Exactly right, the Subaru driver next to me at the light just saw the Red Bull fly without any jerking. I must admit that you gotta keep a close eye on the speed as it shoots to 110kms/hour in no time and you can't even feel it because of the quiet cabin
Am taking it easy for the first 1000kms anyway.....OR TRYING to

Re: X-Trail T31 - CVT transmission Hi Jalal,
I was wondering when you might get around to making a post on the operation of the CVT. There are some really good posts on this subject in the T31 Petrol (CVT) part of the forum. I found that as I got closer to the 10,000, the tacho going up to 3000 rpm didn't seem to be as noticeable. If you are first off the lights and you can apply the amount of accelerator you like, you look around convinced that you would never drive anything else. However if like me, at the next set of lights and your buried 3rd or 4th in the line and you need to follow in the que, or as another post put it, 'Driving like Miss Daisy', this changes. When only able to use a small amount accelerator, it tends to change up way too early and the engine seems to labour. As mentioned elsewhere, a quick flick into manual mode is the go as Manual mode always selects a gear 1 less than its present ratio. Still, I don't like any engine labouring that way. A bit more accelerator will finally get it to kick down a gear or two but by now the gap in front of you is large enough for a semi trailer to pull into. Once you become aware of the driving style needed, it is a great thing to drive. Strangely if you went to the service department with your manual Xtrail and told them that when you try and accelerate from 20 klm an hour in 5th or 6th, the thing spits at you, they will tell you to shift to a lower gear before accelerating. Take you CVT powered unit and explain the same scenario, they say it is the CVT doing it's job. Go figure.
Regards for now
John

Re: X-Trail T31 - CVT transmission Hi John,
I haven't tried the manual mode yet, so I will report back as soon as I do. I do notice the engine labouring at hard acceleration but what I do now is lift my foot off the pedal and press again, which is similar to what I was doing with the T30 auto, it seems the CVT increases speed more steadily this way and the engine is not labouring as hard. I have to take into account that the car is only 200kms old, so things are still getting lubricated and settling inside the car at this stage.

Geez Jalal, only 200kms, I think I clocked up close to 800 in the first 3 days.

Re: Hey guys,
CVT definitely takes a different driving style.

i suspect that like other auto/dgs(vw)/cvt and alike style boxes, the x-trail gear box is mapped to achieve the best fuel economy it can by staying in the highest gear/lowest revs possible. i would say that Nissan have done extensive testing to make sure that while doing this the engine has enough torque to stop any damage but they throw in the manual option so if you feel it needs a kick along you can flip to M and as you said it changes down to a lower ratio because it is assuming you have put it in manual to achieve a bit more power on the spot.
I drive it in manual now and then just to take the engine through the rev range as when it is in D it usually doesn't go above 3500-4000rpm esp when the wife is driving it
i love the smoothness of the CVT but I'm glad there is the M option for the above reason and cause sometimes i just like the feeling powering through the gears

Well yeah mate, am not the main driver of the exy as you know and my wife doesn't need to drive that far, so I reckon the Red Bull will be a super low kms car

Re: I have the same problem, bought the Exy to replace my work Pajero, now I get to drive the wifes Corolla during the week. As for the CVT manual mode, I mainly use it for extra engine braking in the hills, seems to work fine for normal acceleration and even towing. Looking forward to finally clocking up some miles at the end of the month, Adelaide, Townsville, Brisbane, Sydney, Canberra back to Adelaide.

Re: Well we must be more relaxed here in Newcastle, when accelerating away from lights etc, mine CVT rarely gets past 2000 revs, before dropping to around 1800 until reaching desired speed, although when going up a certain longish hill at 80k's it does go up to 3000.
Now when in Sydney I do notice that I then need to get the revs up to stay with the flow of traffic.
It would be interesting to know your fuel consumption when you constantly rev up 3000 when accelerating.

JATCO CVT8 Brand New Transmission

The X-TRAIL CVT Transmission is manufactured by JATCO and it is the JF011E type.
Some of you already know that the existing CVT Transmission used in the T31 Exy (and many other car makes) is made by JATCO - Japan and it is the JF011E series.
JATCO made an announcement on the 22nd of November, 2011 introducing a brand new CVT Transmission called the CVT8 Series and the CVT8 Hybrid and intropduced this new CVT to the public at the Tokyo Motor Show this year.
The new CVT is for midsize and large front-wheel drive vehicles, offering an improvement of 10% in fuel economy compared to earlier models.
Designed for application with 2.0 to 3.5 litre engined vehicles, the CVT 8 features a ratio spread of 7.0:1, which is around 15% higher than current models. Friction is 40% down for the unit, which features Adaptive Shift Control as part of the kit.
The CVT8 is to be introduced next year, debuting in vehicles in North America, and will be built in both Mexico and Japan. The company has also announced the CVT8 Hybrid, developed in conjuction with Nissan. The system incorporates an electric motor and two clutches into the unit, offering a compact, versatile powertrain that does not require a specially designed body. Nissan plans to release a new hybrid vehicle with this system in the US in 2013.
John has previously posted an excellent video showing the CVT8 in action and it can be viewed below:
This was taken from the full article in Autoblog which you can VIEW HERE.
The above may mean that we will be seeing a new series T31 (or T32) X-TRAIL with this new transmission, so it will be an exciting improvement if and when it happens
