@@aresivrc1800 most smaller tractors, mostly compact utility tractors have a Hydrostatic transmission. Hydrostatic Transmissions are like a CVT transmission, but it has the hydraulic pumps, power take-off, and 3 point hitch all in one package
@@yacinealg152 most tractors use a hydraulic valve and pump to change the gear ratio by applying variable pressure to the ring gear on a planetary gear set. That way there is no belt or chain. Here is the link to a video that explains it. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dgtIKMAjvFI.html
I'm sure you could build a CVT strong enough to two 2-tons... for a few minutes. It doesn't have to last hundreds of thousands of miles, it just has to last to the top of the hill.
Yeah look. Mate's 2008(I think, maybe a little older or newer) lancer shot it's gearbox towing a 500(ish)kg trailer with about 100kgs of crap for the dump. So close to 600kg or around that. Since doing a manual conversion he'd has no dramas with that exact same trailer even with more in it. CVT suck ass. In saying that I doubt they ever expected someone with a Nanna spec lancer to be towing so they probably didn't build a gearbox for such applications. Nonetheless still hate CVT. 😋
a CVT has many benefits people dont realise, beyond the "quicker" shifts because it has constant ratios. You can design your engine to run best at 1 specific RPM, like a 2 stroke powerband or where your turbo makes the most torque, and set up your CVT accordingly. In the real world, we just don't have heavy duty CVTs in the mainstream yet.
I drive a CVT accord (2.4, 2017) and I get like 20-25mpg city driving (usually more aggressive on the throttle) but I get upwards of 40mpg crusing at 80-90mph
Manual at least in my opinion is still the best combination in all ellements plus you get to select speed and torque output and is a completely locked system as long as the clutch is operating normally
CVT is just crap compared to things like tcfa or dct. 92 williams used cvt in a time when all the others were 3 pedal manuals, hence the reason why it was good
You found something BeamNG doesn't simulate fully: CVT friction and slip! But for real, I think Beam only simulates some of the friction loss properties of CVTs, I don't think it simulates the possibility of slip at all
This can all be added to the simulation in later stages tho It's really hard to stimulate this correctly because they're are so many variables involved Centrifugal and centripetal forces, material density, stretch, friction, heat coefficient.. Even more than I thought at first 😂😂
@@williamchristian3489 I don't think so Since CVT are common for heavy trackor It depends on how the manufacturer designed it to be. It's not like the CVT on the Subaru XV can handle these. Get rid of old school mind set
@@MDCYF Of course. Historically speaking, CVTs have been relatively unreliable however. Look up complaints and recalls of Jatco CVTs. It’s clear a big majority aren’t those super tractor CVTs that maybe they should be? I’m sure there’s pros and cons to either design.
cvts are probably the best transmission but they have no money or time backing them unlike the more traditional ones. if you could somehow make a chain or more sturdy belt im sure they would be good for hauling
Of course in any simulated environment like this, a CVT would definitely win. Although in the real world CVTs would break easily with this kind of load
There is one thing manual transmissions will always have; Reliability. Not that automatics or CVTs can’t be reliable either. But manuals are inherently more reliable because they’re mechanically much more simple.
@@ricardorafael2015 very true. I drive a truck and they are almost all automatics now. They never miss, but they do make very stupid shifting choices sometimes.
If you have 100 HP or less, the CVT rules. Start adding power, and it stops being so nice. The thing is, you can optimize that engine to be very efficient while giving those 100HP. Also, keeping the rpm below peak power was completely arbitrary, it could have been set to 5.500 rpm and given better results.
Agreed completely. As others have mentioned, the stuff that's used in tractors is usually decent. But what's in civilian/consumer-grade products is nowhere near the same thing. I have a 1996 F-150 with a 5-speed and I have run the snot out of that thing. Literally the only thing you could do to destroy that transmission is shift it into reverse going down the highway.
That also means that it was using the engine to the least potential. The fact that the others overheated shows that engine was more fully being utilized because more fuel was being burned, more power was being made, and therefore more heat.
@@Tracert-mc1hu the least potential?? makes no sense. Both automatics have torque converters which makes them loose physical energy because of the transfer in energy. Manual is a direct connection because of the clutch so actually the automatics make the engines work harder than the manuals do. This is also why manuals get better gas milage than traditional torque converted automatics.
@@garretrocha8 Not with lockup torque converters, no. And a CVT is, theoretically, the best transmission because it keeps the engine at its optimal rpm instead of preset ratios.
@@Tracert-mc1hu I disagree. I think it's in a more sustainable power band. The automatic and CVT were trying to get the highest speed at the lowest RPM, and when you're going up a really steep hill, that puts an enormous load on the engine. Essentially, those transmissions are disregarding the limits of the engine in favor of low rpm and speed.
The engine overheated from being run at max output for several minutes straight at low speeds meaning little airflow into the radiator. At highways speeds it wouldn't have been an issue.
No they are actually pretty good and even got lowest laptimes in F1 and was banned as it was too good if enough R and D is put into it it will get pretty good
Unfortunately, they're efficient on paper, but the ones that are generally used have such a massive tendency to fail that the repairs makes them not worth the trouble to most.
Love the way this game accurately depicts parasitic loss between the three transmissions. It's accurate that a CVT saps the most power from the engine.
people usually forget that. That's why if modern manuals had the same top gear ratios as current autos, they'd still get better fuel economy. That's the only reason the autos have higher epa economy. They get proper gearing, most manuals (4 cyls) are around 3k at 70, while the autos are usually now only at 2k.
@@aresivrc1800 can you adjust where it keeps the RPMs? Seems like I’m the top speed test it’d perform much better if it hovered around 5800 RPM instead of 5000.
@@BeesonsCars you can only change the size of the torque converter, which then affects the peak rpm before final ratio is reached and it goes back to rpm acceleration. Larger converter would bring the rpm down and qouls increase low end launch, smaller would increase rpm but reduce torque efficiency and acceleration.
God I wish we had CVTs that could handle this much power and abuse. I love the benefits of the. CVT, the issue is they aren’t good for high load applications like SUVs and trucks, not yet at least.
@@NFLYoungBoy223 The Murano is a small SUV, same class as the RAV4. That’s barely heavy considering plenty of sedans weight about as much. That’s not much stress to the CVT, compared to what it’d experience in more normal sized SUVS, or especially trucks. And certainly not from Nissan.
@@po.russki And even though their CVTs are mainly traditional (especially for the asian market), they actually have the tech to allow you to put a Subaru with a CVT in low gear so you can get up a hill easily or get power quickly. These things are great tbh.
With the high cost of repair/maintenance/replacement of automatics and CVT I’d go manual if I had a choice. I have had autos in my last 5 vehicles only because manuals are so hard to find Cheers
i'm actually sweating nervously for the CVT torque power because you know, belts and stuff. but it actually stuns me that the CVT came out on top i think the main problems with modern cvt transmissions is that they attempted to mimic the automatic transmissions computerized hydraulic shifting which produces more friction and heat thus making the transmission vulnerable to breaking down.
I built a CVT T-Series and swapped in the 4cylinder diesel bus engine to make a more “city run-about” truck and it works fantastic. If only CVTs could actually handle 1600lbft lol
Wasn‘T entirely fair because the auto lost speed at the top due to wheelspin and the diff wasn‘t locked, while it was when the manual set the benchmark
This is good . CVT's power delivery is way efficient because it remains in the constant rpm range so the vehicle can stay in the optimum powerband as long as it wants according to the needs . This is one of the benefits that many of us people didn't realise .
@@Odin3v E-CVT is the way to go, no belts, no pulleys. Just an engine on one side and an electric motor on opposite side of a differential. Very efficient and very reliable!
@@robsterandkadubb yep, If someone built a hybrid pickup with power in mind instead of mileage they could use one of those to get tesla-like performance out of a gas engine
No people are stupid and do not know hoe to use a cvt . I have a Friends with a Volvo cvt with 500k on te meter (KLM Europa) (not miles) Car still runs with no problems. My own Honda cr-v have 200k klm on IT . A cvt you have to replace the oil on time . And if you do have tork set a extra oil cooler on IT.
Your launch with the manual one at 5:10 was total crap though. Dropped from 6k to 2k RPM. And I do really wonder if you geared these trucks correctly, also keep in mind the automatic is a 4 speed. Were it a 6 speed, maybe the manual would’ve beaten.
@@conwaysdetailing387 It’s horrible, the RPMs fell almost to idle. I wonder if just flooring it from the standstill and letting the game control the clutch makes a better launch, very likely yes
@@conwaysdetailing387 manual did great, but imagine if the auto was a 6 speed? Either way, true comparisons aren’t really possible IRL either, just take a look at the Quattroporte M139: The automated manual (DuoSelect) one has MUCH better gearing than the Automatica models (I have ratios from both models if you’re wondering), even though both are 6 speed. So, the Duo obviously wins any performance comparison you want. It’s even got a dry sump.
@@satsumagt5284 a 6 speed auto highly refined and tuned would have done great. As far as letting the game run the clutch so that it would slip some, it wouldnt help anything, you'd just have it slipping the clutch and not going anywhere rather than dumping it and grabbing the next gear and getting rolling
To this day it amazes me that despite CVT being less sophisticated than a 6 speed automatic, it still somehow just doesn’t perform as good as a standard automatic when it comes to maintaining a gear ratio.
CVTs don´t maintain gear ratios, they can, but then the efficiency is lost. Cvts constantly change year ratios, to keep the engine stuck on the rpms where the engine gives the maximum torque and power.
The fact that the Auto had 4 gears and the Manual had 5 is a clear issue with the comparison…or at least it might have been better to make sure the gearing was the same
It is best to drive a trailer with an automatic transmission with a torque converter. A torque converter is wear-free thanks to the oil and there is no interruption in tractive power. When coupling manual transmissions, the clutch linings can quickly burn under high loads and there is also an interruption in tractive power when shifting.
Did the CVT really win the uphill tow? Cause to me if the vehicle is smoking and the engine is flashing that usually means something went wrong. I feel the manual won that one since it wasnt even smoking by the time it reached the top
In Puerto Rico CVT is called the unbreakable, if you change the oil transmission when CVT needed you will have a transmission forever, but if you change after 65,000 those 5,000 will cause big damage
My mom with her old Fit/Jazz CVT beat all kind of cars on the traffic lights it's amazing. It's funny how people hate on it because all them got their asses beaten by CVT, also that transmission is so damn good to do fuel economy, also the comfort is amazing the car feels smoooth. My mom had 2 Fit's (amazing reliable car) all them she drove more than 200.000 KM without a problem on the transmission it's not bad like people is saying it’s just sour grapes. Just do the oil change in the right time and everything will be fine.
Time to try a Lenco! And just for craps, a Torqueflite with 3.08 gears but a 3,000rpm stall, exactly like my buddy David did in high school with his old Impala with a 327. Completely ass-backwards mod to make with the ridiculous freeway gearing, and people always stared at any speed because it had empty Cherrybomb mufflers that were stupidloud.
None of those transmissions exist in BeamNG.Drive. It's only various generic names for automatics, manuals, and cvts. "Race 6 Speed manual, drag automatic, etc."
Cvt more expensive when it fails I was told, and you won't find them with high mileage like some automatics 200k, some manuals have gone for 500k + just 500ish clutch replacements, so distance per dollar, msnual, then automatic, then cvt, from what I've been informed
efficiency was definitely not factored in a manual gearbox is always the most efficient and a cvt aswell as a torque converter automatic are not very efficient at all
To be clear, most automotive CVTs break because they are cheaply made. The biggest reason economy cars use CVTs rather than something like a 10spd auto is because the CVT is way cheaper to build. The 10spd is just as capable as the CVT of keeping the econobox engine in it’s efficiency range, but the CVT is way less expensive. If a manufacturer actually put some money into building a good quality CVT, it could be built to handle any torque or load you wanted it to. Saying that a CVT would explode under this load just because you saw CVT from a Sentra fail is like saying that the auto trans from a Ford Escape would explode if you tried to tow 10klbs. Of course it would, but an auto trans that is built for that kind of load would be fine. Same with a CVT built for that kind of load.
I don't like CVTs or single gear transmissions because they don't shift gears. I like conventional, multi-gear transmissions more because I can hear and feel the shifts
CVTs in real life give up and shut off to protect from damage. While autos will keep climbing with or without low gear due to torque converter, and manuals, well more predictable, and usually would have low range for climbing.
Man you understand a lot about beamng mechanics, how do I put the ETK-K series with 1000 horsepower? And how do I get fire out of the exhaust type a GTR?
Too bad in real life, the CVT destroys itself in cars at a much higher rate than the manuals and automatics combined. Maybe in 10 years or so, the durability might get there if the reputation doesn't destroy it completely before then.
I think this was more a test of the clutch since manuals, sequentials, and DCTs use a dry clutch, automatics use a torque converter, and the CVT is kinda its own clutch as far as I know.
is there any difference about the CVT and the conventional automatic transmission bc i have been researching about the CVT on google but i have been only hitting my head against the wall so can someone please explain to me about the difference
It’s. A bit tough to explain, but CVT’s use belts on moveable pulleys as opposed to physical gears. The CVT can move the belt pulleys in any configuration to essentially create one gear that can change into different, endless gear ratios. Normal transmissions are physically switching gears and have a limited amount of gears to run through.
@@TechTubeHDReviews i think i understand but still correct me if i'm wrong the CVT is just a gearbox that has inside of it 2 gears that are connected one to another by a belt and semi connected to the engine but the higher the rpm of the engine the faster the gear that transmits power to the wheels becomes
@@veljkostejic9594 essentially, but there’s no gears. Just pulleys and belts. The pulley is able to move inward and outward, which pinches the belt, moving it closer or farther away from the other pulley, effectively changing the diameter of the pulley. This is the best visual representation I could find: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-uCEvBGT8twM.html
This is a good theory test. However, a CVT is best for commuting and regular driving. An Automatic is best for new drivers and racing. A manual is best for fun and experienced drivers.
