Abstract
Disclosed herein is a rear subframe and suspension system. The subframe may be configured to accommodate one or two electric motors for propelling an automobile. The subframe may be configured such that the motor(s) is inserted through the front end of the subframe. The subframe may substantially surround the motor. Braces may be the coupled to the subframe to secure the motor within the subframe. The subframe may further include built-in motor mounts. An independent rear suspension system and rear steering system may also be coupled to the subframe.

A rear subframe and rear steering assembly system comprising:
- at least two castings extending in a longitudinal direction and spaced apart from one another in a lateral direction;
- the at least two castings coupled together by a laterally extending front cross-car extrusion and a laterally extending rear cross-car extrusion, the rear cross-car extrusion spaced away from the front cross-car extrusion in the longitudinal direction to define an area that is bounded by the at least two castings, the laterally extending front cross-car extrusion, and the laterally extending rear cross-car extrusion;
- a laterally extending roll bar coupled to the at least two castings and positioned over the area to define a motor receiving volume configured to contain at least one motor;
- and
- a rear steering actuator mounted to a rear facing surface of the rear cross-car extrusion.
A method of installing an electric motor in a rear subframe:
- inserting at least one electric motor into a front side of the rear subframe configured to at least partially surround the electric motor on all sides except for the front side;
- and
- securing at least two braces to the subframe to close the front end and at least partially surround the electric motor on all sides.
