Engine Compartment Lid
The two-piece engine compartment lid is in aluminum and the inner panel has a hexagonal panel structure, which allows energy from a pedestrian head impact to be absorbed effectively across the full area of the bonnet. It also has sufficient strength in the rear cross-beam to accept the forces from the actuators and maintain a stable condition.
When deployed, front bonnet latch acts as the pivot point and the rear hinges allow a controlled degree of upward movement before retaining the bonnet at the end of its deployment, thus limiting its total upward travel and stabilizing its position.

The hinge system incorporates a number of leaves. This includes a leaf attached to the body, an intermediate leaf and a leaf attached to the hood. During normal operation the hinge opens and closes using the hood and intermediate leaves. These are attached together by a firing pin. When the actuators are fired the firing pins fail. This allows the hood and intermediate leaves to separate and deploy the hood upwards. When the hood deploys the hood latches act as temporary hinges.
