    Why not?

    because the w engines have cooling issues and requires significant reworking to handle higher stresses throught tighter tolerances. I wouldnt doubt it could be done, i just think it would be more beneficial to use the V10 for higher power. The golf GTI650 has a higher power version of this engine so it has been done on a conceptual design. Do you really want a 6.0 W12 boosting 1.6 bar (about 2.6 barg) and probably 800+hp?

    Yes I do, but I would rather a V12 or V10 I suppose.

    What is the difference between bar and barg?

    barg is bar gauge, as apposed to bara (bar atmosphere), and is what youd get if you put a pressure gauge in the inlet manifold or something....sorry its a common unit at work

    The Audi R10 LMP has a V12 TDI engine, I'm sure it wouldn't be too hard to de-tune the engine for use in the back of the R8 road-car - I've read that the engine cannot sustain its peak torque/bhp figures for endurance - only reliable around 700bhp, so a smaller detune would give 500-600, ideal for the R8. Plus detuning the R10 V12 TDI will be a lot cheaper than lopping off 2 cylinders.

    Do detuned LM engines often make it into low(er) end supercars? I somehow doubt there will be much in common from racing to road engines. I don't know much about this though.

    EXCELLENT MOVE Audi!

    I remembered there's a thread bout R8 and I made the comment about rather seeing a V12 TDI engine in the R8 as oppose to the rumoured-V10. Guessed they read it.

    It's an excellent decision. Bravo Audi!

    AFAIK No. I can only think of the road going 962's and those aren't exactly low end supercars.

    And I doubt the V12 engine in the R10 and the V12 unveiled in the Q7 are the same engine.

    A diesel supercar... I am excited to know how it does. Could someone enlighten me on successful diesel supercars of the past? (and perhaps send me a link to an article on it?)

    If modern diesels are anything to go by it's probably seriously lacking excitement.

    I'm not one for diesels myself, but man this just looks awesome!

    The original R8 never really appealed to me, but in this guise I can understand the hype around it. Just, dude!
