We can't get enough of this Audi R8 V12 TDI Le Mans Concept. OK, so its not quite on the track or in showrooms just yet. And yes, it's an awfully brilliant "Brilliant Red" paint job on this oil-burning torque monster. However we imagine that when it does hit the streets with all that ground-pounding torque , the world might just spin backwards. Maybe that's why it's just sitting still for now. The globe needs time to brace itself for the impact. So much for diesels being Earth-friendly.
