Truely ridiculous!
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).

Why not? Just take a look at TDI engines of BMW and Mercedes's sporty cars. Everything is possible.What will you be driving when the all the fuel on the earth runs out? An electrical or hydrogen powered car?

Ridiculous?...look at their R10 racecar, doesn't it have a diesel engine?..and yet it is one of the best race cars ever made!..come on man, it's not all about petrol anymore. Have you ever heard the engine of an Audi Q7 3.0 TDI V6?..or have you ever experienced the true power such an engine delivers?..I rest my case.

Have you ever had to accelerate with a Diesel engine? First you have the Turbo-hole, then you have to shift every second because above 4000 revs, it feels like hitting a wall! Diesels may be nice for passenger cars, but shity for sportscars ...

Believe me, when it comes to Audi's, Turbo lag is very well regulated, and barely noticeable. If diesel is shitty for sports cars, the Audi R10 would not be amongst the best racing cars ever made :).

Just like Ferrari or mclaren adapt their racing technologies into their road cars, Audi will do the same.

The LeMans R8 Diesel was only successful, because a Diesel provides from it????s layout the best power/consumption ratio. Diesels are the most efficient engines, that I do not doubt! And no doubt you can adapt your drivingstyle to be quick in a diesel, but still it is no fun doing so!
The characteristics of a diesel engine are no good in a sportscar. Period.

I will have to disagree with you yet again. Anyway...you have your opinion and I have mine :P...i'm gna stop contradicting you coz this is gna end up being an argument lol

Herr Bugno's sentiments on diesels are the exact reason that we'll never see such an amazing car on this side of the pond. Shame, really!!

Hey, don????t blame me! ;-) And it????s not sentiments, its experience.
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 ...

Audi seem to think the torque is too much anyway, so they limit it: http://www.schwab-kolb.com/JPG/AUDI/Audi0299.JPG

Herr.Bugno,
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.
