DaimlerChrysler Japan Co. on Wednesday showed off the four cars that will launch the Dodge line in the Japanese market in June, part of the automaker's campaign to turn Dodge into a global brand.

The Chrysler unit, which has been struggling with falling sales in the United States, is trying to boost its overseas sales with a bigger lineup so it can rely less on the U.S. market. It introduced the Dodge brand in Europe last year.

"The growth of international markets, including Japan, is extremely important for the accomplishment of the goal of regaining profitability for the Chrysler group," Hans Tempel, president of DaimlerChrysler Japan, said at a media preview in Tokyo.
