Abstract

A method of assembling vehicles includes providing an X-by-wire chassis and mounting a vehicle body at an upper face of the chassis. The vehicle body includes a body frame, a seating apparatus and one or more body panels, and may include a floor. The vehicle body may include one or more preassembled body modules. The invention contemplates that the body may be operatively connected to the chassis when it is mounted at the upper face of the chassis so that one or more of the systems in the chassis that are responsive to non-mechanical control signals will respond to such signals.
