The X6M by courtesy of its all wheel drive gets the jump in the race. It takes a long while for the SLS AMG to run it down. The 1/4 mile time shows this as the SLS gets a poor launch running a 12.93 to the 12.66 of the X6M. So the X6M wins the 1/4 mile sprint although the trap speed shows the SLS is pulling harder at this point. The SLS runs through the 1/4 at 118.85 (VERY slow trap for an SLS) compared to the 114.41 for the X6M. Is it the cars or the timing equipment?
Regardless, the SLS eventually runs down the X6M and passes before the mile. A very impressive showing by the X6M which belongs to GermanBoost network member @Ghost. Check out the video below.
