Maybe should be a continuation of the good thread posted by ruff on this exact topic here
My thoughts back then were. (amazingly like the long drawn out IS-F thread in a way...)

The P-C-GT is 612 hp and 3043 lb. That is sick, sick, sick (although many accounts list it weighing in closer to 3250 lb - perhaps famous P under quoting of weight...). Unless Nissan has discovered something magic about AWD that Porsche (and everybody else) knows nothing about from their extensive racing experience and heritage I am suspicious.
If the time is true then either the best guess/rumor of power or weight or both figures are off quite a bit. But damn under 7:35 is REALLY SICK.
