Over the past few weeks an Audi R8 prototype was snapped burning laps around the Nürburgring in Germany. The upcoming 2016 model is well into testing phase of it’s 8th production year. It’s rumoured the Supercar will come in 2 options, one being a 5 liter V10 diesel. It looks like the designers and engineers are still working out the finer details of the body work. Either way, it’s looking sleeker than ever.
