JAPAN // Ralliart, the Japanese high-performance subsidiary of Mitsubishi, has announced plans to scale down its business activities as of the end of this month. A wholly owned supporting operation of Mitsubishi, recognised as the company's official tuner, Ralliart also provided Mitsubishi with assistance in various forms of motorsport, including the World Rally Championship, for more than 25 years.

In a letter on the company's website, president Masao Taguchi said: "Because of the sudden change of economy situation since the year before last, the business circumstance surrounding our company radically became worse and so, this time we have reached the conclusion that we Ralliart Inc, would scale down our business activities as of the end of March, 2010."
