Does SUV need front and rear bumpers and sub-bumpers? Why are the front and rear bumpers made of plastic?

SUV is a common type of vehicle on the road, and the bumper is a vehicle configuration with a protective function, mainly installed at the front and rear of the vehicle. So should SUV cars be equipped with bumper sub-bars?

Does SUV need front and rear bumper sub-bars

It can be installed according to personal needs, but the editor recommends installing it.

The bumper has two functions: one is to protect pedestrians. Pedestrians are vulnerable when people and vehicles collide. In the collision test, special attention is paid to the impact force on the lower leg. The buffering effect of the bumper can reduce the degree of injury to pedestrians when they are hit. The other function is to reduce the loss of vehicle parts during the collision, which is of course secondary.

Adding bumpers is certainly better, and according to regulations, if small cars are equipped with front and rear anti-collision devices, the motor vehicle owner does not need to go through the change registration process as long as it does not affect safety and license plate identification.

There are two points to note when adding a bumper to an SUV:

1. The bumper must be made of plastic. Plastic has good elasticity, which helps to alleviate the impact and protect pedestrians, reducing the degree of injury to pedestrians;

2. Adding a bumper to an SUV will change the vehicle's wind resistance, so fuel consumption will also increase accordingly, but the added fuel consumption can basically be ignored.

Why are the front and rear bumpers made of plastic?

Lightweight is the biggest feature, and the benefits of lightweight cars are numerous. Plastic is lighter than steel or aluminum, which naturally contributes to lightweight improvements. In addition, due to the low weight of the front of the car, it also helps to have good control.

In addition, due to the strong plasticity of plastic, very complex bumpers can be manufactured according to the design of the car body. In addition to taking aerodynamics into consideration, the visual effect will also be better.

The most important thing is the protection of pedestrians. The bumpers of many car models, especially Japanese cars, are soft and can be pressed down with fingers. This design can not only protect the car body from damage in small collisions, but also minimize the damage to pedestrians when colliding with them.
