I accidently watched this video from GRIP and I could'nt find it here although it's actually quite old.
I thought that I post it here because it's definitely worth watching.

First vid is a bit silly because he's driving against a rocket and an arrow (with a speed of 350 km/h).
But the second video is very interesting with a scared Matthias Malmedie and the run for 400 km/h (The tires are only allowed up to 350 km/h)
