Prominence Commuting Device(PCD) is electric vehicle becoming less than CO2 emission basic unit of Well to Wheel of passenger railway in a occurring by transport of one adult. PCD acquires a license plate as “moped car” and can really run public roads. The CO2 emission basic unit in Well to Wheel of PCD is 13.4g-CO2/ person*kilometer , which is less than Japanese passenger railway (18g-CO2/person kilometer). PCD can run 90km by one charge, and Its highest speed is 75km/h. This vehicle performance and environmental performance are realized by pursuit of lightweighting and the aerodynamics performance as well as the electrification of the vehicle.
