WOW, 0-60 in 3.7 seconds for a car that only weighs 45 pounds less than the M5 and has 140 less horsepower! that is pretty amazing, both cars used launch control to get their 3.7 second times.
Now immediately I thought something was wrong and I do not believe everything I read from C&D. Even their 1/4 mile times were 0.1 seconds apart.
two things the M5 has in its favor:
5-60 rolling start M5 = 4.6 sec, S6 = 4.9 sec
0-100 M5 = 8.3, S6 = 9.2
So obviously the power comes into play on the track, but not in daily traffic!
Also the braking distance on the S6 is only 157 ft, M5 is 165 ft
S6 is supposed to be priced $20K less than the M5 though!
I am a big BMW fan (obviously as I have owned several Ms and currently an X3 plus am a member of these forums) but the S6 is an amazing car/engine for the price!
Edit: Wanted to add that I am shocked that a car weighing 250 pounds more than my C63 and with 30 less horsepower and less torque can be faster! The only thing the C63 wins at is 5-60 rolling start which it is pretty amazing at, 4.2-4.3 seconds which even beats the new M5 time. Strange that there is a 1.2 second difference in the S6 launch control vs rolling start time, usually its 0.5 to 0.6 seconds on most cars.
