Abstract
A chassis assembly of a vehicle includes a frame, an underbody supported by the frame, and a subframe connected to the underbody. A connection connects the subframe and the underbody. A lever extends from the subframe to the frame. During a frontal impact of the vehicle, the lever leverages against the frame to detach the connection from the underbody. This movement of the subframe relative to the frame and the detachment of the connection from the underbody absorbs energy during the frontal impact and results in a softer pulse and a reduced Vehicle Pulse Index.
