What is the plastic next to the fender?

[Daniella]

The plastic next to the fender is called the wheel arch trim. Below is relevant information about the fender: 1. Introduction to the fender: The fender, also known as the wing panel (Fender), is categorized into front fender and rear fender based on its installation position. It refers to a type of covering component on motor vehicles and non-motor vehicles. 2. Function of the fender: The fender is also called the wing panel (named for its shape and position resembling a bird's wing on older vehicle bodies). The fender is located on the outer side of the wheel. Its function, according to fluid dynamics, is to reduce the drag coefficient, making the vehicle's movement more stable. Based on installation position, it is divided into front fender and rear fender. The front fender prevents gravel and mud kicked up by the wheels from splashing onto the underside of the vehicle during driving, thereby reducing damage and corrosion to the chassis.
