What's The Fastest Transmission? Don't Hate The CVT!

- What’s the best transmission? A dual clutch transmission might come to mind due to their lightning quick shifts, but there's another transmission that can allow you to go even faster. As it turns out, a CVT, or continuously variable transmission, reigns king in terms of efficiency and performance. There's a reason the technology was banned after its use in Formula 1. What makes it so good? Well a CVT can choose any gear ratio within its range at any given time, and it can constantly change that gear ratio. That means it can simply hold the engine at peak power, meaning the quickest acceleration, and change the gear ratio as the vehicle’s speed changes, never taking the engine off peak power.
Why hold at peak power, and not peak torque? Learn more here:

Yes. Don't ruin the advantage of the CVT.
my car has that fake manual lmao, the ratio changes to simulates manual like damn just give me high ratio for cruising and low ratio bor accelerating, im in no goddamn Lamborghini Urus 😭😭😭
That’s why most CVT’s die out early. The “feedback” programmed is a band killer.
I'm sure any good tuning company can get that fixed.
@@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.
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.
But let’s be honest we all prefer the sound of cars with regular gear boxes

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.
Look up electronic cvt. It already exists. You can set the desired rpm range.
CVTs are weak transmissions. They are only good for fuel efficient low powered vehicles.

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.
Ok forget drag racing. Look at the pitiful towing capacity of the maverick. It’s like less than 2,000 lbs. also note that trucks and large SUVs don’t use cvt. If you follow mechanic podcasts and accounts, then you will also see that cvts are not long lasting, even in little cars. Nobody rebuilds them, you just get a new one and create a bigger carbon footprint
Doesn't worth arguing with them. Efficiency can be understood as "profit for who's selling CVT cars". Now Lencos are something I'm definitely curious about ... never seen these in my country
Has nothing to do with the trans and everything to do with the overall weight of the truck. @@GMK6300L
"Too big of an advantage"
He meant by: big companies couldn't bear to lose to smaller companies, soo they just lobbied to ban them.
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.
The real problem is reliability.
@@ravioliravioli693yeah that f1 with CVT just burned itself out after a few laps
@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.
@ravioliravioli693 Didn’t read the whole thing, disregard that.
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.
also those weird knob shifters
Its just not fun.
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.

Same here with 3 Subarus
Why the new Nissan CVT is not reliable as before?
That's quite impressive considering how many issues the early models had

@@markoj3512and you'd be wrong.
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.
they just was tryna keep nissan out the f1 game
@@rabbitdrink lmao
@@evozero905Indeed, the sound of gear changes is incredibly therapeutic.
And because it was 4 seconds a lap quicker, just saying 😂
This is true my 2017 Civic with a 1.5 turbo CVT tuned to 260hp walked away from a TYPE R and a STI of same year. Just stayed at peak power while they had to loose boost to gears
The ECVT in Toyota hybrids solved the rubberband feel. No belt, no shifts, maximum efficiency and smooth power delivery
yup, the planetary gearset is great.
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.
My car has an eCVT and I absolutely love it. It is so smooth.
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
Just need to ride a moped/scooter with and without a variator to get a full appreciation for the CVT

People will say that cvts will slip, they don't. They used to but they have since fixed the issue by using solid metal belts instead of rubber.
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)
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.
I have nothing against CVTs. They are my job security. Nissan CVTs are so bad that our shop keeps them in stock. That should tell you something right there.
That’s why snowmobiles have them, light, fast, simple
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
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 🥰
@indridcold8433 Any engine can engine brake
My VW does it too and it has a DSG.
Cvt would be a great transmission if they were built stronger but im sure somebody out there builds one that dosent need rebuilt every 100k or can handle aome power would be nice if they all were built strong!!!!
Invented by a Dutch man and developed in the fifties and sixties, released in 1958 for DAF vehicles. Called variomatic back then.
Yup - I had one of those DAF Volvos - '300' series! Nasty execution, in that instance - band always breaking.
What folk struggle with psychologically is hearing one, single engine note (peak power RPM) - while the car drives at very varying speeds.
It is a very odd experience!
Correct
@@ArifGhostwriterI just bought one. It is strange, like , with the turbo, it's hard to judge your speed when overtaking, i"m always going faster than I think. I'm sure I'll get used to it.
P.S. I always downshift to get engine revs up before sending it.
Wikipedia says it was invented by Milton reeves in 1879.
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
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?
Cvt’s only really suck from nissan but if they spent a few million on designing a new one it would take the skill out of shifting gears for drivers

The eCVT on the Toyota Ractis and Vitz has been the smoothest transmission I've ever used
I read this as Toyota Racist.
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
It can also very efficiently slip a belt/chain and become a brick, especially when starting quickly in a low "gear"
Yea. They’re great. My daughter is only her third one in a year and a half, and about to need a fourth
@@ck58npj72 nope?

Nothing is more reliable than a manual transmission. When they finally fail around 450,000 miles, you can fix it yourself in your garage with hand tools.
@@luqmanhakim64 it’s 100 percent true, it’s just common sense if you understand basic mechanics, also I’m not a boomer I’m 21, but I don’t live in America so drive manuals
@@louisbarningham Plenty of people in America drive manual. The reason GTIs, Golf Rs, & GT3s have been still made in manual for the past several years is BECAUSE of America.
Everything else you said, 💯
The flip side to the engine being able to be held at peak power throughout to deliver max speed but it can also hold the engine at peak efficiency throughout the gear to make fuel economy unmatched.
Best of both worlds.
"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.
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...
ust like how I got surprised when I go to know that kerosene is not only used in generators but also as a jet fuel, I got surprised when I got to know that the technology in my scooter's gearbox, once upon a time, got banned for making an F1 car in the 90s too fast...
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.
Even better: Toyota HSD: frictionless CVT via electromagnetic converters. 😉
And ingenious use of a planetary gear set (aka the “power split device”)
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.
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
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.
While yes it is theoretically faster, however after driving both for a good time I have to say that a dual clutch feels faster and is definitely more pleasant in the ear. The thing is that "shifting" in a CVT is usually slow. Want to overtake now? You should have to slammed the accelerator 2 seconds ago, now it's to late. A dual Clutch does, at least from a feeling, change the ratio faster. This is more important in situations that require quick desiciones. And it definitely feels and sounds better. Obviously my judgement could be wrong, but if I had to choose for having a fun time I would choose the dual clutch

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.
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.

@@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.

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.

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.
My favourite type of transmission is the CBT, which although it sounds very similar to CVT its works very different..
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.
They suck in Altima’s and Maximas lol
I blame people’s ignorance about maintaining their cars more than the transmission itself. Everything dies if not properly maintained.
We've had 3 different nissans with cvts in my family and none had any problems still going past 120k. I had a Ford Taurus and the transmission crapped out 100k. The "most reliable" car
That transmission is good... that engine is not lol
@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. Not even many car enthusiasts want to put up with frequent, complex or pricey maintenance routines for a few per cent of extra performance/efficiency.
@@LRM12o8 changing the transmission fluid every 30k is standard across the board. Everyone should be doing that. The only vehicle that I’ve seen that doesn’t care much about proper maintenance is a 90’s ford ranger. Get one of those if you don’t plan on maintaining your vehicle.
what he’s not telling you is cvt transmission wear out so much faster. as a mechanic i’ve seen some of these destroyed by 30-40 thousand miles’s
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. 😅
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
That’s the F1 problem tho, used to be the pinnacle of car technology but started banning any type of innovation.
I dont care if its good in F1 or not, a CVT on a day driver is a strange and unenjoyable experience..
Oh don't get me started on when it starts slipping my goodness
The best transmission ever on daily use. I do not have one, but my parents have subaru :)
Unless you live in a crowded city
driving CVT and gaining speed while losing revs is simply the most infuriating thing Ive ever experienced driving a car
People hate on cvt's so much and they don't even know why
It was so much fun driving my 2015 Lancer since it was one of those cars that didn’t have the “fake gears”. You can even shift it in low gear to rev and accelerate at the highest possible RPM (without needing to slam the gas pedal once you got it up to speed). Amazing thing. Sad it got totaled but was a fun car.
DCT: ☺️
CVT: 🫨
wait till slow traffic hit ya which most users use their cars on. enjoy the ultimate jerkiness 😂
A CVT-manual hybrid in series would be a great idea for peak power at all speeds.
Subarus basically perfected this. No droning or rubber band feel. Loving my forester cvt. Good mpg and reliable too
Totally agree my friend! Loving my Crosstrek!
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.
My murano has a CVT, which is extremely unreliable, but man is it fun to drive... I got the V6 and the first time I took it on a test drive, I was used to my 4cyl accord and I floored it getting on the highway. It put me back in the seat and took off. Apparently theres a switch when you floor it where it drops the ratio to give you acceleration at highway speeds. I was used to waiting 2-3 seconds before it really got going haha
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!
When I took auto mechanics in college in the 1980s my teacher talked about the CVT being introduced
What about the LST (Light Speed Transmission) on the Koenigsegg?
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
CVTs are alive in Scooters, as far as i know
My 2020 Corolla XSE has a CVT
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.
Yep, i had an 08 lancer with the CVT. Manually shifting was definitely slower than just letting it do its job
My wifes car is a kia with a cvt. Gets 35 mpg and is AWD. Thing has a surprising amount of power for such a little engine.
Beating the og pong with 5 counters with 3m is just peak brilliance on full display.
Unfortunately, CVTs do not seem to stand up in automotive use. Do any mecjanics recommend them?
None
In NFS Prostreet you can make a homemade CVT if you play manual + clutch and never let off the accelerator when upshifting lol
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.
I know they are the best but aren't they also much harder and more expensive to work on versus a manual?
"You cannot drive any faster than this" - shows a Nissan Altima 😂
It was actually a reliability issue that caused the FIA to ban it and also it was the performance advantage
What I hate about cvt’s is that if you put a loud exhaust it’s gonna sound terrible because it’s never actually changing gears
Also used in MTD lawn mowing equipment a real pain to change the belt
As long it is not a Nissan/Renault built one. You are good!!!!
Or they were banned because fragmentation grenades are not welcome on the race track
Imagine naming your event Formula One only to almost always ban the number one formula to winning.
I bought a Nissan Murano with a CVT and holy acceleration on that thing. It was similar to an electric car tbh
I have a 2017 Crosstrek so I can confirm😊
Thank you dork!
Now all we need is somebody to construct one for public use that doesn’t fall apart after about 36,000 miles!
This is why my Mondeo hybrid, with circa 190ps, can keep up with a Corsa VXR, E220D, Focus ST etc. the in gear acceleration is just brilliant. 60-70mpg and Oh, and I don’t have to plug it in.
I had a CVT in my ‘07 Altima 3.5. Sure it was quick- I loved that car. When those belts break, so does ur car as they are extremely expensive
Just imagine F1 with CVT with a v12. My ears would bleed.
It's not redlining at all times..lol
Snowmobiles use cvts and high horsepower sleds rip insanely hard. Go on TRC and watch some of those sleds run 0-160mph in the 3 second range, thanks to the CVT. (And turbos)
Got a kia seltos 24 ex have a cvt in it. And i never drove a hypersensitive car in my life. That thing will give the speed that you told it to have.
I heard “cvt” and knew there was gonna be an altima I got a 2015 myself and I knew it had to be in the video at some point bc it’s the only car that has a somewhat good cvt, been my daily for a while now I’m getting rid of it soon tho for a 2006 c5 or c6 corvette bc happiness to me means spending every paycheck I get for a beautiful gas guzzler❤️🔥
Sports disgust me because they ban things for being too good
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.
The more individual moving parts in force transfer system the less efficient the transfer. Also a belt will have some elasticity, soaking up power.
My Honda fit, cvt engine is a beauty.
