Audi manufactured a total of just 666 R8 GT Coupe and Spyder models, so you’re more likely to come across a horse on a unicycle than one of these 412 kW (560 hp) machines. Fortunately, for the crowds at last weekend’s 24 Hours Nürburgring race, a total of fourteen were in attendance. We’re not sure if any of them actually got out of first gear but, even standing still, they can still induce a dribble.
