I believe that many owners will find it，Now the new car will not be installed with mud boards，Is this a car manufacturer secretly reduced? So，After buying a car，Is it necessary for us to install the mud board?

First, let's take a look at the effect of the mud board?

First，From this literal meaning，The mud board is used to resist the mud。Generally in rainy weather，Especially on the muddy road，There will be a lot of mud on the car tires，Sometimes I still get it on the car body。And the mud board can effectively cover the mud water driven by the car during driving、sand grains，Prevent mud water from splashing the body and passengers when the passengers get on and off the door，Dirty clothes。

In addition to the wing board behind the wheels，The mud board is to a certain extent，It can help keep the tail of the car clean。Granules brought by wheels、Dirty things，Not only does it seabet loginfly directly to the wingspan，Some will also be dragged under the airflow of the bottom of the car，Arrive at the tail of the car，Get up by the air flow rotation by the rear of the car，Stay on the buttocks。Especially the hatchback、SUV、MPV models，The sediment is also easier to be rolled up，Stay on the rear glass window。

If there is no installation of mud boards，So when the car is flying，It happens to be rainy weather，Especially the rear tire，Like a pumping machine，Water drops splattered，Bringing inconvenience to other pedestrians on the road。

Second，We know，If you do n’t pay attention when washing your car，Directly use high -pressure water spray guns to wash or rub it with rags，Sandy and car paint surface "friction motion"，Damaged car paint surface。and the pad can reduce the sandy adhesion to the body，Avoid floating car paint。

Since there are so many benefits to the mud board，So why do almost all new cars leave the factory，Nothing to install the mud board? Actually，The mud board also has the following side effects:

1. Through sex

Installation of mud boards will affect the passability of the vehicle to a certain extent，Especially the models that are relatively low in the chassis itself。

2. Increase pneumatic resistance

Related studies found，Installed mud boards，The turbulence at the rear of the car will be larger than the original model，The resistance is even greater。

When our car is driving at high speed，It will receive very large air resistance，When our car speed exceeds 80km/h，The resistance of air can account for about 60%of the total resistance of the car。

seabet ioWhen the speed is faster, the faster the speed，The resistance of the car will be faster，So in order to reduce our car air resistance，When developing cars, our cars will be designed as streamlined，and the bottom of the car is also designed very flat，This can allow the air to flow quickly，Our wind resistance coefficient will also be reduced a lot。

If a mud board is installed，It is equivalent to the total resistance increased by about 5%。Assume that other conditions are the same，5%of the fuel consumption out of thin air，It will also bring some additional noise of "Hoh Hoh Shasha"。

So the reason why today's cars are not installed with mud boards，In terms of performance, it is very reasonable。

3. There is a little impact on whether the car will flutter

greater pneumatic resistance also means when driving at high speed，The air flow rate will become slower，Stop it for。According to the principle of Berinley，The pneumatic liter of the car will also become larger，Driving will feel that the car is easy to flutter。

Some researchers also did some experiments on a certain model，At 80 kilometers per hour, per hour，Putting a car with a mud board，Pneumatic lift increases 57.1%。Although this is not enough to lift a car，But I will feel a little floating。

So, do you want to install the mud board?

If it is a SUV model，or running often，The mud board is still a bit of a function，can reduce the accumulation of sediment in the body，But most of the time open in the city，All cement or asphalt roads，Good road conditions，The body is relatively clean，It is an ordinary car，Is it unnecessary to install the mud board。
