Audi R8 lines up as safety car for Rolex 24 at Daytona

This weekend a new era begins in American sports car racing with the Rolex 24 at Daytona to kick off the new United SportsCar Championship, the freshly inked union between the Grand Am and American Le Mans Series. There'll be a wide variety of machinery lining up on the grid at the Florida speedway, including race-ready versions of the sports cars you can drive on the road, plus Daytona Prototypes, Le Mans Prototypes and even the DeltaWing. But at the front of the pack will be the Audi R8 5.2 FSI.
That's because Ingolstadt's flagship has been named as the official safety car for this, the 52nd annual Rolex 24 at Daytona. And so the R8 becomes the first pace car pressed into service for the United SportsCar Championship, although the model also paced last year's race (pictured above) when it was under the auspices of the Grand Am series.
The car in question appears to bear little in the way of modifications over the showroom version, save for some requisite graphics and maybe some emergency lighting to make it more visible - because while you wouldn't miss an R8 slicing its way through ordinary traffic on the road, it's another story entirely in a field full of competition machinery. Audi points out that the road-going R8 shares a good 50 percent of its components with the R8 LMS competing in the race, including its 5.2-liter V10 engine that's available this year with a new seven-speed dual-clutch transmission.

Audi scores 100th LMP win

Loïc Duval, Tom Kristensen and Allan McNish took the No. 2 Audi R18 E-Tron Quattro to victory at this weekend's Six Hours of Austin at the Circuit of the Americas, marking the 12th victory for the R18 body and the 100th LMP overall victory for Audi since 2000. The milestone victory also saw a second R18, driven by Marcel Fässler, André Lotterer and Benoît Tréluyer, take third place.
Audi's LMP boss, Chris Reinke pointed out the poignancy of snagging the brand's 100th victory in the US, saying, "For Audi, it's a very special result because it was the 100th victory in LMP racing. We celebrated the first victory int he USA as well, in 2000. What could be sweeter than achieving this milestone here?" It wasn't all easy going, though, as the team was racing at COTA for the first time, and the No. 1 car had more than a few difficulties.
This victory marked the 12th for the R18 since it started racing in 2011. For comparison, the R15 TDI only managed three victories between 2009 and 2011, and the R10 TDI took 22 wins between 2006 and 2008. Those cars are overshadowed by the original Audi R8 racecar, which won 63 races between 2000 and 2006. Take a look below for the full press release from Audi, and additional quotes from team members.
