Back at the Detroit Auto Show, Audi revealed their V12 TDI R8, a concept that celebrated Audi’s continued success with the alternative fuel in prototype racing with the R10 and now R15 endurance racers. The TDI concept also served as a preview for the future turbo diesel supercar. But due to the current economic situation, it doesn’t look like Audi will be taking any risks in the near future.

The Audi R8 V12 TDI concept is powered by a 5.5 Liter turbo diesel engine inspired by their original diesel racecar, the R10. The engine in the R8 concept produces a max output of 500 HP and a peak torque of almost 740 lb-ft. The concept could sprint to 60 MPH in only 4.2 seconds.

An Audi insider said that engineering a production version involved modifying the chassis in order to accommodate the V12 TDI power plant as opposed to the standard model, a cost that would be too expensive to pass along to the consumer.

This model is equipped with a 4.2 litre V8 internal combustion engine. It also uses a 5.2 litre FSI internal combustion engine.

diesel for r8? i guess it was not a good idea because diesel engines are loud and emits a lot of carbon and vibration.

quite good, IMO audi’s r8 will lose it’s reputation when they make the r8 TDI. R8 engines are great specially when it uses a high octane petrols.

Thats just Audi being cheap, as usual. This current car is based on a Gallardo platform and the engine is the one used in the A4 and it has a base price of 120K. The gearbox is also borrowed from the gallardo. What exactly is the cost of chassis modifications when your car borrows just about everything from other cars?

Just like the Germans to be stringy. Its a wonder they sell crap at such high prices and get away with it.

I heard from a friend of mine that vehicles that run on diesel is not as fast as gasoline. So how would you race you R8 with a diesel. The performance of the car would surely be compromised.

it just doesn’t go right. its completely incompatible.

If keeping the V12 TDI diesel engine would involved modifying the chassis that would cost too expensive and in the end they will pass to the consumer, better not continue the production.

This is sad.. but they are kinda doesn’t make sense to make this if they cant sell enough units..I mean who really would go out and buy an R8 diesel (and I am talking about people that can afford a gasoline R8 because the diesel will most likely cost more)

That is a right move for Audi although this race car is most anticipated in the track, we know we can’t risk more in this period of recession especially the stakeholders.
