US vs EU
Well here is the real question. Are US EPA mpg ratings as "unreal" as EU ratings. Is the improvement BMW quotes for the M3 based solely on changing EU standards or is it indeed a true apples to apples comparison (even given that the test does not match real world driving in the first place)? I sure hope they correlate becuase the better the EPA mpg rating the car gets the less GGT we will have to pay.
