I am looking at a few Nissan vehicles and most of them are CVT transmission, how does the drive feel compare to regular automatic transmission cars?

In short, what is CVT transmission ?

In the long term, will maintenance costs be higher or lower with a CVT vehicle compared to a regular automatic transmission?

Thanks in advance !!

*CVT noob here :okay:

CVT, you can imagine as an upgraded version of your sewing machine "gearbox". The "gears" are done by varying the diameters of the pulleys. In the basic modem, the car will sound like a sewing machine, because that's how it is supposed to be. The engine will be at constant rev all the time once you stop accelerating. However some manufacturers have put in a few programs that will make it sound more normal.

CVT gearbox is meant to be self contained, maintenance should be higher than regular automatic because you are supposed to replace it as a whole unit. Remember Japanese manufacturers assume during the service life of the vehicle, you take it to an authorized dealer instead to an indy dealer; so generally they don't publish detailed repair informations like their European counterparts.

Automatics are not as efficient as CVT (heavier, more friction surfaces and more complex). CVT is more lighter and gas efficient, that's why they are big in Japan where gas is expensive. However automatics can usually handle more torque and are easier to service.

CVT is most useful in Hybrids because the electric engine gives constant torque, not to mention for hybrid fuel efficiency is the bragging rights.

If it is a low powered car sub 150hp, even less torque. It doesn't matter, but it is something I suggest to buy only new.

Nissan offers 10 year/200,000km's warranty on their CVT's (for pre-2010 models *credit to tofu*)

Also when u test drive a CVT equipped vehicle make sure you drive it at low speeds in residential streets without giving it a lot of throttle. The one I have driven vibrated at low speeds up until a certain RPM, until the Torque Convertor disengaged or something.

Also many like to keep the RPM's low and tend to shift to higher "gears" sooner and may experience lugging or lurching, kind of like driving in sixth gear at low speeds on a manual

The engine stays at the same Rev and accelerates but drones. Weird as Fuck when I first drove one

200k kms only on the pre 2010's :P

they're different and would feel weird for some. CVT technology has came a long way since they were introduced into the earlier 2000s Nissans.

They are quite smooth (shiftless) and adjusts really quickly to scenarios (dont have to downshift lag like a regular transmission does). It makes the powerband of the car more flexible. Has somewhat of a rubber band feel with revs.

There are a few things that do annoy me though since I drive those cars everyday:

- noise. Some lower end models are noisy as hell, especially with a 4 cylinder motor. Higher end V6 models are much better. The noises it generates along with the thrashy 4 cylinders sound very uninspiring.
- Strength. They cant tow as much as a conventional transmission.. and constant towing w/ lack of servicing would kill the transmission. They have improved on the design of a new gen of CVT on the 13'+ Pathfinder, made it lighter, stronger and added an oil cooler... not sure if it'll last too long though.


Just a few things. More and more manufacturers are moving into CVT tech for the line up. Even the Accord has it now on their 4cyl models. A matter of time when most entry level cars will have it!

Feel free to PM me if you have any questions regarding to the Nissans you're looking at!

Since CVT have "infinite' gears so to speak, some manufactures have "sport mode" for cvt's where you can shift preset gears. They kinda work like a manual gearbox but without the significant drop in rpms. On my RVR and Lancer, it's kinda fun to play around with, but you won't get optimal mileage; leaving it in D should net you higher mileage.

When you're off the accelerator, there is a noticeable amount of engine braking like what Ruthless said.

wut??

CVTs have been around in cars since the 20s. Available in US cars since the 80s at least.

If you've ever driven a snowmobile, you'll know what a CVT feels like, as they've used CVTs almost since the inception of the machine. A lot of ATVs use them too. My dad has an old (early-60s, I think) Shopsmith Mark V (http://www.shopsmith.com/) that also uses a CVT to let you dial precise speeds for different tool attachments.

We have one in our 2008 Patriot. I wouldn't say it's particularly good or bad, better or worse than a standard automatic... just very different than what you're used to. A lot of people don't like them for that reason alone.

In cars, maybe... they've been around far longer than that in other modes of transportation.

[Jmac]

All the CVTs I've driven gave me new appreciation for automatics ... and I hate automatics ...

Didn't care for the Prius at all, didn't care for the Sentra, the Cube, or the Versa in CVT. Ended up convincing my GF to suck it up and drive with a manual gearbox. Couldn't be happier.

Nissan didnt have them in the US till early 2000s

[dared3vil0]

Sorry man, but the automotive world doesn't revolve around Nissan's


:badpokerface:

:troll:

[predom]

you buy a CVT when all the fun is gone from your life, and you just want something to get you to the cemetery.

[tofu1413]

OP is asking about CVTs... and hes looking at Nissans.


The car world would be a bit different without that brand though...

No Z. No GTR. No Timpo.

[dared3vil0]

^ I would buy an Altima/Maxima 3.5 SV tomorrow if it has a normal auto or a manual. CVT's just plain suck.

[tru_blue]

thanks for all the replies !!

So what are some positive things and negative things about CVT cars in general then ?

[dared3vil0]

^ If you're still asking about positives and negatives, i'd suggest actually reading some fo the posts people made...

I had an '08 Patriot. Test drove a CVT but really didn't like it, purchased a standard 5-speed instead.

Definitely something you have to try out to see the difference. Maybe I'd have gotten used to it eventually, but I had a preference for standard from the get go.

[Zordon]

I have a 11' Cube and i'm still trying to get use to the CVT. On a 4 cyclinder, it is super frustrating if you want to go fast (loud like a scooter)... so now i drive like a granny. The droning, the clutch slipping feeling when it is adjusting to the gas input, whining noises when it is coming to a stop and did i mention the droning??

[NKC ONE]

Loved it on my Murano 2.5. Smooth power delivery and great gas mileage. I guess it really depends what purpose the car is for. If you value sporty then CVT is not your friend.

[Splinter]

CVTs are great in theory, a big part of the efficiency loss in cars is because the engine constantly has to change speed to match the vehicle speed. With a CVT the engine can stay in its most efficient spot and the transmission makes the adjustments as necessary.

It doesn't make for a good drivers car is all. It's not 'fun'.

Gotta say, I would have preferred a standard over an automatic of any kind... but it's more the wife's vehicle, so...

I think this is a big part of the hate on CVTs... with modern ones especially, you have to understand that the computer is controlling the transmission AND engine for best overall efficiency (not JUST fuel economy), so if you mash down the pedal and the computer thinks, "Hmm, that's not really going to help matters", then you won't get the response you're expecting. I've found the Riot actually accelerates better if I roll on the gas gradually and steadily, rather than just flooring it, and while you don't get that instant kick-in-the-pants you're used to with a regular automatic, you find you're up to speed before you know it, almost without noticing the increase.

Not so much for a "driver's car" for sure... but great for a commuter or daily driver.

[Szeto]

i got a '10 altima and i don't mind the CVT, no vibration at low speed. Also, I believe the extended warranty on CVT applies to the 2010 model. '11+ models received updated CVT and 2013 models has the next generation (?) CVT but from what i see on club forum many '13 owners are having issues.

you should test drive one both in city and on the highway, you'll probably find the vehicle accelerates better in manual mode

[mos_skeeto]

Owned a Lancer for 4 years with a CVT.

Pros:
- Comfort. Passengers often comment on the ride comfort but not sure why until I tell them the car doesn't shift.
- The Mitsu shifttronic mode is more engaging than some automatic shifttronics I've driven. For one it actually sticks to the gear you're on unlike my current Toyota which kinda does what it wants and uses your shift number as a recommendation. The shifting is only for fun as the car is faster in auto-mode.
- I guess it saves gas but I really don't notice it

Cons:
- It's slow from a dead stop. It almost feels like you're starting in gear 2 to be honest. However once you're rolling it's quite peppy especially in the 20-80 range since it doesn't shift.
- It's not too bad for city driving or lower mainland highways. I hated it for long drives in the interior and made me miss the sound of gears. My current car has a 6 speed auto (no dual clutch) and I prefer it in every way over the cvt (minus the shiftronic which I rarely use).
- Noise... it does sound like a sowing machine.
- Easier to pass the speed limit because it can slowly creep up in speed without you noticing (very minor issue)
- For the Mitsu it cannot take any more horsepower so power gains are a no-no. I read on a forum where they added forced induction and the transmission started to fall apart.

In summary: fine for an eco car, doing city driving. If you're a performance car enthusiast or like to zoom around, might want to look at a manual. Given the choice I would pick a non-cvt automatic over a cvt.

So the bottom line is if you want both fun and efficient then wait for the Double Clutch systems to be more common! (DSG/DCT/PDK/ecoshift)

[Volvoman]

I hate it.

I had it for 4 years in my Nissan Versa. It shakes when accelerating from a stop. Slow, especially when you're on the highway and need to overtake someone, feels like you're trying to accelerate one gear too high. Maybe it would be better in a car with a bigger engine, but in a slow car, it makes it even worse to drive.

[!Yaminashi]

My car has CVT. The only negative for me is that like others have said is it's slow from a dead stop.

After that initial "shift" or whatever the hell it's doing, the drive is fine

If you're one of those "only real men drive manual" rednecks, then stay away

[dark0821]

i DD a 2012 rogue with the 2.5 inline 4 with CVT on a 3500LB chassis...

you know what I didnt mind it at all, and for a CUV, you were not going to win races anyways, if you just drive it like a normal car, I wouldnt say its worse than an automatic...

[godwin]

Double clutch is a lot heavier and has more frictional surfaces than a CVT (not to mention expensive). It needs a lot more sensors and processing power to keep track of the gears in order to shift.

You basically have to pick extreme fuel efficiency ie CVT or fun and/or torque.

Just because the word is hip and sounds a lot since it has "double" on it.. doesn't mean it is good in every situation.

If it is a grocery getter or commuter who see a car as a appliance, CVT is the cheapest way to go.

Redneck means car enthusiast now?

[hk20000]

specifically for a 2010 Nissan Cube with a CVT, if you just had an emergency stop from say 50km/h you are UNABLE to accelerate again without stepping on the throttle with a lot of authority.

The abrupt stop will confuse the gearbox momentarily, and then it will try to resume after lining up all the sensors and pick a usable ratio.

Something you will need to adjust to.

[vantrip]

One thing for sure on the cvt's is that it is quite odd and if your used to regular transmission it will take some time getting use to. Drove the companies sentra for the first time and thought something was wrong with it, until I realized it was ctv. I still find it funny every time I drive it.

[!Yaminashi]

Redneck means car enthusiast now?

What I mean is there are some "car enthusiasts" on these forums that criticize anyone and everyone that drives something other than a manual transmission and think that if you dont, you dont have the right to call yourself a car enthusiast. I'm not gonna get into it but there have been a few threads like this in the past.

No one will deny that dual clutch, automated, manual transmissions shift faster. The argument is that many find conventional, manual transmissions more fun.

[!Yaminashi]

Not arguing that. What I'm saying is that I think its a problem when someone thinks they have the right to say others aren't real "car enthusiasts" based on the transmission in their vehicle.

To each his own. If everyone liked the same stuff, it'd be pretty boring.
