pupa electric vehicle

Capable of 60 km/hour and a cruising range of 100 km, a very lightweight electric concept car from the Teijin Group's  uses proprietary materials and technologies including carbon fiber composites, polycarbonate resins and bio-derived polyester. Weighing only 437 kg, less than half that of conventional electric vehicles, the PU_PA EV (as in “pupa electric vehicle,” a reference to metamorphosis) embodies Teijin’s vision of what a vehicle will look like on the market in five to ten years. T he PU_PA EV offers the functionality and structural integrity of a practical automobile.
