And keeping the revs low might help the tires keep some sort of traction, leaving it up to the driver to pedal it through the first two, or maybe even three, gears. I'd really be interested to see what kind of 1/4 mile times could be had with slicks, and to see if the drive train could survive many hard launches over the course of one day. Is anyone seriously drag racing the M5? Certainly not its primary function, but I'd think there's potential there.
