如果踩离合器踩到底，但是减速过程不downshift,是不是对车有严重损害？ |

发帖数: 371 | 3 请问大虾，能说说轻踩着离合为什么不是好习惯吗？
另外，
减速的过程，一个一个downshift对新手太难
速度降低的过程对新手，踩离合换空挡，然后踩刹车？还是先刹车，然后挂空挡？
速度从10开始降低，只要不是0，只踩刹车，不睬离合器，对档位分别是是N挡和1挡两
种情况，应该都不会熄火？

New Volkswagen Jetta disappoints
The newly redesigned Volkswagen Jetta now ranks last among the 11 small
sedans that have been tested by Consumer Reports. Engineers found fault
with its agility, cornering grip, coarse engine, braking, interior fit
and finish, and so-so fuel economy.

WRX 5-door Limited，Short Throw Shifter + STi Knob, Body-side molding，算

2个月没车开的日子终于结束了，昨天提车就在城里转了将近80迈，1000磨合所以没踩
过4k转。
动力够足，低转的扭矩也不是很差，lag有但是不是太明显。5速手动和Si上的不能比（
即使是换了SST和STi bushing也是），downshift到三档有时候塞不进去，离合稍长点
，不过在期待之中也倒可以忍。
风噪路噪都有，比Si小一些，排气要安静许多。悬挂照Si软一些。
总之目前为止很满意。先上照片凑合看看。

这是第11代卡罗拉，为了吸引更年轻的用户而非维持以往用户，继“Avalon”
及“RAV4”之后，丰田再次采用了个性强烈的外观设计。前脸以较扁的前大灯以及下部
带大开口的保险杠等为特点，并搭配大幅膨出的翼子板以及向后平缓下滑的C柱。
新款卡罗拉的外形尺寸为长4639×宽1776×高1455mm，与上代车型相比车长增
加99mm，车宽扩大16mm，但车高降低10mm。轴距为2700mm，比上代车型长100mm。由于
轴距更长，因此后座臀点后移了75mm，另外还通过减薄前座靠背，使后座乘坐空间变得
宽敞。

But for city driving, constant turning and braking, especially crossing the

railroads), use heel to toe downshifting when you can, or if it is
