不是有问题。。。只是当大家都换回timing chain 时它还是用timing belt。。。还有就是它 ...

你的意识是TIMING CHAIN比TIMING BELT先进？？？？
你懂P2为什么用TIMING CHAIN吗？

Timing chain
Timing ChainTIming chains have been widely used before timing belts popularity explosion in 70's-80's.
As a general rule (not necessarily true today) timing chains are noisier, they are for sure require higher mechanics' qualification to maintain and they last much longer than a timing belts.
- Timing chain require a tensioner and if used for S(D)OHC - require a quieting shoe. In many cases one of them may serve both roles and two tensioner/quieter shoes could be used.
- Chain is usually heavier per inch length than belt and therefore require stronger infrastructure to hold it in place. In case chain get stretched over time and go above tensioner's adjustment capability things could go hairy fast. Engine's timing may become erratic.
- Timing chain in general is very reliable and require only every so often check-ups. Modern ECU could be capable of troubleshooting timing chain issues which increases reliability of the whole system.
- Timing chain usually enclosed within an engine case and constantly lubricated.

Timing belt
Timing BeltWith introduction of a new materials in 60's and 70's it became feasible to have very dependable engine timing system that is light, easily serviceable and cheap at the same time.
- Timing belt drive usually quieter than a chain drive. Since belt is lighter it requires lighter support structures and does not need a calming shoe.
- As a result SOHC/DOHC engines could have higher RPMs without worry of an added chain momentum.
- Timing belt must be changed every 50-75 thousand miles along with the tensioner and a water pump if one driven by the timing belt.

In 2009 model year we see a new trend of car manufacturers moving back to timing chain engine design. Many of them rely on a service data and price/performance evaluation for the size of the vehicle.
It is unlikely that general public will know exact figures on timing belt/chain price/performance comparison but we all have our own preferences and that may become a driving force for the future engine models.

不是，timing belt是比较新的科技，不过因为维修时间比较短。。所以就浪费很多时间和不太环保。。每60k就必须换一条。。。一过了会断掉。。长时间没驾也会变质。。。是商家撩钱的计量。。
timing chain虽然贵些但是普通一般人都不需烦。。。因为通常是变长了或走位了才需要维修。。。
一次大概是5-6年才一趟。。。有些还可以耐上8年。。。。

我只能说各有各好。。因为引擎设计需要，TIMING BELT/CHAIN根本不是一个问题。。。
而且现在的BELT是有100，000KM的

   那当然。。。喜欢普通只会支持它。。。喜欢第二就只会买第二。。。   大家都给很普通的车公司骗到怕了。。就没有信心了。。。

我选Saga.+1

这个很久以前也，还可以被你找到哦。。。
我朋友最后选择myvi因为复合他的size，还有他说resale value高点，都service几次了。

我自己是亲身体验过。我给myvi撞，结果我车只是刮伤，而他的bumper却掉了下来，还凹进去

atos那么小辆做什么耗油量会相当惊人？

对楼主来说只有SAGA是最省油的。
