The incredible engineering and brain power that goes into these Toyota drive-lines is incredible isn't it? Just an amazing feat of engineering on their part.
It is, I just wish it was possible for Toyota to add exhaust based heating of the engine oil as a way to counter the insufficient heating which comes with such intermittent heat cycles as hybrids have. I have to wonder how much electricity that would take.
@@alexwalker8422 I suspect if it was feasible they would have done it knowing how crazy Toyota looks at efficiency everywhere. My brother (a Waterloo and MiT engineer with his PHD) worked for the Lexus plant here in Cambridge and said they are crazy at looking for things to always be more efficient but not at the cost of reliability. So I'd have to imagine that they considered multiple ways like that.
@@alexwalker8422it does already have it since multiple generations. On the downpipe, I think behind the catalytic converter, there is a heat exchanger which heats the coolant and due to the oil cooler (coolant to oil heat exchanger) the oil is heated up quickly as well.n This fact combined with the very good engine with great combustion results in very clear oil even after 30,000km Intervall.
Who says a man can't do two things at once? Here we have a Superman who can both dismantle an ECVT, explain what he's doing and keep an eye on his child. But maybe this man is a new kind of hybrid himself !
The power split device is so clever, so simple yet so complicated, so reliable and so awesome that it should receive the Nobel prize for engineering/physics or something similar. It truly is one of top 10 inventions ever created by mankind in any domain. Shout out to Toyota for creating this masterpiece and also to our guy who finds them, dismantles them and explains them like no other TH-camr does. I'm gonna buy a Toyota hybrid in a few years just for the power split device and the efficiency/reliability they come with, even though I'm a boxer engine fan and I like performance cars, a slowish Corolla hybrid with it's 60+ mpg is just too good to pass.
I own a 2016 Toyota Camry XLE Hybrid along with a 2013 Subaru Tribeca with the 3.6 Liter H6 engine (with a 5AT) and I couldn't be happier, especially with the 100% Synthetic Fluids used throughout both vehicles to have them operate at peak performance!
@@speedkar99 the next BRZ most likely will, but GR86 will have a Toyota engine. They will share most of the chassis, interior and tech, but will have different powertrains because Toyota doesn't want boxer fails. Or they could split up entirely and both will build something on their own.
it's not really 100% Toyota's invention (there's a patent from 1970's patents.google.com/patent/US3566717A/en) but hats off to Toyota for actually making it possible for practical, mass production use, making it reliable and doing further development.
They are *Way* better than people believe... I went from a BMW 530i to a JDM Toyota Aqua (aka PriusC) and my fuel bills dropped by 3/4 a *Year* and it gets an annual service and it's never ever missed a beat. Tires don't wear out they die of old age, lol, same as brake pads/drums.
2014 Prius C owner here with that same 3rd gen hybrid syn ecvt sys currently at 92k miles. It's a straight up bullet proof system when maintained properly.
I have 2013 Toyota Fielder Hybrid which is actually is Prius C, the same car technically. My real milage now is about 300000 km. This transmission only need is a 4l can full of ws transmission fluid every 60000km.
I always watch your videos. They are precise/ informative/ and better/ then most mechanic teachers I ever had ( airplanes). Well done sir and you find time to slip some humor into the mix too. Excellent, I now have a basic knowledge of how a Toyota hybrid electric motor works. Would hate to have to pay for any of those 'big parts'. Nobody describes the function of all your engines like you do. You have a gift sir.
Had to rewatch several times because it was confusing to hear the power is changing, but I think what you really meant is wheel speed in some cases. What it comes down to electronic control of torque, speeds, and electromagnetic resistances. Amazing transmission, thank you very much for the all the work you’ve done here, including the editing and the teardown itself. Awesome work
I currently have the newest toyota hybrid system and toyota have worked wonders, it is so smooth its hard to tell when the engine kicks in, you can now lock in ev mode on occasions up to 37 mph and I have managed about 3 to 4 miles on battery and when you consider how small the traction battery is and the weight of the car I have the corrola touring sports estate so it is about 1.5 tonnes, the fuel economy is amazing and the engine noise is much reduced unless you floor the accelerator when it can get loud but it is extremely rare you would do this as it has plenty of power, it's a shame everyone is being pushed towards full electric because these hybrids offer a much better solution and are much cheaper to purchase, western governments have bet on the wrong horse
It's the lobby groups which decide - not the governments. If Warren Buffett hasn't put so much money in BYD or Elon Musk propping up Trump's campaign with millions of dollars we wouldn't be having this conversation ...
OMG, another great explanation of how it works at the 12min point, And don't miss the comment about Prius drivers moving over to the left lane to slow the traffic down, especially while in the HOV !!!
I cant say enough how much i love your demonstrations and explanations!!! Replacing expensive workshops one video at a time! This mechanic thanks you 🙏
A beautiful piece of engineering, As much as Toyota can be conservative, it can also be innovative. I believe more in hybrid cars than in electric cars when it comes to the medium-term future of the car. For the long term, we don't know yet.
I have always been against cvt transmissions because of how unreliable they are but after seeing how this one works and there is no belt involved its changed my mind plus after driving a new camry with this set up its actually amazing how smooth and responsive it is when u put your foot down
The Power-split device is crazy smart, mechanically simple, and ultra reliable. No clutch, no friction, no wear. A couple of eletric motors, a planetary gear set, and you're done.
Awesome explanation! And that "whenever you decide to overtake and block that left lane" was a killer! I own a Toyota Corolla TS 1.8hsd. I initially went for a Skoda 1.5TSI+DSG. But that HSD system and the eCVT technology is so praised. I am fascinated by the performance as it delivers torque at lower rpms and the electric motor also serves as a turbo when needed. And can be economical when gently driven. Initially I thought they use the CVT belt and pulley but then realized eCVT is a different breed. And oh my the technological approach. Looks and works completely different compared to a manual gearbox (or DSG which runs the gear changes in VAG group vehicles). The engine is the old VVT simple and decent cc(size) from the 2ZR family. Will see the long term reliability.
It is essentially an automatic transmission, replacing the hydraulic brake clutch with electric motors. They can act like brakes/ rotate in one direction to charge(applying less braking force )/ rotate in another to accelerate the output.
I wold love to see a 3D printed version of this like there are Automatic and Manual gears. This is a simple and elegant masterpiece that for some reason doesn't get much attention
Before you explained how it worked, I was thinking that it was just the same as Nissan's e-Power since it seemed like the two motors were the only ones moving the output. Amazing how Toyota still managed to connect the engine directly to the output when needed.
Thank you for this amazing explanation. My hands are still clean despite learning something new. If I was to buy a hybrid it would be a Toyota, nothing else.
E-CVT actually gives me hope for CVT longevity. Working Nissan/Jatco I have had my share of warranty claims. Toyota would make a continuously variable transmission that’s durable. Toyota and Lexus win the engineering race again (IMHO)
What about the battery, does it need replacement after some years that cost nearly as much as traditional cvt? Maybe it will be better if they use LFP, but I see no japanese hybrid that use one, only chinese one
@@speedkar99do you have access to DM-i 5 hybrid transmission? Those seems to work differently. Fron what I understand, the engine either directly connected to output shaft or not. Basically it doesn't have the means to control the output ratio of the petrol engine.
I would say the Altima and the Rogue are the most common. Most owners never service the NS3 fluid and it burns everything up intentionally. I heard P17f1 (judder code) in my sleep. I don’t have the figures but if I had to take an educated guess id say 1 in 3 fail before 120,000 miles / 10 years.
Had an option to drive a '13 Prius and absolutely loved it. The car was so effortless and comfortable, even though some people say it's noisy; it isn't at all. It wasn't slow either. The big drawback on Toyota's Hybrid system, as well as everyone else's really, is that repair costs can be in outer space. Ordinary cars aren't that much better all around, but Hybrids have their own possible expenses. Buying a Hybrid can almost be equal to buying a BMW, Mercedes or Audi when big repairs come up, meaning that the savings in gas just blew out the window. With that being said, a Hybrid is still miles better than an all electric vehicle. On a [Toyota] Hybrid, the chances of repair are small, so the averages of still saving money are in your favor. To be fair, MANY cars today that break down are costing a fortune to fix, so singling out a Hybrid system isn't completely honest in comparison.
bought a 2012 Camry Hybrid and I cannot express how much more enjoyable driving is now, I've been driving manual transmissions my whole life (eastern European) and in the city it felt like a chore. I will never buy a different car in my life now, probably will replace it with a newer Camry model in the future
can you pls. make video sharing your thoughts between Honda vs Toyota hybrid system, pros and cons of their designs and which you think is more reliable? thank you!
@@speedkar99 I enjoy all your tear down videos and thoughts on how things are designed. I also like your car reviews bc you cover the mechanicals. Thank you!
+1 would like to see how the modern honda system differs. My gf has a CR-V hybrid and it's pretty solid from a driving perspective, not fun or anything, but a good utilitarian car
13:10 at least on my 2002 Prius, I can *hear* this happen. If the engine is idling and I start moving forward, it sounds like the engine starts lugging. Then the engine slowly spools up to match the demand for power. 15:50 I frequently EV at 35 in my '02. The official limit *is* 40. 62 for the gen 3.
An interesting dismantling presentation, and a good description of how it works towards the end. The other feature of the Toyota system is the way the engine itself is managed, to maximise it’s thermal efficiency, albeit at the expense of limiting the power output (which is overcome by the traction battery). In effect, it’s an emulation of the old Atkinson cycle, with shorter compression versus power stroke, most of the time, plus a lot of constant speed for an engine that never idles. Incidentally, on my 2022 T Yaris, it’s possible to run at much higher speeds than 40 without the engine, in the short term until the battery runs down to a certain percentage.
Really cool stuff, but you have torque and power mixed up here and there. It doesn’t really matter for the explanation here, but the torque split over the planetary gearset is always the same. It is basically like an open diff. Power split can be varied because the rotational speed varies.
I worked on coding with resolvers at a previous job. Specifically, they have an input phase and two output phases. The computer knows the absolute position of the resolver based on the amplitude of the output phases. But uh yeah, you can figure out the speed based on position over time... an interesting tidbit is that this is a "variable reluctance" resolver. I don't really know what that means other than there's efficient parts to do the same job that the old resolvers did. I think these only came out in like 2008...
Because CVT stands for constantly variable transmission, and this transmission is constantly variable. It doesn’t designate how the transmission is constructed. I personally think that Toyota/Lexus have made a mistake calling it this, because I’m amazed how many reviewers still describe the transmission as having belts and pulleys.
@@senseofthecommonman Absolutely correct. Even i was reluctant to buy a toyota ecvt because it had cvt, because i did not know better. Now i genuinely think it is the best part of the whole car.
Just imagine how much better these would be, and how much longer they would last if they were built the way the engineers originally designed them. Before the bean counters cheapened everything for maximum profit. As long as they can charge a lot and they last until the end of the warranty. Nothing else matters
You don't need a core to induce a magnetic field, just a loop of wire, it just shapes it and something with eddy currents, that's probably the lamination's contribution.
The Toyota and Honda e-cvt are the only Good cvts out there in terms of reliability and last much longer than just about anything out there with examples having done 700-800K miles with only simple fluid changes.
EV fanboys lambast Toyota's resistance to make a full EV, but even 30+ years later the dual motor planetary gearset hybrid is still a marvel of engineering and mixing the best of both gas + electric drivetrains.
G day Speed kar from Waterloo ont I am gad u get along well with ur family Interesting video It got me more confused , will have to study more. Ths good video. Ur little one will learn alot
SHREWD,Speedkar99 Tutorial outstanding Can't wait for the next training video,Speedkar99 Take care,Sir From Nick Ayivor from London England UK 🇬🇧 ⏰️ 22:31pm Good Evening
Does the Toyota Hybrid Synergy Drive (HSD) have traditional engine braking? So, even when its battery is full, the car still have its traditional engine braking. Honda hybrid e.HEV drive, once its battery is full via regenerative braking, the car will lose its regenerative braking.
Wow, been looking for a video like this! SO it looks like it's mostly (from what I can tell thus far with my limited understanding) the bearings are what could go first depending on your driving habits, I know i've seen that sort of thing with the Ford ECVT on the Fusions
hi, i assume since this doesnt have valve body, solenoid, torque converter, clutches .. maintanence of hybrid ecvt is much easier and will give long life then regular CVT. pls advise your opinion
if a prius engine and motor set is removed from the car is it possible to use it as a generator to power a house? and what if we put a electric motor in place of a normal transmission (in a normal ICE car) to work as a generator, run the engine at constant rpm, and then use a electric motor to spin the wheels?
The incredible engineering and brain power that goes into these Toyota drive-lines is incredible isn't it? Just an amazing feat of engineering on their part.

Great explanation of a complex system.
I'd say it's simple...compared to a typical automatic or CVT
Perfect mechanism, it also has the ability of redundancy (electric or fuel engine). Thanks for a clear demonstration video
Thanks. It's not completely redundant because the motors need to charge the battery and start the combustion engine.
Absolutely Absolutely awesome presentation and great transmission too. Smooth shifting and transition from ev to combustion.

One of the best explain video I have ever seen.
I worked on coding with resolvers at a previous job. Specifically, they have an input phase and two output phases. The computer knows the absolute position of the resolver based on the amplitude of the output phases.
But uh yeah, you can figure out the speed based on position over time...

Nice. The 2 output thing makes sense to determine direction.
Why it called a eCVT? I don’t see any CVT unit components such as belts or pulleys but this thing is much quicker & smoother than normal CVT
Because CVT stands for constantly variable transmission, and this transmission is constantly variable. It doesn’t designate how the transmission is constructed.
I personally think that Toyota/Lexus have made a mistake calling it this, because I’m amazed how many reviewers still describe the transmission as having belts and pulleys.
It's continuously variable in its output ratio by adjusting the speed of MG1. Doesn't need to have pulleys and belts to be a CVT.
@@senseofthecommonman Absolutely correct. Even i was reluctant to buy a toyota ecvt because it had cvt, because i did not know better. Now i genuinely think it is the best part of the whole car.

Nothing like a CVT, and that’s a good thing.
Toyota should have put that fluid level check on the u760e instead of the pain in the but straw thing. Thanks for the video.
The best explain ever see ❤
Well thank you
This is very cool technology and well presented.
This is world beating technology But still Millions of people around the world don't see Toyota as great cars
Best auto transmission
Agreed
i've heard the terms stator and rotor a million times before. it never occurred to me that it was related to stationary and rotation.😅
Fun fact: "Volvo" is the Swedish word for "rotating".
This setup just works
Agreed! And it's reliable which is what matters
Awesome explanation!!! Thanks
Just imagine how much better these would be, and how much longer they would last if they were built the way the engineers originally designed them. Before the bean counters cheapened everything for maximum profit. As long as they can charge a lot and they last until the end of the warranty. Nothing else matters
Engineers now design the failure points into consumer products. It saves OEMs money on engineering. 💰
Это самая надёжная трансмиссия, только меняй жидкость и езди.
So all toyota hybrids have an e cvt including my 2019 1.8 hybrid toyota chr?
Yes. Toyota models with fuel saving hybrid systems use eCVT for quite some time now. CHR is one of those models.
@venelinkeremedchiev9643 thank you very much!
Yeah
You don't need a core to induce a magnetic field, just a loop of wire, it just shapes it and something with eddy currents, that's probably the lamination's contribution.
Best explanation.
Thanks!
The Toyota and Honda e-cvt are the only Good cvts out there in terms of reliability and last much longer than just about anything out there with examples having done 700-800K miles with only simple fluid changes.
The Honda 😬
Chevrolet Volt is quite smart with 3 clutches th-cam.com/video/o3-wGOyT2-I/w-d-xo.html
Fantastic
EV fanboys lambast Toyota's resistance to make a full EV, but even 30+ years later the dual motor planetary gearset hybrid is still a marvel of engineering and mixing the best of both gas + electric drivetrains.
I wonder how much power those electric motors make? I really want to make something out of them!
Same. Seems like you could make a badass cargo trike with just the eCVT and no dino engine...
30kw more than 500V
G day Speed kar from Waterloo ont I am gad u get along well with ur family Interesting video It got me more
confused , will have to study more.
Ths good video. Ur little one will learn alot
great video. P610 transaxle?
SHREWD,Speedkar99
Tutorial outstanding
Can't wait for the next training video,Speedkar99
Take care,Sir

More to come! Thanks
Does the Toyota Hybrid Synergy Drive (HSD) have traditional engine braking? So, even when its battery is full, the car still have its traditional engine braking.
Honda hybrid e.HEV drive, once its battery is full via regenerative braking, the car will lose its regenerative braking.
Yes
I’ll tell you how fast the brakes wear down when I do a brake job on my Prius, 150,000 miles and still on factory brakes.
They'll probably rot before they wear down
Wow, been looking for a video like this! SO it looks like it's mostly (from what I can tell thus far with my limited understanding) the bearings are what could go first depending on your driving habits, I know i've seen that sort of thing with the Ford ECVT on the Fusions
you should try a full car teardown thatd be cool
I have done a full teardown on a series of videos back in 2017-2019 for a Infiniti G35 and Toyota Corolla.
Does it have a fluid innit? If yes, how often the fluid on these eCVTs need to be changed?
Yes it does. Since it doesn't use the fluid to activate clutches it may last longer than a traditional automatic.
Yes it does. Since it doesn't use the fluid to activate clutches it may last longer than a traditional automatic.
مبدع. وغني بالمعرفة
Thanks
Superb video. Thank you.
You're welcome!
hi, i assume since this doesnt have valve body, solenoid, torque converter, clutches .. maintanence of hybrid ecvt is much easier and will give long life then regular CVT. pls advise your opinion
Finally!🎉 not sure why the Subaru is floating around tho
Nice
Impressive.
Some day I hope you will show Hondas eCVT (i-MMD).
Thanks. I'd love to. I've already investigated their IMA system.
@@speedkar99 Thank you, I will have to check that out next. 😃
Love your videos.
Wow! How the hell did they come up witht this?
But it is extremely complex compared to a regular EV.
How? It adds 1 motor and a planetary gearset.
It's way simpler compared to a hybrid with an aditional gearbox
Agreed. And that's what makes it reliable. Except ford fusion did the same and made it unreliable somehow. Video to come soon!
Correct me if Im wrong, but isnt the Ford Fusion Energi the same? Ford and Toyota worked together to engineer this system, correct?
if a prius engine and motor set is removed from the car is it possible to use it as a generator to power a house?
and what if we put a electric motor in place of a normal transmission (in a normal ICE car) to work as a generator, run the engine at constant rpm, and then use a electric motor to spin the wheels?
A Great Video!!!
Thanks!
