A support extrusion for a subframe structure of a vehicle and methods of fabricating the same. In one example, a support extrusion can comprise a multicell structure that facilitates coupling the support extrusion with a rear crossmember of the subframe structure. The multicell structure can comprise a front cell column and a rear cell column that intervenes between the front cell column and the rear crossmember in a longitudinal direction of the subframe structure. The front cell column can comprise a trigger that facilitates plastically deforming the front cell column downward in a vertical direction of the subframe structure when subjected to impact forces of a frontal crash.
