That would make it about 4 seconds faster than the M5 Sport Auto tested. :grrrrr:
Its not really a fair comparison to compare Sportauto time with factory time. First its different driver and second we dont know if the car is preproduction car and if it was with R-tires or not.
BMW claim the M5 does the N-ring around 8.00 min, they do not mention an exact time which mean its possible that M5 done below 8.09 min.
So if you want to compare RS6 to M5 wait til Sportauto get their hands on the new RS6 to get a "fair" comparison..
