it sounds strange, need to listen again

I know the four shown, one half of a SBC.

sorry a CVT IS A PEICE OF ENGINEERING SHIT if it relies on variable diameter pulleys, its old tech from the 1920's, its makes no difference if it is fitted with rubber or metal belts, a manual transmission last longer than a CVT its life expectancy from new to fail is around sixty thousand KM, the ECVT would appear to be more reliable as it has deleted the use of metal belt & pulleys.

E CVT and Toroidal are the best

CVT (at least in Korea) was fitted to a Hyundai Stellar test car. These transmissions are older than you think.

I'm a Believer....I run the high RPM hell out of it, maintained each 30k.

Toyota hybrids are basically electric cars with gasoline assist. The main traction motor is direct drive to the drive axle same as most electric cars. Reverse is always electric. They just reverse the electric motor. The ring gear of the planetary gearset is connected to the main traction motor also. This is how the gasoline engine delivers assistance, up through the planetary gearset. When the gasoline engine is not turning but the car is moving the smaller motor is turning the sun gear such that the planet carrier (gasoline engine) is not turning (but the planets are spinning in place). When the gasoline engine is needed the smaller motor changes speed to spin up the gasoline engine and fuel and spark are applied around 1600 rpm. The gasoline engine never idles (a higher emissions mode). Out at highway speeds above 45 mph it could be argued that the vehicle is a gasoline vehicle with electric assist. The 2 electric motors do what it takes to make the gasoline engine do almost all of the work at the most efficient engine rpm. The speed of the sun gear motor sets the rpm of the gasoline engine. These transmissions are just planetary gearsets. Way more reliable than belt style (which uses friction).

Takes a person of higher intelligence to appreciate CVTs, low iq people can comment 👇🏼😂😂

CVTs in Toyota Hybrids are awesome.

CVT may be good enough for throw away light duty vehicles, but not for expensive or heavy duty vehicles. The fuel costs saved will go into a future complete CVT replacement. Metal to metal belt pulley friction without friction materials wears out metal hard parts. CVT just failure explode, nobody rebuilds them, you have to get an OEM replacement. Special.CVT fluid remains expensive and not a DYI replacement job. You might even have to reset the ECM.

Toyotas launch gear sounds good. But if it doesn't engage until complete stop it's garbage. The Dodge programing for its 8 speed doesn't go into first until standstill. So any rolling stop or even down to a creep at a stop light makes a sluggish start. Can be dangerous when your going less than 1 mph and try to pull across traffic and it's in 2nd. Frustrating because you can't tell why some times you have power that wants to spin wheels. Some times you have a hesitant dog.

Stepped automatic transmission drivers are the first to complain about fuel prices.

I had multiple DAFs some years ago, a 55 pseudo-Marathon, a diarhoea colored 46 SL, a totally rotten 66 SL and two Volvo 66s. Brilliant cars they are, strangely comfortable and so easy to maintain and tune, if you're into that. Back in 2008 they were not that expensive to buy, ranging from €300 to around a thousand. They all proved to be pretty reliable too, I used them as a daily and not very mildly, I have to admit. I remember having to change balljoints on my orange Volvo 66 and I could not get original ones but then someone told me balljoints for a 340 should fit as well. Well, they did fit alright, wit an added bonus of now having big negative camber on the front wheels, brilliant! That car taught me how to go round the roundabout properly. Sideways all the way, yeah, haha. I loved that car so much

The only good cvt I have seen was the one in my friends 2007 hybrid camery and Toyota did I call it a hybrid cvt as there is a physical gear used to get you moving and then the cvt takes over once your moving

Mitsubishi were handing out 10 year warranties so I figured that it really wasn't my problem, plus I'm not a crazy driver.

The one on my snowmobile

Great video I have had 2 mercs with cvt and only have praise for them very furl efficient and reliable I can understand why many font like them for the lack of perceived driving experience but it's no different to variable pitch propeller s on aircraft or variable pitch screws on ships, just the sensible option just don't fit one to a motorcycle where a proper geared transmission really matters

I think they have their uses. The problem is when they are pushed too far. I think we will need new materials if we expect them to be as durable as a manual transmission when high performance is part of the equation. Even on the low end, I question their long term durability as a whole. Many may last just fine, but I think there is a greater fail rate to them. Maybe they need to figure a way to use the CVT part to get to a specific final gear ratio, but then look that drive ratio to direct drive. But that wouldn’t help the high performance stress of getting up to speed quickly.

Honestly I don't trust any CVT except for Toyota's ECVT

Of the CVT designs I think the eCVT is the most promising. But I wonder is eCVT and electric transmission the same thing? Most trains today are diesel-electric. They use diesel engines to power generators, that then power electric motors. Isn't that really the same thing minus the battery? I wonder if we would ever see a modern example of this concept in a car.

CVT Transmission. ICE Engine. HIV Virus. PIN Number.

A "high power belt" sounds like something I need for my vehicle. And pants.

Toyota prius and honda freed are the best cvt vehicles ever created.

Even though I prefer regular transmission, not all are bad especially newer toyota e cvt they actually are very reliable and very rarely have any problems,possibly more reliable than regular toyota A/T but that is only in hybrid models as video states.

informative video

It’s not for heavy hauling! Period!

Toyota CVTs has a dedicated launch gear before the CVT takes over. This greatly reduces wear for the CVT. A reliable assessment is needed for these.

I'm kind of disappointed that you only mentioned Toyota for e-cvt. While other brands (Honda, Ford, etc.) also use the same setup in their hybrids.

CVTs are fine for average Mom and Pop drivers. Agressive "performance" drivers not so much.

The Holy Quran❗..👍👍👍🎧Search❔❔

I have a Ford PHEV. This uses the Toyota eCVT under license. It's very quiet, very quick and extremely smooth. I came from an 8 speed auto. The CVT is smoother. I like it very much. It also seamlessly brings in and stops the petrol motor as required.

A I'm 75 years old and had 26 cars during my Life I have had all types of transmissions and now CVT which is pleasing, particularly in traffic jams for 3 years so far no problems.

Maybe the widespread hate of these transmissions originated from the Nissan Micra CVT, the Honda CVTs and mostly the Audi Multitronic. These are idiot designs, and they fail pretty often.

My mums 2010 Mitsubishi lancer has a CVT transmission in it and she has owned it since new,never had any issues with it and it has 260,000 ks on the odometer.

E cvt is the best

I’ve always thought a simply CVT should couple up between a turbocharger & a engine, so when there’s not enough exhaust pressure to drive the compressor, it will work off the crank like an crank driven centrifugal supercharger, which is in effect what it will operate as. Then was the turbo spools out, the gearing of the belt ill change, so as well as compressing the intake gases, it will add power to the engine from the spinning turbo itself. In post WWII aero engines this was known as ‘turbo-compounding’.

They are not reliable. CVT's are a waste of time.

The T in CVT stands for Transmission. Everytime you say CVT Transmission, you are saying Continuously Variable Transmission Transmission. Sounds pretty redundant. You did this at least 4 times.

Among moped fans, Peugeot and Motebecane have fared well with CVTs.

A good friend of mine bought a Suzuki Scross with the belt and it went Kaput with only 80.000 km the good thing was the Suzuki importer in the Netherlands took over the guaranty and gave a new automatic for zero cost, so thatch the good thing but he sold the car shortly after and bought an Suzuki Scross with an conventional automatic gear box much to his satisfaction

CVT go from bad to worse. They suck! Only non car people like them.

The launch gear is more for reliability than performance. The most stress on a cvt is from a stand-still, especially when 'launching'. The regular cvt principles boggle my mind. The last thing you want in a transmission or engine, is friction, or slip. Once a cvt starts slipping, it's cooked, and all it wants to do is slip. Pushing a 1.5 ton car with over 100 bhp on such tiny contact surfaces is ridiculous. Just make you're on top of your oil changes. The Toyota E-CVT / power-split device, on the other hand, is genius, and virtually indestructible because, suprise, there is zero friction or slip between contact surfaces, like there is on a clutch, cvt, or torque converter. That's the only cvt-like transmission that I'd trust. It's electric motors, and gears spinning around, the last thing to break on those cars will be the transmission. That or Honda's E:Hev, but it's not really a CVT, more like an EV with a big generator, and a mode that drives the wheels at high speed with the petrol engine. These are fine too, low stress components, even the 'overdrive' clutch.

I have a honda cvt and it is quite good!

13:23 Toyota is far from the only Hybrid manufacturer that uses a eCVT.

I get about 70 mpg on the ecvt in my car. They work well.

the only cvt that is reliable is an e-cvt which is basically a generator hooked to the engine and electric motor driving the car. The rest will eventually fail...

I only have experience with the e-cvt in a Toyota Yaris. I like it. Obviously it will not make happy someone who drives because they like driving. But if your car is purely a tool of transportation this system is pretty good. Your accelerator pedal has nothing to do directly with the engine. You use it to tell the car how much power you want. The car then decides how much rpm is best to give you what you asked for and until the engine reaches that output the car will do its best to use the electric motor/generators to supplement it. Some people don't like it when the engine is keeping constant rpm while the car is accelerating. But as an engineer I like it. It just makes sense to have the engine rpm proportional to the power output and not tied to wheel speed. When I hear the engine in that car I am hearing how much power I am asking it to make and it is proportional to all the things like slope of the hill, speed, current acceleration etc. It just makes sense to me that the engine sound changes the way it does rather than linearly with just speed.

CHANGE YOUR CVT FLUID OFTEN!!! Unless you like walking 🚶 😊

I want to put a CVT on a multi-rotor turbo Wankel engine and go to the salt flats. Top speed baby!

Toyota’s Launch Gear is excellent!
