Wow, what a machine. This Audi Quattro S1 at an Autocross course sounds and performs amazingly.

Nice video.
So much HP. No wonder they called them the killer Bees.

I love that sound and that had to be a lot of fun.

Ahh brings me back to the glory days of Gruppe B rally racing when WRC cars had around 800hp. haha and to think people think todays WRC cars are monsters...just tells me how old they are hehe. oh well, it's too bad they were outlawed.

man whenever i see that car it just looks like it's on the verge of being completely out of control that thing sounds like such a beast
