IMSA chooses to keep its pond small so the overly self-conscious fish stay safe and happy. And I don't want ACO to do the same.

ACO ... Oreca, Ligier, Norma/Duqueine

Totally differently but also totally the same

[Pandamasque]

Very recent history teaches us that one these approaches gives us ALMS and the other gives us... GrandAm *sad trombone*.

The fact that such a legendary event as 24 Hours of Daytona is having to recover its international status after the latter says it all.

Well push privateer cars, or at least multiples available, another year most likely. Audi, Porsche and Lamborghini all have dibs on Multimatic chassis now, although Lamborghini has to wait a year for their toys.

Will the Lambo use the same engine as Porsche and Audi? Didn't see that in the article, but seems most likely.

I'm interested to see how different the bodywork will be between the 3 makes. If they all look different (and good) then I think the engine similarities can be overlooked...... by some of us.

Thats for sure a good looking car always overcomes many of the other flaws for me. Especially for prototypes. Hope these LMDH cars have a lot of wiggle room to customize the body style. The Corvette DP really set the standard there.

Key words those........

I honestly don't expect big changes about bodyworks, maybe something like lights design details or a different shape of nose... but actually I mean more some kind of vanity panel than a real aero part like the panel over the nose of acura dpi.
For sure the engine will be the same for the 3 cars, afterall looking back to about 20 years ago, bentley speed8 shared same engine of R8 (2003 bently had an enlarged version tho)

They were rumored to be using the engine that's already shared in the SUVs. But I'll put money down on the same engine across the line.

So it seems that aside from engines and bodywork, the Multimatic chassis will basically be a VAG proprietary chassis. Which IMO is sort of doing LMH on the cheap (not building the whole car from scratch). At least this means that if there's a LMP2 customer version it should be a lot better than the car Riley was involved with.

Why would they have the same as an SUV? Really quite strange if true, unless they know something we don't

Possibly for the same reason the engine in the Urus is the same unit in a number of VAG cars including:

Audi RS6, RS7, S8
Porsche Panamera,
Bentley Continental GT,

An engine used in an SUV can also be used in many other vehicle types with no issue if mapped properly.

Such a shame. Id have loved a Lambo V10 in a prototype. Still, hopefully it looks different at least. Variety is the spice of life and all that...

[S griffin]

Yeah I do miss that. Hopefully someone like Lambo will be back, but it’s not looking like happening soon sadly. But there’s still enough different chassis and manufacturers to keep the series healthy

[crmalcolm]

We're starting to get a lot of strong reports that Lamborghini are all but confirmed for an LMDh programme - or more accurately, they have a programme but just need a little bit of customer integration to complete the entry.

'RACER has learned the Italian supercar constructor will become IMSA’s sixth LMDh manufacturer after recently greenlighting a factory prototype program in the upcoming hybrid formula due to start in 2023. The Lamborghini Squadra Corse effort is primed to debut in 2024 and will have a heavy emphasis on customer integration.'

“We are not 100 percent over the line, I can confirm that, but if I was to say we’re 90 percent of the way there, that would be pretty accurate,” Lamborghini senior motorsport manager Chris Ward told RACER. “We’ve got a couple of I’s to dot and T’s to cross with a couple of the main providers.

“That’s what has separated us from a lot of the manufacturers; historically, we don’t go factory racing in the way that you might see Porsche or others go factory racing. To get us all the way there, it’s going to take a customer effort behind it.

“But we’re in a fortunate position as a manufacturer to have the relationships and individuals among our existing and growing portfolio that could help us achieve that. So those are the elements that we’ve got to really get over the line with to make sure that it’s 100 percent.”

[S griffin]

Actually thinking about I’m not surprised, this series could really help their brand. We’ll have to wait and see. Might have to wait till 2023, but that shouldn’t be a problem. Thanks for that, let’s listen out for further news. Great news for the series if true

2023 le mans will be epic!
toyota vs peugeot vs ferrari vs audi vs porsche vs cadillac vs (hopefully) bmw

[J Jay]

Something tells me this would have been announced right after Le Mans, if not for a certain Ferrari...

Really pleased in particular to see WEC confirmed, and for AXR to be involved.

[joeb]

Makes me wonder if they had already come up with this render months ago, or if they were "inspired" by the Peugeot?

[broadrun96]

As said over on the other thread, it feels like they were ready but wanted their own spotlight. And what Cadillac wants to put in the back of the car, ECR has been let go as supplier and they didn't announce what they'll use. Odds on it being turbo'd and related, at least in marketing terms, to a street product?

[seanyb505]

Am I dumb or aren't lmdh to be based on p2 chassis? Me thinks that whole no wing is not going to make it to the Cadillac dallara. If anything I'm expecting a facelifted current caddy. With maybe a blackwing tie in? But I think that ship may have sailed by the time a motorsport program could fully leverage that engine.

I have been questioning this the whole time. We (fans) don't know what the next set of P2 regs are, but somehow Porsche will be testing their car this winter that is based on said P2 car? Perhaps it is easy enough for the 4 chassis suppliers to learn some basic info from the ACO and then just make the tubs to the correct dimensions. I don't know if the LMdH are supposed to run the P2 spec suspensions and electronics, or if that is free for the manufacturers to decide.

But it appears what we wont see is something like the current Acura, where they take an Oreca and just throw an additional piece of carbon fiber on the front. Sounds like the manufacturers will have to come up with all of the bodywork for their designs.

I'm starting to fear that 2023 LMDh tubs and 2024 LMP2 tubs are actually 2017 LMP2 tubs with a fresh homologation sticker.

I'm yet to see anything from a reliable source, let alone official, to confirm this. If you have links please share.

it's impossible because lmdh will have same size of LMH, so a different wheelbase requires a different tub. As consequence lmp2 tubs will be different.
For the rest, there is google.
Some time ago max angelelli now working for dallara told in an interview that new lmp2 tubs will be really different from the actual ones and everything will be made starting from zero.
Of course none else has the same know how of oreca, maybe only multimatic is the one that gets closer, so I think that also for lmp2 next gen oreca will have the upper hand and most share of business.

[broadrun96]

They have not yet spec'd the P2 chassis on which the LMDh will be built. It appears they are building the LMDh chassis and then removing what is needed, likely less power and some suspension "downgrade" (for lack of a better term).

That said, chances of no rear wing seem low but everyone who thinks that render is anywhere near the final product raise their hand, I have a great deal on a bridge for you

[canaglia]

next gen lmp2 will be designed in 4:1 like LMH, according to this manufacturers should have more freedom but considering lmp2 are made to be sold to private teams I think next-gen lmp2 will be as less complex as possible aero/chassis wise.
It's up to lmdh manufacturers to change and update the package starting from the lmp2 chassis, but I don't think we will see radical designs from the basic package... to make it simple, a peugeot-like car it's extremely unlikely for a lmdh.
Anyway considering porsche and audi started working with multimatic since early 2020 and according to some rumors WV bought exclusives rights for that chassis, I think porsche/audi multimatic lmdh could be a more "customized" car than bmw and cadillac which it seems are still on early development stage.
