A lower frame rail member forms a part of an automotive front end structure and incorporates first and second bending hinges to provide sequential and alternating bending of the lower frame rail to manage crash forces in the event of a frontal or offset crash event. The first bending hinge is formed by a structural thinning pocket located on the outboard side of the lower frame rail forwardly of the engine mounting bracket. The second bending hinge is formed by V-necking the inboard side of the lower frame rail rearwardly of the engine mounting bracket. The first bending hinge affects an outboard buckling of the frame rail after the front horn section crushes rearwardly into the lower frame rail to induce an inboard movement thereof, while the second bending hinge affects an inboard buckling of the frame rail to induce an outboard movement thereof rearwardly of the engine mounting bracket.
