Of course, it also depends very much on the driving style. I think with the 318 i there is still a lot possible downwards if I put it on (without driving fun). But I will definitely get it in the direction of 10 liters if I am completely unreasonable. I can move my 330i x with 6, 5 or 10 liters.
Irgendein Update?
