Remember that spate of Audi R8 prototype fires earlier this year? Well the truth has finally been revealed and it seems that Audi were testing a Lamborghini Gallardo beating R8 V10 turbo!

The prototypes were fitted with the same 433kW/580hp fitted to the Audi RS6 which would have resulted in blistering Nurburgring lap times. Unfortunately, the heat from the turbos didn’t work well with the mid-engined layout and resulted in overheating engines and as we well know, the odd fire or two.

Audi have since moved to the normally aspirated V10 and although there is no word on when it will be debuted the Detroit Auto Show in January seems likely.
