German Car Fans posted what are likely the first spy shots of Audi's new R8 supercar, an on-again-off-again project that was just confirmed to be going full on late last year. Based on the Le Mans Quattro concept car Audi showed at the 2003 Frankfurt motor show, the R8 will reportedly be offered in V8 (400hp) and twin-turbo V10 (600hp) flavors and likely debut at the 2007 Frankfurt show.
