I got to see something really cool. I got to open up a modern F1 gearbox and see how it works -- and these things cost upwards of £250,000 each, with the F1 teams spending about £7 million a year on them.
So, of course, I wanted to see and touch the materials and understand exactly how a Formula One car changes gears - from when the driver pulls the paddle through to the gearbox selecting the next gear.
And how they work is actually pretty simple, and, incredibly clever all at the same time.
So, a few weeks ago, I was invited to TDF - a company that restores old F1 cars for private owners - and gives old F1 cars a new lease of life.

#Formula1 #Gearbox #Gears
Even though I no longer turn a wrench due to physical issues, I still love learning about stuff like this. Truly fascinating.
hope you get well soon mate :)
Same here my friend, I have 20+ years experience but still work on my own car here and there.
Same here. Miss building cars (back injuries) but this guy is so interesting to watch. Makes me long for those days again
Get well soon❤
I never do bc im just too incapable and enjoy learning about it aswell. I think working on cars and learning about the mechanics of them are two separate things.
I’m always amazed at the narrowness of the gears, considering the power they have to transmit ❤
I would disagree if those gears were designed for the V10/V8 era because low torque engines. The hybrid engines have 3 times more torque but it seems that the gears aren't any wider which amazes me as well.
This is why they are straight cut. Road car gear are not straight cut to drastically reduce noise but as a result need to be thicker and heavier to prevent skipping and the inherent sideways torque of angle cut gears. Even in multi-thousand Nm industrial engines the straight cut gears are thin - this predates anything similar in F1. Indeed, 1920s busses had them, but they were not seamless and in a "crash" configuration with no synchro drive dogs.
@@SocietyUnplugged But, the gear width is still based on the torque the gear transmits... for strength and durability. 1st gear must transmit much more torque and is wider than say 5th gear which sees less torque (due to gear ratios). I believe beryllium is still banned (health issues) but there are some OMG alloys out there that have taken gear strength to new heights... as well as costs... material and machining. Grumman holds the patents on some very exotic alloys. My contact won't say who is using which ones, only that they are being used. This is where the FIA's stupidity on "cost cutting" becomes painfully obvious. Ideally, in racing, you want just enough strength to last the race and 50 more feet. But the FIA saw that as wasteful and threw in the multi-race engine and gearbox rules. So now the gearboxes (and motors) have to last longer... but to get there they had to go to more expensive materials and machining costs. So no money was saved but the FIA can put on their addlepated "Green" smile.
The shaft spacing, when wider apart, means the chord line of power introduced to the gear teeth, is flatter and the force is therefore along a thicker part of the gear tooth. Also there are several teeth always in engagement, lowering the amount of torque loading on each gear tooth.
Materials man
They could buy the house I'm renting with that transmission...
My current monthly rent is more than my parents paid for their first house. I am sure rents will soon catch up with gearbox prices.
@@bertram-raven so depressing that that's actually plausible.
Or fill up your gas tank 1000 times. Ohh, wait... No, sorry. 999 times.... 998.... 997.... 996....
I do work for the company that makes the microhydraulics for these. Super cool to see.
Do you know how the timing of the gearbox works ?
@@RogerKeulen I do security, not engineering
Im far too busy lubing my shafts, prior to sliding said shaft inside the dripping wet (with oil :) ) bearings.
😂😂😂😂😂
If inflation goes any higher, it's gonna stress the hell out my member, as hes gonna need to start making LonelyFans content... Hahaha!
What happened to your "driving upside down" challenge?
Costs
Not got enough moneys
He fell down and didn't wanted to be featured in a FailArmy video ;-)
They needed a car with downforce that's 2x car weight + the power to keep it going that fast to maintain downforce, as well as a round enough tunnel, & the car being somewhat disposable, so a prototype doesn't really work.
Clearly got a very classy audience as I can't believe and disappointed that after a quick flip down the comments nobody has made a "stressed member" joke.
I didn't go there until I read your comment, get your head out the gutter! 😂
“Stressed member with its load going through it”
Because it takes a " stressed member" to be into this kinda stuff...
@@MrHiBeta Legend! :D
Fnaar Fnaaar.
Great video and I'd often wondered how the seamless shift worked. It's cool to see that the gearboxes are still effectively an old school manual box, with a lot of newer technology incorporated into them.
Simplicity is king, and manual will always be the king of simplicity
This video doesn't show how the latest gen seamless shift actually works - it only shows a dual selector drum gearbox which aren't used anymore. The newest version of seamless hasn't been publicly shown, but there are patents showing how it was designed. It completely removes the selector forks in favour of a hollow drive shaft with a mechanism that essentially controls the gear selection through the gear hub itself rather than using shaft mounted dog rings as previous gearboxes do.
It's apparently even faster than dual selector drums, with the downside that they need rebuilding more often. If you want to know how the mechanism likely works (again, there's no public info for current gen seamless), there's a few videos on here that demonstrates the basic operating principle.
I have no freaking clue after watching all of that, but thanks so much for taking your time to explain it. At least I understand a little more and I can appreciate more the design/engineering these guys make. 💙
Motorcycle was the first thing that came to mind.
So it's basically a double clutch gearbox but if you get it wrong you don't burn a clutch but the gearbox explodes 😂
pretty sure it would break the car in half.
but it's much much much much faster, and lighter
Complete engine management prevents an explosion. Some 'manual' electric shifting street cars are now using this technology.
No. There are no synchro rings, and there's only one clutch, and one input shaft. It's a "traditional" sequential gearbox, like in a motorbike, with extremely precise controlling, made of top of the line materials.
One clutch..two barrels..why do they need extra weight on dual clutches,dual shaft..just put one more barrel..with no synchronizer..it is hard change..like
My first career many years ago was as a heavy equipment mechanic....I used to remove these massive transmissions from time to time for repair. Its very surprising to me to see how simple and light the F1 transmissions are and that they can withstand the shifting at such high revs and not blow apart. I wonder, how long do they actually last ?
They can last 6 races (p3 to quali, to race) or more, ~400km per weekend = ~2400 high stress kms.
@@chiefdenis very cool ... 6 races , thats pretty good !
You may remember they pointed out an oil pump early in the program which helps cool the transmission and insure better oil distribution/volume compared to similar transmissions that just have the gears sitting in the oil to distribute it. Most likely helping longevity of the trans. Something I didn't realize was the two shift drums. I thought they had two separate clutches and gear systems that were independent of each other. One for odd and one for even gears. This way they could shift independently. Shifting delay between the two could then be determined electronically and easily tuned. With the approach used in the video requires just another drum like a self playing piano. Less complicated and less weight. Very cool.
this gearbox is just perfectly similar as to how underbone motorcycle gearbox works,
the difference is, the hub, in which on motorbikes it was one with the gear,
and the selector barrels being single shifting drum on bikes,
i tought F1's gearbox was extremely. unique in mechanisms too,
glad to know, simple yet effective designs prevail 👌
As an industrial mechanic, I have been working for almost forty years in a company that manufactures gears and gear teeth. It is incredible what has happened in development since then! Gears used to be heavy and clunky. Today they are much lighter and have better torque. The manufacture of gears is a brilliant world in itself. Just by using much better quality controls and technology, you can improve the weight, service life and efficiency immensely! I love this job!
Pretty much looks like a motorcycle gearbox very cool. Long live the dog box 📦 ❤
Todays 1000cc Sportbikes are more complex than this. A 2024 BMW 1000 is an astonishing piece of engineering. The IOM TT lap record is on a Superstock bike. A kid can buy the fastest bike on Earth with fast food wages.
They all use F1 technology. Combustion tech really moved on for 4 strokes due to F1 secrets or evolution going over via the likes of Honda. Before this 2-strokes ruled. I's love to see F1 move to 2-stroke motors and develop those.
I don't consider 20+ thousand dollars to be fast food wages but I guess it would be possible to buy one if they're still living at home with the parents.
And spoiler alert, the fastest (production) bike on the planet is the Kawasaki H2R which cost 50K...
I knew it, I knew there were gears in there.
To those who are asking about the gears, here are a few items. First and foremost, gears transmit torque, power is merely the rotational speed times the torque. Why torque? Because a force is transmitted from gear tooth to a mating gear tooth. The force times the pitch circle radius of the gear is the torque. Now why are the gears so narrow? The force that can transmitted depends on the fit between the mating gear teeth. In gear design theory, the objective is to have a rolling contact along a line of contact between the two mating gear teeth. This line of contact depends on the finish tolerances between the gear teeth. Obviously a 100%-line contact is preferred. This takes a high degree of precision and close tolerances. The closer the 100%-line contact is reached the more torque can be transmitted without overstressing the surface of the gear teeth. The gear teeth are also heat treated along with a surface hardening in order to allow higher loading stresses. Also, fatigue life is part of the design of the gear. I am sure that these gears are very life limited in that they may only be safely used for one particular race including the trials and qualifying. This will also reduce the necessary width of the gear. One last item is whether or not, the gears are designed as hunting or non-hunting gear sets. A hunting gear set has different teeth meshing with different teeth on each revolution of the gear set. A non-hunting gear set has the same teeth always meshing with each other. In high torque applications, non-hunting is preferred in order to ensure the best fit. Anyway, that is Gear Theory 101. HTH
Gears ⚙️ aka spinning levers 😮
@@ianmangham4570 exactly!
Considering the amount of power transmitted, I'm most impressed by those drive dogs which take as much force as anything in there and are the smallest part. Impressive stack of friction discs in the clutch of such small diameter.
East to see how just a brush of a barrier in practice makes the mechanics see stars knowing how big a job it is if that housing is cracked.
Yep love the tech, no one else does it so clean and understandable
Tractors have had "stressed members" for years. With straight cut gears and I'm told the crown wheel and pinion are straight cut too, that thing would need a loud exhaust noise to drown out the transmission noise.
Things i didn't expect to see in this expensive f1 gearbox video: Lada 2107 in garage 54))😂
Вот теперь думаю ты русский или смотришь в английском дубляже/Now I think you’re from Russia or you’re watching a dubbed video

The MotoGP seamless gearbox is even more fascinating, it's different in concept
yeah, this F1 gearbox isn't really seamless.
@@Mudux i think they use this method because I think that is more reliable and they really wanted just a quicker and smoother shift. In bikes the main target is to cancel the "kick" from the tork of the shift, that can unsettle the bike a lot more than a car. But anyway from the beauty of engineering I think MotoGP wins 😊
@@LucianoBenvenuto-vy6vcTill today I have never seen any video which even remotely covers what kind of magic they do inside MotoGP boxes. The tech is more top secret than some national secrets..😂
@@srinitaaigaura unfortunately I don't remember where, but I've seen it documented a couple years ago somewhere.. and if I'm not wrong Ducati has presented a patent here in Italy for a seamless gearbox for street bikes (I believe for possible use in SBK) It would be very expensive but I think give it some time maybe it would become reality someday
The heck? Motogp boxes aren't the same as mass production superbikes? I need to go check this out.
As a mechanic and F1 fan i love this type of content! Thanks!
Silly question: Where did the term "Dogs" on the rings come from? Love your insider access to this world.
"This word usage is a metaphor derived from the idea of a dog (animal) biting and holding on, the "dog" name derived from the basic idea of how a dog jaw locks on, by the movement of the jaw, or by the presence of many teeth"
From Wikipedia
@@Sakehime the fact that you credited Wiki for that says alot, you a real one
To me this looks like an overcomplicated motorcycle transmission
Good job you don't design F1 gearboxes then! TBF, almost all gearboxes work on exactly the same principle, meshing different gears to give different final output, so they do all look the same. For example, motorcycle gearboxes just look overcomplicated watermill gear systems.
Thanks for those informations ! :D
I'll take that as direct knowledge for my formation next year to become a race car mecanic (at le Mans FFSA academy) 😁
(man i'm so happy to be selected as a student there and i think channels like this are a part of it)
So..... Its basically just a fancy riding mower gearbox.
Anybody who has stripped and rebuilt an old motorcycle gearbox (e.g. the AMC/Norton box from my 1966 Norton 650SS) would recognise much of that box, selector cam (although on the AMC it's a slotted plate) with multiplate clutch, but without dog rings (they're directly on the gears), reverse, and the dual selector cam.
Or a riding lawnmower transmission.
Any Japanese bike does it better.
@@frogandspanner I thought I knew moto gear boxes well until I rebuilt a Hodaka transmission. Whole different way of thinking.
Motorcycle tech from the last 55 years
That would take it back to British bikes?
Very similar for sure. I have had hundreds of motorcycle and ATV engine/transmissions apart and they function just like this, except the actuation is manual and not hydraulic. I know these cars are light weight and made out of the best materials, but the size of the gears still suprise me.
By all means please do more of this type of content Scott!
Really enjoyed it.
At first I was a bit surprised that F1 cars still have an actual reverse gear. After all, why not just use the hybrid system for that, and reverse on electric power alone. But then I realized where the MGU-K is placed in the whole power unit......yeah, that's not gonna work...
But impressive piece of angineering, and very cool to see!
I was confused mid way but i realized this is a decade old gearbox.
Maybe a caution or warning would have helped because this is not current tech
This is by far my favourite recent video! Great technical insight :)
Genius engineers could have looked to farm tractors weher the engine and gearbox as stressed member is standard, probably from their first inception.
That was a great vid. I didn't expect the pitch of the gears to be that coarse in F1. Also you can definitely tell how 3d printing is revolutionizing machines, casting that housing, or machining it from a billet would be incredibly difficult by comparison.
Maybe I missed it, but what material are the gears themselves (not the gearbox casing)?
Steel. Steel is still the best for gears and it's actually mandated in the rules to prevent teams from spending a fortune trying to come up with something better.
I really doubt that this is from a modern "seamless" shift F1 transmission. Having a seamless shift is something extremely difficult to achieve because you cannot instantaneously apply torque to a higher gear, there has to be a way to dampen the torque. This gearbox seems way too simple for a seamless shift transmission. I understand teams used to spend insane amount of money to achieve that, and this just doesn't show in this transmission. Honda has a technical document somewhere on the internet where it's publicly available, where they show how their design works, and this from like 20 years ago. It's extremely complicated. I seriously doubt that modern ones are as simple as shown in this video
Modern ones are that simple, that's why they work instead of blowing up like they used to. The complexity is in the hydraulics and computer controls for it, not the mechanical design.
That is actually crazy, engineers deserve way much more credit! Hopefully one day i will become one myself!
Yup, the unsung heroes of F1
its a straight cut dog box.. pretty much the same as a motorbike gearbox
Pass it on to Brian Garvey, and watch his vids. He’s an engineer and loves explaining all the details.
Dude omg yes!
That dude rocks, for showing such intricate and nerdy details.
Hello, fellow nerdy car lover. There's at least 2 of us.
Hah! 😂
F1 gearbox is simpler than the 4-speed manual one on the Pinto that I took apart to fix during high school. They got rid of the synchomashs as F1 mechanics can't wrap their head around how they work.
Synchromesh is old school tech.
Not the same kind of gearbox. This is basically a very expensive sequential manual out of a motorcycle. You don't need syncos as this is a constant mesh gearbox. you can't just pull the bike/F1 car in neutral anytime you like. You have to shift to that point where no gear is engaged.
@@davidhill850 Ha ha, I was just being facetious. I had motorcycles and now have three race cars with sequential gearbox, one like those in F1, with clutch pedal on the stealing wheel.
what utter rubbish , if you actually knew how synchro works you would know it baulks with more than about 8000 revs , crash boxes dont care and are the only ones that are happy at 18k
Wow! Loved this content, really super interesting. Thanks Scott.
This is somewhat different than the gearbox on the Tyrrell 022 that I worked on. The cases were made of magnesium and there was only one selector barrel.
I bet it's gears!
surprised to see that a f1 gearbox is essentials a motorbike gearbox with a actuator.
Very nice explanation. Although you forgot to show the 1m spacer between engine and gearbox that the cars have today😅
I can’t believe how small the clutch is, it looks like it belongs on a motorcycle.
My honda cup 100 EX5 dream have the same technologies.
I have 0 mechanic knowledge but these types of videos are very interesting. I love f1 and its very cool to see the inside of the cars :)
I remember when the seamless gearboxes come out on MotoGP, it was fashinating and not many information were released about them. I thought it was something way more complicated than a simple syncronized double barrel system.
Esa tecnologia antigua viene de las motos solo incorporar el servo es lo novedoso 😅
I kinda don't want to watch any of your videos because you blatantly ignored everyone outside the U.K. on your "drive an F1 car" malarkey. And you never addressed it. Nor did you do anything about it.
en principio es lo mismo que la caja de cambios de una motocicleta
And in the first lap out of the pit's you need to program these two rotating bars. That's why Max had to go to all the gears in Hungary on a wet track and made a mistake going to the grid. Thus making everything going in sync. So, it's pretty precise how they to that. Precise enough to change overnight or temprature cycle.
Love teardowns and explanations of cool racing tech, more of this please ❤
It would be a dream to own and work in that kind of workshop. Mad respect to them!
An Xtrac gearbox - legendary transmission company. Great video!
Happy to let you know that I like this content and would like you to make more. The engineering in F1 is endlessly fascinating.
there are 8 gears right.....!
I almost didn't watch this but I LOVED it! Thanks man, only the most intelligent & knowledgeable can learn and teach simultaneously. Big ups
Brilliant. Love to see more. My head kinda hurts but I think I get it.
How is the synchronising done? That gearbox is no different really to my 1930s car one but when I shift gears I need to rev match manually so the dogs engage. When I change gear I need to match the engine revs to the road speed for the gear I am in. Modern normal cars have synchronisers so it happens mostly automatically. How does it work in F1 cars? I guess the computers can vary the engine revs fast enough to match the speed of the wheels?
Insert video of exploding gearbox here: 11:53
In the billiards diagram @6:09 ... the 3 ball (red) would miss due to contact induced throw (CIT). Look it up.
Great details! Really cool to see both inside and outside of the gear box.
Can they do weld repairs to the 3D printed titanium gear box casing? Like if a mounting point got cracked or something like that...
What a video you put out thank you very much!!! Great job explaining the gearbox collaborating with TDF 👏🏼
300k euros for a gearbox that handles only around 1000 horsepower... I bet it is cheaper to get the gearbox of 1600-1800 horsepower Bugattis, Koenigseggs and the likes... which make a lot more power and torque than F1 engines...
I wasn’t expecting the transmission to look like a regular sequential gearbox at all.
So, it's not a modern F1 gearbox. Modern gearboxes aren't anything like this anymore. 3D printed titanium? Didn't know there was such a thing. I know there is CNC machined, but 3D printed?
I mean its a dogbox no ? Pretty simple
It's amazing that the dogs can transmit all that power, being as small as they are. Unless I got it wrong - they are a very high stress part in the system.
Never knew F1 gearboxes were this full of tech and precision. This video was incredibly informative and well put together. The seamless shift technology seems like a game-changer in the sport.
I know it's insanely expensive, but I'm surprised we don't see more graphene being used in F1 engineering. Again I understand is not cost effective, but considering the lengths F1 goes to for a tenth, I find it odd it's not used.
My stressed member also shifts gears in 0.02 seconds
Bro i don't know how this didnt have any likes 😂
Really interesting - thanks! Old school names -"shift drum" and "shift fork" The Dog engaging is that "clunk" you hear when shifting a motorcycle into 1st from neutral.
Driver 61, yours is one of a select few F1 related channels that is not a mess of hyperbolic foolishness. It is factual, not subjective...and even more important...INTERESTING. Thank you for a job well done. Live long and prosper.
In formula1, who fabricates these? The same makers of the power unit? Or is it the racing team?
Looks uncannily like _any_ motorcycle gearbox.
Very similar but much stronger and lighter
Kind of surprising to see spur gears in here. Im a gear cutter, but not in the automotive field. Wouldve thought helical gears with a smaller pitch would increase contact ratio, reducing wear on the gears.
The spur gears are less drag and less thrust loading.
@@NBSV1 interesting, i wouldn't of thought of that. Backlash pretty loose as well? Im used to about .004" backlash for what i do.
@@bensalyer2652 I don’t know their exact specs, but they’re probably relatively loose. It’s part of why they don’t drive slow very well. Low inertia with no cushion and loose clearances makes it want to jerk and buck a lot.
@@NBSV1 thats makes sense. Thanks for the insight
The gears need to spin freely. Helical gears would put pressure on adjoining components.
Weird. I would have thought they were more sophisticated.
I deal with these all the time in motorcycles. Bikes have been like this for many many years.
Best gearbox made!!!!!!!
I didn't expect it to be so similar with a lego technic gearbox
The thought of trying to recreate the power unit and trans assembly with Lego immediately crossed my mind. Not sure how you'd go about that many clutches. There are pieces that function similar, but I think actuating six consecutively in the same manner would be a feat. It would likely get too bulky to stay within scale. Could be possible to show a seamless shift style setup, but in two or three speed version. Lego definitely has plenty of existing licensing now, with a lot of entities involved with formula 1. Can't tell you how happy I was to see a Lego brick printed with the words Powered by Honda. I'm going to check into this. Wouldn't be surprised if it's been done already lol. If somebody can build a damn near 8th scale version of the ra272, this shouldn't be that difficult. Just out of my league
@@heinous70 it wouldnt be as compact and mabye not even posible because there are only 3 pairs of gears that need 3 studs of space and have a clutch variant, thats why many lego gearboxes have two axles spining at diferend speeds
@@crazytechnic486 I've never noticed that. But then again, I can't say I've ever tried to build an actual working transaxle. I'm assuming that's where the complication comes. The axles being in that close proximity. I hadn't even thought it through that far yet LOL
@@crazytechnic486 I didn't notice your name until after I had posted the original comment
A Renault engineer used Lego to create the Multimode Hybrid Gearbox...
Amazingly the gears in my old Triumph Bonneville 1973 are famous for getting false neutrals all the time, ie. for example shifting between 3-4 using the clutch you could end up in a false neutral. However - if you hard clutchless shift up through the box just dipping the throttle as you shift, it NEVER gets a false neutral and shifts seemlessly and fast. This is because that is how the box ended up being made to do for like the Isle of Man and other road races. And it does it perfectly. Anyone ridng and getting falsies, isn't going hard enough !!. Hahaha.
Yup, surprisingly simple in operation. Very much like the trannies in my motorcycles.
I wonder what level of detail Brilliant gets into when it comes to gear design. Decades ago, designing a gear set seemed to take a lot more into account, as much of it has since been complimented by not only 3D modeling and the subsequent modern CNC/manufacturing processes, but also modern FEA software. When I first started doing gear design, much of it being plastic gears, I entered at a time where I had to learn about approach action and recess action (AA/RA). Those equations helped me design gear systems that minimized wear. Then, I had to run through some basic stress calcs. Now, AA/RA isn't such a big deal (more modern engineered materials and those 3D CAD/CAM implemented tools), but I don't doubt it can still play a part in design of gearboxes, including metal gears. Since they're trying to minimize weight, rotational mass, while having a defined life (which isn't something like a consumer or industrial system has to deliver), properly accounting for these nuances can really trim the design to an optimal performing system.
Here, as everywhere, market forces determine the price (supply and demand). Diamonds are expensive because they are rare, and bread is cheap because it is not rare. Manufacturers precisely calculate that this is a component for an F1 racing car, making it a product with a 3x-4x-5x markup. (The same goes for sailing/boating; manufacturers know that the owners are wealthy people... the manufacturers are not stupid.) There's simply a huge profit margin on the product.
Mirip ama transmisi sepeda motor. Bedanya cuman kualitas bahan sama mekanisme barrel shift nya doang bro
This is very similar to what Honda is using today in automatic transmissions for motorbikes such as the NC750 or GoldWing, for example.
The Dual Clutch system. Two clutches, one on each shaft. On one shaft are the first, third and fifth gears and on the second shaft are the second, fourth and sixth gears.
In other words, if the engine is running with the fourth gear, located on the second shaft, the clutch on the first shaft is ready to engage the third or fifth gear.
I own the NC750, and I can say that the shift and transition is impeccably immediate and almost imperceptible.
In addition, the transmission is fitted with an anti-rebound system to prevent wheel lock-up in very fast downshifts, especially in sport mode, or by using the handlebar paddles.
EDIT: UNSUBSCRIBED!
BIG 👎 because I looked everywhere in the description and I couldn't find the link to that transmission website. It's really sh1ty when you use somebody's footage and don't make it easy to find their site.
This is a great show of how an F1 gearbox from 25 years ago worked.
It's still super-sad that the WHOLE USA tends to (mostly) ignore F1 ... new rules for new strategy and super fascinating engineering; stuff WE love, but (again) not pushed in the USA.
Do F1 rules mandate an 8-speed gearbox? It seems like you could save a decent amount of size and weight by removing a couple gears and spreading out the ratios, with modern turbo-hybrid powertrains having such a wide power band. I just don't know how much freedom F1 teams have to experiment.
I'm always curious how engines cope with the sudden changes in RPM due to very fast gear shifts.
Gears, how quaint, it's about time F1 started to embrace the inevitable... I know I'm going to get flamed, but the future is electric, and that's from a petrolhead F1 fan since JH won in '76.
Outstanding video! Very informative and interesting, even to a 74 year old retired machinist. The precision work that goes into building one of these trannys is unbelievable. Would like to know for sure just how much computer-based processes goes into the machine work that is required to ensure that all the gears, bearings, spacers, dog rings, etc. do their job under what must be unbelievable stress and strain. Thanks again for the great vid.
As I've owned 34 motorcycles and worked on the internals for a lot of them, I had no prob understanding this vid. There is nothing really special about the operation and layout of an F1 gearbox then, just the precision and materials.
Quick, someone shows to this Pro-Sim so they can hook up with Quaife for a 55K simracing shifter.
So much wrong with this. The gap in the bell housing is for a HMA device
Was cast titanium not 3D printed!
Carbon panel in the bottom was FIA legality
Could write for hours on this gearbox
I would have expected a more sophisticated gearbox. Something more similar to an automatic gearbox with planetary gear sets.
My car has 9 gears and this only 7.
Doesn't make sense - but there must be an explanation.
Sure the tech and driver skill is cool, but wouldn't that kind of money be better spent on developing and building more affordable transportation for the masses? How about a 4 seat car that gets over 100 mpg or semi trucks that get much better mpg? When it comes right down to it, who really cares about how fast these cars can go around some track?
What a crazy way to edit a clip! No way you’re able to watch it to the end. You’re completely worn out after 3 minutes. F1 isn’t MTV, and certainly not when the aim is explanation!
What a pity …
