Ecvt transmissions are good and ideal for city driving but as I recently found out driving my wife's Honda Crv hybrid touring sport to Las Vegas from Los Angeles....climbing up the pass was extremely difficult. Felt like I was driving a 3 cylinder car while pulling a space shuttle.
The Honda eCVT is a technological marvel. But there are lot of things Honda, a Japanese company should have looked at. The setup of Honda eCVT is complex and more costlier to manufacture and it still bears Clutches which inturn is vulnerable to wear and tear makes two points down on reliability. I still think Toyota eCVT is much better is terms of performance and reliability.
There's potential wear and tear in all mechanical components. The clutch in Honda's eCVT is not used to switch between gears as in a traditional gearbox. It's only used to couple the ICE to the transmission at higher speeds, so if you mostly drive in the city, you will rarely engage it. At city speeds, the electric motor does all the heavy lifting while the ICE charges the battery directly. This Honda system translates to better performance than Toyota's. I test drove both the CR-V and the RAV4, and the Honda was much more responsive on the throttle at both city and highway speeds. As to reliability, Toyota will have the edge because all of their best selling models are manufactured in Japan. That means cars manufactured elsewhere, including America and Canada, can never match the quality from Japan. These people have specialized in Quality centuries before the British Empire. I also see that you are a Toyota fanboy, and your Western mind tends to frame things in black and white. Just because you think Toyotas are amazing, that doesn't make its competitors trash. In the automotive world, and by Toyota itself, Honda is considered an equal in engineering capability.
@@tabularasa9554. The Honda is even more of an EV than the Toyota. That probably explains why you consider the throttle pedal response better (I haven't driven the Honda hybrid so I will take your word). But the Toyota is considered superior for fuel economy. Which is what many shoppers value. My only concern with Honda is that their engines sometimes get GDI without port injection. This runs the risk of intake valve contamination. Just more to worry about. And there is nothing CVT about the Honda approach. I wish they would just call it Series Hybrid with gasoline direct drive mode.
This tends to prove that the best and most innovative designs come from manufacturers who also work on aerospace projects. In the case of Japanese companies they have a better chance than others of having a dealership infrastructure capable of staying on top of maintenance and repair issues. If I ever had any cash I would buy Japanese, but sadly these innovations come at the end of my driving lifetime, having made much pollution over 3 million miles of driving. Better late than never.
It's taking the automotive over 50 years to implement diesel locomotive technology. A combustion engine couple to a generator to drive electric traction motors.
Diesel-electric locomotives use a serial hybrid drive train in order to (A) distribute motive power over many wheels and (B) provide high torque from zero rpm. What's missing? (C) Use fuel more efficiently. To do that, the engine has to restrict its power output - NOT RPM - to where it is achieved most efficiently. And that requires (D) a battery to buffer power and (E) modern computer control. Diesel-electric locomotives bear about as much resemblance to a modern HEV, as a hot-plate bears to a programmable microwave oven.
Railroads are studying battery electric locomotives. To operate battery electric trains? NO. They plan on adding them to a diesel consist to create a Prius like hybrid. The electricity made from slowing the train has always been wasted in the past (no big battery). The battery electric locomotive will provide the battery (and some extra tractive effort if needed) to store this energy. When the energy is used it will reduce diesel fuel consumption.
This system is much more than that. It has full ev mode, hybrid mode where engine power a generator and engine mode where engine is mechanically connected to the wheels.
It’s a good description. It does not really have a “continuously variable transmission” mechanically between the engine and the differential though, compared with the Toyota/Aisin eCVT, which does have one, via a planetary gearset. In simple terms, they have used a clutch compared with planetary gears. Thus they have used a term that does not correctly describe the electric/mechanical transmission. Not against Honda, as it was when it had a factory near to my place, and the best one I had from them was actually a Civic with a 1.6l diesel, which really was quite efficient and clocked up 4.4 l/100 km diesel fuel. After that I switched to Toyota hybrids.
I have the Honda CRV Hybrid Sport 2023. I understand there are 2 clutches in the transmission. One is for low speed which when engaged will allow the engine to combine with the electric motor to drive the vehicle which allows for times when urban speeds require more RPM. The other is a high speed clutch which engages at 62 MPH resulting in overdrive gear allowing for the gas engine to do all work. That is at best how I understand it and not sure I am correct. Would sure like to see someone tear a Honda CRV Hybrid eCVT apart to show how it works like Weber did for the Accord single clutch transmission mentioned in this video. It would help me know how best to drive my Honda CRV.
I am a fan of Honda's e-CVT but I've eventually bought a Clio E-tech. I don't know yet about the reliability but the technology is perhaps better as it combines the HP of the electric and the ICE engine and it drives better on highway at higher speed.
My son needed a new car. He bought a 2022 Volkswagen Jetta. 30,000 miles later the cylinder head gasket needed replaceing. So he bought a Mazda. Asked why he didnt buy a new Honda, he said they're putting CVTs in them, and they were having problems with them. For my Son to say that, i believe him. He does his homework. Unfortunately, the engine in his Volkswagen was a new design, so there was nothing about it to research.
On my 2024 CRV, I have been in EV mode up to speeds of 79mph. This video and the clips of the professor breaking down the ecvt is for the previous gen model, which is almost the same, but not quite.
This is not unique to Honda. Toyota did the same in their l610, l710 and i810 ecvts. Yet, Toyota managed to get much improved milage figures. Look at the RAV4 prime for example.
If you think a hybrid gains no advantage on the highway, you do not understand how hybrids work. Most likely, you think that the only benefit is from regen braking. While this video copies everything from other sites, and does get some wrong, it does show why it gains on the highway. For example, the part at about 5:20 was stolen from th-cam.com/video/6glpZTRT6qE/w-d-xo.html .
Hybrids usually use efficiency tuned Atkinson cycle gasoline engines. More efficient than the standard Otto cycle engine. But this kills the low end torque (which the electric motor has gobs of). Anytime you are burning gasoline the Atkinson engine is more efficient
I have an e-cvt Honda and I would agree driving at a constant 70mph is not as efficient as city driving, however I still get just over 60mpg on a long highway run. So I could not agree with you that for highway driving the Honda hybrid has no advantages. It certainly does and even on the Highway, it will still seamlessly switch to full EV mode when it can.
@@philiprobinson2011 . Incredible fuel economy. My 2013 Prius gave me over 58 on one trip but I had to hold back to 65 mph max. 52 is much more typical.
Where did you get these fuel economy number 😮. In Canada, Honda CRV Hybrid provides 7.4 L fuel consumption per 100 kilometers distance, not as you are claiming 4.5L. It may only theoretically possible with the most efficient condition (continously drive in 60 kilometers per hour speed on a straight flat road for 100 kilometers distance) without any passenger or loads.
Honda forums list a wide range in terms of fuel economy. I myself am getting around 34mpg, but I live in very hilly terrain and drive like Speed Racer in Sport Mode. Other users who live on flatter land report anywhere from 43-52 mpg. I tried driving very conservatively once and averaged around 42 mpg. But I couldn't stand it for long.
@@tabularasa9554there are news about Honda rigging the fe. I believe its true and even Toyota does it. Toyota states 20km/ L for their recent vios. I am still under 15 km/L after 1 year
@@repunzelification In my experience with the new Honda Jazz, Honda seem to underestimate the fuel consumption figures. Long motorway driving at 70 mph, I get 60 to 61mpg, around town the figure rises to 65 to 70. Official Honda figures are around 59mpg.
CVT Continuously Variable Transmission. There is NOTHING CVT about this setup. It is usually a series hybrid with a big electric motor (more powerful than the gasoline engine) powering the vehicle like the electric car that it is (most of the time). And the gasoline engine running as needed driving the generator. Out at highway speeds it would be inefficient to make electricity to immediately use it in the big motor so for steady state cruising the engine clutches in to propell the car. This is a fixed ratio 1 speed drive, nothing CVT about it. If you floor it to accelerate the gasoline engine will unclutch and go back to generating electricity while the big electric motor accelerates the car. Nothing CVT about it.
Car manufacturers have looked a bit at how they do in the tractor industry. No chains are used, but a hydraulic motor to create the gearing. Because chains on cvt are unsustainable when there is a lot of torque behind John Deere has made an IVT transmission with 4 gears and 2 electric motors. You can call the Honda transmission (infinitely variable transmission) (IVT) th-cam.com/video/aMzgT_FahBU/w-d-xo.html&ab_channel=JohnDeereUKIE
@@fivish . Yes. For steady state cruising. As I mentioned earlier if you floor it the gasoline engine will unclutch and return to generator duty (I'm guessing at a high rpm for maximum output) while the more powerful electric machine accelerates the vehicle. Very different from the Toyota Synergy Drive approach. Which avoids clutches.
The Honda eCVT is not a CVT its a hybrid. It has an engine which drives a generator which charges a battery which runs a traction motor. At motorway speed a clutch connects the engine directly to the final drive diff. Toyota do this so much better.
Just test drove a Civic hybrid and it's surprisingly fast; supposed to average 4.5-5.0L/100km. I think the CRV's added weight and all-wheel drive hurts its cause. There's a 335kg difference between the two.
i came here just to reconfirm, Honda e-cvt did not use stealt belt isnt? I bought Civic FE Hybrid 2023 but afraid with the Gearbox since lot of people say Honda CVT belt is sh*t. Can someone confirm this?
Not sure what a Civic FE Hybrid is. AFAIK, if it's a hybrid, then it's got the 'E-CVT', it's gonna be a E;Hev, so no belt system, it's the good kind. If it's NOT a hybrid (a 1.5 Turbo, I believe), then yes, it will be using a classic CVT with a first gear. If you have the car already, it should say E:Hev. If you haven't got the car already, you can ask the dealer or look at the order sheet.
Actually, the ECVT is not a gearbox, It just houses an Electric Motor, Electric generator, differential, and a Clutch to engage the Petrol engine at cruising speeds. It's like having a diesel/electric Locomotive, Instead here it's using Petrol. One petrol engine connected to an Electric generator gives power to the electric motor and charges up the Battery and an Electric motor which also drives the main wheels. So you have a Petrol engine with let's say 100bhp and an electric motor with another 100hp, Once you press the accelerator to move from a stop the electric motor drives the main wheels, and as soon the battery starts to drain the petrol engine kicks in to charge the battery, once you start to accelerate more to a cruising speed of let say 100km/h the petrol engine kicks In and this time it drive the main wheels by engagement of the clutch. this is how at least I understood the system, it's more called a Series Hybrid system, I may be wrong tough.
@@ripmax333 i think you're right, very simple but comprehensive explanation. But if i may ask, what is the downside of this kind of system, so that i can take preventative action.
That would suck having to replace that clutch. Eventually you will need to R&R it. I still think Toyotas Synergy Drive Hybrid with the planetary gear sets eCVT is still the best Hybrid system to date. On the Toyota you still have to replace the eCVT oil at regular intervals but that's a whole lot easier to do than a clutch replacement.
There are two clutches, one is a multiplate type running in oil, like a motorcycle clutch, whilst the other, as I understand it, is a single plate clutch only operated in emergencies to disengage the drive. So, as the single plate clutch operates so infrequently it should last for the life of the vehicle. The multiplate clutch also only operates infrequently as there are no gears, just the transition from electric drive to ICE drive at around 60mph, so should last far longer than any car with a conventional transmission where the clutch has to operate every time you change gear, or come to a halt.
An issue is that when it switches to engine drive on the motorway it is loud and feels like it's revving very high - very difficult to get used to and economy isn't that good.
In my experience this only happens when you accelerate hard, or when climbing a steep hill. Otherwise the engine remains very quiet and the change between electric and ICE is totally unnoticeable.
nops ...this one is more powerful and the regen is much smoother....this one is a 2 electric motor system..i drove the prius but this honda tech is way ahead....the prius is nice but this one much more smooth
Not the same. Mostly a series hybrid setup. Prius Mostly a parallel hybrid setup. It is unique. The Toyota is slightly better. Plus the Toyota engine gets port injection with the GDI. Avoiding the GDI only issues.
At 6:07 - The gas motor is running by itself above 62 mph, but its optimal RPM range is about 3700 to 4700 RPM?? That graph can't be right!! I would NEVER drive my car in that range! How long would your gas motor last if you only drive highway speeds??
Then the whole intension of having Hybrids will negate. Deisel engines are difficult to setup with electric motors which increase cost as well and increased emissions. So No to Deisel.
The speed threshold, when Engine Drive starts to be used, is NOT 100 kph ~= 60 mph. It's more like 65 kph ~= 40 mph. More specifically (and this for 2018-2023 Accords, but others are similar), in Engine Drive RPM ~= 37*MPH. So the limit is at about 1500 rpm. At that speed, and about 80 lf-ft of torque (about 23 HP), the green line enters the lightest blue region shown at 5:25. (The image was "borrowed" from th-cam.com/video/6glpZTRT6qE/w-d-xo.html ). Inside this region, it uses less than 210 grams of fuel for each kWh of energy produced. The absolute minimum is 208.1 g/kWh, at 2000 rpm, 88.5 lb-ft (about 34 HP), or about 54 mph.
They're two very different designs, both with their own set of advantages and disadvantages... Just because something says 'hybrid' on it, doesn't mean it's a Toyota.
Mechanically quite simple, just different than you are used to. Fewer parts than just about any other ICE car, and quite easy to troubleshoot. But it seldom needs that.
I really should read up on this before I have an opinion but when has that stopped me. I suspect the main advantage with this is is getting rid of a heavy gearbox in the case of a traditional box. or getting rid of what has tuned out to be a very problematic CVT's for a number of manufacturers. A good CVT is only reliable as long as it is driven strictly within its designed parameters. Using an engine to drive a generator to drive an electric motor is less efficient than using a geared transmission. The advantage is getting rid of the weight of the transmission, transmission loses due to friction etc, ability to recover energy in stop start traffic, and then theirs the torque of an electric motor. Plus the setup allows the IC engine to always be running in it's sweet spot. For slow stop start driving Engine>Generator>Electric drive probably works out okay. But nothing bets battery electric in that sort of driving. Motorways kill batteries. It's all about aerodynamics or monster batteries. So a direct drive IC engine works well, mainly because of the energy density of petrol. But it's only going to be as fuel efficient as the engineering and aerodynamics allow.
Toyota's system actually provides CVT action for the gasoline engine (nothing CVT about the Honda hybrid). The Toyota (and Ford, and Chevy Volt) uses a planetary gearset CVT. Very simple and reliable. At speeds below 45 mph the Toyota is an electric car with gasoline assist. At highway speeds the electric motors work to make the gasoline engine do most of the work.
Ecvt transmissions are good and ideal for city driving but as I recently found out driving my wife's Honda Crv hybrid touring sport to Las Vegas from Los Angeles....climbing up the pass was extremely difficult. Felt like I was driving a 3 cylinder car while pulling a space shuttle.
my insight is a rocket even when battery is low
The exact definition is series-hybrid with lock up clutch direct engine.
Correct. Nothing CVT about it.
Nissan have similar without the lock up clutch.

nops ...this one is more powerful and the regen is much smoother....this one is a 2 electric motor system..i drove the prius but this honda tech is way ahead....the prius is nice but this one much more smooth
Not the same. Mostly a series hybrid setup.
Prius Mostly a parallel hybrid setup.
It is unique. The Toyota is slightly better. Plus the Toyota engine gets port injection with the GDI. Avoiding the GDI only issues.
Why is this called a ecvt
It’s nothing like a cvt transmission
At 6:07 - The gas motor is running by itself above 62 mph, but its optimal RPM range is about 3700 to 4700 RPM?? That graph can't be right!! I would NEVER drive my car in that range! How long would your gas motor last if you only drive highway speeds??
The most optimal range from the graph looks to be about 1200rpm to 2900rpm.
What about reliability?
Infinitely more reliable than a conventional transmission or CVT
Toyota eCVT's have everything good this has but doesn't have the clutches that wear and break down.
I believe the Toyota's still have one clutch like the Honda, to separate the drive in emergencies.
Yes, bandu bandu bandu. Didn't understand jack
Hibrids should be dizel powered
Then the whole intension of having Hybrids will negate. Deisel engines are difficult to setup with electric motors which increase cost as well and increased emissions. So No to Deisel.
Diesels add weight and cost.
Hybrids add weight and cost.
Seldom used together.
👍👍👍
Like ffs honda just make the 10AT standard and have EV or Hybrid optional. This is unnecessary and prone to hurt reliability.
The speed threshold, when Engine Drive starts to be used, is NOT 100 kph ~= 60 mph. It's more like 65 kph ~= 40 mph.
More specifically (and this for 2018-2023 Accords, but others are similar), in Engine Drive RPM ~= 37*MPH. So the limit is at about 1500 rpm. At that speed, and about 80 lf-ft of torque (about 23 HP), the green line enters the lightest blue region shown at 5:25. (The image was "borrowed" from th-cam.com/video/6glpZTRT6qE/w-d-xo.html ). Inside this region, it uses less than 210 grams of fuel for each kWh of energy produced.
The absolute minimum is 208.1 g/kWh, at 2000 rpm, 88.5 lb-ft (about 34 HP), or about 54 mph.
Ai Ai Ai Ai ai😊

Sorry but it's a copy of toyota ecvt go look at rav4
That is Toyota design Honda coppied
Prove it.
They're two very different designs, both with their own set of advantages and disadvantages...
Just because something says 'hybrid' on it, doesn't mean it's a Toyota.
Extremely complex and too many parts, a nightmare for maintenance, almost impossible to troubleshoot
Mechanically quite simple, just different than you are used to. Fewer parts than just about any other ICE car, and quite easy to troubleshoot. But it seldom needs that.
Do you honestly think this has more parts than the 8 speed automatics you get these days? It's actually a massive simplification.
People like you simply project your fears on things you don’t understand.
@@jaapweel1dude acts like automatic transmissions don’t cost millions to develop and aren’t extremely intricate to construct.
It is clear to me that @pucheco69 doesn't have a clue how the eCVT works. It is a simple and elegant solution.
All is good until the warranty expires….. then say hello to Mr Moneypit.
Honda abandoned reliability about 20 years ago.
Liked the content but found it difficult to concentrate due the strange accent and timing of the narrator.
The voice it so in between of highest and lowest of many levels of annoying
Yetmore mass recalls.
Sounds wonderful and yet it does not give better fuel mileage than Toyota's hybrid synergy drive. Why?
I really should read up on this before I have an opinion but when has that stopped me. I suspect the main advantage with this is is getting rid of a heavy gearbox in the case of a traditional box. or getting rid of what has tuned out to be a very problematic CVT's for a number of manufacturers. A good CVT is only reliable as long as it is driven strictly within its designed parameters.
Using an engine to drive a generator to drive an electric motor is less efficient than using a geared transmission. The advantage is getting rid of the weight of the transmission, transmission loses due to friction etc, ability to recover energy in stop start traffic, and then theirs the torque of an electric motor. Plus the setup allows the IC engine to always be running in it's sweet spot. For slow stop start driving Engine>Generator>Electric drive probably works out okay. But nothing bets battery electric in that sort of driving.
Motorways kill batteries. It's all about aerodynamics or monster batteries. So a direct drive IC engine works well, mainly because of the energy density of petrol. But it's only going to be as fuel efficient as the engineering and aerodynamics allow.
You watch the video?
Because there is no transmission there are no worries about worn clutches or worn out gearboxes.
Toyota's system actually provides CVT action for the gasoline engine (nothing CVT about the Honda hybrid). The Toyota (and Ford, and Chevy Volt) uses a planetary gearset CVT. Very simple and reliable. At speeds below 45 mph the Toyota is an electric car with gasoline assist. At highway speeds the electric motors work to make the gasoline engine do most of the work.
Probably because they are both excellent hybrid systems.
