AEM Tru-Time Adjustable Cam Gears The Mitsubishi Galant is an automobile manufactured by Mitsubishi Motors since 1969. The name was derived from the French word galant, meaning chivalrous.[1] There have been nine distinct generations, and cumulative sales now exceed five million.[2] It began as a compact sedan, but over the course of its life has evolved into a larger mid-size car. Initial production was based only in Japan, but since 1994 the American market has been served by vehicles assembled at the former Diamond-Star Motors (DSM) facility in Normal, Illinois.
