Just curious, why didn't Nissan use CVT on Z?
 

When looking at Nissan's lineup, almost every car uses CVT now (I'm talking automatic version of course). CVT basically eliminates gear shifting and produces smoother and more continuous power output. So why did Nissan opt to go with 7-speed auto on the Z instead of CVT? Is it just for the pleasure of the auto owners to still be able to enjoy shifting and more control in gearbox? Or is the CVT gearbox not able to handle the HP and torque?

Z is a sports car!

I wonder if the CVT can handle 7500+ rpm? My mom has a '06 Murano and that's got the older VQ35DE that revs to 6600 rpm. Similar torque to the 3.7L we all have but slightly less HP.

just thinkin' outloud...

Well, CVT can get rid of the gear shift lag. Theoretically, the car should be able to go faster with CVT.

back 3-4ys ago 7sp AT with rev match was still considered kinda new.

:iagree:

Plus in sure that CVT would be too smooth for a sporty car like the Z, some jerkiness is still needed IMO

CVT can't handle very much power, the centrifugal force would tear it apart

Murano has a lot of power as well.

No way,CVT dulls the driving,the best now is use DSG...

True. Perhaps the next generation Z will have the duel-clutch system. Personally, I would still take the traditional manual tranny over any other kinds.

Yeah, that shiz is slick. :driving:

cvt's feel just terrible to drive. make the driving experience/sound completely uncomfortable to people not used to it and ruins any connection of car with driver

dsg's are overrated. go drive an r32 golf and u will see why.

the z 7 speeds is prolly one of the best auto's on the market

GT-R use duel clutch system

The CVT is just fine for my 2.5 Altima, but I would not want one in my Z. It is really a disconnected driving experience.

Although, I do wonder at times why the little 2.5 Altima engine does just fine on the highway at 75 MPH barely turning 2,000 RPMs, while the Z is closer to 2,500 RPMs. With the extra power of the 370 it would have been nice for that extra gear in the AT to be more of an overdrive for better mileage.

My question is not about CVT but why make a sports car with an auto at all? :stirthepot:

ALL of that plus CVT uses a rubber band as main part for shifting-not good for high H.P.

you guys are making me not want to buy # (3) per mr.alcheng's recommendation. :ugh2:

No worry Mr.kenchan.... go for (3) since it is not a Z... ;)



To the OP, think about "Why does the Z need a CVT??"

Now you know why doesn't the Z have a CVT???

Think deeply....

:tiphat:

I have a friend who is a tech at the dealership. He replaced a bunch of CVTs. Everytime I go there for a visit they're replacing CVTs. It doesn't seem to have a good track record.

:tup:


:ugh2:


:wtf2:

How many people are tracking CVTs? :icon14:

hopefully nobody

You mean to tell me no one replaces 'normal' Auto Tranny's? Nobody experiences Auto tranny failures on any other vehicle?

Here is my track record: I have an 08 Altima with the CVT. I love the smooth quite non-bumpy ride when I am just taking a "family" ride somewhere, or stuck driving in heavy traffic. If you've never experienced a CVT going up a steep upgrade with no shifting, abrupt bucking, and gear hunting, then you don't know the CVT's merits.

And, since I don't abuse it, I've not had to do anything on it but change the fluid at the regular maintenance intervals.

I also have an '05 Titan, and its the 'normal' auto tranny. I have had no issues with it either, and it is fun to drive too.

..and last but not least, I bought my 370Z with a manual tranny for the sportiness and the thrill. Each vehicle has its own prupose and mission, and I love driving them all.

the simple answer is that nissan's CVT transmission is made for FWD applications (altima, maxima, quest, etc) and the 7spd auto was made for the RWD based applications (370z, G37 coupe and sedan, M sedan, etc). also, i'm sure the torque rating of the CVT is much lower than a traditional automatic that's had time to evolve and become robust. the CVT actually makes a lot of sense in a FWD application since the packaging of it is, i believe, quite a bit smaller than a traditional automatic, especially a 6 or more speed auto.

:iagree: ... Good Answer...

My 6MT Z cruise at 80 mph around 3000 rpm. The engines are different. VQ is a much higher rev engine than the 2.5 Altima one.

Second that!!:tup:

:bowrofl:

I had the Altima as a loaner for a day. It's not a bad car, but the engine drone with the CVT is just awkward. It's not a deal breaker, just awkward sounding haha.

No drone in my Altima. Quite as a bird (non-chirping kind...)!

But, just to get back to the subject at hand - CVT is for front wheel drive vehicles. You find it in the Maxima and the Altima but not in the Rear Wheel Drive Nissans, to include the Z. I think the best explanation given is by HKYStormFront a few posts above this post...

CVT cost Nissan my money towards a maxima....

I guess it's kinda judgement call. A friend of mine owns an Altima and he loves it. He told me the acceleration is so smooth (ok...certainly not as fast as Z), and you won't feel the gear-shifting hump like regular auto.

where would the paddle shifter's go.............................

my wife's rouge has it imho it a toy.......

not hijacking thread but i'll never by a front wheel drive anything

Paddle shifter goes along w/ semi-auto and duel-clutch system. With CVT, there should be no paddle shifter since there's literally no gear to shift! Those with DSG or dual-clutch system such as GT-R have paddle shifter. Standard and out-of-date automatic cars do not have paddle shifter

sport package equipped nissan's with CVT have paddle shifters and a "sport" mode for the transmission that "shifts" to designated ratios to simulate a 6 spd automatic. by no means does that statement mean that it actually works, i'm just saying it's there lol

hmm...I certainly did not know that. It's weird tho since CVT literally has no definitely set gear. How is it supposed to "shift"?

it just slides to another pre-set ratio as quickly as it can. it's not very convincing as far as i've heard

It's not, at least not in my Altima. The first three "gears" do not really seem to change much of anything when you shift through them. Shifting into "fifth" and "sixth" do drop the RPMs a bit. It does seem to be really more of a gimmick than actually something useful. But, as a 4-cyl DD, it works just fine to drop down to "D" and leave it there.

Cvt is horrible. Try merging into traffic quickly with it. You press the gas and wait at least 2-3 seconds before any real acceleration comes on.. Scary if someone is coming up on your ***..
Also my track record with cvt's is not so good. Had trans replaced both in my Murano and my Cube... Why do you think Nissan bumped up the CVT warranty to 120k miles?
