Yes well technically there is nothing to loose really as beating up Kolles caravan in the standings shouldn't be too big of an issue later in the season with two cars, and the distance to the factories isn't gonna change in any case. Last year the chassis survived LM with very little running so reliability shouldn't be too big of a worry either, apart from the new engine toothing issues maybe

Only time will tell, but I would suspect that they also need the time to properly test the integration of the new engine. Let's hope that it won't take too long for them to be ready to hit the track.

The interesting bit of "info" is the explicit reference to the Audi engine, besides the AER alternative.

Has anybody a clue as to how "similar" in configuration Audi's ex-DTM V8 engine is compared to Toyota's ? Could it be "easier" to accommodate the Audi engine compared to the turbocharged AER engine ?

The engines should not be too different as both are 90° V8. The dimensions are maybe different and I don't know if the mounting points at the rear bulkhead have to be changed. But it is of course a lot easier to fit a normal aspirated engine to a car which has already run such an engine. A turbo means additional intercoolers, changed cooling ducts, different airbox, different exhaust layout and so on. Take a look at the CLM P/01 engine bay and you see it. The main problem is the fixing to the monocoque and maybe length differences. If the NBE Audi V8 is shorter than the Toyota it is easy, if not it can be complicated

They are both 90 degree V8s, but I don't know about length/width/height.
The Toyota weighs around 120kg and has an aluminium block, but I believe the Audi is cast iron, so presumably is a bit heavier.

Note that the explicit reference to Audi as a possible engine supplier confirms the suspicion of last December where LesSuissesAuMans were referring to a possible engine "originating from Germany".
What a shame if they will miss the first race, but better later then never. Thank you very much for your info. !

I thought the DTM engines were LMP2 standard, not LMP1?
Or are those standards not much different?

Or did I just misread it somewhere? Wouldn't be the first time.

Naw, DTM engines have always since the relaunch in 2000 been bespoke racing engines....

Sounds like taking the Audi wouldnt be much issue, so if the article is even true, they may be going for a turbo or a bigger engine.

Has it not been obvious throughout the last season that the Toyota engine was not powerful enough , they couldn’t use the extra brakes they were given by the ACO
I remember a thread suggesting it was no more than 50BHP more than the Nissan lmp2 engine Maybe 550BHP at most, and less torque.
The Audi DTM engine would not be powerful enough either.
The only route for me it is the AER turbo. Take the extra flow rate and boost that can be got out of the ACO
I believe the ACO would let Kolles and rebellion run with +700hp at Le Mans and they would still be 5 seconds from the front.

It's a shame that after the ACO showed they were willing to give the Rebellion engine breaks that Judd didn’t propose a DI version off the 5.5l v10 for these rules

On Autosport they now say Silverstone might be a miss at least.

Also that the other options beyond Audi and AER are HPD, Judd and (yeah right) Cosworth. And it won't necessarily be announced at the ACO press conference next week.

A NA V8 engine would be the most logical choice for Rebellion Racing if time is at issue, as such choice is likely to involve less modifications to the engine installation.

BTW, Hayden refers to a Judd V10 engine. I thought Judd were only working on a 4.4L NA V8 engine and that the V10 was not the ideal choice (in terms of weight) according to Judd's own statements.

Isn't that comment like 15 months old now? Maybe they've refigured things out.

Would be neat to see.

Sure it's "old" news, but I doubt that Judd would be working both on a V8 and V10 engine without any major sale prospect, would they ?
