From a stop once into second gear the GT-R walks away. It definitely has to be making some power to do so and increase its lead the way it does. The second run is from a roll and the M6 appears to get a slight jump. The GT-R easily makes up any distance and walks away.
M6 and M5 owners hopefully will learn from this video to not let the power go to their heads. It would be nice to see how the M6 would do versus a stock GT-R which would likely be a good race from a roll. Once tunes and bolt on's get out there for the new S63tu motor in the M5/M6, they should be monsters on the highway.
