An automotive hood, also known as a bonnet in some regions, is a hinged cover that rests over the engine compartment of a vehicle. Its primary function is to protect the engine and other essential components from external elements, while also providing access for maintenance and repairs. Hoods are typically made from materials like steel, aluminum, or composite materials to balance strength and weight. In addition to their protective role, automotive hoods can also contribute to a vehicle's aerodynamics and aesthetics. Many modern hoods feature designs that enhance airflow to the engine, improving performance. They may also include features like vents or scoops, which can be found on performance vehicles to help cool the engine more effectively.
