"World Econo Move" is the event competing for the driving distance with the battery in an equal condition. We designed and manufactured new Econo Move car with the aim of the low air resistance. And we tested performance of new model. From the data, drag coefficient and coefficient of rolling resistance were calculated. Comparing new model with 1998 model, it was clear that watt consumption of new model is 9 percent less than that of 1998.
