@@DCkevantnet the subaru and maxda CVT maps are the worst. Nissan at least recognizes its function but no one ever services them. I’ve had customers with 230k+ miles on their CVT’s because they service then every 25-30k miles.
When done right CVT is awesome. When done wrong you get a under powered rubberbandy mess. I once had the thought of a CVT "manual" where the shifter is you can select if you want to be geared to efficiently or peak power, or in between.
Was just testing my 2015 altima’s performance and not even gonna lie it’s a lot better than some things I’ve driven it’s been my daily for a little under a year and I gotta tell ya it’s fun, reliable, and cost efficient can’t get any better than an altima when it comes to a good daily!
FIA was probably contacted by Ferrari (knowing how they used to act) to ban the transmission. The CVT powered Williams was reported to be around a second or two faster than the conventional 6 speed ones. Which is sad, because if F1 were to keep developing the cvt, we could've gotten the best transmission ever made.
Ruining the CVT to give it fake "gears" to make people more comfortable is the entire reason most people hate them, as it's what causes most of the downfalls people attribute to them. Maybe with the rise of gearless electric cars, people will start to see the light in regards to real CVT transmissions.
Not true. I mean conceptually you’re right, fake manual shift points ruin the entire point of CVTs, but the part you got wrong is why people hate them. They’re hated because they’re extremely expensive to maintain and repair and often can’t be repaired at all because they’re sealed units. It’s the same reasons people hated DCTs at first too. Even Subaru’s high performance CVT in the new “WRX” has had a slew of reliability issues in under 70,000 miles.
@@Caffeinated-DaVinciI rented a Nissan Altima recently and by far the worst thing about it was the gearbox. I hated that car and maintenance was completely irrelevant to me.
@@Caffeinated-DaVinci A CVT, if properly made in the first place, should require less maintenance than a normal transmission, which already doesn't require maintenance for a really long time. CVTs are, by design, significantly less complicated than normal transmissions. They have fewer possible complications.
Not really tho. Just the fact that not much development has been put into them. CVTs are very prominent few years ago, but it loses because companies find surging money into developing a decent new transmission is too expensive. Also, about the F1 thing the guy mentioned, yes it was banned due to OP-ness of CVT, but even the car that used it had to switch back to conventional trans bcuz the engine couldn't hold the constant stress being always at the redline.
@ravioliravioli693 It wasn’t clear, but it was in relation to F1. Williams designed a CVT, and it was banned before it was even used. Williams didn’t really care anyway, they were better than the modern road car rendition of the CVT, but they were engine killers. Constant max hp+torque with no breaks on an already extremely stressed engine is a big boom waiting to happen.
@@markoj3512 yeah he is right a cvt is more efficient. Arguing with this guy is going to flick back in your face very quickly, he can do the math right in front of you without missing a beat.
It's not only about efficiency it's also about reliability and because cvt are belt driven, chain driven, and roller driven they tend to have more issues the conventional automatic and manual transmissions.
So you mean it's impossible to damage the gears inside your conventional transmission? Oh wait... If it's not a garbage CVT, it's probably going to be fine, not great, not terrible.
@@JMurph2015 I'm not talking about what's impossible to break, I'm talking about normal wear and tear. The fact is manual transmissions are the simplest and most reliable transmissions and the second most reliable transmissions are conventional torque converter automatic transmissions.
I'm a huge fan of CVT as a concept. Instead of compromising torque for higher gear or vice versa, CVT can always keep optimum balance, and it has infinite options. Reliability is however an issue. Once it gets solved, CVT will blow all other transmissions out of the water.
@@JMurph2015when your CVT blows up (and it will) you throw it away. My manual gearbox synchros wear out, making it more difficult to shift. It doesn’t blow up. I rebuild the box and keep on trucking.

It was banned in f1 because at the time the FIA saw it as a money pit in which Williams, Benetton, Ferrari and McLaren could easily develop to run away from the midfield
Not to mention having a static engine rpm exhaust sound regardless of speed would just sound awful. They would get it to the point where the gear ratio "changed" while the rpm never did to make peak power all the time.
As an automotive mechanical engineer, my immediate thought also went to CVT. I’ve never owned one my entire life, but I used one as a work car for about a decade (2014 Corolla). Toyota has been using it since the 90s-2000s on their early gen Prius.
@@jonahfastre it only feels like a traditional CVT, but internally it is totally different. A cvt uses a belt for infinite gear ratios, where Toyota E-CVT uses a planetary gear set that can be powered by 3 sources, 2 electric motors and the ice engine ( only 2 work at a time)
My subaru does a wonderful job engine breaking when cruise control is on and going downhill. That was honestly the thing that I was most excited about with a cvt.
That can be done with a manual transmission with much better results and much longer service life. I use engine braking as much as the hydraulic braking. In winter, I only use the engine braking, except for the last few meters to come to a complete stop. The hydraulic brake is far worse than the engine braking in ice, snow, sleet.
@indridcold8433 Yes, I know you can do it with a manual. You can also do it with an automatic that has manually selected gears. But I like that the vehicle maintains the set speed while adjusting the level of engine braking on its own. It's pretty neat and easier than choosing a gear to be in.
@@SHARAraTH i am assuming you are Indian and have drove one of these to be commenting like this....now let me share my experience...i have been driving activa since the past 11 years as my go to ride for nearby shops yet i haven't had any problems with the transmission...in fact i drive very rough while being careful always giving full throttle whenever i have free road ahead...even then My transmission is yet to fail me so i dont know what you are talking about ....can you please elaborate?

The cvt performed extremely well in testing with Williams. Over 4 seconds a lap quicker back in 93 against another f1 car with a semi auto sequential. Bearing in mind this was the FW15C@@ROBMACDUI
the problem is it sounds weird bc it's at peak power all the time. and the belt needs to be very flexible and very tough at the same time. the materials for that are really really expensive. I'd rather have a real gearbox.
@@JTheraos "Metal" is a very generic term. There's a little more to it, if it's for a vehicle that is carrying ppl. most cvt gearboxes get used in stepper motors and such.
For strength I’d never use a CVT, I’ve been around drag cars my whole life, prostock, and promod, with the occasional funny car thrown in. I think the Lenco is about as strong as they get. Based on what I’ve seen. But anything thats gear to gear will hold up really well
Just exactly how does your drag racing experience have relevance to an everyday car that the driver would like a bit of performance from? You are talking the damage multiple of a thousand horse power delivers to a drive train verses what a few hundred does. My sole experience with a CVT was driving a friend's Maverick High Bred for 1600 miles. Smooth operation. Great acceleration. 47 mpg when driving the speed limit on the highway. I'm sold.
Just look at power sports vehicles like SxSs and snowmobiles, theyre quick out of the hole with a CVT but frankly as they get up in speed acceleration dies. Resistances build there is just too much load on that CVT to get the pullies to engage properly. Theyre compact thats why their used, a geared transmission would be massive to operate as variable as a CVT, and they would require too many shifts. The theory behind a CVT is sound, the actuality is another story.
@@johnhunter7244 you're not wrong but they still require maintenance and downtime that a manual or even an automatic don't require. The good thing about CVTs in the powersports world is they're small and are not used as frequent as a daily driving vehicle so maintenance can be done in the off season and it's relatively inexpensive, pull the clutches off, replace springs, rollers, belts and so a cleaning and slap it back on. A car is a very different animal and the man hours to do simple maintenance on them is heavy and costly
CVTs with belts actually aren't the best. Those transmissions could be good in small cars. The problem is that A segment cars weigh now around 1000kg and often have 70-80hp just to be able to move. This would require more robust construction and more expensive belt. On the other hand Toyota eCVT is really an engineering masterpiece. It is efficient, rock solid and if you combine it with decent combustion engine the performance is also there.
Agreed. Honda, as well as Toyota, have impressive engineering in their hybrid transmissions. I think they just call them ecvts because they never bothered to make up a new name, and most of their customers don't care, but they know the term cvt. Neither one works without electric motors, though.
This is why CVTs aren’t used literally everywhere. They can’t handle high torque with current construction methods and materials. But they are the best type of transmission because they do perfectly what transmissions are supposed to do. (Except you know transmit high torque, lol) Every other type is a compromise.
I really liked my 2011 Maxima’s CVT. So smooth. Just change the fluid every 30,000 miles or so & it will last. Mine had 180,000 when I sold it. I drove it hard too
@@EngineeringExplained Growing up (Gen X) I concluded that both "nerds" and "dorks" were highly introverted and socially awkward, but nerds were into academic things and dorks were into minutia. "Geeks" were either less-introverted or even extroverts, and into science/engineering academia and/or technology. So you are clearly a "geek" like myself and many others. Welcome to the club!
the F1 CVT never finished a session. They were fast while they worked but didn't work for long enough to be able to finish a race that's why Williams didn't protest the ban Now imagine a world where CVTs did get F1 development...
One little detail: CVT can’t hold any really big torque. It’s literally impossible to make it small and light enough with some torque capacity. In contrast, Audi dual clutch DQ500 from RS3/ RSQ3/ TTRS can hold up to 1000 nm on bone stock clutches and gears (you just need a little software magic to it) while it’s super small and light
It's totally possible, but car manufacturers judt haven't done it yet. Diesel farm tractors have been using CVTs for nearly 20 years, and they put out at least 500 foot pounds of torque
@@lsorenseVery little construction use cvt, they are almost exclusively driven via hydrostatic. Tractors however have been using cvts for a couple decades now. Although there is talk (mostly from new holland) to not use them on gas powered tractors, as those engines need all the power they can produce and can’t deal with the 10-20% power loss that cvts can result in.
Of course CVT can, it just that it cost way more to manufacture one with the right materials and design to hold that torque. Like the video said, F1 (Williams I believe) used it for their car. If it’s enough to hold F1 level torque it’s fine for your normal 600hp high performance sports car
A “working” CVT has 4 modes, 1. minimum RPM, 2. riding the torque (~2600rpm 2011 Suzuki SX4), 3. Floored, 4. Stop reving so high absolute trash so much noise and it isn’t even going anywhere! Actually on the 2011 SX4 there are two additional modes, 5. E1-6 “manual” which is primarily for descending mountain roads by engine rather than brakes, but E3 can be used for flooring from 35-60mph for on ramps to prevent slippage that would normally occur when flooring it. E1 can be used in snow with fully locked AWD for crawling through the slushiest winter mess and E2 can be used for 20-34mph fully locked AWD in winter slush so that you can control any traction issues with the gas pedal. Mode 6. You went past 8K miles from last transmission fluid change and there is all manner of rpm fluctuation because of constant slippage in the transmission and it will be another 2K mileage of slippy nonsense before it gets worked out and you need to do another CVT fluid change so whatever was in the sensitive parts that caused all the slippyness to begin with doesn’t get back in… but you can sort of override that by using E5 or E6 “manual” depending on wind on highway so that the car is at least drivable. Would I ever recommend a CVT? Nope! If there isn’t a manual override you won’t even be able to drive it if you go a little past your cars individual CVT fluid change intervals.
My rover 25 1.6 CVT was a beast! Had 110hp but somehow i could keep up with 200hp cars. In normal mode it would go up to 4k rpm when full throttled but in sport it would shoot to 7k and stay there the whole time. You’d think the car was going to blow up but the little beast flew with no shifts in sight. Made it smooth and easy to drive!
@@cj1richt You clearly never driven a cvt car without fake gears so please don't make ridiculous assumptions like they always keep engine at peak power. I drive a cvt and it can accelerate from 0 to 100 while keeping the engine at 1800rpm with a gentle gas input. Engine rpm it holds depend on how much you press the gas pedal and which driving mode you are on. If I put it to sport and give full throttle, then the 0 to 100 will be done while keeping the engine at 6500 rpm.
Because the public at large does not easily adapt to change. Same reason Ford pipes the sound of a V8 into the cabs of trucks powered by turbo V6 engines.
Invented in my back garden so to speak (Eindhoven Netherlands) My mum had a DAF 55 in the late ‘60’s early 70’s we’d always egg her on to win sprints away from the traffic light.

What your mom really needed to do was reverse to the stop light, then hammer that 34hp twin for everything it was worth. Bet you she would have won more than her share of stop light drags with that one weird trick. 😅
I bought my '16 Maxima SV new, I now have 161,000 miles. Still pulls like a train. I monitor/change all liquids in this car, not just the oil. No major issues with this car ever. My last car was an '07 Altima 3.5SE with 170,000 miles. (I'm a mechanical engineer, but I design tooling, not cars).
I sometimes drive a somewhat older (2012 I think?) audi with a cvt. At the end of their lifecycle, they actually made them pretty reliable. 200.000+KM down without a hitch. Many Toyota hybrids as well.
My 2015 Nissan Sentra has a CVT and... I've had to buy a whole new transmission just 9 months after buying the car, then 2 years later I figured out why, and it's exactly this... you need a fluid change every 30k - 60k miles depending on frequency of use and how uphill you drive, it's my daily driver and there's hills everywhere so... that made my brand new transmission crap out yet again at only 20k miles, luckily I got a fluid change soon and everything has been alright since, but nobody (not even the people who installed my transmission) told me it wore out faster uphill
I'm not a CVT fan at all. Nissan's seem to be junk. My wife has one in her Subaru that has 70000 miles on it now and it hasn't had any issues. We are also very diligent about it's service though.

@MrJord1994 that's why the #1 priority of you want to build a successful road car is low maintenance requirements. And yes, this also applies to sports cars.

Regular CVTs in car applications are usually powered via a torque converter though which decreases effiency in any real world application A LOT! Upwards of 25% if enough stop and go!
Should have warned viewers that they dont last for everyday driving in civilian vehicles. Maybe good for one race, but should be banned or come w mandatory lifetime warranty for civilians. They're always put in vehicles that old ladies drive and can least afford 7k for a new one

@@kennichdendenn Toyota hybrids do not use a cvt transmission. The cvt is only one part of the transmission. The Toyota cvt with launch gewr seem to do well too. It is the single speed wide ratio stuff that fails very quickly and is a plague on the industry and are not more efficient with American road speeds.
@@BiglyDownUnder I think Toyota did class action lawsuit settlement warranties on their single speed engine driven cvt as well. They only use those in a few lower end cars. When people think the Toyota cvt is the only good one, it is the Prius one or the launch gear one. The Prius one is only part of the system and has little load on it. The launch gear one uses it as overdrive and it had a narrow range. It is also never used from a stop. As of now every engine driven single speed belt on cone (rubber, steel, or chain belt) had major reliability issues. They should not be in consumer vehicles unless they are easily servicable like in ATV and snowmobiles.
All that goes out the window when the car has to frequently accelerate from a stop. Belt and pulley CVTs are weak by design and cannot handle torque which is the reason no self respecting car company would put one in a performance vehicle or one built to tow.
Thats why Honda added a launch gear to their CVTs, car starts off in 1st gear during acceleration and when it reaches a certain speed, it switches to the cvt. Tremendously removes stress off the CVT and increases their reliability.
I knew they put CVTS in side by sides and UTVS, fourhweelers and small machines like that but I didnt know they could be used in racing. I dont imagine those gears doing very good at holding high speeds for long durations of time because of the constant friction on the same gears
If you've ever grabbed a fist full of throttle on a snomachine and hang on for the ride, its the closest thing felt to linear power in a combustion engine via a CVT. And the ability for it to back shift to the perfect ratio for another fist full of power is also impressive.
The fun part? Go-Karts use these. The other thing though. for racing their fine, because a race isn't usually months of driving. For Day to day driving, They really can leave you high and dry if you don't know how to drive them properly and maintain them. That's the key, maintain. They are functionally a 150k Mile(~241.4 KM) transmission if you take care when using one. They however, can be dead by 24k miles (~38.6 KM) with running them hard, breaking the belt, not flushing the system, etc.
In my thought the CVT is ideal to compensate the issues combustion engines have due to the (narrow) bandwith of useable rpm. But sadly it has much friction losses and durability problems. And, if programmed bad, it becomes unpleasant to drive.
I sometimes drive my mom's CVT Honda HR-V. It's insane how weird it sounds at first, especially on the highway when you floor it for an overtake and the engine ups the revs and keeps itself in the power band until you let off again.
My brother had a 2012 audi a4 cvt he modified the car, and the cvt blew out because of the power. Well, he got a new one and modified the components of the cvt, and it was actually very fast and fun. i really loved it. My favorite gear types are manual and cvt automatic gears. It was great, but the only problem with cvt is that when you are on a hill, it rolls back and jerks, so if someone is behind you just know you will roll into them if you dont give it any throttle power, also when you start moving it always jerks then moves thats how cvt is but for the rest it is a great car or transmission
When the clutch is pressed just enough to use the gear box it’s still possible to use any gear and engine break at the same time as well as using the breaks.
Alot of people are probably gonna spaz on me but their 3rd Gen Kia soul with the CVT works great. Easy to maintain and gives me roughly 40mpg. Gives me power when I need it and doesn't try to be a traditional transmission even though it's advertised as "mimicking a 6 speed auto.
A sequential with a correctly set up strain gauge, up and downshift rev matching is the ultimate transmission set up for anything other than drag racing.
The only downside to the Continuously Variable Transmission we drove was that it could not climb gravel hills because of too much torque. Excellent in every other condition until it failed due to poor maintenance.
I ran a CVT maxima at the dragstrip. It’s the only car I’ve ever tested that was slower putting the transmission in sport mode. It actually turned a slightly better time consistently in regular mode where it just held the RPMs at peak power. In sport mode it mimics a traditional transmission with gears and it did cost it time and speed. It was completely stock and its best time was a 9.0 @ 80 MPH. A truly impressive time for a full size sedan with a 3.5 V6. But something to consider is that this test was simply hold it to the floor in a straight line and let off. It does not seem like the CVTs in most cars are capable of finding the right ratio in a split second every time when flying through turns like a modern dual clutch automated manual. Maybe it could be developed for racing where they could but the ones I’ve driven aren’t that capable and would probably overheat and destroy themselves if you tried to run a race like that with them.
My Subaru CVT is slower in manual mode to 60mph than it is in CVT mode. And top speed is higher, too. Fastest I've gone in manual mode was about 121mph vs 129mph in CVT mode.
One thing to know about CVT's is that the power from the engine is transfered to the wheels with just a belt. With that in mind, a CVT can't take as much stress as a traditional transmission, so you'll have to take care to avoid driving in the mountains when you can and not floor it too much when moving. This is also why it's only in small vehicles.
It's a metal chain in most cars. They drive in mountains just fine. Stop spreading BS. They aren't the most high performance option, but they work fine for most people (unless you bought a Nissan, that's on you).
Yea baby Subaru! Honestly one negative os id your driving down the freeway and all of a sudden have to gun it, it has to ramp down to the right gear where a hydro can just instantly change to that lower ratio. Another is the possibility of slip failure over time or due to high torque applied
Just a small correction, CVT cant choose ANY ratio, it can choose a ratio within the designed specs. For any ratio you would need a “endlesly small” small sprocket, and a “endlessly big” big sprocket.
Also because F1 CVTs just kept burning themselves up due to being constantly at peak power. They also burned up fuel like crazy because it's always at peak power despite using that power really efficiently
Did you know that Michael Schumacher crashed into the ‘Wall of Champions’ during the 1999 Canadian Grand Prix due to a shifting error? He accidentally selected the wrong gear while approaching the final chicane, causing him to lose control and crash. Imagine if CVTs were allowed - they could provide smoother and safer handling, especially in tight corners.

Yep, and this dork was not right. Cut has a terrible efficency compared to a regular manual shifting gear box
@@markoj3512 yeah he is right a cvt is more efficient. Arguing with this guy is going to flick back in your face very quickly, he can do the math right in front of you without missing a beat.
@@markoj3512and you'd be wrong.
It's not only about efficiency it's also about reliability and because cvt are belt driven, chain driven, and roller driven they tend to have more issues the conventional automatic and manual transmissions.
So you mean it's impossible to damage the gears inside your conventional transmission? Oh wait...
If it's not a garbage CVT, it's probably going to be fine, not great, not terrible.
@@JMurph2015 I'm not talking about what's impossible to break, I'm talking about normal wear and tear. The fact is manual transmissions are the simplest and most reliable transmissions and the second most reliable transmissions are conventional torque converter automatic transmissions.
I'm a huge fan of CVT as a concept. Instead of compromising torque for higher gear or vice versa, CVT can always keep optimum balance, and it has infinite options.
Reliability is however an issue. Once it gets solved, CVT will blow all other transmissions out of the water.
@@JMurph2015when your CVT blows up (and it will) you throw it away. My manual gearbox synchros wear out, making it more difficult to shift. It doesn’t blow up. I rebuild the box and keep on trucking.

Toyota ECVT is more like a conventional automatic with planetary gears.
@@kniebanwith planetary gears, but without the brakes, clutches, and actuators. IE: the unreliable bits.

Same the new Honda CVT at least in my civic is smooth. You can reasonably get to 50 without going over 2k-2.4k rpm, it's crazy
It was banned in f1 because at the time the FIA saw it as a money pit in which Williams, Benetton, Ferrari and McLaren could easily develop to run away from the midfield
Not to mention having a static engine rpm exhaust sound regardless of speed would just sound awful. They would get it to the point where the gear ratio "changed" while the rpm never did to make peak power all the time.

As an automotive mechanical engineer, my immediate thought also went to CVT.
I’ve never owned one my entire life, but I used one as a work car for about a decade (2014 Corolla). Toyota has been using it since the 90s-2000s on their early gen Prius.
E-CVT is not CVT
@@slick1908 for an automotive mechanical engineer, his knowledge is limited.
@@manishalu7415Every one is an engineer now adays 😅
@@slick1908in what way is Toyotas E-CVT not a CVT then?
@@jonahfastre it only feels like a traditional CVT, but internally it is totally different. A cvt uses a belt for infinite gear ratios, where Toyota E-CVT uses a planetary gear set that can be powered by 3 sources, 2 electric motors and the ice engine ( only 2 work at a time)
My subaru does a wonderful job engine breaking when cruise control is on and going downhill. That was honestly the thing that I was most excited about with a cvt.
That can be done with a manual transmission with much better results and much longer service life. I use engine braking as much as the hydraulic braking. In winter, I only use the engine braking, except for the last few meters to come to a complete stop. The hydraulic brake is far worse than the engine braking in ice, snow, sleet.
@indridcold8433 Yes, I know you can do it with a manual. You can also do it with an automatic that has manually selected gears. But I like that the vehicle maintains the set speed while adjusting the level of engine braking on its own. It's pretty neat and easier than choosing a gear to be in.
Sequential transmission is way faster and louder than both 🥰

P.S. I always downshift to get engine revs up before sending it.
The problem is durability and reliability. They wear faster and can't handle to much power without slipping.
Then how does the F1 version differ?
@@SM-qe4wd I'm not to familiar with the f1 cvt. But I assume they are built to withstand slipping with increased wear as they only have to work for the race.
@@SM-qe4wdIt was rejected due to existing regulations stating that transmissions must have 4 to 7 gears. It never actually raced so no one knows if it was actually durable enough to last an entire race.
@@ROBMACDUI thanks!
The cvt performed extremely well in testing with Williams. Over 4 seconds a lap quicker back in 93 against another f1 car with a semi auto sequential. Bearing in mind this was the FW15C@@ROBMACDUI
the problem is it sounds weird bc it's at peak power all the time.
and the belt needs to be very flexible and very tough at the same time. the materials for that are really really expensive.
I'd rather have a real gearbox.
The belts are made of metal. They look complex as hell.
@@JTheraos
"Metal" is a very generic term.
There's a little more to it, if it's for a vehicle that is carrying ppl.
most cvt gearboxes get used in stepper motors and such.
For strength I’d never use a CVT, I’ve been around drag cars my whole life, prostock, and promod, with the occasional funny car thrown in. I think the Lenco is about as strong as they get. Based on what I’ve seen. But anything thats gear to gear will hold up really well
Nothing is stronger than hard gears. The belt driven CVT should not even exist in a car.
Just exactly how does your drag racing experience have relevance to an everyday car that the driver would like a bit of performance from? You are talking the damage multiple of a thousand horse power delivers to a drive train verses what a few hundred does. My sole experience with a CVT was driving a friend's Maverick High Bred for 1600 miles. Smooth operation. Great acceleration. 47 mpg when driving the speed limit on the highway. I'm sold.
It's a simplification. A CVT has more friction loses at higher RPM. It requires a high pressure oil pump that saps power.
Just look at power sports vehicles like SxSs and snowmobiles, theyre quick out of the hole with a CVT but frankly as they get up in speed acceleration dies.
Resistances build there is just too much load on that CVT to get the pullies to engage properly.
Theyre compact thats why their used, a geared transmission would be massive to operate as variable as a CVT, and they would require too many shifts. The theory behind a CVT is sound, the actuality is another story.
Also most CVTs (any I've seen, maybe not for F1) are powered via a torque converter which robs the most of the effiency away!
@@gtileoThey also need frequent belt changes if driven aggressively on high traction surfaces.
You can use a dry belt. We all use CVTs in SAE baja. I can change a belt in
@@johnhunter7244 you're not wrong but they still require maintenance and downtime that a manual or even an automatic don't require.
The good thing about CVTs in the powersports world is they're small and are not used as frequent as a daily driving vehicle so maintenance can be done in the off season and it's relatively inexpensive, pull the clutches off, replace springs, rollers, belts and so a cleaning and slap it back on.
A car is a very different animal and the man hours to do simple maintenance on them is heavy and costly
CVTs with belts actually aren't the best. Those transmissions could be good in small cars. The problem is that A segment cars weigh now around 1000kg and often have 70-80hp just to be able to move. This would require more robust construction and more expensive belt.
On the other hand Toyota eCVT is really an engineering masterpiece. It is efficient, rock solid and if you combine it with decent combustion engine the performance is also there.
eCVT is so good that it shouldn't be sorted in the same category as regular CVT
Agreed. Honda, as well as Toyota, have impressive engineering in their hybrid transmissions. I think they just call them ecvts because they never bothered to make up a new name, and most of their customers don't care, but they know the term cvt. Neither one works without electric motors, though.
can someone explain how a eCVT or beltless CVT works?
This is why CVTs aren’t used literally everywhere. They can’t handle high torque with current construction methods and materials.
But they are the best type of transmission because they do perfectly what transmissions are supposed to do. (Except you know transmit high torque, lol) Every other type is a compromise.
Perfect in my spark
I went to watch this dork you recommended. And to my surprise he seemed quite knowledgeable, I hope he gains more subscribers
I really liked my 2011 Maxima’s CVT. So smooth. Just change the fluid every 30,000 miles or so & it will last. Mine had 180,000 when I sold it. I drove it hard too
Changing CVT belt after every F1 race was another reason for banning. CVT reliability is horrible.
Is reliability horrible, or just the maintenance intervals horrible?

@@SSSSSSSSS-zx2ozefficiency 🥰
@@SSSSSSSSS-zx2ozno they didnt.
One little detail: CVT can’t hold any really big torque. It’s literally impossible to make it small and light enough with some torque capacity. In contrast, Audi dual clutch DQ500 from RS3/ RSQ3/ TTRS can hold up to 1000 nm on bone stock clutches and gears (you just need a little software magic to it) while it’s super small and light
A lot of construction equipment would disagree. They are not belt based though.
It's totally possible, but car manufacturers judt haven't done it yet. Diesel farm tractors have been using CVTs for nearly 20 years, and they put out at least 500 foot pounds of torque
@@lsorenseVery little construction use cvt, they are almost exclusively driven via hydrostatic. Tractors however have been using cvts for a couple decades now. Although there is talk (mostly from new holland) to not use them on gas powered tractors, as those engines need all the power they can produce and can’t deal with the 10-20% power loss that cvts can result in.
@@specialopsdave you can’t put tractor cvt in a car, there is no space for it
Of course CVT can, it just that it cost way more to manufacture one with the right materials and design to hold that torque. Like the video said, F1 (Williams I believe) used it for their car. If it’s enough to hold F1 level torque it’s fine for your normal 600hp high performance sports car
"what makes it so good" isn't the question i was asking when i rented a Toyota with a CVT. "Wtf is wrong with this transmission" is closer.
it doesn't sound like a normal transmission at all, certainly.
A “working” CVT has 4 modes, 1. minimum RPM, 2. riding the torque (~2600rpm 2011 Suzuki SX4), 3. Floored, 4. Stop reving so high absolute trash so much noise and it isn’t even going anywhere!
Actually on the 2011 SX4 there are two additional modes, 5. E1-6 “manual” which is primarily for descending mountain roads by engine rather than brakes, but E3 can be used for flooring from 35-60mph for on ramps to prevent slippage that would normally occur when flooring it. E1 can be used in snow with fully locked AWD for crawling through the slushiest winter mess and E2 can be used for 20-34mph fully locked AWD in winter slush so that you can control any traction issues with the gas pedal.
Mode 6. You went past 8K miles from last transmission fluid change and there is all manner of rpm fluctuation because of constant slippage in the transmission and it will be another 2K mileage of slippy nonsense before it gets worked out and you need to do another CVT fluid change so whatever was in the sensitive parts that caused all the slippyness to begin with doesn’t get back in… but you can sort of override that by using E5 or E6 “manual” depending on wind on highway so that the car is at least drivable.
Would I ever recommend a CVT? Nope! If there isn’t a manual override you won’t even be able to drive it if you go a little past your cars individual CVT fluid change intervals.
My rover 25 1.6 CVT was a beast! Had 110hp but somehow i could keep up with 200hp cars. In normal mode it would go up to 4k rpm when full throttled but in sport it would shoot to 7k and stay there the whole time. You’d think the car was going to blow up but the little beast flew with no shifts in sight. Made it smooth and easy to drive!
The 200hp car was a dodge caravan😢
@@2_persents just so happens we dont have dodge caravans in the UK 🤷♂️ but its ok I’m sure you’ll find someone else you can have jokes with 😂😂
That’s why snowmobiles have them, light, fast, simple
My Merc has a Cvt gear box and it's Awesome, ridiculous perfection, I've never looked back to manual
And why are auto makers like Subaru crippling their CVT's by assigning static gear ratios?
I wouldn’t think holding an engine at peak power would be good for reliability
Because people expect shift behavior and complain if it does something else
Because Subaru is desperately trying to mimic an auto to please enthusiasts instead of simply designing a decent non cvt transmission.
@@cj1richt You clearly never driven a cvt car without fake gears so please don't make ridiculous assumptions like they always keep engine at peak power.
I drive a cvt and it can accelerate from 0 to 100 while keeping the engine at 1800rpm with a gentle gas input.
Engine rpm it holds depend on how much you press the gas pedal and which driving mode you are on.
If I put it to sport and give full throttle, then the 0 to 100 will be done while keeping the engine at 6500 rpm.
Because the public at large does not easily adapt to change. Same reason Ford pipes the sound of a V8 into the cabs of trucks powered by turbo V6 engines.
Invented in my back garden so to speak (Eindhoven Netherlands) My mum had a DAF 55 in the late ‘60’s early 70’s we’d always egg her on to win sprints away from the traffic light. Never failed to win, even though the thing had only 12 hp or whatever😂 And yes, the fiber-reinforced rubber pull version then still on course. Sound was awful.
What your mom really needed to do was reverse to the stop light, then hammer that 34hp twin for everything it was worth. Bet you she would have won more than her share of stop light drags with that one weird trick. 😅
driving CVT and gaining speed while losing revs is simply the most infuriating thing Ive ever experienced driving a car

I bought my '16 Maxima SV new, I now have 161,000 miles. Still pulls like a train. I monitor/change all liquids in this car, not just the oil. No major issues with this car ever. My last car was an '07 Altima 3.5SE with 170,000 miles. (I'm a mechanical engineer, but I design tooling, not cars).
Surprising. Maxima's feel great with the CVT.
CVT:
Nissan Rouge has it. Does not last. Every 35k miles change the fluid
I sometimes drive a somewhat older (2012 I think?) audi with a cvt. At the end of their lifecycle, they actually made them pretty reliable. 200.000+KM down without a hitch.
Many Toyota hybrids as well.
Toyota e-cvt lasts forever without any maintenance. It almost never failed. Ever.
My 2015 Nissan Sentra has a CVT and... I've had to buy a whole new transmission just 9 months after buying the car, then 2 years later I figured out why, and it's exactly this... you need a fluid change every 30k - 60k miles depending on frequency of use and how uphill you drive, it's my daily driver and there's hills everywhere so... that made my brand new transmission crap out yet again at only 20k miles, luckily I got a fluid change soon and everything has been alright since, but nobody (not even the people who installed my transmission) told me it wore out faster uphill
CVT just needs slightly more frequent fluid changes. People who have had failed ones fall for the whole lifetime fluid scam.
tell that to Nissan that felt the need to make a crappy version of this.
When I worked at a Nissan dealer, I have seen them fail before hitting 1000 km's in a new Juke or Quashqai.

The launch gear one uses it as overdrive and it had a narrow range. It is also never used from a stop.

Totally agree my friend! Loving my Crosstrek!
Yep, thanks!
I drove my mom's Suzuki Swift that uses a CVT, and it sure is fast. the acceleration on that tiny car is crazy
All that goes out the window when the car has to frequently accelerate from a stop. Belt and pulley CVTs are weak by design and cannot handle torque which is the reason no self respecting car company would put one in a performance vehicle or one built to tow.
Thats why Honda added a launch gear to their CVTs, car starts off in 1st gear during acceleration and when it reaches a certain speed, it switches to the cvt. Tremendously removes stress off the CVT and increases their reliability.
@@misterbaxter3734 I wasn’t aware Honda did this. Thought it was just Toyota.

I knew they put CVTS in side by sides and UTVS, fourhweelers and small machines like that but I didnt know they could be used in racing. I dont imagine those gears doing very good at holding high speeds for long durations of time because of the constant friction on the same gears
I don't know, I don't really like CBT but you do you ❤
My car has cvt but i love the feeling of gear shift
If you've ever grabbed a fist full of throttle on a snomachine and hang on for the ride, its the closest thing felt to linear power in a combustion engine via a CVT. And the ability for it to back shift to the perfect ratio for another fist full of power is also impressive.
The fun part? Go-Karts use these.
The other thing though. for racing their fine, because a race isn't usually months of driving. For Day to day driving, They really can leave you high and dry if you don't know how to drive them properly and maintain them. That's the key, maintain. They are functionally a 150k Mile(~241.4 KM) transmission if you take care when using one. They however, can be dead by 24k miles (~38.6 KM) with running them hard, breaking the belt, not flushing the system, etc.
In my thought the CVT is ideal to compensate the issues combustion engines have due to the (narrow) bandwith of useable rpm.
But sadly it has much friction losses and durability problems. And, if programmed bad, it becomes unpleasant to drive.
As long it is not a Nissan/Renault built one. You are good!!!!
I sometimes drive my mom's CVT Honda HR-V. It's insane how weird it sounds at first, especially on the highway when you floor it for an overtake and the engine ups the revs and keeps itself in the power band until you let off again.
When I took auto mechanics in college in the 1980s my teacher talked about the CVT being introduced
Also used in MTD lawn mowing equipment a real pain to change the belt
My brother had a 2012 audi a4 cvt he modified the car, and the cvt blew out because of the power. Well, he got a new one and modified the components of the cvt, and it was actually very fast and fun. i really loved it. My favorite gear types are manual and cvt automatic gears. It was great, but the only problem with cvt is that when you are on a hill, it rolls back and jerks, so if someone is behind you just know you will roll into them if you dont give it any throttle power, also when you start moving it always jerks then moves thats how cvt is but for the rest it is a great car or transmission
Beating the og pong with 5 counters with 3m is just peak brilliance on full display.

I ran a CVT maxima at the dragstrip. It’s the only car I’ve ever tested that was slower putting the transmission in sport mode. It actually turned a slightly better time consistently in regular mode where it just held the RPMs at peak power. In sport mode it mimics a traditional transmission with gears and it did cost it time and speed. It was completely stock and its best time was a 9.0 @ 80 MPH. A truly impressive time for a full size sedan with a 3.5 V6. But something to consider is that this test was simply hold it to the floor in a straight line and let off. It does not seem like the CVTs in most cars are capable of finding the right ratio in a split second every time when flying through turns like a modern dual clutch automated manual. Maybe it could be developed for racing where they could but the ones I’ve driven aren’t that capable and would probably overheat and destroy themselves if you tried to run a race like that with them.
My Subaru CVT is slower in manual mode to 60mph than it is in CVT mode. And top speed is higher, too. Fastest I've gone in manual mode was about 121mph vs 129mph in CVT mode.
Its also a maxima
I got a feeling you have a Nissan Altima. Me too lol 😅😅😅
One thing to know about CVT's is that the power from the engine is transfered to the wheels with just a belt. With that in mind, a CVT can't take as much stress as a traditional transmission, so you'll have to take care to avoid driving in the mountains when you can and not floor it too much when moving. This is also why it's only in small vehicles.
It's a metal chain in most cars. They drive in mountains just fine. Stop spreading BS. They aren't the most high performance option, but they work fine for most people (unless you bought a Nissan, that's on you).
Yea baby Subaru! Honestly one negative os id your driving down the freeway and all of a sudden have to gun it, it has to ramp down to the right gear where a hydro can just instantly change to that lower ratio. Another is the possibility of slip failure over time or due to high torque applied
Just a small correction, CVT cant choose ANY ratio, it can choose a ratio within the designed specs. For any ratio you would need a “endlesly small” small sprocket, and a “endlessly big” big sprocket.
Also because F1 CVTs just kept burning themselves up due to being constantly at peak power. They also burned up fuel like crazy because it's always at peak power despite using that power really efficiently
Did you know that Michael Schumacher crashed into the ‘Wall of Champions’ during the 1999 Canadian Grand Prix due to a shifting error? He accidentally selected the wrong gear while approaching the final chicane, causing him to lose control and crash. Imagine if CVTs were allowed - they could provide smoother and safer handling, especially in tight corners.
CVT brings my thoughts to the old Daf/Volvo 66 Variomatic
WAIT!!,, I remember when Nissan dealerships played those video fragments of the CVT all the time
