*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!

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. :)

@@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.

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.

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.

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.

That type of engineering has more real world applications than an engine that only produces power for a couple of hours a day.

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.

Haha fair - I was referring to the engine design!

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.

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.

That was cool, thanks! So, Cadillac is in endurance racing (just) for the entertainment value it provides? It would be interesting to hear Barra give her thoughts on GM's racing viz a viz where GM sees the transportation market and how GM approaches racing.

Another excellent video. I learned so much. Would be interesting to find out how often, as a percentage of the race, is the car actually running at the peak horsepower. All that work to keep it at peak horsepower, and if you're only running it at that peak for 20% of the race, is it worth all that?

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?

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.

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 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

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. Or the Megavalanche bike downhill, the winter version .

Liberty Media and the FIA should recognise that all sport is showbiz and that racers are there to entertain as well as win.

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

Hahaha MCM moog and marty did a cameo!!! I guess you both shared similar cars of choice.

Really cool to see you there, still amazed that I got to talk to you

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

this comment is about the pic of Marty and Moog from Mighty Car Mods and you and it goes something like this: seeing this made me so happy!

Seeing Jason alongside Marty and Moog really caught me off guard there as an Aussie. What were those two doing up at Le Mans, it's like the furthest thing from their wheelhouse.

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 👌

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

Lemans is a blast! Went a few years ago.

Interessant

As a guy who grew with 2000's v10's, and going to the 6 hours of Monza for my first race ever ! I'm soo excited, ultimately, i opened up my mind to the wec championship and i enjoy it more than actual f1 even though i'm a huge f1 fan. So yeah, tomorrow first day in milano let's GO 🤩

Watched this past 24hr of le mans and was actually enjoying it. I was surprised how cool it was. Never was interested in it before.

Epic picture with MCM folks!

On the topic of rotaries and endurance racing... 787b engine in detail, please ;)

@RealEngineering do a Video on the titan submersible

Shoutout to the mad lads at Mighty Car Mods 0:21

I've never been a fan of ultra high revving engines like motorbikes and Formula 1, they just sound way too aggressive to me. Big engines though, like LMP cars or muscle cars... Oh man, that's my jam (the diesel cars from a few years ago such as the Peugeot 908 and the Audi R10 will always have a special place in my heart)

I like the lower rpm growl bigger engines make under heavy load. high-revving whiney engines just seem they are built to expire.

hei man, wold you do a video on methane or buthane/propane powered engines?

Love the video, super detailed. Would love to see more road racing content.

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

Hello Jason! I have a question to ask about the cadillac's LMDh car engine, is that black tank on top of the engine the oil reservoir for the lubricating oil of the engine? Is that the 3D printed oil reservoir that you mentioned? If you see this and answer me then thanks in advance!

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!

Different applications for both series. One maximize performance. Another tried to get performance, reliability, and efficiency in one package

Super interesting video! I am definitely looking to diversify my motorsport intake because of how much I enjoy F1. How would you say the F1 domination eras are different from LeMans being dominated by Toyota Gazoo Racing, Porsche and Audi during the last decade? Or are these new BoP regs meant curb exactly that and they weren't in play during those eras?

Just like in F1, Le Mans eras are bounded by large rule changes. The ultra high cost LMP1 years of the early 2000s led to diesel eras with Audi and Peugeot, which gave way to a hybrid era with Audi, Porsche and Toyota. The current era is partly related to working with IMSA in the US to synchronize some rulesets to make it easier for the many US teams to race at Le Mans. IMSA has knock down drag outs with Acura, BMW, Caddie, Porsche, maybe Lamborghini next year....but yeah, all of that better chance to win gives manufacturers incentive to spend the big bucks to take their cars racing. And the racing is very good.

Toyota was basicly the only one for some time, only this year there was a some good comptetition. And in the years of LMP1h rules they were not using BOP, but Eot similar to F1, fuel flow restriction. They are using Bop for last three years or so.

@@GasperGartner123 Some form of BOP as always been there, Weight and restrictor plates where the tools of BOP. In 2005 They choked us to 4seconds behind the Pescarolos in qualy. with plates and lead in the side pods. Thing is, at full bore, the car wasn,t even pulling a sweat then, and both engine and gear box went from reliable to bomb proof, the other guys not so much. Now BOP starts at the drawing board and the simulation tools are mind blowing accurate!

I don't think Mercedes/Red Bull domination is the same thing with TGR "domination" in WEC. In F1, all cars are practically equal, but in WEC, they have different classes, and only one class that could won in overall race, it's Hypercar class (or previously called LMP1). Now back when TGR is "dominating", TGR practically is the only one competing in that class as they're the only full fledged factory team with full support from Toyota, translate that to F1, the situation back then is like Mercedes/Red Bull winning every race where all other competitors in the grid is either some teams that runs a modified F2 machinery or Haas. And it's shows that now, there is other full fledged teams joining in (like Cadillac, Porsche, Ferrari, or BMW next year), TGR started to losing their dominance, like losing this year 24h of lemans for example.

Nice, I was the 6 Hours of Glen and man the Cadillac sounds like a weapon on track. It's unbelievable

The "vanwall" also runs a high revving NA V8 ;)

I hope you don't mind me asking some questions: 1. Is the engine being a stressed member of the chassis essential to dealing with the rocking couple inherent to a cross-plane V8? 2. If not, does it have counterweights on the crankshaft? 3. If it does have counterweights, how does it rev higher than the flat-plane V8 in the C8.R/Z06? Sorry for being so uninformed, and thanks for reading. Great video!

valve train stability is more important than rotating assembly mass when it comes to higher revving engines. Just look at some old american drag cars and american GT cars, 50+ year old v8's and can crank to 8-9k rpm.

I “love” this guy!!

So, just a question. At 5:47 you see that pit stop, and someone peels something off the windscreen. Is that a thing to quickly get rid of any build up of gunk or something to keep visibility at a peak or is it like a simple protective layer or something? Like, what's the use of that? It seems pretty thin so I doubt it's a protective thing, but I've never seen that before.

Can you make a video about seamless gearbox, please!!!

Jason, how do they enforce the rules in endurance races?

5:45 Glickenhaus and ByKolles(Vanwall) arent using hybrids not necessarily because they don't want to, it's just that they can't afford it

As a nascar fan who watched for garage 56 lemans is definitely a great race, and I liked how much more competitive it is than f1 or indycar

Could you put a mgu-k be on front and rear to maximize regen while still being able to use it at low speed?

Hi can you please explain the engineering behind the 1 stroke engine by INN

I think it needs to be mentioned that it’s not quite as simple as BoP penalizes good engineering. There are still ways to engineer a winning car even with BoP. For example - a car with +10kg of ballast will still have an advantage over an otherwise identical car that has that same 10kg baked into the design since ballast can be added in strategic areas on the car to lower the center of gravity, compensate for aero balance, etc. There’s a reason why the Glickenhaus hasn’t been able to compete with the Toyota and it’s not because of bad BoP.

Wouldn’t they then just penalize you further by reducing your power or something?
