A siderail member for a subframe assembly of a vehicle, including: an elongate body, wherein the elongate body includes a hollow extruded structure including an inboard wall, an outboard wall, a top wall, a bottom wall, and one or more internal walls. Optionally, the bottom wall has a thickness that is greater than a thickness of the top wall. Optionally, the outboard wall has a thickness that is greater than a thickness of the inboard wall. Optionally, the one or more internal walls include a top internal wall and a bottom internal wall forming a plurality of horizontally-disposed cells within an interior of the elongate body. The bottom internal wall has a thickness that is greater than a thickness of the top internal wall. The hollow extruded structure is manufactured from an aluminum material. Optionally, the top wall of the hollow extruded structure defines a flexure recess.

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.

A vehicle body structure includes an engine cradle and an impact receiving structure. A forward end of the first side portion and a first lateral end of a front portion of the engine cradle are fixedly attached to one another. The first side portion has a rearward section and a forward section, the rearward section being horizontally oriented and the forward section extending upward and forward from the rearward section defining an acute angle therebetween, the acute angle being between 30 and 35 degrees. The impact receiving structure is installed to the first side portion of the engine cradle proximate an intersection between the first side portion and the front member. A lower surface of the impact receiving structure extends downward along the forward section of the first side portion further defining the acute angle of the forward section of the first side portion of the engine cradle.
