Quote:there is no rolling resistance on the track itself so it's probably something else as well.
With RollResistanceCoefficient = 1.0 you have asphalt rolling resistance. The old code omits the multiplication with tire normal force resulting in a very low rolling resistance. The F1 generates a lot of downforce increasing normal force/rolling resistance with velocity. It still shouldn't top out at 130mph. I guess the quadratic rolling resistance coefficient of the tires is too high, haven't checked the numbers though.
