Active Autowerke tuned X71 X6M vs E60 M5 $1000 street drag race
Here is a street race for some money between an X71 X6M and an E60 M5. The race is for money although only a $1000 which is hardly enough to even cover the modifications on the cars. The two cars race on a city street with people behind them shutting down the traffic so obviously do not try this at home. The race is from a stop and so in theory should favor the X6M with its all wheel drive against the rear wheel drive E60 M5 on street tires.
The X6M features the Active Autowerke ECU tune and also their downpipes. Since this is a money race the E60 M5 modifications are not mentioned. However, with the way the E60 M5 pulls after the launch and the way the power comes on it certainly feels like the car has nitrous. It's definitely modified whatever those modifications happen to be.
Take a look and decide for yourself:
