那就先刹车减速
然后downshift
再过弯
downshift不平滑就练downshift,跟过不过弯没关系

可是autocross的时候有些人会在某些u型弯downshift到一档.
如果没有同步器按说就非常难downshift进去了..
不过我听到的说autocross二档到底的原因是因为downshift没必要,直道本来就短,加速
过程中还要升一下档损失时间.得不偿失.
没有听说过是没法降回一的说法的.

downshift whenever you want on the street as long as you feel comfortable.
saadi(floor 18)'s theory is right, is it more apply for the high speed turn/
racetrack - during the turn, tires are using a great % of its capacity to
turn, if you downshift during the turn, it is risky that you can lock the
wheels (even 1/10th sec. lock) because of the engine rev mis-match, your car
would spin/slide (rear wheel drive). on the other hand, on the street, most
time you are only using less than 20% of tires'... 阅读全帖

Rpm matching during downshift does not mean there is no engine break. It
just provided a much smoother downshift.

this feature in a production car (auto rev-matching in 350z and G35). Try
drop two gears at 65 miles per hour and feel the torque when it blips to
6500 RPM, this car is just a rocket. And no C300 or even C350 can match that
. Also I think G37 is the largest of entry luxury cars.

总结了下,请教以下几个问题:
1.踩离合换挡的时候不能踩加速是不是因为 突然松离合engage的时候,转速过快对机
械系统不好?
2.减速只要保证转速不太低即可就不用downshift,但是换低档可以保证转速较高,降
低熄火的概率.急刹车直接在高档猛踩刹车都可以,不用downshift,但是可能高档转速
降低最快,造成熄火?

I have about 120,000 miles manual transmission experience.
starting from uphill with handbrake is not "necessary", just a good habit,
and the correct way to do a hill start.
and holding the car on a incline with half engaged clutch is going to kill
the clutch real soon.
手动车开的好的, would toe-heel downshift when breaking. Or at least
downshift as the car slows down.
下坡踩离合 is one of the worst driving habits.

我开过10多年的手动车
包括国内7年的golf,但是没开过GTI
试着回答你的问题
1) 你要想不jerky只能离合提得慢点,第二,转速把握的比较好。前两个挡想开平稳其
实没那么容易,油门和离合器的配合需要长时间的练习才能做到平稳,没有太大诀窍。
2)至于downshift,我觉得你如果不跑track可能用不上,因为GTI有200多马力,基本
上处于overpower状态。我以前国内的golf只有1.6NA的引擎,是在高速上超车超不动的
时候(>110kmh),或者和别人抢缝时才downshift
3)绝大多数时候不需要rev match,因为现代变速箱有同步器。但是如果速度降太多还
是挂不进去,必须得给油。例如,我家门口的高速出口匝道,拐弯半径非常小,每次我
入弯后要从6挡直接降到2挡或者3挡,这时候必须要给油。

来自主题: Automobile版 - 哪种变速箱最好
zf 9at是for transversal engine的,vw MQB就可以用,mlb可以用zf 8at,比如q7。
为什么vw MQB用爱信8at不用Honda用的zf 9at我也不知道。
ZF 9AT用了dog clutch,在4<->5换挡的时候花的时间会长一些,而且感觉比较奇特,
这个是软件解决不了的。不过总体说软件上acura做的比chrysler好多了。还有一个尿
性就是这个zf 9at有3档超速挡,有人开小妾到85mph都没能进9档。gm的9at ratio分布
就正常多了。
双离合低速顿挫国内的车比较多,因为换挡逻辑设定的是省油为主,一有机会就
upshift。同理可见hyundai的那几个DCT,都是省油为主的。这种设定下面低速不可能
不jerky。跑车用的DCT不可能顿挫吧。。我没开过也没听人说过。。。
我觉得吧开多了就知道自己车变速箱的尿性,基本可以避免reluctant to downshift。
变速箱逻辑都是死的,你开多了就知道什么情况下它会downshift upshift,如果愿意
牺牲一点油耗还是可以提升平顺性的。

3。downshift,autocross降一档的机会不多,不过一旦有这种180度变态慢pivot,

I am considering Audi Q5 as well. The thing is, from the research I did

gears when downshifting. Basicall, it means when you go from 30miles/hr to 5
miles/hr, you may feel a noticable transmission squeak or jerk. Also, the
option for Q5 is very expensive, if you want premium plus + Sline + Nav, the

我从高速下来的时候想用engine帮助减速,就打到sports,因为看不到档位,就

是不是我用的不对? 觉得这个设计不是make sense。 我的volvo换手动模式的时候

You still can if you press gas pedal lightly and let go to cancel the rev-
matching. So about 2~3 seconds delay. Then the downshifted engine will have
some breaking effect on for example a long down slope.
Otherwise I'd just brake. No need for engine brake to help.

I had an 09. Very fun to drive. it's not as fast as my current G35, but with
the paddle shifter it's easy to downshift and enjoy the sound of high rev
vtec engine. Plus fuel economy is really good.

前一段在这报告过车降档的时候有很强的顿挫感:

可能有的车或多或少的有这个问题,但我这俩10的sonata实在是太强了,后来我一
google就发现有很多类似的问题,是09-10 Sonta比较典型的问题 然后发现Hyundai最
近Recall过这车,然后我就找了local Hyundai service 的Dealer刷一下电脑系统,这
个问题就解决了,后来开车很smooth,完全没有顿挫感,可能别的车也有类似的recall?
另外在这里咨询一下,这个车是在Dealer手上买的,比较新所以我也没有特别仔细的查
车,在local dealer查了下发现几个问题,Transmission fluid该换了 189USD [这个
是不是太贵?该不该再Service Dealer这里换?],应该是以前的一个保养没做,Air
filter奇脏无比,也该换了,还有一些小的问题,杂七杂八的大概几百块。
挺不爽的刚买的应该很新的车就有这么多问题,Dealer都很坏,交钱以前一个态度交钱... 阅读全帖

这些属于正常维护,recall是现代的问题。所以dealer不会负责。你可以到外边找个车
铺做这些维护,或DIY一些简单的,应该会便宜很多。

transmission fluid这么贵?一半价格还马马虎虎
air filter这种东西自己换就好了,10来块的东西不值得

recall?
