I don't notice the weight difference from full to a 1/4 tank, in this car. However, I have no doubt that a lighter M3 is faster, more agile, and has better fuel economy.
Has anyone done a 1/4 mile run with a full tank vs an empty tank back to back?

One guy tried but he ran out of gas at the 3/16 of a mile mark.
