SUV versus sedan drag race here. Both cars have all wheel drive and both have twin turbo powerplants. The difference being the RS6 has a larger 5.2 liter V10 motor with twin turbos (and it weighs less) versus the X6M S63 twin turbo 4.4 liter V8. The RS6 features a tune from PP-Performance said to bring it up over 700 horsepower and the Racechip tune on the X6M is stated to put it in the 590 crank horsepower range.

The X6M uses launch control and gets a nice jump from a stop showing just how potent these M SUV's are as drag racers. The RS6's power quickly takes over though and it just puts bus lengths on the X6M up top hustling to about 270 km/h or roughly 167 miles per hour.

These videos remind those of us in the USA what a shame it is that the C6 RS6 never made it to these shores.
