A car body is the outer shell of a vehicle that provides structure and protection for its internal components. It is designed to be aerodynamic, improving fuel efficiency and performance. The car body is typically made from materials like steel, aluminum, or plastic, which contribute to its strength and weight. The car body includes various parts such as the roof, doors, hood, and trunk. These components not only enhance the vehicle's appearance but also serve functional purposes, such as providing access to the engine and storage space. Overall, the car body plays a crucial role in both safety and aesthetics.
