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.

Abstract: Techniques for injecting a vehicle into a high speed transportation system are described. A travel request is received from a user. The user is determined to be authorized to travel using the high speed transportation system, based on a profile associated with the user. An injection portal for the user to enter the transportation system is identified. One or more instructions for the user are provided, relating to the injection portal. A vehicle associated with the user is identified at the injection portal. Characteristics of the vehicle are sensed at the injection portal, including a center of gravity of the vehicle. The characteristics are determined to satisfy threshold values, and the vehicle is authorized for travel in the transportation system. A vehicle profile is generated. The vehicle profile is transmitted to a second controller associated with the transportation system. The vehicle is injected into the transportation system.
