Audi has already showed off the updated 2013 Audi R8, which is why this test mule has us a little perplexed. With a look somewhere between the current R8 GT and Audi's GT3 racecar, it's not really clear exactly what this car is (or will be).
Audi has been racking up motorsports wins all over the world thanks to its R8 LMS track star. The GT3 racer has compiled over 100 victories in Europe, Asia, South America and Australia. Now it's time for the four-ringed race car to earn a few checkered flags in North America, as Audi has announced that it is bringing the R8 LMS Stateside to run in the Grand-Am series.
