Diamond-Star Motors (commonly abbreviated to DSM) was an automobile-manufacturing joint venture between the Chrysler Corporation and Mitsubishi Motors Corporation (MMC). The name came from the parent companies' respective logos: three diamonds (Mitsubishi) and a pentastar (Chrysler). Diamond-Star Motors was officially renamed Mitsubishi Motor Manufacturing of America, Inc. (MMMA) in 1995, four years after Mitsubishi took sole control of the plant, and since 2002 its official title has been Mitsubishi Motors North America, Inc. (MMNA) Manufacturing Division.
