前後驅問題?

It is all because the FWD vehicles are easy to control and also very easy for maintainance. RWD vehicles are better on performance but it needs a bigger and more powerful engine! Also their fuel consumption will be a lot better than the 4WD vehicles!
This is why most of the saloon are FWD and RWD! But mostly are FWD!
And one more important point is smaller engine need smaller space!
There are alot of reasons i cannot tell you all, since there are alot of theory behind this!
