Let me say upfront that the B6, M6 and M6 GC are all great cars and I don't have a dog in the fight. I'm guessing weight will play a major factor as to which one is faster. The M6 is approximately 525 lbs less than the B6, while the M6 GC is approximately 350 less than the B6. The weight difference will affect both speed in a drag race and handling overall.

Having said all of that, the Audi RS7 is substantially faster off the line and for a quarter mile than the M6 GC. Does that mean another AWD tuned monster like the B6 would beat another monster, the M6 2-door coupe, in drag race? Who knows. The RS7 is 350 lbs lighter and has 20 more HP than the B6, but the B6 has slightly more lbs/ft of torque (24) than the RS7. Since M6 coupe is lighter than RS7 and has the same HP, but no AWD, it seems that it would be an interesting drag race b/w a B6 and M6 coupe. Here is a video of the RS7 vs. M6 GC for those of you who haven't seen this race.
