Recently, an electric car is the focus of attention, with concerns about the environment. However, These electric cars have problems with cruising range, infrastructure building and so on. Especially, in country side, it is very difficult to develop the infrastructure for electric cars. Then, our design concept decide to make energy in simple batteries which is sold in supermarket and so on. And, our car designed only a few small batteries (unit 3 type: 6 batteries). However, if this small car are used by general, it need high level efficient for energy. In this research, we aim to reduce the resistance for eco-car. For the running efficiency of Eco-Car, we have developed a small electric vehicle of new design improvements and small electric vehicle. We report the evaluation of the running efficiency in flat road when it is played in the "Pico-EV・Eco Challenge 2014" in this paper.
