Video: Audi R18 racer testing at Sebring in high-def

The Audi R18 LMP1 enclosed prototype endured four days of rigorous testing at Sebring last week. Audi engineers used their time at the famed facility to test aerodynamics, fuel economy and reliability, using the R15 as a control.

You won't be able to see the R18 compete until the six-hour race in Spa-Francorchamps on May 7th, but luckily you won't have to wait that long to see the diesel-powered race car on the track.

Hit the jump to watch a two-minute clip of the R18 as it takes to Sebring like a duck takes to water. A second post-jump video is an interview with Audi Motorsport chief, Dr. Wolfgang Ullrich. The good doctor gives tells us about the R18, including how the 3.7-liter V6 diesel is all-new – a necessary step taken by Audi to conform to the sport's ever-changing rules. Next, Ullrich Baretzky, Head of Engine Development at Audi Sport, tells us that if Darth Vader had a car, "this would be his." We don't know about that, but dark side is definitely strong with the R18. Hat tip to Earwole1!
