Audi's R8 mid-engined supercar caused a stir when it was first driven back in January. The 414bhp 911 rival was warmly received by CAR's testers - and it even trumped its Porsche and Lambo rivals on our first test in the US.

However, lurking in the back of everyone's mind was the thought of the potent V10 version in the pipeline. After all, the R8 shares many components with its Gallardo brethren, so it was only a matter of time before the V10 would be dropped in. And now our spies have caught a V10 test car being put through its paces at the Nurburgring in Germany.
