The hood (called the bonnet in the UK and some other regions) is the hinged cover that sits over the engine bay at the front of the vehicle.
The hood or bonnet usually opens by hinges near the windshield and is held shut by a latch.
Functions of the Hood
Protection – Shields the engine, battery, radiator, and other vital components from weather, dirt, and debris.
Accessibility – Provides access for maintenance, inspections, and repairs.
Aerodynamics – Shapes airflow over the vehicle for fuel efficiency and stability.
Safety – Modern hoods are designed with crumple zones or active hoods (that lift slightly during pedestrian impact) for crash protection.                                                                                                                                                    Materials mostly used to make the bonnet or hood are:
Steel – Durable and most common.
Aluminum – Lightweight and resistant to rust (common in modern cars).
Carbon Fiber / Fiberglass – Used in sports or custom vehicles for weight savings.
