Mini car manufacturers in Japan are anxiously seeking fresh engines of growth in a slowing market after cutthroat competition for market share led to a string of fuel economy scandals this year. Mitsubishi Motors, desperate for better mileage numbers, went astray by falsifying them. And Suzuki Motor employed testing methods not specified under Japanese law. With Mitsubishi Motors trying to rebuild under Nissan Motor, and Suzuki collaborating with Toyota Motor, the market will have just three main players: these two groups and Honda Motor. Jazzing up new offerings in areas other than fuel efficiency is a key concern for all.
