This is with the Megane cars that I notice so far. I have yet to try the other cars. When I do a set up and the laps in the setup is set to 24. During the race most playing were all able to do 30 laps on the same amount of fuel for 24 laps in a race. That is a 6 lap difference. Is this normal? I understand that a few laps over with conserving gas but 6 laps seems a bit high.
