Diesel prowess
Embargoes are like rules, they are meant to be broken. This time around Auto Motor und Sport in Germany have sent out their January issue to subscribers featuring a rendering of an Audi R8 Concept with V12 TDI engine article. The story is still under wraps by Audi until January 13 when it will make its world wide debut at the 2008 NAIAS in Detroit.
AMS calls the Audi R8 V12 TDI a study model, but depending on feedback the car might just make it to mass production (hand built mass production that is). The V12 TDI engine has made quite a name for itself on the track in the R10 race car and will be featured in the upcoming Q7 V12 TDI. It is a proven engine and will obviously not burn your R8 to a crisp.
Some numbers from the article. The Audi R8 V12 TDI produces 500 hp with 1,000 Nm of torque, 0 – 100 km/h in just 4.2 seconds, top speed lies over 300 km/h and fuel consumption is rated at 10 liters per 100 km. Disadvantage of the V12 TDI over the V8 is that the little trunk space is entirely gone due to the V12 size and it weighs 100 kg more too.
The front fascia is altered on the R8 V12 TDI because the engine requires more cooling, which is achieved through the larger airducts.
Thank you Thomas for the tip! More images at R8-quattro forum.

The characteristics of a diesel engine are no good in a sportscar. Period.
And who says that because of the concern for low fleet consumption, Audi will not bring the R8 TDI to the US anyway? I wish you fun driving it! :P
But right now I think the R8TDI is just a marketing trick to promote diesel engines in the USA! I don´t think Audi are serious about it ...

Diesel engines have different characteristics. The torque-line always has a flat portion that does not necessarily mean that it is limited (however it is possible for very high torque engines). It reaches the maximum sooner. Compare the characteristics of petrol and diesel engines at the same power. You get more torque with diesel. On the road petrol cars accelerate faster from 0 to 100 km/h for example, but diesels accelerate better on the fly (80 to 120 km/h) which is far more useful in everyday life (e. g. overtaking). Every technology has its strengths and weaknesses over the rest. If diesel engines do not fit in your image of a sports car, that does not mean, they are rubbish.
P = 2 * n * pi * M
P (Power), n (revs), M (torque)
So you see the high torque of a diesel engine is related to it´s low revs. So who wants a low rev sportscar? A race tractor? :P
I have driven a diesel (150 hp Seat TDI) for 18 month and gladly sold it. It´s a great everyday engine, but is a failure from a sports drivers point of view (high weight, not revving).
I think you don´t kown what you are talking about.... Diesel could be the sporty future! A Seat Leon 1.9TDI with 150hp is very nice. Put in a software-tuning and you we´ll see, he will beat the Golf V GTI..... I know it, because i am leading a big Seat-club and many guys have this engine in their cars....
And because you spoke about....turbo-hole? I think the last car you´ve been droven was an old Mercedes, but no actual Diesel....
Man, please be serious....

You can see that the mountain in the right of both pictures is the same and the entire back ground is the same.

Who wants a diesel engine in a sports car?
I have driven diesels, and the small usable rev range drove me mad (now I own a wankel RX-8 that revs just beautifully).
