New RTL videos about the R18 at Speed.com:

Personally, I'd wait for HD versions to show up on You Tube, as quality isn't great.
However, it seems that Audi may've thought about the traffic deal with the R18, as in the on track video, you'll occasionally hear an R8 LMS on the track while the R18's are going around.
