""Porsche and Cadillac are so far the only confirmed LMDh entrants that are set to compete in the WEC full-time in 2023. Acura and BMW are due to focus on IMSA.""

No disrespect to the privateers but after the last few years of Toyota steam rollering everyone, the idea of 'only' Toyota, Glickenhaus, Peugeot, Ferrari, Cadillac and Porsche in Hypercar is pretty sweet. Can't wait.

Good point! Also made me think, has anyone but Porsche in LMDh specifically stated a customer intention? this could be in IMSA or wec, but I can't recall others. I know Glick will sell you a car if interested, but has Toyota, Peugeot, or Ferrari stated a similar intent?

From what it is written in this article (written in feb. 2022), the Ferrari LMH should hit the track in May or in June.

Hopefully this works as intended and we aren't muttering about BoP changes everywhere.

"“We found that by doing simulation from track to track, there are some speeds where it all matches on all the tracks, and the effect of four-wheel-drive and two-wheel-drive will be identical,” he explained.

“We would like to go to that solution. Otherwise it would make a complication on the BoP [to do track by track BoP].

“If the BoP is changing track by track, you look at the BoP and say, ‘what’s going on?’ Nobody would understand. It would be pointless.”"

What happened to the GTP naming that was to replace LMDh?

Part 1.2 and 1.3 regarding manufacture and automotive is quite restrictive.
2500 units a year, where only cars with drive on the rear wheels will be counted towards that number.
This would mean that a manufacture like Peugeot would not be able to compete in LMDh, as their cars are all front wheel drive. (Unless four wheel drive is accepted)

Part 3.4.1 effectively bans the Nismo GTR and Audi R15 principles of air flow through the car.

That will be the class name in the IMSA, not in the FIA WEC.

GTP is expected be the equivalent of "Hypercar" name in WEC. So just a class name, still two actual technical rulesets.

Didn't want to put this in the positivity thread because of the response it may generate, but Aston has been giving rides in their hypercar that is "faster than lmp1" to journalists

https://www.roadandtrack.com/reviews...0Non%20Openers

That car still looks amazing, and probably sounds the part too!

This is probably the best place for this. After all - LMP2 are still prototypes.

From Phil Hanson (United Autosports) on MWM talking about the pit crew duties. Given the reduced tank size, and therefore stint length, the pit crew will be in service every 30 minutes* for the duration of the race, with an estimated 40-45 pit stops.

That leaves precious little time to even sit down, never mind get anything resembling a rest. The regs may have reached the point where personnel safety becomes a concern.

*The stint length for LMP2 is longer, but when you factor in preparation and clearing up time, this is what Hanson said UA's pit crew will be working to.

That is an intense schedule. At least they don't change tyres every time. Pit crews will be happy to see some safety cars.

I have never really understood the point of mandating so short stints via fuel tank sizes to begin with. This trend goes back a long time, at least a decade and including both P1/P2. Are pitstops supposed to be so exciting that it is better to have more of them.

Also there's a bit of irony in having historically the most efficient engines yet the shortest stint lengths.

Only thought would be with the reduced power and slowing of P2s already, how much slower would a say 25% bigger tank make them and how much harder on the new Goodyear tires?

Not at all arguing for more stops, less is better and not suggesting they actually thought of weight at all there but....?

There are no technical reasons to decrease fuel tank size to let lmp2 having shorter stint, WEC lmp2 got shorter stints because, despite extra weight, power cut and mandatory LM bodywork, performance wise they are very close to LMH, so forcing them to refuel more frequently is a cheap and artificial expedient to cut them off from leading LMH after 30 minutes. IMSA lmp2 can't keep up dpi pace, so IMSA didn't need to kill their power output and stint length.
Anyway when they were at 600hp full power, lmp2 could run about 40-42 minutes with 75L, rebellion and BR1 had similiar stint length with their 75/70L fuel tanks but were in the order of >700hp.
Gibson lmp2 engine has never been very efficient in general.

Pretty much all of that, with a tangent about the Gibson engine; it's its reliability and price that keep it around, its in/efficiency is essentially a moot point.

Stint length has been used as a form of balancing for a while; in the LMP1 heydays there were more than a few arguments about EoT and how it impacted the [diesel] Audis. A certain few posters would spend hours here debating the K-factor (used to equalise calorific fuel values) and tank sizes of the prototypes.

As long as the ACO are wedded to a 3:30 lap time, LMP2 in its current form requires significant pace reduction to keep them separate from LMH across a race distance. From teams and drivers' feedback, we're reaching the limit of what can be done in terms of pure pace (power, weight, aero, tyres) before it drastically alters the way the cars run. Mandating a maximum stint length via fuel tank size is just another tool in the arsenal, albeit it may have unintended consequences for the pit crews.

well about audi, that was different because eot tried to balance a technology (turbodiesel engine) that wasn't going to be as efficient as turbo petrol engines of toyota and porsche anyhow, but reducing fuel tank of lmp2 simply means: sorry guys we don't want you too close to big dudes... it's basically an unbalance of performances. Anyway, if ACO will keep on using bop test also for 24H race, we should expect slower laptimes since alpine now is only 560hp and toyota lost some power as well compared to last year (is also slightly heavier and lost the AWD advantage).

The ACO still aims 3'30'' per lap, so the BoP is fixed with decreasing values.

But it really makes no sense for Alpine to be at 560 hp only. I hope they will get some extra power. Are the BOP tables for Le Mans available already?

3'30'' was always about race pace... even underpowered lmp2 run faster than 3.30. Last year toyota pole was in 3.23.9, maybe this year pole will be in 3.25 range

On Test Day times, the Alpine is about 2.3 seconds down on last year's Test Day. However no-one with any sense who is hoping for any kind of break from the AO will show their hand fully on a Test Day...

I think I heard on the coverage that the hypercars all found about 5 seconds between the test and qualifying last year. I expect about the same if the conditions cooperate.
