Le Mans Hypercars, unlike Formula 1, have very open regulations regarding the engines. If it runs on gas, and has four strokes - yeah, you can run it! This leads to wildly different strategies within the world of endurance racing: small engines, large engines, turbo engines, naturally aspirated engines, V6 engines, V8 engines (you can even run rotary!), hybrid or not, the world of endurance racing has it all. It's fascinating to see manufacturers choose different strategies when it comes to powertrain, including the behemoth, 8800 RPM naturally aspirated 5.5L V8 engine used in the Cadillac V-LMDh.
Endurance racing, however, is fairly complicated. This video won't get into the differences between IMSA & WEC, LMDh vs LMH, or the other dozen acronyms used in this fairly complicated motorsport. The powertrains are awesome, the racing is awesome, but the series could use a little help in terms of educational content surrounding the rules, team approaches, and various strategies. All of that said, I had an incredible experience attending the centenary of the 24 Hours of Le Mans! 100 years as of 2023! Enjoy the video and learn all about the powertrain strategies in this sport.

[@ReXzz]

"Actually"😂

[@EngineeringExplained]

*Worth noting!* This video is specific to the 24 Hours of Le Mans race (and more specifically, Cadillac's LMDh build), and doesn't dive into the differences between LMDh & LMH, WEC & IMSA, and the differences between the cars used in each (for example, LMH cars can have 200kW of electric power). As an introductory video on the subject, I didn't want to constantly have to clarify between different acronyms. Something I think Formula 1 does really well are their educational pieces surrounding technical aspects of the sport - would be great to see the same out of WEC/IMSA!

[@sidewalkere]

It's specific to the LMDh tech regs, in fact. LMH run at the 24 Hours of Le Mans (one won it, even). So you can't really say that at Le Mans they are limited to 30kW electric, because they really aren't. LMDh specifically are. ;) Might seem nit-picky, and I get your point of the confusing acronyms, but that shouldn't stand in the way of facts. ;) P.S.: another nit-pick, if you put the electric motor on the front axle, then you definitely have more than 30kW, since only LMH can do it. :)

[@DuvJones]

@@sidewalkere I was about to pick that nit myself, because LMDh's *HAVE* to be hybrid. They get no choice in the matter, but the flip-side of that is that for LMDh's that isn't their part.... Cadillac, Porsche, BMW & Acura (*cough*Honda*cough*, in IMSA-only at the moment) (as of next year to be joined by Alpine's A424Beta) do not supply the electric motor and battery themselves, that comes from a set of suppliers that adhere to the same spec for each. The result is that costs are controlled, for the most part. This is both for WEC and IMSA. Ferrari, Toyota, Peugeot, Glickenhaus, and Vanwall don't have this limitation being LMH's, with Ferrari, Peugeot & Toyota being the hybrids in that category. In fact I highly suspect that the reason to you are seeing Ferrari in WEC (and therefore taking LeMans) has alot to do with the F1 cost cap and their rather heated displeasure at it. Ferrari loved to toss money that that division of the company, it part of the reason that it was founded. So when FIA said "None of that, here is a cost cap", Ferrari quickly spun up a LMH project and did what they wanted with the money. I am not sure if that was the direct response but the result speaks for themselves. Then there is Peugeot's ground effect car, with wild aero and no rear wing....... Yeah, LMH's can take some liberties. Also, I am not so sure that the rotary in an option for the powertrain, last that I heard on that is that it was banned outright after the 787B legendary run.... but that was for the Group C rules and the times.... they have changed, I am not so sure that the ban still applies.

[@racingmaniacgt1]

I think its arguable with rotary being 4 stroke, which I think the rule specified as 4 stroke.... Also in LMH the Hybrid activation speed is part of the BoP, Ferrari/Toyota was actually at 190kph. And Peugeot at 150kph. Its dependent on tire size choice and other consideration....

[@DuvJones]

@@racingmaniacgt1 As I said, I am not sure if the rotary ban still applies but at the moment... No manufacturer seems to wants to dare it. We will have to see what other LMH's/LMDh's come out (their is going to be another by the end of this season, and more next year) but I suspect that very few want to touch the rotary if only because reliability is a huge concern. Fair enough with the LMH's but the fact remains that cost is no objective barrier to them, if their are other rules that tame performance... cool. Been liking the racing so far.

[@Wafflefrieslmdh]

We would love a video on that anyhow!

[@ReXzz]

Correction: Hybrid activation threshold for AWD cars is NOT 120 km/h as claimed in the video. It depends on tire width and it's 190 km/h for both Toyota & Ferrari and it's 150 km/h for Peugeot!

[@falinestixiaolong9691]

It is also active at very low speed, notably in the pitlane.

[@fsendventd]

@@ReXzz I thought none of the cars were allowed to use any hybrid power until higher speeds except in the pits, so that way they were all combustion only at lower speeds to equalize it.

[@shiftfocus1]

I’ve been a huge LeMans fan since that year Audi had the brilliant idea to make the entire rear section of the car a replaceable element, cutting a gearbox change from most of an hour to 5 minutes. ACO changed the rules after that but it still gave an example of both the level of innovation possible, and the fact that the engineers and mechanics remain an active part of the team until 4:00 on Sunday. This year did not disappoint. After 23-1/2 hours, the two leading cars were still on the same lap. And hearts stopped when the leading Ferrari had trouble restarting after their last fuel stop. It’s simply brilliant.

[@bolerkai]

Since there is so much equalization, seems Cadilac is going for the "keep it simple and make it to the end of the race" strategy. BTW great video had no idea there were so many detailed rules and regulations.

@@shiftfocus1 The rule of endurance racing, LeMans especially because.... LeMan's isn't a full year race track. You can only prepare for it so much for it and you only get five days total for the track (for 2 Practice & Qualifying sessions [the last Qualifying session dubbed Hyperpole] and the race itself) after that? Part that is used for the Mulsanne straight... that is a public highway. The chicanes on it? Roundabouts. You only get one real shot to have an impact on it. Lose and that is it.

None of the chicanes on track are public roads, and technically Mulsanne and Arnage entry are now full race track. The only track corner fully part of the roadway is Indianapolis.

So happy you share some light onto the WEC. I get that from an engineering perspective it may not seem as interesting, but despite mandated downforce and drag figures the manufacturers came up with some interesting aero details to gain hidden advantages.

Very nice video! One more thing to note regarding the BoP in my opinion is that is also helps to motivate manufacturers to invest in their brands' motorsport sections. If no BoP would be present, I think way less teams would even start to challenge the Toyota's recent rule over the endurance racing. By having some security in the fact that the rules will help you balance out the head start other team might already have, I think the beancounters are then more willing to allow their brand to take part in the sport.

I think the engineering to come out of endurance racing is way better than what comes from F1. Endurance cars are built to not just run high power, but to keep doing it for an extended period of time. That type of engineering has more real world applications than an engine that only produces power for a couple of hours a day.

[@chubs2312]

Yep. Precisely. F1 race distance in the entire calendar is about the same as what the hypercars cover at Le Mans. F1 teams go through several components across the year while you want to not have to replace anything during an endurance race. I think endurance racing is mental overall.

[@ebonfortress]

It’s mostly electronics now. All the mechanical stuff is way too expensive to be used in road cars. And sometimes road cars are more advanced than race cars eg with active suspension banned

[@sweetcheels]

I mean sure but any engine that revs at 13-15K revs per min is bound to unravel themselves. Especially when you throw forced induction at it and design it to rev high and rev fast.

[@ebonfortress]

@@sweetcheels reliability is one thing but a racing engine will be rather uncomfortable to drive on the street. And as long as racing and daily driving engines have different goals it won’t be that easy to use whatever racing tech on the road.

Restrictions lead to really interesting changes for engines. A great example is the new gt3 mustang being 5.4 L . It has a 94mm bore and 97mm stroke. Typically you'd see an over square design like you do on the base 5.0 (93x92.7) but rules limit intake size so the torque for rpm tradoff is worth it.

WEC rules say that the engine shall not make more than 670hp. However, the thing about normal engines, when they say they have 670hp, it has a MAXIMUM of 670hp at a specific rpm, and most of the time it doesn't. so it makes sense to make an engine that has more than the 670hp, and then restrict it thru mapping to increase the rev range that max power is developed. And of course, the other way is to fill in the power difference with the electric motors.

Would like to see greater novelty in car construction. Here is one race series we came up with: 1) each grid (the set of cars that show up for the race) is ranked higher (ie. closer to pole position for the race start) for grid positions as the size of their engine shrinks. So a 2-cylinder engine has a qualifying advantage to a 4- or 6-cylinder engine 2) absolutely no limits to the engine construction. 2-stroke, or 4-stroke, or diesel, or rotary, or some novel design - only requirement is the engine must run on no greater than 93 octane pump gas (mixed with 2-stroke oil for a 2-stroke motor) or pump-grade diesel. Limit of 1 liter max. 3) each car is ranked higher up the grid as the team budgets shrink. So a team that spends $100k is ranked higher on the grid than a team that spends $500k 4) absolute limit of $1 million for the team budget 5) there must be 5 cameras on each car: cockpit, front-facing, rear-facing, and one facing outward from each side So the race will consist of 1- or 2-cylinder engines, and really cheap cars. This will get rid of the 'throw money at the problem' people who basically ruined F1. It will shift emphasis back to HUMAN CLEVERNESS in engineering. F1 and Indy car had much more freedom for car design in the past (remember the turbine cars from Lotus and Granetelli at the Indy 500?) Colin Chapman's ground effects and so many other design novelties would never be allowed - all designs are set and heavily influenced by Mercedes, et al. *_FORMULA ONE has become as exciting as WATCHING A GUY PLAY MINIATURE GOLF FOR 2 HOURS_* They forgot that racing is a SPECTATOR sport. NOVELTY is why people will pay for tickets. Not sameness. SAMENESS lacks the appeal of novelty. You want to see some real racing? Watch the Isle of Man TT.

I wish F1 would bring back the 1989 engine regulations. Back then you could do whatever engine layout you wanted up to 12 cylinders, and a maximum displacement of 3.5 liters. It would be interesting to see what the engine manufacturers would make to compete.

[@Velocitist]

Exactly, depending on the design decisions that the engine manufacturers make. To keep and even playing field I think they should change how they regulate powertrain design, N/A or forced induction. Boost pressure and rev limit should be inversely proportional to the engine size, but for naturally aspirated engines, they would be instead, just regulating specific things such port volume and flow, rev limit and restrictor size. Wasn’t there at one point in F1 history, where V12s, V10s, and V8s shared the same grid? I think what they should do, instead is that, make the electrical components specific to the hybrid system, such as the electric motors, batteries, inverters, and ECU standard equipment supplied by the FIA, but let the manufactures play with engine configurations. Imagine if Ferrari brought back their V12 that can rev to the moon? Isn’t Porsche and Audi coming back? We know Porsche can do really good powertrains, their 919 has a turbocharged V4 engine hooked up to the hybrid system. Imagine if they brought that kind of technology into F1, what if Renault Alpine looked into their past to prepare for the future? Look at the stuff they did for Group B and Group S, imagine, four-cylinder engines came back to F1. Isn’t and American team join too? A 2026 V8 F1 car? That sounds like something that would crash the Internet the moment someone steps on its throttle

[@kidpagronprimsank05]

Problem is that, eventually, everyone will go to the one that turns out to be most effective design (in 3.5l, it either V10 or V8). That's why in F1 (and WRC) mandate single engine type

[@2rude307]

I've just watched a video from Toyota about hybrid systems. They have these things called MG1 and MG2. I hope you explain them in the future. Thanks!

[@The-fs5wn]

LMP1 and LMP2 are my favorites. With the right modifications they can be as fast or faster than modern F1 cars, since the only real engine regs were that you needed a 1.9 liter turbo V6 and had to use race gas (4 liter V8 for LMP2). The exhaust recovery systems and MGU were much more powerful, they had AWD, and there was more room on the body to put dive planes for ground effect downforce (though there were limits on how much ground effect you could make). Porsche broke the Nurburgring lap record by modifying a 919 LMP1 car, a record previously held by a modern F1 car, with just a 10 percent increase in downforce.

So. As always a great explanation. However I must say that the cosworth DFV, many Indy, and of course 24h of Le Mans engines had a flat plane V8 layout. Vibrations aren't an issue in that terms in an Endurance race. But, anyway, that Cadillac powerplant sounds insane

[@HB-C_U_L8R]

One edit you should make is that the boost numbers are set by the BOP from IMSA/FIA/ACO, usually a week or more before the race. Something interesting is that the 5.5L V8 DPI Cadillacs in IMSA were the most fuel efficient cars in the category even though they were racing against a Nissan 3.8L TT V6, an Acura 3.5L TT V6, and a Mazda 2.0L TT I4. Another interesting thing is that GM invested a lot of money making their pushrod V8's breath more easily in the 1990's (at one point the LS V8 was the most efficiently breathing engine on Earth). They did this for several reasons: 1) it was cheaper to do this than develop a new engine family from scratch 2) to improve fuel economy and reduce emissions 3) a pushrod engine is more compact than overhead cam design (the last generation of Chevy Impala had an option for a FWD longitudinally mounted LS V8, and also google LS swapped Volkswagen from some crazy stuff).

I'd prefer fewer rules... Great video!

[@watchnocatch171]

The biggest problem I have wit BOP is that there is the chance that you simply have to be lucky to have the best package without actually having the best package because the officials messed up the BOP. For example this year a Ferrari won the N24H the first time. The 296GT3 is a new car so officials have little data for it and when I watched the race I immidiately saw how fast the car was compared to the others on the long straight. They were pretty much given the victory on the silver plate. It's simply not fair. And at Le Mans Toyota, although I'm no Toyota fan got hit by BOP before the weekend more than any other car.

[@jongoode3296]

That's a reasonable concern. The only scientific solution is to have two races, one with BOP and the other without.

[@favianmadrid6345]

@@jongoode3296sounds like crying to me lmaooo

[@DuvJones]

Actually... the race winner at LeMans got hit with the second biggest penalty with the BoP adjustment. Yeah, Toyota got nailed, that is what happens when you are 1-2 a lot (and it happened twice in WEC this year so far, Sebring and Spa) but so did Ferrari and I will have to remind you that Car 51 won... They were not pleased with it at the time. Today? Do you think that they care? As for the N24H... I can see the problem with that because the only racing data on the 296GT3 was at IMSA. They are not connected with the endurance or GT circuits and a new car harms that since it's just out of the blue for all purposes. Next year is going to be a handful.

[@LG-ct8tw]

They actually got the perfomance very, very close. Until Hirakawa sent the Toyota off the black stuff they had a very good chance. The Ferrari wasn't cruising then.

[@tristanhipps604]

I love endurance racing the BOP has been a real drag especially when there is a clear sweat heart like when ford brought back the GT…. They sand bagged and had a more then friendly BOP just so the fair tail ending would happen like wrestling match

F1 rules : get whatever output you want from your engine as long as they are all the same Hypercars rules : do whatever you want with your engine as long as they all have the same output

[@LG-ct8tw]

The problem with F1 is engines are frozen you cannot change anything except for reliability reasons so you cannot catch up with a more powerful or more efficient engine.

[@simonrano8072]

@@LG-ct8tw Thanks to Karen Horner secretly preparing a engine boost juste before the freeze and work around the aero engineering advantage they have. With hypercar you can change what you want but your output is regulated by mandatory curves and values. And if your car happen to be too fast you have to sand bag by regulation. It is like "come and show off your techs and designs, the regulation will ensure that lap time is close"

In person F1 is very impressive I find it pretty boring watching on screen but gt and le mans series cars are far more interesting rules wise and to watch and even the type of race events on the calendar are just better 👌

[@Alan-ww8vi]

No joke, I went to a F1 race in person many years ago and almost feel asleep half way through.

[@OboeCanAm]

Are Hypercar engines cooler than F1? After LeMans, I think Ferrari would say "SÌ".

[@DuvJones]

Actually, even before that.... Enzo LOVED endurance racing. His company, Ferrari was founded on that passion. Last time Ferrari was at LeMans was when he was alive and they had a reputation. This year, Ferrari is honestly questioning why it took them 50 years to come back if it was this "easy".

[@falinestixiaolong9691]

@@DuvJones It was not that easy. Prototype racing is expensive, and they have also been racing in F1 for as long as it existed. For the most part of those 50 years, they just couldn't afford it, and today they are still the only manufacturer to compete in both F1 and Hypercar (until Alpine next year, the A480 wasn't their design), and it took the disappearance of the prohibitely expensive LMP1 program for them to return. And they also just built the car, it is operated by AF Corse. Money is the game, and the Hypercar program really changed the game. I don't think it could have happened before.

[@ral0958]

3:28 is a rotary a 4stroke engine? Great video, I love lemans!!!!!!

[@vvevvevvvv]

It is

[@corneliusmcmuffin3256]

Honestly F1 was cool as a kid, but nowadays I feel like it was only interesting up until the 70s, possibly 80s. The most enjoyable part of racing is teams constantly bending the rules and pushing boundaries to make the best vehicle possible, and it becomes much less interesting when too many restrictions are placed. Le Mans gets around this by running multiple different classes in the same race, which makes things a lot more entertaining to watch.

[@bluerider0988]

While I agree that F1 is a engineering competition, it's not just the car. If that was the case then Red Bull should be finishing 1-2 every race, however Max wins and often Perez is way behind. This means that there is the element of the driver as well. Great videos. Keep them coming.

I still miss Porsche 919 with its V4 (!) engine. A very rare engine configuration for a racing car.

2:40 :( RIP the legendary rotary 787B

[@DapperHesher]

R26B, 787 was the car. The motor itself wasn't very good. Absolute boat anchor compared to modern piston engines and required subframing as you can stress-member a Wankel.

[@MultiMinors]

@@DapperHesher 787b was the car, 787 was earlier model. Motor proved itself to last the whole race and was in excelent condition afterwards, to the point that the engine could go for another round while the chassis was almost ripped apart. True example of what a rotary is capable of in racing applications

[@DapperHesher]

@@MultiMinors You're talking about one race with a lot of weather and random attrition. Overall, the Wankel-powered 757, 767/767B, 787/787B, and RX-792P cars were all largely uncompetitive race cars over the course of their respective full race series'. The 787B as a great race car is a myth.

[@visualizecreate2530]

I “love” this guy!!

[@DefinitelyNotEmma]

Think balance of performance is very much counter productive to the LMH class. Motorsport is just as much about the engineering as it is about the driving. Artificially decreasing performance is not in the spirit of the sport. That's also why I don't mind F1s periods of dominance. It's the task of the other teams to catch up, not the the FIA to step in. If people would be really interested in that, then spec series with the same vehicles across the whole field would be more popular. For example LMP2 consists solely of the Orecas nowadays. But that isn't the case. People want to see different cars from different teams competing. That's why Rally, GT racing, F1 and LMP1/LMH are generally the most popular motorsports categories. Edit: It also makes the engine variety much less important and exciting, considering they all are limited to the same power output. The less restrictions are within motorsport, the more exciting it gets, that's why Group B is generally considered the golden age of the rally sport.

[@J-Eagan]

Yeah, I agree it’s better when there’s more variety between competitors.

[@enemyspotted2467]

While I disagree with the spirit of BoP, I do believe it is necessary to keep the sport alive. Without it, you get the formula one problem of whoever spends the most wins the most and teams start dropping out. For years, the WEC had maybe 5-6 cars running the the top class, and now there’s 16! You cannot argue that it hasn’t been good for the sport. While it can be exciting (for the first few races) seeing a team build a monster of car, we nearly lost LMP1 because no one else could afford, or didn’t have any interest in a financial pissing contest with toyota. Quite simply, LMH/DH wouldn’t exist without BoP Also, the intended function if BoP is not to make the cars 100% equal, but the reign the cars more closely together. If all goes according to plan, better engineered cars will still perform, and the lesser cars will not do well. We saw this in Le Mans this year, Ferrari and Toyota still came out on top while the lesser cars did not. BoP is an adaptive system that changes race to race. When implemented correctly, it will make the sport more appealing for new teams while still rewarding clever engineering. The FIA is trying to achieve the same thing in f1 with cost caps, but it clearly isn’t working (not yet anyway, we’ll see). If you want to sit there and watch the big spender dominate race after race, be my guest. I took a hiatus from f1 when mercedes won 7 championships in a row, and I believe the majority of fans share the same sentiment. Personally, I’ve started to prefer IndyCar to f1 because it is a spec series and the racing is pure. We’ve had 5 different winners across 9 races so far this season, it’s become an absolute treat to watch!

Thank you for this. It has re-ignited my interest in endurance racing. I've always wanted F1 to work with these principals. Any kind of engine, just limit the power. All manufacturers running the same engine configuration, all sounding the same is extremely boring to me. I used to love when F1 had all kinds of different engine configurations. Great video!
