Maybe you've discovered it a long time ago
a lot ofcarThere is one in the center of the back rowRaised

And this bump alsoHigh and lowBut no matter how low it is, it directly affects the comfort of the rear seat

If two people sit in the back row
It doesn’t matter if you get on the left and right.

And if you want to get on and off on the same side
The one inside will be more strenuous to get in and out
Have to climb over the mountains

The saddest thing is when there are three people in the back row
The one in the middle will be very embarrassing

But even though it is so inconvenient
Some drivers like it
Especially the beauties sitting in the mid

Still very interesting

But the problem is still coming
Why is this bump used?
Why is there that bump

Some people say it is mainly for partitioning
Just like separating the living room and dining room during house renovation

This is a silly break from Xiaoxiao's point of view
So Teng Xiaoxiao specifically consulted friends far abroad
A senior car designer

I know after asking
The reason for this bulge
Totally
Chassis and power train layout
s reason

usually
The center of the chassis must pass
Exhaust pipes, brake pipes and other pipelines
Or drive shaft, or arrange rear suspension

For the chassis level
I had to sacrifice the space in the car as a last resort
So the middle of the back row will bulge

Then why is the bulge high and low?

In other words, this has a certain relationship with the driving mode of the vehicle
Front rear drive
To passtransmission shaftTransmission of power to the rear wheels
So the bulge will be higher

4WD because ofRear axle,Shock absorber
Also consider increasing the ground clearance to improve passing performance
So the bump is generally higher

By contrast
The bump of the front-wheel drive vehicle is generally lower

But because some vehicles have multiple versions such as front-wheel drive and four-wheel drive
And in order to save costs
The car factory will not make two different molds
So some front-wheel drive cars have very high bumps

Therefore, simply by the height of the bump
To judge that the front-wheel drive and rear-wheel drive four-wheel drive are not feasible
In addition, someone said
Raised height and
Vehicle design philosophy and laws
Have a certain relationship
For example, some vehicles are basically driven by one person
Almost no people in the back row
It doesn’t matter if the bulge is higher
And if the vehicle is designed with 3 people in the back row
Then the bump height will be minimized

Speaking of law
It is said that Europe has stipulatedexhaust pipeNot too close to the ground
To avoid high temperature damage to lawn pavement, etc.

And in the case of the same chassis height
To achieve this effect
Can only use the space in the car

But you must also know
Many cars have no bumps in the rear
Why is this?

There are two situations
One is the high ground clearance of the vehicle itself
There is enough space available outside
No need to take up space in the car

One is that the exhaust pipe is designed very low
Does not take up space in the car

Such a small bump
There are so many ways
Didn't expect it?
