The difference is that the LMH/LMDH are much slower than Group C cars because of the speed record. Since 1990 till today, FIA placed 2 chicanes in Mulsanne straight that prevented speed record and banned rotary engines because it was too noisy which was a shame and it made the endurance series switched from Group C to GT1 cars in 1995 till 2000.
A pretty critical detail about the all wheel drive lmh cars, the awd only engages at a certain speed so it doesn’t give them any acceleration advantage
only correction to make is that the LMDh are not based on next gen LMP2 Chassis. They were originally going to be based on next gen LMP2 Chassis, but recently the ACO completely rewrote the next gen LMP2 Regs so that is no longer the case.
For the first time in years sports cars look like they are back on top where they belong. Sports car racing is older than Grand Prix (F1). Beyond the prototype class they look like real cars that are on the street. Love it. Thanks 🎸🔪
I also wish the 2 chicanes in Mulsanne straight should be removed and for hybrid cars, they should be around between 1000-1100bhp in order to have masive speed record as Group C cars.
Fantastic video and was exactly what I was looking for. Subscribed. If you are looking for a future subject to cover, I would love to know more about the likes of Porsche and BMW participating in LMDh, which is more restrictive, instead of LMH, which would give them more opportunities for advanced development.

Thank you, I am really happy to hear that you have subscribed! I have a video here which may help which explains all the details of each Hypercar for 2025. ruclips.net/video/h3cpxS7l6Bk/видео.htmlsi=EM05JrJttRB0LyER
Great classes, so many options like in Group C in the past. I love it. My personal favorite will be the Aston with its V12 engine. I hope Mercedes, Audi, Mclaren and Chevrolet will join some day
The problem nowadays is that with all these letters are quite complicated for new fan. Basically, let's start with the fact that are 2 distinct things in racing outside of F1: Car regulations and championship classes. That said, LMH and lmdh are car regulations. Now the complicated part. In IMSA (the north american endurance series) and in WEC you have respectively GTP and Hypercar. GTP and Hypercar are the championship classes in which you find the car that follows the LMH and LMDh regulations. Technically you could build an LMH car and this car would never compete in the Hypercar class of the WEC. I hope I make it more clear for the new comers. Don't hesitate if you have any questions
If all 14 manufacturer race in the top class at WEC we won't probably see the lmp2 because of the 2 cars per manufacturer rule so 14 x 2 = 28 plus those privateer teams like proton and af course so it will be 30 then those large numbers of lmgt3 then lmp2 will be erase in the WEC
I wish FIA/ACO to get rid of the 2 chicanes in Mulsanne stright, abolish BOP & 2500 cars per year and bring back the regulations by making LMH/LMDH/LMP1 to have high speed as Group C cars like between 400 & 420kph(248-261mph) & cornering speed like Super Formula & motorcycles & allow various tires like Super GT for factory & customer teams.
That 2500 car requirement is a IMSA rule & no BOP = no mfg's AKA LMP1 from 2018 till its demise when Toyota was the only mfg in lmp1H due its rising costs
They need more power. Most of them are already as light as they can get but the hybrid powertrains bump them up by around 200-250lbs compared to the heaviest LMP1's. If they get them up to about 750hp then they can get closer to LMP1 speeds/laptimes
The old LMP1's were rocket ships - which was nice, but I think the ACO and IMSA have got Hypercar just about right. Most of the performance difference is due to the extra weight and lower downforce of the Hypercars - and as a result they move around alot. Most importantly - they still *look* fast and they race really well. Who really cares about the lap time if the cars are a joy to watch?
@mattwhorlow9900 can't disagree. The racing has been mad good especially this past season. And with more manufacturers on the way it will be even better
love it and i hope for 2030 they blend the lmh and lmdh into one rule set with a bit more power or less drag for better top speeds. I wish the lemans laptimes to fall under the 3 mins
Yeah a completely blended ruleset would be great. My hope is that you get a GT1 style class where the tintop has to be based on a hypercar that is actually sold. BOP should make a class like that viable
For the Valkyrie LMH which is a non-hybrid hypercar, the starting motor and KERS actually use as a catapult and backup generator is the reason why it started from EV mode and then switched to gas mode. Both KERS & starting motor can prevent non-hybrid hypercars from ending up like Glickenhaus and Vanwall.
I’m surprised some teams went down the LMH route. LMH are so much more expensive, bespoke and more advanced than the spec restrictive LMDh cars, yet BoP and the regs means their performance is on a par with the LMDh cars. And that’s probably because the DPi cars which LMDh replaced were essentially LMP2 style cars, so costs and performance needed to be kept similar.
The LMH route allows the manufacturer to explore and implement their own drive train systems. Especially with the hybrid as its of their own design and choosing. The lmdh is basically a spec class of sorts; their only free choice is the engine and styling aspect everything is a controlled part
The cars can have pretty big differences even with BoP. Before the Hybrids, the Acura DPi was incredible on bumpy street circuits with it's much better damping, the Cadillac was great anywhere that needed it's torque, the Mazdas were good at tracks where torque didn't matter as much and the Nissans were amazing at night running as their engines seemed to love it.
They sell around 6,400 per year, so they are well over the minimum for IMSA. I rarely see a newer A.M. on the road, so I am very surprised by the number too!
I hope Ford commits this time. If they do and debut in 2026, they will have 4 years of racing the car instead of 3 years if they debut in 2027. Does it make sense to debut in 2027?
They won't make it for 2026 if they haven't started development on the car. Also it isn't unlikely that with so much manufacturer support that the LMDh and LMH regulations get extended again past 2029 with probably the only change is some tweeking with the regs to allow hydrogen powered cars to compete and make them competitive
Now the reg's are extended to 29, about time both Jaguar and Audi brought themselves back into the top flight. Let's not forget that Audi had a project ready to go and then at the last second canned it to go to F1. It's still a possibility in my opinion. JUST IMAGINE!!!
I don’t have hopes for Audi returning to prototype racing as they’re already struggling with their F1 team.. and as for jaguar I mean look at mess that is Their current brand image I don’t think they’ll return to ICE cars or racing as such.
I wish Jaguar should return to endurance series but it got completely destroyed by wokeness and their current brand image.🤦♂️ For Audi, they struggle with F1 entry but both Lamborghini and Porsche are always race in every motorsport series despite they're both VW. Lambo just stayed away from WEC for only this year but it'll return with the Temerario.🤷♂️
For customer teams, of course they're allowed to run with a single car but for the factory teams, they're required to have 2 cars because of the 2 car mandate policy.
if the lmdh can't be derived from road cars how did the AMR Valkyrie get into the class? because this isn't a hybrid system, and doesn't follow a lot of the rules that you mentioned for LMDH
I don’t quite understand. If you say the regs are quite different, how’re some manufacturers like Porsche, Cadillac and BMW compete in both series? Does that mean that the LMH BMW is different to the LMDh BMW? Sorry that I’m being quite slow
After some googling, both rulesets have similar performance windows. Min weight, max power, and downforce and drag figures are the same in both regulations. The only difference ends up being that LMH cars can be 4wheel drive. They basically wrote the rulesets with compatibility in mind, and there's always BoP to nerf the overperforming regulation.
Each manufacturer commits to one regulation, so in the case of Porsche, Cadillac, and BMW they all pick LMDh and run an LMDh car in the WEC and IMSA. Hope this helps!
The only pissy thing the fia/aco did is made the rule that teams have to run at least 2 cars which is why IF had to pull out and vanwall despite the behind the scenes nonsense cant run anymore The fia as per always meddle with things so the big OEMs have the say in how things operate
I'm not sure if Vanwall of IF would have raced even if it was only one car. IF tried last year and couldn't complete the season, Vanwall was in P nowhere all year. The two car rule is somewhat necessary, if a manufacturer doesn't have two cars they wouldn't be competitive anyway and would have no chance in the manufacturer standings.
Costs and manufacturer desire. Lmh is more expensive but grants more manufacturing freedom, vice Versa for lmdh. Also worth noting that lmdh was also designed to be aligned with the new LMP2 regs that were being introduced before they were discarded as well.
It seems that the BoP in both series seems to lead to or favor the outcomes of races.I don`t think that is fair to the drivers or the manufacturers. Just my take. I think weight and max HP on the dyno should be the only balance, maybe limiting drive configuration to rear wheel drive or all 4 wheel drive.
That wouldn't work to well either as every car has different cateristics for eg at lemans the ferrari's & lil less prominently the Toyota's were the fastest cars down the mullsane despite being the heaviest & having the lower power & the porsche's & cadi's were the quickest on average through the medium to high speed porsche curves where it's practically impossible to pass
@@Maenfyprecisely this. BOP ensuring good racing is a side effect, its main purpose is to prevent manufacturers from spending millions to enhance performance.
The problem is the BOP & 2 chicanes that actually prevented them achieve massive speed record like Group C cars do. It's better that the 2 chicanes should be removed, abolishing BOP and the regulations should be around between 1000-1100bhp(including hybrid systems on LMDH/LMH) in order to make them to reach the same speed as the Peugeot W88, Porsche 962C, Jaguar XJR-9 & Mercedes C11.
