What you have here is Audi latest LeMans-crushing R15 TDI accompanied by an R8 GT3 on the left and a mystery R8 on the right. The big news about the new R15 TDI are its power figures: 600 hp and 774 lb-ft of torque from a V10 diesel. Those paying close attention will have noticed that this is two less cylinders than the R10 that the R15 is replacing. Despite this, the R15 is more powerful and lighter.
