The R8 V12 TDI will be produced to numbers, and you will see it again. Dont worry

The basis for that? Audi's representatives at Le Mans seemed to be saying this was highly unlikely........ |

But then a gain approperly built petrol engine can do the same. My 348 ci, 5.7 L V8 runs 405 RWHP ( about 450 bhp ) and 407 lb ft or RWTQ. Friend of mine has 383 ci SBC with 585 RWHP ( 660 BHP) and 640 lb ft of RWTQ Granted the diesels fuel millage might be better then our 4 mpg under race conditions. My diesel pick up has 6.6 l V8 with 365 bhp and 640 lb ft of Torque. and gets 15-17 mpg. Under a race condition, dont think it would get more then 4-5 mpg either My 5.7 l in stock condition on the highway would get 30-32 mpg. Would a diesel provide any real benefit ?

Maybe, its all give and take, the slower engine speed of a Diesel would help reliabilty I would have thought, but the higher stresses on the transmission could outweigh that.
I think a diesel should show better MPG under racing than a petrol version IMHO. I guess we will not know until someone puts one on the track, until then its all ********!! BTW. I dont think Audi will be the first to do that either. |

Only if it was Bio-diesel. Dont know what the difference would be otherwise because there is always bio-ethanol for the petrol engines too. So any techie out there explain the mileage differential between the two bio fuels?

The other thing to consider, in racing terms at least, diesel is a new fuel and is on an upward curve, as more people come on board the progress will be faster I think.

The Audi R8 V12 TDI will, if raced, be a BTL engine, second generation biodiesel, as the engine is designed for that fuel to be used at Le Mans. Previously, until Le Mans this year the R10 ran on GTL fuel (gas-to-liquid), which is based on natural gas.
BTL (biomass-to-liquid) was introduced at the 2008 Le Mans, although mixed into the GTL fuel. BTL is based on waste biomass and not food sources, such as waste wood. BTL promises a reduction in the amount of CO2 emission by almost 90 per cent compared to traditional diesel. Last edited by Aslak Vind; 3 Aug 2008 at 16:33. |

Bio-Diesel is about 50% the fuel milage and cant accelerate ( torque ) worth anything. In trucks. Cars are very slow off the line too. ON Street / road going cars. Bio-fuel ( ethonalbased ) provides about 65-70% of the fuel millage of petrol. IF event that good. Cost of production, is about the same or slightly more do to high government subsidies The BIGGEST down fall of any bio fuels is the switch of food production to fuel production so food prices skyrocket |

Where did you get the info about biodiesel giving you less power and fuel economy, from what I know it lowers fuel economy very little while having no effect on power. Lack of standards (and uniform quality) is why VW only warranties 5% biodiesel. |

Lots of ppl around here have tried the bio-deisel in their older trucks, only to pump it out and put dino deisel back in. Now many of the stations that have bio-diesel cant sell too much of it. Only the greenie beanies want and buy the stuff. Bio -Diesel #3 has certain standards which must be meet inorder to be sold. |

EPA says 10% lower power and fuel economy for 100% biodiesel. So it shouldn't be a huge problem, I think it wouldn't be impossible for Shell to make biodiesel for racing that improves upon the 10% figure.

I have seen those figures as well. But dont think that 10% is close. City of Raleigh has many flex fuel cars. Milage reported is about 18% less, fuel costs are only slightly less but engine maintenance is up quite a bit.
Valves and rings need replacing at 50-60,000 miles. were on petrol there would not be a need. |

Flex fuel is completely different from biodiesel, E85 can drop fuel economy 25-30%+. That's because it just has less energy per gallon.

Likely a new customer in 2009 for the GT4 class: the former Peugeot RC Cup(known at the 2000 Paris Motorshow as "RC Carreau") !!!
