nope - the power loss through quattro's drivetrain is a joke compared to bmw's rwd. Also not too sure what the weight difference is.
Too true, it's about 30% loss of power through the drive train of an AWD. Where it's about 15% loss of power in a RWD car.
If it were a standing start, then yes the Audi would have smoked the :///M: but not from a rolling start. The kick a 550HP M5 has is scary !
