What is the name of the protective panel above the car tire?

[SanFelix]

The panel above the tire is called a mudguard, primarily serving to block mud and dust. It is usually installed behind the four tires of a car, with the front two fixed on the left and right lower sills and the rear two fixed on the rear bumper. The entire mudguard consists of two layers: the outer hard layer is the wheel arch, commonly black, and the inner soft layer is the liner. The mudguard is composed of the wheel arch and the liner. Functions of the mudguard: 1. Prevent mud from splashing onto the car body or people, which can make them look unattractive. 2. While driving, it can block gravel and mud kicked up by the wheels. 3. Enhance the overall aesthetics of the car body. 4. Reduce the drag coefficient, making driving more stable.
