next challenge: CTS-V
