Race from 50 km/h to 250 km/h side-by-side. Filmed from within the M5 with Hartge 21' wheels. The somewhat heavier wheels is decreasing the performance in acceleration somewhat at higher speeds. The first race is with the Hartge equipped M5 with the softest EDC setting and the M5 with standard wheels has the hardest EDC setting. So the second race it is more even: both EDC settings are set to "Sport", which is the hardest setting. Analogous to if you use a bicycle with and one without shocks: the one without shocks will be easier to bike faster with. m5board.com / m6board.com Director: Gustav
