Audi of America recently took delivery of a U.S.-customer-spec R8 LMS Ultra meant for testing next month, and the gents at Quattroworld were able to get a picture of it. Being lighter, safer, and better balanced, the V10-powered racer with up to 570 horsepower is expected to outdo its multiple-title-winning predecessor.

It will be campaigned by APR racing in 2012. Although the stars-and-stripes outerwear doesn't look nearly as mean as just plain silver, the patriotic paint scheme could be good for shaving off a few tenths per lap when the winged coupe officially rolls out at the Grand-Am test days in January.

Head on over to Quattroworld for more details on this car and some tidbits on Audi's racing program, including the outrageous revelation offered by an Audi engineer when asked how often they had to overhaul the engines: "I don't know, we never have had to rebuild one."
