The United States has had the sedan-only ninth-generation PS platform model since 2003, announced at the New York International Auto Show in April of that year, for the 2004 model year. Other markets did not see it till much later. One of the first markets outside North America to get it was the Republic of China, which launched the Galant Grunder in December 2004, with a (so far) unique front end. All new Galant engines come with new GDI or gasoline direct injection engines. Mitsubishi was the first car manufacturer to commercially use the GDI or stratified charge engine.

The Middle East and eastern Europe will likely source its Galants from the United States from 2006.

In Australia, starting in the 2006 model year, Mitsubishi are selling a modified version of the North American Galant as the 380, denoting its 3.8 L engine. The 380 is a successor to the Magna and the Verada large cars that also formed the basis for the North American Diamante. The 380 is a crucial car for Mitsubishi because this is the car that will determine the future of Mitsubishi's Australian manufacturing operations. However, sales have been poor and within 3 months of introducing the model in Australia, Mitsubishi Australia have announced that production will be decreased and 250 staff at its factory are being laid off. This is 15% of the factory staff.
