What Are The Interior And Exterior Trim Components Of A Car?

Exterior Trim Components
Core Structural Components
Front and Rear Bumpers: Absorb impact forces during low-speed collisions to minimize body damage while also serving an aesthetic purpose.
Front Grille: Facilitates heat dissipation and ventilation for the engine compartment; this component may be simplified or eliminated in new energy vehicle models.
Front and Rear Fenders: Cover the wheel areas to protect tires and surrounding structures; they are designed for easy repair or replacement in the event of scrapes or impacts.

Protection and Airflow Components
Side Skirts (Rocker Panels): Protect the vehicle's underbody from stone chips and optimize airflow to reduce wind resistance.
Spoilers (Rear Wings): Optimize aerodynamic performance and enhance driving stability.
Wheel Arch Liners and Mudguards: Prevent wheels from kicking mud or gravel into the vehicle body or engine compartment.

Other Exterior Trim Components
Exterior rearview mirrors, door and window trim strips, roof trim strips, roof racks, body badges, quarter glass, sealing systems, cowl panels (windshield base water channels), etc.
