Diamond-Star Motors
former automobile manufacturer
Mitsubishi Motors North America, Inc. Manufacturing Division (originally, Diamond-Star Motors) was an automobile-manufacturing joint venture between the Chrysler Corporation and Mitsubishi Motors. 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 from 2002 to 2016 its official name had been "Mitsubishi Motors North America", Inc.", and "Manufacturing Division".
In the automotive enthusiast community, DSM, especially used in the singular (e.g. a DSM) generally refers to the original first- and second-generation Mitsubishi Eclipse, Eagle Talon, and Plymouth Laser, which all shared the same Diamond-Star Motors vehicle platform.
In January 2017, Rivian acquired the plant and its manufacturing contents for $16 million, as its primary North American manufacturing facility.
History
Background
The origins of Diamond-Star Motors can be traced back to 1970 when Chrysler took a 15 percent stake in Mitsubishi Motors, as part of MMC's strategy of expansion through alliances with foreign partners. The U.S. company began distributing Mitsubishis as Chrysler-, Dodge-, and Plymouth-branded captive imports (e.g. Dodge Colt), a successful venture as the compact cars met consumer demand for smaller and more fuel-efficient vehicles in the 1970s, filling a gap at the bottom of the Chrysler group's range.
