Body panels are the exterior parts of a vehicle that form its structure and shape. These panels include components like the hood, doors, fenders, and trunk lid. They are typically made from materials such as steel, aluminum, or plastic, and are designed to protect the internal components of the vehicle while also contributing to its overall aesthetic appeal. The primary function of body panels is to provide safety and support for the vehicle's frame. They also play a crucial role in aerodynamics, helping to reduce drag and improve fuel efficiency. Additionally, body panels can be painted or finished in various colors and styles, allowing for customization and personalization of the vehicle.
