The phrase "580-HP twin-turbo V10" is hot enough to raise the temperature of any sports car enthusiast. And as sad photos of flambeed Audis have attested, without glacial cooling it's also hot enough to turn Audi RS8 test mules into fireworks.

When we first wrote about the burned out Audi R8 in the picture above, we mentioned scuttlebutt saying it was a test mule. Now, Quattro GmbH director Werner Frowein reveals that it was indeed an RS8 test mule, and that the problem was specifically due to the turbos of its V10 powerplant getting too hot in the mid-engined layout. Based on the best translation we can find of the Dutch article, Frowein says (or at least we think he says) that putting the twin-turbo V10 in the R8 is out of the question, and that they are instead working on a normally-aspirated V10 with a little more than 500 HP.
