The RS6 runs a CLS63 AMG in the first run making relatively easy work of it trapping 117.8 in the 1/4 mile. Not too fast of a trap speed which is kind of odd as in the second race the trap speed rises to 124.24 miles per hour when the RS6 runs the 1800 horsepower Gallardo. It really makes you scratch your head as to the accuracy of the timing equipment being used here in Russia and it definitely does not correlate with a typical drag strip. Regardless, the RS6 beats the Gallardo but only because the Gallardo seemed to be quite a handful and basically fell apart during its run.
The final run is against a 997.1 Turbo with bolt ons said to have 620 horsepower. This is the best and closest run of the three. The RS6 gets a lead out of hole and holds a slight advantage through the mile. This time the RS6 has a 1/4 mile trap speed of 122.771 to the 911 Turbos 124.89. The 911 Turbo loses the race due to a slower reaction time but has the quicker elapsed time and faster trap speed.
The video shows that a bolt on C6 RS6 is about a 124 mile per hour car in the 1/4 mile and that makes it pretty potent from a stop with all wheel drive. Definitely respectable, video below.
