However, although second-generation Prius has a 1500-cc engine, it is treated as a medium-size car with a license plate whose number starts from 3 because its width is over 1.7 meter, and thus its demand is not as high as the first generation in areas where majority of the taxis are compact cars.
しかし、2代目プリウスは1500ccエンジン搭載車であるにもかかわらず、横幅が1.7mを越えた3ナンバーになってしまい中型車として扱われるため、小型車中心の地域では初代ほど登録されていない。
