Actually the M6 weighs 3770 pounds according to wiki and I believe car and driver. A delta of 120 pounds to the M3.
The M6 is often mistakenly confused for the M5 which is over 4000 pounds. You can feel the difference between an M5 and M6 on the track...
It is misleading to say the M6 is really heavy (relative to the M3).
Look up the internet. The SportAuto running of the M6 time of 8:09 was done with the speed limiter.
