Ok, but I am trying to say that the Porsche VTG turbo might use ceramic turning vanes, which are forbiden by the ACO rules

If anyone can make it work, it's Baretzky's squad.

They have experience with VTG turbo + direct injection, alas in a diesel engine. I think this is dream combination for engine engineers. Torque over a very wide rev range, almost no turbo lag and very good fuel economy.

Has that HPD P1 engine been confirmed or was there confusion with the new P2 motor?

Mike i'd like your opinion on this one... considering that LM has always been THE track for "closed" cars, and that will always be the place where a coupè will be better than a spyder, at least on pure performance... could it be that with reduced power as in 2011 the "closed" cars could have a little bit of an advantage also on the other tracks? i heard on RLM that the very high downforce designs like, for example, the Acura ARX-02 would not be competitive at all with the new downsized engines

What difference does that make, as the ARX-02 is mothballed. The ARX-01 runs the right engine already and when equalized with the current P-1s is competitive (in the ALMS). So if it is done right it will work quite well, but there is that big word, IF. L.P. |

It has already been pointed out that the HPD engine is production based LMP2 engine: see http://www.mulsannescorner.com/RCELeMans2010.html as well. |

So let me get this straight, you think the rumored Audi V6 is going to be a production stock unit used for P-1? Or is it because their current P-1 engine is a twin turbo? If it is the latter then twin turbos are also legal on current petrol engines in P-1. L.P. |

I don't understand all your confusion.
The ACO announced in 2008 that the LMP1 will get less power engines with smaller displacement and confirmed that decision in 2009. See http://www.endurance-info.com/article.php?sid=6771 for the engine details:
According to Sam Collins the R18 "is to be fitted with a six cylinder twin turbo diesel engine, possibly mated to an energy recovery system." If this is true, obviously this will be clean sheet designed race diesel engine. It is just impossible to get 520+ bhp from a stock V6 TDI. Others have suggested that Audi will a petrol engine. I argue that then a petrol turbo engine will the preferred option. |

Especially when the TFSI system hasn't gotten much press lately as a power and effiecency boosting system which, after all, owes it origin to the TDI system.

Yes, would appear to be the case. But then these aren't the official regulations, just the latest draft: http://www.mulsannescorner.com/2011ACOVersion4.jpg |

Toss in the already extant work Peugeot did on the 908HY and this doesn't look at all surprising. |

As I said, Audi hasn't been using racing to push their TFSI gasoline technology since the R8 was retired in '06. With the R10 and R15, it's been diesel this and diesel that, and Audi has been looking into electric hybrid technology off and on for over 20 years.

Maybe Audi wants to run gas like they did at the Nordschleife with the Scirocco TSI? Could thet get that into the rule book?

So i do not see a factory Petrol-Hybrid from Peugeot, but maybe Audi. Peugeot would want to show off that Diesel-Hybrid is better than Petrol-Hybrid, and what way is better that beating them at Le Mans?. Besides the 908HY was a Diesel-Hybrid, so Peugeot already know that technology in race cars. |

What does a stock V6 TDI have to do with the R18?

Absolutely nothing, but HORNDAWG asked the following question:

I read through that whole thing between him and you and it is absolutely confusing. Horndawg seems confused, causing more confusion. And the whole thing is confusing.

I can only assume that the reporting about the HPD engine made him deeply confused http://www.motorsport.com/news/article.asp?ID=372319 has all the elements that HORNDAWG is confused about: LMP1, V6, twin turbo and production based
BTW TRuss, did Radio Le Mans pick up any rumors about the Audi and Peugeot engine for next year? Apparantly Eurosport commentators believe that petrol engines will be used. |

They may have. I didn't get to listen too much. Slightly unrelated, but I did catch the SPEED pitwall interview with Norbert Singer and that was very cool. He seemed genuinely excited about the future possibilities.
I think they will go petrol/hybrid. At least Audi anyway. It should be the easier route. The electric motors will more than make up for any lost torque that a diesel would provide. And I think that is generally easier to build a petrol engine lighter than a relative diesel. However, diesel technology in this application is still in it's infancy and is developing very rapidly, so they may go diesel. At this point it is all speculation regardless of who is reporting it. Ultimately both will chose whichever they feel the regs gives an advantage too. And that is something that is unclear to us outsiders. Or they may chose diesel/hybrid just to prove that they can do it. I wouldn't be surprised if Peugeot take this route. They sort of have that kind of attitude. No matter what...I think that this is the most exciting time in motorsports in a long while. I also think that it will prove to be one of the most important eras as well. We are witnessing the beginnings of a great change and I hope that the R18 and it's contemporaries will reflect that excitement and freshness. If the ACO can keep up, the next decade could be mind blowing. |
