A great video, as always! I love how much you go into detail for these videos, showing both the actual part as well as animations of how it works in the engine.
Great video! MGU-H seems like a powerful environmental and efficiency tool for combustion engines. Part of the large reason that it is being removed was it is a cost that has no practical application on road cars but as stated in the video, it is finding its way into upcoming vehicles and the electric turbo is already in use on road cars. I can't believe that F1, a platform that prides itself on being cutting edge is banning this element. Even with increasing the electrical energy store for the next engine regulations, you are still missing out on the efficiency that this device brings. With F1 promoting how it is reducing waste, funny that they don't want to make their engines as efficient as possible. They could always put a *ahem* "cost cap" on this device or state that you can only use let's say 1 MGU-H per season and the design is locked for 3 years with only materials updates available as repairs, to give durability if needed. Just a shame that F1 always states they move forwards but in this, they are moving backward.
This is the greatest automotive invention of our time. It's disheartening that F1 are turning their backs on forward thinking engineering, F1 should be about the pinnacle of engineering and technology.
A shame that the coming regulations will remove MGU-H because who needs efficient and smart solutions in the "pinnacle of motorsport" that's apparently going "net zero"
great to see mercedes cascading this technology down to the masses! I wonder what this technology can do to improve the thermal-efficiency limits of combustion engines?
Very informative video. Thanks for that. I'm scratching my head over the fact that you stated in the video that MGU-H improves brake thermal efficiency and as a result improves sustainability. If that's the case why is it being phased out in 2026 engine regulations given you also said that the tech is finding its way into road cars ?
The irony that just as this tech reaches maturity enough to transfer into road cars, it's about to be removed from the PU regulations for being considered too expensive and complex to be useful to car manufacturers...
surely this is one of the best areas for future efficiency gains from combustion engines?? I hope F1 reg's change in the future to allow this. love to know how much relative power they get from this device? With the conversion to electrical components, the combustion engine will begin to look more and more like an "electrical generator", rather than mechanical output alone. Also, wouldn't the fan in the MGU-H make the exit of exhaust less efficient, so decreasing mechanical power?... but the gains from generation must be worth it. I would love some more detail on this. :-)
I think the continuous development and improvements on MGU-H technology through F1 can be very useful for road cars to improve performance, efficiency and sustainability. Unfortunately, it will be banned in F1 from 2026 onwards :(
The push from various governments globally is electrification. These governments want to ban the ICE platform in 20 to 30 years along with fossil fuels. 🙄🙄🙄🙄🙄🙄
So this is basically the air intake correct? The turbine is spun by exhaust, and it’s electronically spun. The air it creates is then cooled by the intercooler at the end and slammed into the cylinders.
just to confirm with any knowledgable person here, so MGUH only pre-spool the turbo to reduce turbo lag and does little to nothing on the top end of the RPM? can't wait for a video on the MGUK becuase I really want to know how it send its power to the driveshaft, love this stuff
It can act like a "supercharger" to supply perfect boost at any time, but when the engine has enough boost, it can send some power to the wheels (MGUK) or the battery. Primary role would be perfect boost management, then charging the battery or powering the MGUK
@@alexjohnward alright, another question, how does the MGUK send power to the wheel? like is there just a motor spinning the wheel in addition of the driveshaft and just make it spin faster? or is there another way
@@SW4GK1NG The MGUH spins, primarily delivering boost to the engine, but when there is excess energy available, it starts generating electrical energy, which travels down the power cables to the MGUK, which is basically just an electrical motor coupled or geared to the crankshaft of the petrol engine.
@@alexjohnward ah, thanks for the MGUK explanation, I was always wondering how the MGUK send its power, I guess I just never thinks about it being geared in as well, tysm
But isnt this reducing the turbine speed when charging? Is it overall more efficient because adding turbine resistence (compressor + MGU-H) some how increases the amount of work done by the exhaust gases with some added resistence?
What I want to know is if hey could get rid of the turbine all together. Then they could have straight exhaust and keep a compressor powered by the MGU. In other words MGU powered supercharger. The cars would be so loud!
That would be possible - but one of the points of the MGU-H is to improve the efficiency of the engine by harvesting waste energy from the exhaust. This is one of the key reasons the Merc F1 engine is more than 50% efficient at turning chemical energy in the petrol into kinetic energy pushing the car forward (a typical road car is only 30% efficient). If the exhaust turbine is removed then more of that exhaust energy is lost, and you get less efficient. Whether you want an F1 car that is more noisy, or more efficient.... well, that's not an engineering question!
How can you add energy/interface with the crank being turned by the combustion engine without the grinding each other out if they are not at the same speed ( like gears destroying each other)?
The MGU-H in this video does not engage with the crank at all. It engages with two turbines - one in the exhaust, which helps spin the MGU-H, and one in the intake system, which compresses the intake air. It is the other motor, the MGU-K, which interfaces with the crankshaft. This is connected to the crankshaft at all times, so it is always spinning at the crankshaft speed; sometimes it is harvesting energy (under braking), sometimes adding more power in (under acceleration). I'm sure Hywel will explain it more thoroughly in the next video.
When you use the MGU-H as a motor, you are not only sucking more fresh air but also exaust gases. Does this have an impact on the combustion process or how is it regulated?
Turbos don't suck in exhaust gasses buddy, on the hot side of the turbo (turbine) the exhaust gasses pass over the turbine wheel to spin it before passing through the rest of the exhaust and out to atmosphere behind the car. On the cold side of the turbo (compressor) the turning force from the turbine turns the compressor which sucks in air through the air box/intake above the drivers head, compresses it to many many PSI in a Formula 1 car, forces it through the charge cooler core to cool the air down and thus further increase the density of oxygen in it, then forces it into the engine to be burned in the combustion cycle. Many road cars run around 14psi of boost, my fettled weekend car makes 29psi of boost, I believe Formula 1 cars are around 80psi of boost, knowing how it all works with boost its mental to know just what they've managed to achieve.
@@bash83845 Totally agree, but only if you use a "normal" turbocharger. As explained in the video, they can accelerate the whole unit, by using the electric motor which is located inbetween the hot and the cold side and connected to the shaft. By that, a higher mass flow of fresh air, than usually possible, is generated to prevent the turbo lag.
The MGU-H in the middle uses overboost ie on the rundown to charge the batteries and is able to artificially spin the central shaft to spool up the compressor wheel quicker thus eliminate lag. None of that will result in sucking in exhaust gasses.
@@bash83845 Yeah, but when the shaft spins, obviously also the turbine wheel (hot side) spins. This reverses the effect of being accelerated by exhaust gasses to accelerating exhaust gasses and results in sucking them, doesn't it ?!
@@alexisjelly5597 - the only "production car" to have this technology is the AMG One. Not everyone can afford this multi-million dollar car. So you can imagine the service bill and maintenance on this car will be quite high. I'm being sarcastic about the PHd but nonetheless the bill would be like going to a neurosurgeon.
I would think that you could engage an e-machine that directly drives the wheels additionally. This could reduce the effect of the turbo lag. At the same time, you could use that e-machine for recuperation. It would basically be an HEV on steroids
Great video, but I am not sure such technology would ever hit the road cars, as it's very expensive. Not that I am against it if it was feasible and worth it.
Regarding BREACH - Demand points deduction EQUAL TO % OF BREACH committed - BOTH DRIVERS AND TEAMS! If that breach % is just "miiiiinooooor" thingy than EQUAL DEDUCTION of points surely isn't overreach but actually FAIR
Heat is slightly misleading I suppose. Really it is using the pressure and flow of the exhaust gases to turn a turbine. The heat of the exhaust does contribute to this, and the exhaust will be slightly cooler as it leaves the turbine. This spinning turbine is then connected to the motor/generator, so spinning it in generator mode generates electricity.
This is an amazing piece of tech, surely they would never do away with it………oh wait. Formula one is going backwards in my opinion, they should of just made everyone use a supplied mgu-h, or come up with another way to keep it.
The MGU-H is my favorite piece of technology in the whole F1 package. And they're banning it. Based on the easy duty cycle of road cars, it may not be best used there. Marine applications or heavy duty trucks would be better.
And what a shame that it has been removed in 2026 to appease and make it easy for Audi and now not Porsche to join the sport. Create great advancement and efficiency and then take it away.
Why do they have wastegates? Doesn’t the energy of the turbine shaft get transferred once boost is no longer needed. Or does it not even need that extra energy so it just gets outgated? I’d much rather this be a Netflix show than the edited drama that it is.
Jesus, could these vids be any more pedestrian? You aren't actually explaining anything. You're just naming components. So, so many interesting things to talk about when it comes to these things. Who is this aimed at? Kindergartners?
It's a great piece of tech but I'm glad it's disappearing. Drivers trying to control boost coming on hard will be a spectacle not seen since the 90s. I'd go one step further with the new regs for 2026 and mandate twin turbos for better sound. One turbo has proven to sound terrible.
I'm far far from a merc fan but no one explains f1 parts in detail like they do. This is an outstanding series
Yeah, why other teams don't do the same thing
All the Lewis haters start there comments with “ I’m far from a merc fan” why is that’s relevant? Who cares

Mguh is new and looks important for future of net Zero aims. Why did u agree on scraping this rather than impeoving for future road cars?
Shame this unit is being removed so a rival car company can compete.
Putting a more simplified version of the MGU-H with the c43 v6 in the new c63S would have been less offensive to alot of people than the 4 cylinder
Just make sure next year’s MGU-H is better

No current AMG owner wants an electric AMG.
why don't you use the mguh on trucks?
Power output is not regulated? I thought the entire electrical system could only deliver a max of 161 hp?
The power that the MGU-K can deliver is regulated. The motor in the MGU-H can be as powerful as the manufacturers want it to be.
