A vehicle chassis having substantially all of the mechanical, electrical, and structural componentry necessary for a fully functional vehicle includes at least an energy conversion system, a steering system, and a braking system. The chassis is configured for matability with a variety of different types or styles of vehicle bodies. Various prior art mechanical control linkages between a driver and controlled systems are replaced with non-mechanical control signal transmission components. Fuel cell technology is also implemented. Further, the chassis is configured for automatic engagement of its body connection components with complementary connection components on a vehicle body when a body is sufficiently positioned against the chassis.
