Dct vs cvt

I love my manual transmission in my Baleno. Way eco-friendly and cheap.

just gotta love his videos... very educational yet simple and fun

Thank you for the explanation. Do DCT’s have a clutch pedal to push? If I understand there is no clutch pedal with on the DCT. You would shift through the gears with paddles or a tap of the shifter forward / backward without pressing a clutch pedal... right?

Manual is better because is lighter

Manual easily. Hyundai's DCT is notorious for being clunky at times.

The mDCT was a 2500.00 option on my BMW M2 but the performance is so good that it's an excellent trade-off for me. I did a lot of shifting as a kid but now I want to waft along and take it easy.

I’ve always thought the Veloster was a neat design. Glad to see Hyundai “hot rod” it.

Curious how Hyundai duel clutch is compared to the PDK....

whiteboard = manual transmission, digital overlay = DCT

What a amazing video damn

I can’t imagine how much crank was the guy smoking when he invented the transmission? Lol

The power band of my 2004 VW TDI is from about 1,500 rpm to 2,500 rpm. It has a five speed manual transmission. Shifting at 2,200 rpm is common except for the 1 to 2 shift. I sometime skip a gear in light load conditions. I learned to drive on cars with three and four speed transmissions. An engine's power band is too narrow if more than five forward gears are needed

Gets to the heart of the matter at 8:33 . Tough choice for me. I've never owned an automatic and the only time I drive one is when I rent a car. Numbers are important to me although I've never come close to seeing the top speed of any car I've owned. I equate 140 lbs. lighter with being more nimble. On the other hand I'd like that 0-62mph in the 5's (with the DCT) and acceleration is a trait we see everyday. But the bottom line is fun isn't it? Yep, I think I'll pick engagement and fun over a half second faster to 62; manual transmission it is. Also since only 18% of Americans drive a manual it's a built in theft deterrent. Thanks guys.

Drive a regular Veloster since 2103 and love it. Gets excellent gas mileage and for the first few years I received a lot of positive comments about the styling, not so much any more as there are alot more on the road. It would be great if they made a AWD version of the N model.

How old are You Jason?

How do you service this yourself?

The best transmission is the coronavirus

Why would you ever need multiple final drive ratios for a single transmission? Why wouldn't they just pick one FD ratio, and then adjust the individual gear ratios accordingly to get the same effect?

I just hope buyers of the dct don't experience the same problems we manual drivers have with faulty transmissions. I own an i30n and Engaging 6th gear is a real game of luck sometimes. Still waiting for Hyundai to fix this issue. If the dct was available 1,5 years ago when I bought the car, I would surely have gone for that.

Automatic, newer BWM M models get an automatic for example

Jason, hope you get the opportunity to test drive the other upcoming N models. Not a fan of the Veloster and will be very interested in the Elantra & Kona N. I will have to admit halfway through your video I thought "hope there isn't a test". The slower less efficient manual transmission for me

With different final drive ratios, is there a difference in top speed?

my 6 speed in my mustang with 463 hp at the rear wheels and under 3000 lb no need for all the crap

ps if it has no clutch it is a crap city car for city boys

Manual is best as it not ran by a computer. computer suck in cars a real car has no computer and a real dash no fing tv screen on you dash no cell phone charger just a good real ride not all the new crap rides no fing cameras are needed and a real am fm radio with a real tape player as disks players suck the best tapes wear 8 tracks

Veloster is basically i30 right?

No, the Elantra gt is the equivalent of the i30.

My biggest worry is that in that momentary time where both clutches are engaged its causing them to slip some till one fully takes over, it is causing excessive wear. I have a DSG with 104k on it and wonder about it's life span.

Based on the footage (@ 0:30), the Autobahn drive was, if not illegal, then certainly impolite. There's nobody in the right lane being passed by you, so you should be in the right lane. Pretty inconsiderate behavior towards the guy who could be coming up behind you at 230mph in his Veyron!

Will BMW ever make manual cars again that are available in the USA?

How about cvt?

If I buy a project I’m getting a manual but I love the 7speed AT in my daily 370z.

2:20 I thought he actually put his foot on the board. 😂

Did get a dct kia stonic. Regreting it now. Manual next time again. Hate how it thinks it knows better than me wich gear to choose.

MANUAL for life homie

I stick with the traditional 5-speed manual transmission thanks. Anyone who knows cars know its best to keep it clean, simple & reliable.

Both have their advantages which have addressed. My personal input on advantage/disadvantage for a the dual clutch transmission, would be launch control (or consistent launches) and disadvantage 'car park manoeuvring' it takes time to get used to a dual clutch, there is a feeling of lack of control when not in direct control of the clutch itself, I find it difficult to find the sweet spot. They're not confidence inspiring when manoeuvring in tight places. Some real world track time comparisons would be great to see between these two (same but different) cars.

9:36 When was the last time you tried to bump start a car? If your battery is too low, you wont have enough to power up the ECM and pulse the injectors, so bump start wont work except in a very narrow range of conditions where you still have enough battery for the ECM, but not quite enough to start the engine.

Im confused why theres 2 different final drives for every other gear. Why wpuld you want 3.8 for 1st and 2nd (great for acceleration) and then 3rd and 4th is 2.7 (not as good for accel)???

most manuals are able to hold more power than stock which is a huge advantage when modding

Thank you again!! I finally understand DCT's. 😎👍

This was immensely infiormative and was great to watch. Could you possibly do a comparison between the 3 cylinder engines BMW is using on their mini coopers, new 1 series and in the BMW R8 and compare that to something comparative? Sublimely good engine for a 3 cylinder which is refined well but hardly talked about technically! would love to know about the transmission of the mini f56 models! thank you for the content

Well explained, but one major Disadvantage of the DCT is that it is controlled by a computer and the program it is running. Many DCTs will prevent upshift & downshift that will not cause redline and will automatically upshift & downshift when in manual 'M' mode (i.e., PDK), hence there is really no true manual mode at all. A manual gearbox doesn't have that problem.

Pretty terrible gas mileage for FWD. My GTI although slightly slower stock (not tuned) gets way better mpg.

Anybody else wondering why alternating gears operate on different final drive ratios? Logistics aside, I'd have thought it would make sense to have a more torque focused ratio for lower gears and less conversion and thus less loss in higher gears... Can anybody here explain the implementation in the Hyundai N-DCT ??

Best Car teacher ever Keep it up man

I love your explanation of the dual clutch transmission. It is immediately clear how it works. Great job of explaining a complex transmission in simple terms.

Perhaps you will analyze the process: a return bearing is inserted into the bicycle pedal axis (freewheel without backlash). In the working sector, the torque increases and the radius of the pedal is increased. It could be very interesting for everyone. Thanks.

If your car has 2 pedals, you are not a man.........lmao

Is it possible to have a clutch failure, where both clutches would be engaged at once? Sounds disastrous!

*I'm sorry but a hyundai isn't a real sports car* . They are like copy cat generic knock offs of BMWs MBs and other cars like they had a hyundai that looked just like a jaguar called the xjs300 instead of the jaguar xj300 they even had the same shitty reliability. Knock off cars. I drove a new one with a tiptronic knock off transmission and shifting from 2nd to 1st was so off that I nearly got rear ended because the ratio was so bad. Better to buy a used sports car then a new hyundai

Thank you to the companies that give people the choice of manual or DCT. I thoroughly enjoy my DCT car and will never own another manual transmission car. I drive my car in manual mode most the time, but when I don't even want to think about shifting, I let the car do it.

It just dawned on me why we all say "as you can see" on our automotive channels. Its all your fault Jason

I bought my Hyundai i40 1.7L turbo diesel 2016 with a DCT transmission in it. It has gone long at 190000km. Anyone know about the quality of the 7-speed DCT transmission from Hyundai? The only thing I've noticed so far is when the car is cold and I start driving. It's then feels rougher and like it slips. Wondering if an DCT transmission oil change would help it to feel a little smoother when it's cold started? Any hacks of getting the temperature up on the oil. Like haveing the gear selector in N(neutral) or P(park) for some time to warm it up faster before I drive away? It feels like it takes longer for it to get it to change into 2nd gear as well when cold. Otherwise with the 1.7L CRDi with DCT feels awesome when I accelerate it fast in the sport mode. I'm happy with it so far.

Three pedals and a shift lever. Anything else is blasphemy. More parts and electronic felgercarb = more things to break and more money to repair.

I personally find that highly boosted 4-cylinder engines feel terrible with a DCT. Without a torque converter to let the turbo spool up, you end up with clutch slip off-boost and massive lag. The shift time difference between even the best DCTs (Porsche PDK) and industry-standard torque converter automatics (ZF 8HP) is imperceptible in regular driving and I would take a torque converter over a DCT for a daily driver for reasons of better drivability, durability and lower maintenance.

Manual is more reliable, so it is the best.

Just one thing that i'm wondering is with the dual clutch transmission. When in first 1 and and 2 are meshed. then shifting only takes a clutch swap. but in second 2 and 3 are meshed. But does that mean that going from second to fist the synchroniser has to change from 3 to 1 first? and then swap the clutch resulting in a much slower down shift than upshift?

After having a zf-8 in my 2016 a6 that needed complete replacement around 30k miles at a cost of 12k billed to Audi cpo and then started to act up again two months later .... then wife’s 2016 s5 dual clutch started to act up I had enough of these complex transmissions. We do not beat on our cars at all. I went to a manual Tacoma and she to a model 3 performance. Either a manual or no transmission for me

Jason nailed it as always. I could actual follow along thanks to his meticulous drawings. Well done good man.

From my perspective the advantage of a manual is threefold. 1st is the ability to skip gears. I hate having to go through multiple actions to get to the gear I want. Which brings up the 2nd advantage, not having to "remember" whether I have made 2 downshifts or 3. The final advantage to me is a spin off of the second, I can tell which gear I am in just by the feel of where the gearshift is, I don't have to look at a readout to tell me thus not having my concentration interrupted at an inopportune time. It might be argued also that in a track enviorenment the "quicker" lap time may be offset with the possibility of being abke to stretch an extra lap out if the fuel or having a fractionally faster refuel time. Besides, they are more fun!

I have a single-speed zero-clutch transmission in my car 😉.

Eventually, there will be an autonomous vehicle that drives faster than a human with a DCT. Will that be better? No, because it's driver involvement, not lap times, that makes it better. There's a pleasure to driving a manual that is absent in the DCT, regardless of how fast it shifts.

where's the nurburgerking footage?

i have a 2020 sonata with the 1.6T (thanks to this channel) it also has a 7 speed DCT, love the package but slow city driving can be a little jolty from the transmission shifts, but that's what makes highway merging so fun. wish there was a sport mode and calm mode for the transmission

commercials are getting unmanageable - didn't make it past the manual trans explanation :(

Drawings are really top notch! As pedagogical it can get 😃👏

No transmission is the best transmission in 2020 🙃

Me trying to be faster than a dct shifting like a psycho

QUESTION- When the DCT is in 2nd gear (and 4th) does the lower gear shaft collar advance to the next gear up? Or is there a shift delay while both shaft collars shift together? If it's the former, it would seem that down shifting would be slower, if the latter, there would be a delay between each second shift. Thanks!

Ford’s dual clutch Powershit says hi

Manual of course

One quick question, I have a turbo charged petrol car. as per few details, its suggested to idle the car before starting and stopping the car especially after hard revv . But my car support "smart start/stop ( which off the engine when in a red light and gear is in neutral)". So will this feature work against that above mentioned "idling before stop" theory? Please reply. Thanks in advance

been in manual and been in dual clutch and manual is WAAAAAAAAAAY slower than dual clutch. Its painful the amount of time it takes a human to shift gears compared to computer that literally does things 1000s of times a second.

Great video!

I want my 13 minutes back too boring.

I don’t understand it.

Great video! Is it true that the Veloster n with the DCT is the only one that has the over boost feature?

The biggest difference is the cost to rebuild a manual gearbox vs a dual-clutch.

Manuals are old tech now. There's simply no practical use for them anymore. It's a niché market.

Outstanding presentation. I continue to be impressed by your ability to present complex topics clearly and quickly. Your drawings and overlaid animations in this presentation are excellent. Thanks for putting in so much time and effort on this.

Simple... If you want ride-rider connection, good adrenaline rush & want control over shifts go for stick shift. If you are lazy & want some adrenaline rush go for DCT

The diagrams are beautiful!!

Any chance you will REVIEW THE NEW TOYOTA MIRAI? Eagerly hoping (I hope they build a proper, realistic, efficient alternative fuel vehicle, so all the masses of r^e^t^a^r^d^s, 99,9% of humanity, get on it, fix the climate and leave combustion fuels only for those exclusive, few, true petrolheads' and riders' 0,00001%)

I assume no launch control in the 6sp? If it had it, that 0-60 time would be much closer. Additionally most oems would program their trans control to make it fairly useless in a track setting. Conservative Computer Blocked downshifts. How was the Hyundai?

Foe a performance or track car, DCT is the clear winner. For a normal road car, though, it is an inappropriate waste of money.

DCT!

When the clutch is disengaged for a long time it is not good for the clutch because it is weakening the springs which will cause extra ware on the disk. As I learned from a precious EE video. How is it different in case of a dct?

Would you please explain the specification found on 2-Stroke oil bottles like TCI and whatnot there is out there?

How does a dual clutch transmission compare to a quick shifting auto like the ZF8 in a straight line? Seems like the torque converter would have an advantage in launches thanks to brake boosting and torque multiplication.

Wait there's no power loss and a torque converter on a DCT so why the fuel consumption difference? Is it due to more aggressive lower gears?

Interesting question: I think its pretty complicated with a lot of factors, for example I have noticed that mor powerful cars often have BETTER consumption values given with DCTs or even automatic. The opposite mostly with smaller cars. Number of gears, setup of gear ratios, test cycles...

This man is the James Hoffman of cars

Brilliantly Explained 👌🏻

How does a DCT ensure that it shifts smoothly and instantaneously from one clutch pack to another? If a clutch pack were to lag behind because of a mechanical issue, would that smash the gears?

Huyndai got overheat problem : with dct in rush hour

@Engineering Explained Hi Jason, have a question not related to this video, but can't find a diffinitve answer. Hi there, quick question for you. I've always been taught that toe will even out, so even if you have one side that is badly aligned, and the other is good, the steering wheel will become crooked and there will be wear on both tires. I was wondering if this is true. it makes sense to me since that would provide the least resistance to forward motion of the vehicle. That basically all we really care about is total toe, and steering wheel straightness, as long as the tie rods are even remotely close in length. But I've been hearing that toe being excessive on one side can cause wear on only one tire, and it can only effect one side of the vehicle. If you have time to answer I'd be extremely grateful. I enjoy your videos a lot, for detail like I just mentioned that I normally don't get.

Yes DCT's are better in performance. What wasn't mentioned was the cost if it fails. I may be wrong but I think a MT will be cheaper to repair.

I can't believe you listed "bump start" as a pro for manual. Bottom of the barrel

I haven't watched the video yet, I do know DCT is better tho but I still only want manual

Hey thanks for information, would be wonderful if you explain the 18 speed manual transmission on semi trucks, and which is best: double clutch shifting of float between the gears without actually using the clutch. Thanks again
