- Let's take a closer look at BMW's LMDh contender.
How did they choose their engine?
Why does it have the busiest engine bay of all new LMDh cars?
Which problems do they have to overcome?

I think your thumbnail needs more arrows
Noted! :)
When a video has good quality like this then a clickbait thumbnail is more a problem with youtube than a problem with the creator
Pls more arrows next video lmao
@@zXPeterz14 i mean, can it really be called a clickable if he talked about everything that arrows pointing to?
@@RCmaniac667 That's actually a good point. I only point arrows to things I talk about :)
Really enjoying the Lmdh videos. I think a lot of people just assume the class is as simple as a motor and a spec chassis, and as a result the class isn't getting the attention it deserves, so having these videos to show the thought and effort that went into designing them really brings home how exciting this class really is. Thanks also for making your explanations accessible for those of us who aren't engineers. Cheers!
You are welcome!
Creating outwash on the tires actually increases drag, but it allows you to take drag out of other parts of the car. So you can end up with a net drag reduction. The scoop behind the rear tire on the ARX-06 is a perfect example of this. They chose to focus on the diffuser over the rear wing, and put the scoop there to improve diffuser performance, so they could run a flatter rear wing. If you notice, the ARX-06 has a more aggressive diffuser design than the others.
When I first saw this car, I liked it so much I ran down to the Alpine dealer.
This is such an exciting championship with so many different brands but as we saw over the weekend the performance is so close
That's BoP, not engineering excellence.
@@X8X8X8X8X8X8X8X8X8X bop still can't save a bad car though
@@ct0560
It can't. Still it artificially equalises cars which are all built to the same regulations, and is therefore very much a violation of the very principle of motorsport.
@@X8X8X8X8X8X8X8X8X8X Unfortunately. There is no more Racing. Only Marketing
Racing Survives because of Manufactures
Manufactures Race to Market
So if BOP doesn't Exist. Then we get no Manufactures or
You get Porsche who will only enter Series they have an rules Advantage in.
Ducati does this too
Thanks for these breakdowns!
My pleasure! More to come!
They look the be a bit off the pace (at least in qualifying so far)
Out of the 4 LMDh manufacturers they have been out of the prototype game the longest so my expectations for them are currently the lowest for all the gtp cars.
It seems like there is way more going on in the rear compared to the other LMDh cars.
Love seeing the Australian business PWR in international motorsport
Hi there,
Could you please do a video explain what does it mean as a chassis? Would that be comprise of only the monoque, or more? How does teams like BMW and Cadilac get to differentiate their car base on the chassis?
What design choices are dictated by the chassis? (Aerodynamics, suspension, drivetrain etc)
How does a manufacture select their chassis provider, what are some parameters to consider?
Quality as always
Could one assume the caddie is more reliable since it has less parts like the turbo?
BMW's engine / forced induction setup looks strangely archaic
looks more than adequate
@Ali Cuntë
Long tubing runs on the hot side towards the turbocharger.
In a BoP formula, driveability and responsiveness matter a lot more than net power, so it might explain the pecking order right now since they're not BoP'ed.
Also from my armchair analysis, how crowded the rear end is and how small the diffuser is compared to the other cars might affect aero balance, not net downforce figures since it's regulated.
Pretty cool how mr dallara designed the original m1, and now dallara is making the LMDH for bmw
Well, they did finish the race...sort of. But man was it a struggle. You could tell that they were not anywhere near the pace. Though there were moments when it looked like they could get up there if they needed to. Clearly they are targeting 2024 like Peugeot did with a limited schedule in 22. They would love to get that 25th anniversary Le Mans win. Honestly, it's probably the only thing they care about. Would be a shame if they pulled out right after...
Where does the radiator air duct located?
Looks cool, but the other cars seem to be smarter…
where do you got the CAD model?
BMW published that
👍💪✌
Is it a flat plane or crossplane V8?
It’s European so I think flatplane
Most european V8 are crossplane as well besides Ferrari etc.
Flatplane because it is the old BMW DTM V8.
"It's beneficial to use a turbocharged large capacity engine so you have the best tools to get the most out of BOP." Have Ferrari, and especially Acura, made a mistake by going with such small capacity engines? (The 2.9L road-based engine in the Ferrari, and especially the relatively high-revving 2.4L modified Indycar racing engine in the Acura.)
Yet **surely** Acura know what they are doing, and have a good reason to have chosen a small, lightweight racing engine -- even if they will need to carry engine ballast that negates any weight advantage? Is there no packaging advantage to using a smaller racing engine instead of a large road-derived engine?
I appreciate that B-Sport is German and is following German logic like BMW and Porsche! 😂 But I can't imagine that Ferrari or HPD would make such an "obvious" mistake **if** it really is such a mistake?
For the inverse, what is the advantage of using a small capacity engine (as long as it durable enough for the 24 hours racing, which Acura and Ferrari seem confident of)? Lower friction (offset by running at higher rpm though)? More efficiency somehow with more boost pressure and working the turbine harder (where the big engines have to waste more energy out of the wastegate, given there is no MGUH on these LMH/LMDh engines AFAIK, and any extra exhaust energy will just be wasted)?
Compared to previous years, this new generation of hypercars is all about using what's already in your shelf instead of developing a new engine like in the olden days.
So they didn't make a mistake, Acura, Ferrari and most of the others just took what was already there.
Peugeot are also using small capacity with a 2.6l V6
@@BSport320 But I have to disagree with your point that larger capacity must be best, else Honda would use their 3.5L NSX engine. So there must be advantages, possibly major advantages, to the small capacity engine! Indeed, perhaps it may turn out to be the optimal solution in hindsight while BMW and Porsche struggling to make their overly large engines competitive? Honda are obviously going for the win in IMSA and hopefully in WEC and Le Mans too.
Even with the engine ballast, perhaps the smaller Acura engine allows for significantly superior packaging and aerodynamics?
@@TassieLorenzo The engine in the Acura was originally made for the new Indy car regs which got delayed, that’s why it’s being used
@@dsr_2443 Agreed, but they are hardly going to use a smaller capacity engine if it gives them an overall disadvantage, no? So there must also be advantages to using a smaller more stressed engine -- whether that's packaging for better aerodynamics or that it's more efficient (more laps per stint or that they can carry less fuel weight at all times, even if there is a BOPed restrictor on refuelling rate), right?🙂
HPD (and Peugeot and Ferrari) have not read the rules then decided to do anything that would give themselves any kind of disadvantage after all! They are all there to win, and know just as much about engineering a racing car as Porsche or BMW after all, or indeed Toyota with their engine capacity somewhere in the middle.
I'm sure the former three would have found a 4.5L V8 and stuck twin-turbos on it, if that was going to be any kind of advantage!
Love the videos! - hate the intro sound. Its a great engine note, dont get me wrong, but damn its noisy and disturbing for no reason. It makes my wife hate your videos... ;)
OK, let me know which car sound your wife likes :)
@@BSport320 Porsche Taycan Turbo S 😁
@@BSport320 919 hybrid engaging the e-motor :D
I dont think BMW LMDh is going to work well, at least this year
🤓
it's a shame that these big manufactures like porsche or bwm, without any significant race program at the time, chose the easy way unlike the real LMH manufactures.
