Audi surprised the motoring world when they put the Le Mans Quattro concept in production in the form the R8. Audi's mid-engined sports car is bordering on supercar territory thanks to its 5.2 liter V10 engine. Handling shouldn't be a problem too as it sends power to all four wheels via Quattro all wheel drive. This being an Audi you can expect a quiet and refined driving experience when you're at more docile speeds. The everyday supercar? That's the R8.
