Bonnet

Bonnet assemblies comprise the hinged, removable steel or alloy panel covering the engine compartment of front-engine vehicles. Primarily functioning as an access panel for engine service and a crucial component of vehicle frontal structure, bonnets contribute to impact energy absorption. Construction typically involves a pressed steel skin supported by internal bracing and attached to a latching mechanism for secure closure. Many modern bonnets integrate aerodynamic features or pedestrian safety designs, such as raised central sections or energy-absorbing understructures. Material selection balances weight reduction with structural rigidity and corrosion resistance.
