Audi R8 V12 TDI?

[MRR]

Sorry if this is a repost but looks like Audi's more powerful R8 will have a V12 TDI engine and not the gas V10. Jeremy Clarkson will no doubt have a crap fit

I vaguely remember hearing about this somewhere, but anyway, Diesel?! at least it's TDi!

and for now, i call shenanigans on 28 mpg.....

A V12 that produces only 500 horsepower. i was hoping for a V10 like in the RS6 avant.
Autoexpress also have the pictures of the new Rolls Royce's smaller phantom model to compete with the flying spur.

500 BHP plus 1000 nm of torque.....

Yes, but the turbos need have a boost pressure of greater than 2.5 bar to develop that amount of horsepower and torque.

where did you find that figure? In the specs of the Q7 V12?

[broken]

Sounds... Heavy.

only 500 horsepower??? most people cant even drive 120hp...trust me you can do alot with 500 babes..

Apparently they can't fit the turbocharged V10 because somehow the car catches fire.

I wonder how a big twin turbo V12 will do there...

[The_Canuck]

Hmmm with Diesel fuel as well

Most probably this engine is destined to be under the bonnet of big Audis, namely the A8 and the Q7. And maybe the R8.

Regarding the comparison with petrol engines, well the other 6 litre turbocharged engine in VAG only makes 560bhp and 650Nm so I guess this is not bad.

What is the boost pressure of said engine?

Kitdy's point was perhaps that if this engine had 2.6 bar intake charge pressure it might have more power than in its current 1.7 bar guise. I wouldnt personally entertain that idea myself.

Why not?

[jediali]

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?
