Or we can just kidnap/clone him and force the clones to teach at universities. It's for the better of humanity, victories eventually come at a small price.
I know this was more of a rhetorical question, but the gist of it is that your university professor doesn't really have to go above and beyond. He only needs to do his job, and if he isn't passionate, that's that. Jason on the other hand needs to be good at what he does, since his success in teaching is directly proportionate to how well his channel is doing, and thus his income.
The thing is your professors (need to) explain things more indepht, include more math etc. Obviously it's harder to understand if it's more complex. These videos explain the basic principle in good detail, but that's it.
Todestuete yup exactly I agree. A lot of people miss/forget that. He explains the basic concept. But it will always be harder when we have to go into the math and go more in depth.
That's quite the elaborate pun to get to the magazine! Koenigsegg: Design a supercar that requires no transmission, only a torque converter to shame other hypercar manufacturers Also Koenigsegg: Doubles down on the engineering and reinvents the transmission to again shame the competition.
NoFanSLand. It’s amazing the amount of groundbreaking stuff they come up with at Koenigsegg. The major car companies probably have multi billion dollar development budgets and can’t even compete with a niche car maker for ingenuity!
@@David-lr2vi can't compete with Koenigsegg? To be fair, all these "innovations" Koenigsegg came up with (Free Valve, Lightspeed transmission, top mounted spoiler, etc) are pretty meaningless if the car is not performing. For example every McLaren Senna with half the power or even a 488 pista is faster around tracks than these Koenigseggs. Koenigsegg cars are brutal but way less refined, they often lack traction or stability, which makes them hard and not fun to drive unlike cars such as the Gt2rs, the pista or the Senna, which all are way less powerful but better performing.
Nik7 BKH. Well McLaren is another niche car maker. I understand that the whole package makes the car. My whole point is that it seems that it’s the small volume car makers that seem to be doing all the R&D these days and not the mainstream companies like Toyota, Honda, Ford, GM, etc. Maybe the big car companies are all spending their R&D money on electric cars?
Ha, fun to think about. You could actually figure it out by trying the different gear pairs, and seeing which individual clutch didn't work based on the three forward speeds that rely on it.
@@dank7491 he didnt he understood the joke as he said "Ha funny to think about" than explained how the problem can be solved also you wrote too many O's Baka
9:28 "So you're on the highway cruising, you want as much power as possible" Yeah, to undertake that truck hogging the left lane @ 55 mph, being in a 1600 hp Koenigsegg I would need just that
Coffee Pjesht nah, it’s so that when you see someone come flying up on you in a car they think is fast and you want to show them what fast really means. Or, when you want to pass that person who is causing your lane to go significantly slower than the passing lane so you can catch that opening.
Granted Koenigsegg are always playing around with technology that might be implemented in normal cars. They've been working on their freevalve technology for a few years now which (like the transmission) make the engine smaller and more efficient. This transmission could easily be implemented in other cars.
When the light switches from green to yellow! It's a shame they focused too much on how to make a 7 clutch car instead of adding another 400hp, make it an even 2000hp with maybe just 5 clutch?. For this reason I'll stick with my Prius.
As far as I remember it was just the opposite. Engineer: 7 clutches Christian: you mean 7 gears. Engineer: no, I had my meds, 7 clutches and it works. Christian: you are right, it works /someone please check his meds box before I give it a green light/ Engineer: What are you looking at on my desk? Yes my pc is unplugged but the ZPM works just fine... Check out this gearbox, this one is cool! :-)
“Well sir, we’re having a special today. For every three clutches you replace, we’ll throw in the fourth for free. That’s 8 clutches for the price of 6!”
@@theenzoferrari458 well you see if you're in 9th gear and you want to go to 2nd gear, 9+2 is 13, which is 2 digits and a car can't handle that much digits. in the game, the number overflows and loops back around to 1st gear, so its fine.
Beastly Buick V6 It’s actually ignorant to not buy it. The people who have the chance to buy it can resell it and make crazy amounts of profit. This type of car resells for 2 to 3 the original purchase price.
Im studying mechanical engineering at DTU in Denmark, one of our teachers helped koenigsegg building this transmission. He told us that the biggest challange with this transmission was that the gears had to be very thin because of all the clutches. Most computer programs said the transmission was completly impossible to design. The tolerances in this transmission is extremely tight, and also the expected lifetime is not that high :D
He propably lied cuz Koenigsegg haven't said anything about it being bad in durability. The latest video about the gearbox litterly says it has very low wear of the gears and clutches.
Either way it’s a revolutionary feat in engineering and it’s too bad this was developed in the tail end of ICE era of automotive technology (although I don’t fully believe ICE is as close to being phased out as everyone wants us to believe, it is inevitable) I truly hope koenigsegg will license this to other manufacturers so us as simpletons will get to experience this. This has long been dream by car manufacturers and enthusiasts alike. Bravo, damn swedens put a perpetual watch in a transmission
I'm in, too. But be warned. If everybody of your 2.2M subscribers gets 5 Minutes of driving time, the car needs to operate non-stop for 21 years. Better get a dedicated pit crew, a dependable fuel supplier and a ton of tyres.Edit: But you might get a couple of world records: Highest number of people crowdfunding one car. Highest number of people driving one car. Reaching 1 Million kilometers/miles in the shortest possible time with a single car. And many more :-)
@@ValentineC137 NEVS and Koenigsegg created a joint venture on 29th January: "partnering up to develop a product for new and untapped segments, leveraging both of the companies’ strengths." This might mean a fully electric Koenigsegg. :D
It's a mystery that a very low production car company can actually innovate in such an expensive R&D high tech area like this. Most "bespoke" manufacturers have no choice but to just use other people's parts. Even Rolls-Royce used GM transmissions. Amazing.
The difference being is that cars like Rolls-Royce are going to driven unlike the Koenigsegg which are garage queen due to how long it takes to get any repaired when the cars break down which happens frequently. Most of the technology koenigsegg uses has already been experimented by other automakers. There’s a reason they didn’t use said technology mostly because the difficulty of mass production, too little improvement over existing designs, or being unreliable.
@@vablo7198 Actually, with fewer engineers, you can concentrate on the important design features. With a 100 engineers, you get too many opinions and a mediocre all-round design (does not excel at any one thing).
@@R4M_Tommy you're right about not having the Free valve in a production car. But we had protype engines running on the same concept in the 90s at Navistar. Unfortunately controllers weren't fast enough at the time to do it reliably for hundreds of thousands of miles.
@@abes3925that is all BS lies from u. Koenigsegg's has never broke down without an driver error being the reason like reving the car as soon as u start it. Koenigsegg uses billet aluminium blocks litterly more durable than the W16 from Bugatti.
Remember some years ago there were a lot of people saying that Koenigsegg made cars with highly tuned and modified engines and not much more than that... Well it's been time I don't hear (read) those type of comments anymore. Koenigsegg proves itself more and more everytime.
This kind of reminded me of bicycle gears. You have something like three chainrings on the front sprocket, and something like six cogs on the rear. A combination between which chainring and cog you are using decides the speed of your bike.
How does Koenigsegg handle the 3/4 and 6/7 shifts, especially with clutch overlap for continuous power delivery? Those two involve swapping not one but two pairs of clutches - shifting one sub-transmission a step up and shifting the other down. All modern multi-clutch automatics involve only a single clutch-to-clutch swap for every sequential and double shift to avoid engine flare or bogging down the engine.
Combining both the best stuff about single clutch and dual clutch, having 9 gears, shifting incredibly fast, all while being incredibly light. Christian and his team are a bunch of geniuses. And also major props to you. Beautifully explained. You and PapadakisRacing are the only RU-vid channels I watch every video from.
Watch Geek it does feel surprising at first but if it’s anything like the IT industry it’s the very reason(being small) they have such fast innovation cycles. Of course the prerequisite for that to work is that they really know what they are doing. And they do.
Wow, this was pretty informative. I was wondering if you could do a video on specifics on the clutch packs on the Jesko (clutch packs on modern transmissions period, actually)? I know it uses solenoids and all, I think it would be a cool video if you were to dig deeper in the differences and benefits/drawbacks to this component.
You only need to close two on the same shaft... And I bet this thing is gonna blow up often... all it takes is one clutch to fail and locka and it's over... (although, clutches usually slip with they fail, so maybe it's not such a problem).
@@mikkihintikka7273 in dual clutch transmissions they are pressure _closed_ (unlike on a manual, where the clutch is pressure _opened_ ), it's a safety feature. I guess it's the same with the königsegg. For park you only need one actuator and a notch in the output shaft.
@@mikkihintikka7273 yes, like on a motorcycle or manual trans car traditionally; but with so many clutches in this design(7 counting reverse) where most of them have to be open(5 open and only 2 closed for forward gears, and 6 open for reverse) it would seem better if normally they were all open in a 'resting' state ... a car or motorcycle uses springs to hold the clutch closed at rest, but here you could just use a solenoid to close it at will? - I wish he would have said how they operated the clutches in the video
@@tcroft2165 Now use the C7 ZR1 for example. Has Out lapped the 720s on track like V.I.R While also running low 10second 1/4 Mile times and also weighs 3600 ibs
Plum_Crazy 1992 What exactly is over engineered on the LST? It’s small, simple, weights 90kg (200lbs), doesn’t even need a flywheel and can handle 1600HP.
Thanks for a brilliant video! Koenigsegg is leaps and bounds ahead of everyone with their incredible engineering, and you did a great job of explaining how the LST functions.
Not that i am some enlightened being or anything like it but what most people don't realize is that when you pay millions for a Koenigsegg you are not paying for a car, you are paying for a Van Gogh on wheels, whereas instead of a painting, you get a machine engineered to art.
Lluis Fargas López yes I’m aware that’s the bulk of it but I’ve already taken intro to design and engineering foundations and gear ratios, torque, and mechanical adv are all big topics
@@mohamedhussein5190 i see you are an enthusiast. You will get some fun fore sure if you don't worry to much about marks and try to enrolle in sone extra curricular activities. Right now I'm into the design of the refrigeration system for the batteries of an electric competition motorbike. Thought what I've liked the most are structures I have started to find some fun in the thermodynamics world and simulations with cae programs.
Exactly what I was thinking.... I respect Christian von Koenigsegg for his willingness to think outside the box. He brings something new with every new model
I'm constantly amazed how Koenigsegg manage to come up with such amazing engineering all the time, such a small company but their tech is ahead of the big boys like Ferrari
As an automotive engineering student this is just baffling. Koenigsegg revolutionizes so many things in automotive technology which has been somewhat the same for a hundred years..
as an automotive engineering student.. you should know this is simply a traditional automatic gearbox with cog gears instead of planetary. im actually worried about the future of automotive engineering if you think this is baffling or revolutionary. pop quiz: explain how this gearbox operates fundamentally differently than the automatic in a '69 chev? you cant. its just a few extra gears, and the gears are shaped differently
It's like gears in a mountain bike 🚲 But true: some of these clutches (if not all) have to deal with enormous torqe. All of them must be actuated in some way (oil pressure?)
great job as always, yoru videos always make it very easy to understand. Your diagram is so good that you didn't even need more of the video because as soon as I saw the diagram, in less than a minute I understood how it worked
Yea, it would be nice to know what's actually happening to these technologies. With Koenigsegg's advancements, like the removal of camshaft and this smaller transmission, we could be expecting as much as 1/4 ton of weight reduction. It would be a real shame not to see that permeate the whole market.
Paul Bautista yeah I hope to hear more updates from them soon. They claim to have put their actuators through hundreds of millions of cycles of testing with no measurable wear. Pretty impressive.
I knew there was a reason I wanted that issue of road and track! I lost it at the first airport, flew to my destination and bought another copy at that airport. Yet again I lost the magazine. When I returned to my home airport I bought it again and brought it home. I didn't see that article was written by you!
So, it's like a basic automatic transmission, where any gear can be in theory selected after any other gear. Expect, when clutch is fully engaged, it's a direct connection, but with AT it's almost always a hydraulic connection. Or am I wrong?
Almost, except all modern automatic are based on planetary gearsets, and the powerflow and clutch schedule are cleverly arranged such that all sequential and double shifts are accomplished by opening one clutch pack and closing another. The Koenigsegg LST requires swapping two pairs of clutches on the 3/4 and 6/7 shifts, which makes the shift a lot more complicated to control properly to avoid engine flare or bogging down the engine. Also, modern automatics bypass the hydraulic torque converter fairly early on in the gear ranges with a torque converter clutch.
If anyone remember that in a gear cycle where we have 21 gears, that cycle uses the same principle of gear changing. So Koenigsegg just used that principle from cycle & make everyone surprise.
@@gertahnstrom784 First they build a car without a gearbox and just a huge torque converter, and now they build a car with a (kind of/possibly) automatic transmission without a torque converter. Can they please make up their minds? 😋
Yeah, so much talk about what just about any AT has. Are the only differences here that it's not planetary and has more clutch packs? Both being not that unique actually.
Oh finally.. I always had problems with clutch .. finally one car with many clutches for a lifetime . Definitely buying .. finally someone heard my prayers.
I’ve always wondered even as a younger kid if it would be possible to do this very thing with fixed gears... this is so cool, not having neutral between just instant shifts with no delay
dude thats cool. ive been reading road and track for 25+ years. im 35. that's a great milestone to hit! dont know if it pays well but your at least famous enough to be resourced by major recognizable company's!! good job dude
How do they even manage to develop these amazing technologies while they sell so few cars. Granted, the cars are expensive, but R&D is also incredibly expensive.
Christian doesn't just manufacture and sell cars. Apparently they also own several sister companies that hold several patents and do other stuff related to automotive technologies. For example, the FreeValve. And if I am not mistaken, the recent Top Gear videos also mentioned about them owning their own carbon fibre factory in Spain. Pretty sure they also invested in several other companies.
If you look closer, Christians solutions are at most time simple and straight forward to implement, like this gearbox is just a manual gearbox with clutches for every gear while other manufacturers spend billions on cutting corners and developing tech that guarantee a fixed point of failure
@@dubeights even the camless will have a limit. its still moving mechanical parts that can only take so much force before parts begin to stretch or fail.
My suggestion would be to check out TougeTime's MR2 Spyder autocross videos. He had an S2000 first but got better time on his 2ZZ MR2. You can do a 2ZZ swap video, and talk about the mid-engine balance, the air ducting for the read engine, reroute custom exhaust to make room for a trunk, discuss and the oil leak -> precat disintegration -> lift vacuum -> 1ZZ problem, you can talk about why toyota went with macphersons, and so much more!
Road & Track article...that IS super cool. Btw, you are awesome to listen to and learn from. Teachers need to be engaging to help people learn, you do a great job. Just my opinion.
Great explanation as always Jason! It's really fascinating they put clutches where syncromeshes are usually at. From what I see the clutch 4, 5, 6 are the busiest ones for daily city driving as they're responsible for 1st to 3rd gear changes. The least used one perhaps the clutch 3, if you don't shift beyond 6th gear you'd never use it. All this changes if you mainly run the car on circuit though. After a year of daily usage the clutch sets 4 - 6 would wear out the most, then perhaps the clutch 1? As there is no "flywheel" vs main clutch plate slip to start the car, like in standard car, would this gearbox let the clutch 1 fully grip then let the clutch 4 slip to start the vehicle? Or vise versa? Or both clutches slip to start the car? In a metaphor for bicycle, the 1st tier gear sets are like you have 3 gears on front derailer and 2nd sets are the rear 3 gears - hence gives you 9 possible different ratio combinations. 3 is a nice number, 2x2 wouldn't really work coz that only gives you 4 speeds, 4x4 is bit too excessive (16 speeds) but might work for trucks.
I highly recommend the 370Z. I've daily driven one for a year now and love it. It's very confidence inspiring, easy to control, and surprisingly practical. That ~5.9cu.ft. of cargo has more area in it than some hatchbacks. I could go on, but of course buy what feels best to you at its best. Please don't decide until you've tried the Z on a windy incline and (responsibly) tried out that magic button left of the steering wheel.
Totally get it, simple!!! The 3 gears basically have 3 ranges or different ratios they can apply forces to, instead of all the movement of traditional style gear, they all stay mated, rotating at their own speeds but not applying force to the output shaft until the clutch packs for the selected gear are engaged. The gears are ALWAYS ready.. When movement is reduced, so is time!!!
The greatest benefit on this system is, you can switch up and down and overjump some gears like a converter Gearbox. But the newest converter gearboxes are doing this right now also very fast.
Good call. If I had the parking space I'd own one of those; can't imagine them being any cheaper than they are now (which is already ridiculously low for what you get, unless you go for a competition pack model).
The key question is how long will the clutches last. In this design these clutches are holding the full torque of the engine while engaging and there is no main clutch or torque converter to slip, particularly during starting or slow crawling. Also, since the clutch packs are between the gears, you can't make them too big either. I think that a design like this for a street car would have a very short lifespan. Good thing that nobody is actually going to be putting miles on these cars given their cost.
Its not that hard to imagine. you just need to have the engine RPM to be the same as it would be after you would shift normally. Say you're in 3rd gear at 30mph you would probably be at 3000 RPM engine speed. When you shift to 4th it would go down to 2000rpm so if you pull the stick into neutral which requires 0 effort. Get the RPM to 2000 then put it in 4th. The synchros in the transmission essentially do that for you, but they can wear out. Although messing up clutchless shifting will wear out the teeth of the transmission
ive been picturing a supercar transmission similar to this for ages im surprised it took this long, the idea to have clutches for each gear is pretty genious tho
