Motor Trend did this video of these three cars in action. Definitely worth a viewing:

How do you improve on an amazing supercar? Audi followed Lambo’s “superlegga” and Ferrari’s “Scuderia” ideals by making their V10 R8 lighter and increasing power, albiet slightly. The result is the Audi R8 GT. One-hundred pounds lighter and running a new 560hp version of it’s V10, this is a limited edition with only 333 planned to be made.

The weight savings were achieved by replacing the motorized rear spoiler for a fixed unit, more carbon-fiber panels, thinner glass, lightweight carpets and seats. With LED headlights and carbon ceramic brakes as standard, don’t expect this R8 to be cheap – it will probably push the price well into Lamborghini and Ferrari territory. Quite a feat for a German brand that doesn’t start with “P”.

This two-part video, in German, compares the two cars head-to-head, which are priced almost exactly the same in Europe:

What could you possibly do to make the R8 a better car? How about putting a 520hp V10 instead of the 420hp V8? Well here it is, and it’s coming to Canada. I snapped a shot of this white one while drooling over it at Agincourt Autohaus.

I didn’t think it was possible, but Audi improved the R8. They added a new V10 engine, some body tweaks, and standard LED lighting. The result is in the video below:
