Audi R8 TDI

With Audi winning back-to-back LeMans races in the R18 TDI Diesel powered race car, the company established that a diesel can be fast and economical. With the R8 supercar, Audi used a mantra of taking everything they learned at LeMans and putting it into a focused road-car. But why is it still running on gasoline, when Audi’s latest wins have come with the help of diesel?

The turbocharged V6 in the R18 makes 510-hp, which is a on par with the 5.2-liter V8 engine that currently lives in the R8. However it might be a little much to ask Audi to take a racing engine and put it in a road car. If Audi can manage to shoe-horn the 4.2L V8, or 6.0L V12 from the Q7 TDI, then maybe a diesel R8 could happen. The V8 diesel that Audi has makes a respectable 335-hp and a whopping 561 lb-ft of torque, while the V12 diesel makes a stunning 493-hp and a mind-blowing 738 lb-ft of torque. The R8 with a diesel engine would be the ultimate Audi flagship by using the company’s impressive Quattro all-wheel drive system, as well as the recognized TDI diesel powerplant.

Audi has showcased a R8 diesel concept, that looked simply brilliant, with a more aggressive front fascia, and a subtle rear spoiler. Just one question: why hasn’t it been made yet?
