An accelerated vehicle development process includes establishing a common, standardized
interface system whereby different types of vehicle bodies may be attached to a
single chassis design. Chassis and bodies are designed, manufactured and validated
independently of each other in accordance with the standardized interface system,
thereby accelerating the development process. As new bodies are designed to mate
with the previously manufactured and validated chassis, the newly designed bodies
may be developed more quickly in response to market demand and attached to the
previously validated chassis.
