Great move by Alpine. Closing down the engine program means they have little to hide anymore and using what they have for some good press is a smart move!
It's not a mystery how a transmission works. The secrets are in the small details to make a small incremental gains in efficiency and weight for each new year. No race team is gaining any insight by watching this video. It's for the public to do a little Alpine marketing.
Loved the diff explanation - I’m always surprised how often F1 parts are just much lighter, more sophisticated versions of road car parts but that diff is a different league.
@@theairaccumulator7144 Not really, in normal cars it's a matter of cents. Every cent saved adds up quickly. Unlike F1 where performance is objective number 1.

Engineer comment- These videos are great, but a bit frustrating when the B-roll doesn't match the actual topic. At 10:45 they show a close up view of a gear pump which has two identical meshing gears and can be referred to as an external gear pump. It is similar to how a roots blower works. In between the gears where they mesh does not allow oil through, so it is forces the oil to be carried by the teeth around the outer wall. The actual pump hanging from the strings is an annular gear pump which uses an internal and external gear (this pump has two sets). Notice that in the F1 pump the "inernal rotor" (regular gear) has six teeth and the external rotor (internal ring gear) has seven teeth. You can also notice at 10:38 that the pivot hole in the body for the shaft is off center. This locates the internal rotor to properly mesh with the external rotor, which leaves a gap on the far side where the pumping is done. Also notice that the internal rotor is keyed to the shaft, so it spins with the shaft, and the teeth drive the external rotor to spin at 6/7ths the speed of the shaft. The external rotor spins in the pocket in the body. The B roll of the "bevel gear" mesh at 12:56 was painful to see. If you have ever used Lego gears, you know what is wrong with that animation... Again, these videos provide incredible inside views of F1 tech that is just amazing, and I'm grateful to have access to it.
that non bevelled diff is fair enough since it simply shows how the gears apply force to someone with zero mechanical aptitude, yes it's literally grinding gears irl lol
yeah I saw that gear pump footage and thought somethings not adding up. it would've be nice to have some detail on the two parallel annular pumps as they're quite fascinating. amazing info none the less.
This video was hard to watch in general. Alpine put all the effort in basically. The more I think about it the more it makes me mad that this access was given to Scott as I don't feel he did them justice. It was just a rushed mess in parts and hard to follow. Things should be understandable to layman's but this was just rushed to get under 15 minutes. The amount of cuts and fast "explanations" that were edited in that way regarding important things was just painful. With this access to very recent tech he should be doing it justice. I would rather have a quality video that's longer than a shorter rushed mess like this that didn't even match. Wasted the privilege of seeing this or maybe takes it for granted with being a driver. All the tools were there and transparent as well. Could have been really interesting and educational but the editing was poor. All that easy to see setup wasted.
I read somewhere they have issues finding a location. They basically need a long tunnel with smooth concrete lining without anything attached to the roof/walls. And they need to build on/off ramps at the openings/inside this tunnel so the tunnel can't really be used for something important as the ramps would put the tunnel out of commission for most likely weeks, at best days. Tunnels filling all those requirements are extremely rare. I'm not even sure something like that exist. Best option might be to look for some feeding tunnel for some hydro power plant that's under heavy maintenance/repair where the tunnel is either made with a TBM throu solid rock or thats lined because it goes through consistently poor rock. But there are not many of those either.
That note about singapore being hard on gearbox was interesting, if possible could you guys do a video on an entire F1 Calendar track by track and which components are particularly stressed? That would be very interesting to know
That differential is a masterpiece. I truly want a deep explanation on how it works. With no simplified animations. The differential animation you had there that had two straight cut gears meshed together perpendicularly was painful to watch. But overall, great video and hope to see more like it
Man, I could spend a weekend there just looking at the differential. Just amazing design and simplicity all at once. And then there's the 1000 HP going through it all, or to be exact, it's the torque that matters here. HP is just the torque multiplied by RPM.
Another great video, thanks. The cut (10m 43s) from the exploded 6 lobe Eaton style (I know it as) pump to the assembled but coverless gear pump did have me doubting my sanity. Luckily a quick rewind confirmed the situation🙂
Wow! Always loved the transmission rebuilding of my Alfa's and this is a fantastic presentation.....Thanks!!! How all those gears mesh and turn revolutions in to forward movement is incredible.
so nice video , it's a clockwork mechanism , really liked to see how they are build inside , and were the straight tooth sound is "produced" . Sad you not show how the 3rd sprocket gear from Reverse works .
The sound comes from the straight gears themselfs. The Teath have a clearance gap. What your hearing is the movement when one tooth disengages and the next reengages 👍 straight gears have no axial loading allowing for less friction. This is different for helical gears where the there is always a tooth engaged (hense no rattle, no noise) but they do have axial loading and more friction. I hope this helps 🙂 I'm building a V12 supercar 😎
Another important thing to look at with the oil flow is the amount of cavitation on the geartooth caused by the gears running through the oil, which can be even more of a disaster than running minimal librication. Cool video tho! Love these ❤
Yeah that's why they are spraying oil directly onto the gears 👍 straight gears can run on almost no lubrication. As you say, to much oil can damage a gearbox, this is typically on 'wet sump' gearboxes. These f1 gearboxes are essentially a dry sump system, some even have oil tanks built into the casings 😎
Excellent insight into the transaxle internals. It would have been nice to cover why they use a cross-shaft, driven by a spiral bevel gear and driving the differential by parallel straight-cut spur gears, rather than the hypoid gear set of a typical longitudinal road car transaxle or final drive. The answer is that a hypoid gear set provides the required vertical offset, right-angle turn, and reduction gearing in one stage.... but this arrangement provides the same functions with less drag (and resulting heat production), despite needing two stages to do it.
I've done loads of those...in Motorbikes, I'm amazed I recognised everything. Bikes dont normally have a pump tho but they do have Dogs! Its called constant mesh - not like cars at all - here the actual gears are always engaged - its the ring/fork in between them that moves and connects the gear to the shaft via dogs that are a bit like pins that go in holes in the side of the gear where you cant see them. This makes for the fast gear changes until eventually the dogs wear down and it can fall out of gear. Pity he didnt mention the oil - there is enough tech in that too...
2.45 Mclaren breakdown. The Tooned advert on the rear wing was from the Button/Hamilton days... I think probably 2012. Pretty sure that's a Hamilton helmet. Maybe Singapore when Ham retired with a failed gearbox?
Some of those components look like they should belong in a watch, they're pure jewellery, can't believe they can handle 1000 HP at full tilt! Engineering masterpiece!
Simulation doesn't mean you do no physical testing. For one thing, you have to validate the method. Even then, you should always test the final product, just in case one of your assumptions was wrong.
There might be an oil cooler, and the breath pot, usually due to oil expansion temperature and flow during the comissioning of the system the pipes diameter may need to be adjusted to bigger or smaller sizes to avoid overflow. 😎
Awesome and very informative video! It makes me wonder if 1> Can one of those transmissions be adapted to a vette and 2> Would it last a lot longer since it wouldn't be supporting the suspension and it wouldn't see the same amount of stress? It would be interesting 🤔

Love all this stuff. Love the detail and precision. It's mind-blowing. Just a shame that this pinnacle of automotive engineering should ever be handed to a brat like Stroll.
Showing Lance beached in the gravel when talking about the reverse gear is hilarious. He didn't even use reverse and there was an escape road he could have taken to keep going forward.
There's that forum story of a guy that drove spare parts for these gearboxes across europe because flying them out on race day would take longer than driving. He used a Carrera 996 3.4L to do it.
Wow that differential is impressive. How do they even make that part, it has some serious under cut. In addition how do they get those gears in there during assembly. I would love to take that thing apart.
Hola... Excelente video, felicitaciones! y en español se agradece más! aunque en algunos momentos la traducción se adelanta o atrasa. Bueno lo principal de como se hace o materializa cada cambio en la caja de cambios no se mencionó. Plop!
The most interesting thing for me is that the gears are simple spur gears and not helical. When I think of how noisy the reverse gear is in my vehicle, it’s astonishing that these gearboxes don’t scream when under load.
The thing is it's easy to make a strong transmission if it being strong is top priority ,things immediately get much harder if you want it to be light too. Basically the engineering triangle, your choices are strong, light and cheap, you only get to pick two.
12:48 the steering "wheel" display is not public info. So how do the teams handle confidential info? Are there different proprietary levels? Is it compartmentalized need-to-know (e.g. our gear-box expert doesn't know any details about the fuel system and likewise for the aero ppl)? Are there special access developments that some key team members (in different areas, duh) aren't even aware of? What kind of background investigation do you need to pass to get on an F1 team?
Interestingly, they don't care about noise when using straight gears instead of helical gears. We get a whine while in reverse in "our" cars because they are straight tooth. Helical removes the whine, but they are weaker. To understand the engineering with the speed of shifting is amazing.
While the active hydraulic control of the differential clutch is interesting, it is not as unusual as one might think - even GM has use their electromechanically operated equivalent (which they call "eLSD") since 2014 (or earlier?) on a least some variants of the Corvette and other models, and other manufacturers have their own versions What is more unusual is the planetary differential, rather than the usual bevel gear design. They're readily available - Schaeffler supplies these to some manufactures of production vehicles - but still not common. They're used because they are compact, particularly in the axial direction.
I wonder how they manage oil starvation with the very high sideways g forces in prolonged corners. If all the oil is forced to the side wall, how does the pump not run dry? Especially since it's a single pump.
Great move by Alpine. Closing down the engine program means they have little to hide anymore and using what they have for some good press is a smart move!
