An apparatus and methods are provided for a front structural bulkhead for improving the strength of an off-road vehicle chassis. The chassis is a welded-tube variety of chassis that includes a front portion and a rear portion that are joined to an intervening passenger cabin portion. Frontward stays and a bulkhead mount couple the front structural bulkhead to the front portion. Bulkhead mount pillars and a bulkhead mount crossmember couple the front structural bulkhead to the passenger cabin portion. The front structural bulkhead includes a modular chassis for supporting drivetrain components that are operably coupled with front wheels of the vehicle. The front structural bulkhead includes upper and lower mounting points configured to receive front suspension controls arms. The upper and lower mounting points are configured to allow the front wheels to move vertically due to the vehicle traveling over terrain.

An electric vehicle, including, a user compartment and a front section including a portion of a vehicle chassis, a crash absorbing member located in the front section and connected to the portion of the vehicle chassis, the crash absorbing member including a first extruded profile, preferably an aluminum profile, having a main extension direction in a transverse direction (y) of the vehicle, whereby the extrusion direction of the first extruded profile extends substantially in the transverse direction (y) of the vehicle, and wherein further the first extruded profile includes at least two cells (C1, C2) being defined by outer walls and at least one intermediate wall separating the at least two cells (C1, C2), wherein the at least one intermediate wall has a main extension direction in the transverse direction (y) and a second extension direction which extends substantially in a vertical direction (z).

A vehicle may include: a floor panel; a rocker extending along a side edge of the floor panel; a rear side member located on a rear side of the rocker and extending along a front-rear direction of the vehicle; and a suspension. The suspension may include a trailing arm; and a bracket connected to the trailing arm via a bush. The bracket may be fastened to the rocker at a first fastening point by a first bolt and fastened to the rear side member at a second fastening point by a second bolt.
