Depleting of fossil fuel, contamination of atmosphere, traffic congestion, and so on, car life scene of recent years demands of mobility which is able to drive with smallest size of body and fewest energy. Now then, this project will produce "Ultra Light Vehicle" (ULV) which is able to drive with smallest size of body and fewest energy, and consider a method of decreasing environmental load and improvement model of "manufacturing in local and exploiting in local", which model of ULV is able to assembled by local small and medium-sized enterprises, and used effectively in local area. So, this project aim to realization of futurity mobility from community. In addition, aiming to "manufacturing in local and exploiting in local" model of ULV, this project will realize "Multi-PM"ULV, which model is able to choose suitable prime mover for area. Finally , this project consider these things, and aim ULV to spread and use effectively.
