Ok this will be very hard for you to understand but BMW are known to do a lot w/ so little power.... my friend's M3 w/ 215rwtq tags a long w/a 370+whp SR-T 4..... I taged a long with a 600whp+ porsche in the turns on pump gas that's only 340rwtq.

There is more that meets the eye. Like engine to tranny efficiency, tq curve and aerodynamics... In all the above the M5 chassis has proven superior by taging a long with a Gallardo. And the M5 power plant has shown that in a stock form has a lot to give, imagine when you fine tune the DME for raw power and not gas efficiency nor driveability.. add to the equation some aggresive cams and open exhaust and then you get the ultimate sedan.

By the way E60 M5 dyno at 424whp 311wtq vs a 510 car I think is ok to lose by a car...
