BMW M6 uses Launch Control. Revs wihout a gear up tp around 4000 rpm then when I release the shift the car launches and ... all » shifts automatically all the way up to the limit. Gas pedal is depressed all the way. Continental tyres, worn tyres and cold ground (below 8 degrees) did make the 1st gear spin until second gear. We race a standard Porsche 911 Turbo (996). This is taken place at Koenigsegg facilities in Sweden. See the full report on in the autumn of 2005. Questions to gustav@m5board
