Abstract: The disclosure relates to a small lightweight automotive vehicle having a frame supported on front and rear axles, a stationary front module containing an engine, drive train, controls, etc. and a rear seating module which is pivotally supported by the frame for movement about a generally vertically axis extending above the rear axles to permit easy entry into and exit from the vehicle. The vehicle could either have a single or a pair of pivotal rear seating modules and the basic geometric structural shell for the vehicle is a tetrahedron so that the seating module or modules when pivoted to an open position to permit entry to and exit from the vehicle requires relatively little side clearance.

Abstract: A three-wheeled motor vehicle has a vehicle body on which two front wheels and a single rear wheel are rotatably mounted. The vehicle body includes a front portion covering the two front wheels and having a wide and flat shape, and a rear portion having a driver's compartment and covering the rear wheel, the rear portion being narrower than the front portion and progressively higher in a rearward direction of the vehicle body. The front and rear portions of the vehicle body include slanted continuous side surfaces tapered toward a longitudinal axis of the vehicle body in the rearward direction thereof.
