Recently, global warming becomes serious problem all over the world. One reason for the greenhouse gas is CO2 in the exhaust gas from automobile. It is necessary to develop high- efficient engine such as hybrid system using internal combustion engine and electric motor or only electric motor. The purpose of this research is to analyze the sound quality of electric vehicles and to estimate their positions among conventional internal combustion engine vehicles. First, subjective evaluations of internal combustion engine and electric vehicle in the case with train and without it are examined by semantic differential method. Then, the specific factors of both cases are extracted by factor analysis. Moreover, the sound quality of the electric vehicle is characterized for next-generation.
