Based upon an arched decussate (shaped like an X) form from which the chassis is suspended, this is a motor vehicle in which all components are sprung members. This enables a flexible and extremely light-weight bed upon which to mount a propulsive system. As part of the design, passenger loading will never impart uneven stresses upon the vehicle. Furthermore, depending upon the power unit, the vehicle can be lifted by the end to facilitate parking. The proposed model employs either a ceramic replaceable power unit burning fossil fuel, or an electric or hybrid power supply. The advantage of the extreme lightness is such that a 100 cc motorcycle engine is adequate to drive it, even with two up.
