What's the point of racing from a roll if you force both cars into 3rd gear? Both transmissions are geared differently, especially since the BMW has an 8-speed and Benz has a 9-speed. I'm not looking it up but most likely the Benz has a deeper 3rd gear as a result, but either way, forcing both cars into 3rd is not representative of actual street driving.

If you want to see who would actually win "from a roll", the test is simple - you both just floor it and see what happens. The transmissions will kick down to whatever gear is appropriate, and whoever wins wins.
