如果你是头像中那辆inspira车主，那么你的变速箱是源自日本的Jatco，并不是Punch的。

我是用Insprira，也是第一次用CVT。。所以还是有很多东西不会。。

punch 和 jatco應該是品牌名。而torque converter cvt應該是類型。wiki或google應該會有。

还是Manual好。。。。

monster.inc

所以還是買manual 安全點。

看了两页，还是没人解释PUNCH　CVT？等待师傅。

不要这样说么，这样的价码，买这样的车，人家给很多丰富的配备。
只是更换其他的CVT,又不代表目前的一定会坏。

Iriz sedan 会不会很奇怪？不如出persona 新版。

出persona新版不如出wira第二代…延续以前的神车之名

这里破铜信徒很多，万一解释错了会引起骂战的…

什么叫情归何处？

情以何堪是吗。。。

也可能是情何以堪？

Iriz是车身比较高的车，如果做sedan能看？

对不起，请原谅我不会欣赏破铜车…不管iriz是不是sedan我都觉得很难看…

Punch是品牌名字，现在最好的CVT制造商应该是nissan吧？
还有其他的厂商是特别制造Transmission system的，Getrag就是其中之一，Aisin也是，等等等等。
通常车厂为了节省开发成本会把某些车内系统交给行家做，比如说车内电子和安全系统就交给出名的Bosch, Siemens, 等等。

而Torque converter CVT是另外一种CVT，他和普通的CVT不一样的是加了Torque converter让你起步更有feel,因为torque converter这个东西其实很神奇一下的～

详情就大家去wiki wiki下youtube youtube下巴～～～

读读这个吧

want to share bits on punch cvt2 . the improvement same as suprima cvt3 . the fd ratio being change compare to flx cvt2 to match with new vvt engine powerband.

punch cvt operate diff compare to other cvt.

from stagnant,it rev higher than tc cvt due to clutch action.

city driving,to get most fc,rev below 2k rpm,circa 1600rpm to 1900 rpm,but 1900 rpm will be the most balance on power n fc. why,at that rpm range, cvt will try to change from low ratio to high ratio asap to get most efficient fc. 2100 to 2500 rpm is just enough to overtake in city driving.

eventhough the torque isnt that high, but cvt being tuned diff when 2k rpm n beyond,it holds longer on low ratio b4 switch to high ratio. this help on acceleration,but sacrificing a bit on fc,but not too much cuz u dont need to rev as high as in prev 4at.

the wrong thing previously done that consume too much fc,many tend to treat it like conv at, rev as high as 2500rpm from stagnant,then reduce the throttle when achieve desire speed.

its wrong then.eventhough but o meter feel slow,its not as slow as as one might think.

even at higher speed such as 100kmh,no need to rev too much, rev 500 rpm than prev rpm,just enough to overtake,unless u need all the torque,then 4k rpm is needed. wot is only needed when u have need for speed.

when hill climbing at genting road for example,drive in D is sufficient ennough,but if need more attach feeling,just switch to L,so that low ratio will be used all the way,n if course,even in normal at,u only used low ratio during hill climbing at genting,unless its cfe,L is rarely needed.


yup, cvt drooning its there when low ratio is used,but it become.lesser when it switch to high ratio. thats why rev below 2krpm,the drooning will only heard shortly cuz it will shift to high ratio asap.

hope this help future owner of iriz to understand how punch cvt operating. dont compare it with tc cvt,its not the same.

why clutch cvt,look at independent testing in thailand,lookup for preve cfe n lancer 2.0 gt real performance. during wot, turbo cfe doesnt have much advantage over 2.0 mivec coz both usibg cvt,n both rev at most optimal rpm for the engine. lancer 2.0 torque isnt that shy from cfe,n its lighter than preve,n it shows that wet clutch cvt still have an edge over tc cvt.

its only lack if feeling refinrment and the drooning cvt sound. even lighter dual vvti cvt altis miss the mark.

im not saying that its godly good,but nothing perfect n punch cvt isnt as weak as some might think. punch keep improving its product,in future,maybe the lack of refinement can be cater in.

自讨苦吃不值得可怜？我看不出他们很可怜或在吃苦，又不是说现在的差到不能开，反而是买了vios, almera的 ...

新加坡只有jazz在用 。如果vios用dual vvti加s-cvt..相信油耗会比city来得好，不过讲讲就好，发梦总是美好的，现实的总是残忍的。看toyota要不要给而已

呵呵，不管只是研究罢了，还是打算换了，都叫Iriz现有车主情何以堪。
