Guide to Audi's R8
Audi's nonstop testing of various R8 models, and announcement of all kinds of plans for different powerplants, has raised all manner of confusion and conflicting claims among normal, non-Rainmen. So we've put together a guide of exactly what Audi is doing with their Porsche-fighting sportscar. Keep in mind that while it is possible to list all the different versions, it's unlikely anyone can answer "why" without just saying "competitors offer choices." That they do, but keeping it simple might be nice. So now we bring you the straight dope. For now. Until Audi changes its plans. Again. Without further Audi-do:
Current R8 – 4.2 liter V8, 420 horsepower, 317 lb ft of torque. Similar to the engine in the much-loved RS4, but dry sump in the R8.
Other models in discussion:
– 5.2 liter V10, 500+? horsepower. The engine is believed to be derived from the Lamborghini Gallardo's V10. Previously they were testing a twin turbo version akin to what's in the Audi RS6, but the prototype twin-turbo V10 car caught fire and burned to dust last year.
-6.0 liter V12 TDI, 500 horsepower, 737 lb ft of torque. This diesel supercar was in the Audi R8 Le Mans concept car from the Geneva and Detroit auto shows. And Audi just a few weeks ago confirmed that the monster oil burner will not go into production.
-4.2 liter V8 TDI, 326 hp, 550 lb ft of torque. Unlike the V12, this diesel sports car IS going into production, according to Michael Dick of Audi.

chuck: That's too logical for a car maker to comprehend...
Interesting. I can see why the 4.2 diesel V8 would see production and not the V12. Add to that, the diesel V12 would make the car too heavy and making a transmission durable enough to handle that kind of torque too costly.
Is the diesel V12 comming in any car? They've talked about putting it in the Q7 for years! This press release mentiones second half of 2008 for ordertaking. http://www.audi.de/audi/de/de2/neuwagen/q7/q7_v12tdi_quattro/news/Der_neue_Audi_Q7_V12_TDI_quattro__Der_ultimative_Performance-SUV.html
@Voice of Sweden: The V12 TDI is supposed to come in the Q7. Audi has said nothing about further vehicles for the V12 TDI, but I would not be shocked if it turned up in an A8. I do not however have any information to support this.
