A subframe assembly for a vehicle utilizing straight, parallel extruded longitudinal siderail members. This subframe assembly provides front-end (or rear-end) crash energy absorbance by plastically deforming, crumpling, and bending down to avoid the stackup and occupant cabin intrusion of components, such as the attached engine/motor, engine/motor mounts, steering components, and suspension components. The laterally disposed longitudinal siderail members each provide a straight, substantially uninterrupted lower load path to transfer crash energy from the lower load path crash management system beam and crashboxes or the like to a rear upper load path body in white bracket, and ultimately to the battery frame in the event of a crash, with the siderail members and crashboxes optionally being longitudinally coaxially aligned.
