But today, we received the most definitive proof yet; engine-bay shots and a video of a white prototype shot in Florida. According to members of AudiWorld, a few V10 mules have been handed out to current, and supposedly trustworthy, R8 owners for evaluation, sporting oval exhaust pipes and a revised fascia. While that's a rather unconventional move on Audi's part, it's proof that the automaker is getting ready to launch the new RS8 (or R10) in the near future.
Looks like the many rumors of Audi preparing a V-10 version of its phenomenal R8 super car are turning out to be very true. One of the Jalopnik deep-cover agents has uncovered these convincing photos, which show, along with slight revisions elsewhere, a two extra cylinders packed into the engine bay. If earlier reports are correct that V-10 should displace 5.2-liters and produce something like 520 horsepower.
