A powertrain assembly including a powertrain unit with a drive shaft, at least a first mount and at least a first coupling arm, arranged to direct the drive shaft substantially perpendicular to a driving direction of the vehicle. The first mount is arranged substantially perpendicular to the drive shaft. The first coupling arm is arranged between a first end side of the powertrain unit and the first mount and is connected to the powertrain unit by at least a first fixing element to hold the powertrain unit in an initial position. The first coupling arm is configured to clash into the first mount in case of a vehicle collision. The first fixing element is configured to be sheared off from the first coupling arm to at least partially disconnect the powertrain unit from the first coupling arms after the clash of the first coupling arm into the first mount.

Powertrain assembly for a vehicle

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.

Subframe assembly for a vehicle utilizing scaleable multi-cell extruded siderail members

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.
