But we were/are afraid of turbines....

So, the disadvantage is teorically enough to force Audi only fight for 5ยบ place?

Agreed Audi will throw everything they can at the 24 hour and they will be hard to beat whatever they are saying now

Hmm... I detect the burnt smell of martyrdom. Audi will still be the team to beat.

Audi definitely still has the efficiency advantage, the rules are equalising different fuel technology but they definitely leave a little advantage, IMHO completely equal FTF would be around 1.1 not 1.07.
As for ERS initiative after testing it obviously showed that the first numbers for recuperation efficiency were too optimistic and that in actual race driving you can not get that much energy back. The Porsche decision to go from 8MJ to 6MJ class proves that. |

I am a lot more pessimistic for Audi. I suspect that the ERS incentive is still in place, potentially giving Toyota and Porsche a 2 sec performance advantage for free.
On top of that, Audi will have a disadvantage in stint length. In the shorter WEC races, this could mean that Audi has to do a late splash and dash to finish the race. I hope that I am wrong, but my prediction is still that Toyota will dominate Silverstone and Spa, clearly showing that the rules favor them. And because the EoT only allows for rule changes after Le Mans, Toyota will win Le Mans with little effort. Last edited by gwyllion; 17 Apr 2014 at 07:47. |

The big question mark is stint length. It indeed seems that Audi's stints at LM will possibly be one lap shorter than the competition. This stint-length deficit obviously translates into a performance deficit, but this deficit was already pretty obvious in the initial drafts of the rules. I am therefore still a bit surprised to hear Audi "complain" about this stint-length deficit. |

Confucius says: Never ever underestimate the mighty diesel!
(The whole 2 MJ thing was very carefully planned and it is going to be extremely well executed. They may even chose to lose the first two races and make everyone believe even more in them being so badly hurt by the rules, then come back at LeMans and surprise everyone with some "new found speed" and by the time everyone realizes what is going on, the one race that matters will be in their pocket. Watch them execute, this is going to be a master piece on so many levels! ) |

We also know that Audi may have the edge over their opposition in terms of areo. They've done most of their testing (that we know of) in some kind of sprint race configuration. Audi by far have the most miles of problem-free testing, and the most miles of testing by far of a sprint race configuration.
Their sector times at the PR test, especially if they were running to the newest energy allocation basis, were impressive in spite of all that drag. And they still have the power and torque of the diesel engine, and in race conditions, that matters quite a lot, as the DP vs LMP2 deal in TUSCC has shown. Also, it's easier to recover the 2MJ equivalent around Silverstone than 6MJ equivalent--traffic and track conditions can really screw that up for Porsche and Toyota. And there will be times that the hybrid systems on all cars will be of limited use. Also, the diesel engine is more efficient than a gasoline engine running on E20, and the B10 diesel oil has more energy per unit than E20. In spite of my seemingly gloom and doom predictions, based on the PR test (and yes, it was only a test), I don't think that Audi are down and out for here or LM just yet. If they can be faster than Toyota and Porsche and hit their energy targets, they'll be in fairly good shape come Sunday. |

I always thougt it was the Toyota car that had better aerodynamics

I'm with gwyllion on the fate of Audi, firmer than ever after the calculation of stint distances and the EoT figures. They surely cannot win anything before Le Mans, podium finishes as a reward for their teamwork and experience I'd say.

Guys never ever count Audi out, in the end they are always somewhere up there where the prices are given.

Audi have been doing this type of racing for many years now they have a great team with bags of experience so never underestimate them

What unit? All the units are calculated in MJ. And E20 can potentially bring more efficiency (higher CR) than E10 or premium gasoline, but it has less energy per volume.

It also has to be remembered that Audi have run B10 since 2008, while E20 is new to both Porsche and Toyota for this season. |

Ethanol has a higher octane number than petrol. Therefor the engine can run with a higher compression ratio, leading to a power increase. The fact that the fuel consumption is higher for ethanol, can easily be compensated in the rules with a higher fuel flow and bigger fuel tank. |

Audi has to be having some amazing corning speeds to be very close to Porsche in lap time at Silverstone but down almost 35km/h down the straights.

the last minute rule change seems quite unfair to audi, on the other hand, looking at their track performance so far, i think maybe they can predict their performance and efficiency better than us and since they didn't decide to quit or make a huge thing out of it, i suppose they feel they have what it takes to fight for victory. i mean, if the rules would have been so catastrophic on their performance, they wouldn't really accept fighting for anything less than victory in wec races and, even moreso, in le mans, would they?
