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!
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.

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
I remember quite a few years ago before the final race of the season in Japan, I was in Italy to pick up 4 Ferraris from the factory, my first visit and didn't really know where I was going (before satnav) I turned down this country road to see loads of cars parked all over the place, I stopped my truck to see what was going on and spotted this chap going through the trees to a fenced off area, I worked my way through the trees to be greeted by armco around Fiorano Test Track and Michael Schumacher testing, the violence of the gear changes as he came past us is something that still stays with me today, it's utterly brutal how they bang into gear with astonishing force, and the noise omg it was biblical, a day and a moment I will never forget.
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
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.
Man, you the MVP for getting this awesome detailed nerdy stuff to me and everyone else! Good lawd nah, would ya just look at it? Fricking GORGEOUS, bro, beautifully engineered. Hell yeah, brother!
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?
Its not like the old days though is it? When teams were developing things all the time. Like new gearbox casings, new materials, faster shifts etc. Changing gear ratios throughout an event. Its all pretty much standardised tech
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 🤔
L❤VE these engineering videos❣️ Sure, driver strategy and talent play a significant role in winning races and championships. But if they don’t have the technology, and reliability, underneath them they aren’t going anywhere. So many potential careers have been let down by poor equipment.
Not a radically different design. The shape and input an output is obviously different.But otherwise it's just super strong and very good at what it does. It still uses a relatively similar technology. As this is mentioned at 8:58
Its very similar to a motorcycle gearbox with the lack of synchro gears and use of constant mesh, dog gears, and selector forks. If it was bathed in the same oil as the engine its pretty much the same
That's not how a vehicle oil pump works; you're describing an impeller. You also change from showing gerotor internals to showing a gear pump (which moves the oil very differently) when describing incorrectly how the oil pump works.
They have an internal vertical oil tank like a dry sump system so they won't run out or be affected by side forces. The casing is also normally a quarter full of oil so that they have plenty of capacity. It will have a baffle around the pick up to keep the oil in place. Gears are actually quite finicky to lumbricate because to much oil and they just whip air bubbles into the oil. They don't actually need much oil, just a small film. That's why they are spraying oil mist onto the gears 🙂 I hope this helps 👍 I'm building a V12 supercar with the OG zonda engine 😎
Wouldn't it be wiser to remove weight from other parts of the car so that mechanical parts are built more reliable? I mean...I know we are talking about the FIA here but still..WTH?
Really interesting but why the awful, unnecessary and distracting music over voice? It's not a song contest. I've had enough, it's unwatchable, I'm off.
Electric motors aren't engines. Electric motors have their own unique complexity, cost, reliability, and durability issues. There's no such thing as a free lunch.
Do they now? Show me a formula e car get within 25% of an F1 lap time at any circuit. Better yet, let's look at lap times around the Nürburgring-Nordschleife: "The Rimac Nevera holds the record for the fastest production electric vehicle (EV) lap time around the Nürburgring, with a time of 7:05.298" Very impressive, but what about... "The Mercedes-AMG ONE is the fastest production car around the Nürburgring-Nordschleife, with a lap time of 6:29.090 minutes." Ah, but I hear you say, that has a hybrid system. Indeed, so let's look at some entirely petrol driven cars, if which are far cheaper than a Rimac: "Porsche GT2 RS MR 991.2: Has a lap time of 6:43.30 minutes Mercedes AMG GT Black Series: Has a lap time of 6:48.04 minutes Porsche GT3 RS 992: Has a lap time of 6:49.32 minutes Lamborghini Aventador LP 770-4 SVJ: Has a lap time of 6:49.40 minutes Lamborghini Huracan LP 640-4 Performante: Has a lap time of 6:57.25 minutes" In short, you have no idea what you're talking about and can be quiet.
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!
Won't mean they won't be designing their own gearbox though. McLaren uses Mercedes engine but designes their own box.
@@GreenPlasticWaterCanfor 2026 at least they will use Mercedes gearboxes. After that is unknown

This just informed me of new tactics for diff adjustments in sim racing.
Ahh man, thank you for explaining this! Especially the _dif_ bit.. very nicely done for this absolute layman 👌🏼 👍🏼
Cool video. Basically a standard sequential with much better metallurgy and tolerances. Like the engineer said, “much like a modern sports bike.”
a seamless F1 box is much more sophisticated than a standard sequential...
Nascar started spraying gear oil into the Ford 9" diffs , with a pump and squirter tubes built in and on the rear housing.

More on the diff, please - and how it knows what phase of a corner it's in
it's controlled by the ECU, so can be based on car speed, torque or acceleration.
3.000 miles is basically the equivalent of running 75% of the earth radius

They are probably limited in what they can show.This is a relatively recently used gearbox.Design.
i wonder how much horsepower actually gets to the wheels becasue all drivetrains take some of the power away from reaching the wheels
not a secret anymore.

why is the bevel gear a separate gear?
couldn't the final drive gear have it's teeth at 90 and do both bevel and final drive?

Can't be so secret if they let you film there now can it.
I still have no clue how a gearbox works lol
That's not how a vehicle oil pump works; you're describing an impeller. You also change from showing gerotor internals to showing a gear pump (which moves the oil very differently) when describing incorrectly how the oil pump works.
I don't know the technical specs but that pump design is too heavy. There are other alternatives to pump oil with a more compact design.
What adjusts the oil flow for the g-forces in cornering?
They have an internal vertical oil tank like a dry sump system so they won't run out or be affected by side forces.
The casing is also normally a quarter full of oil so that they have plenty of capacity. It will have a baffle around the pick up to keep the oil in place.
Gears are actually quite finicky to lumbricate because to much oil and they just whip air bubbles into the oil.
They don't actually need much oil, just a small film. That's why they are spraying oil mist onto the gears 🙂
