Diamond-Star Motors, Automotive manufacturing plant in Normal, Illinois, US.
Diamond-Star Motors was an automotive manufacturing plant in Normal, Illinois that occupied a large industrial facility. The plant was designed as a joint venture to produce multiple vehicle models under different brand names for both parent companies.
The plant was founded in 1985 through a partnership between Chrysler Corporation and Mitsubishi Motors, bringing together their manufacturing expertise. This collaboration between an American and Japanese automaker marked an important moment in the automotive industry of that era.
The facility's name merged the symbols of both parent companies: Mitsubishi's three diamonds and Chrysler's pentastar. This connection was visible in every aspect of how the plant operated and presented itself.
The facility is no longer accessible to visitors as it ceased operations, and company information is difficult to find online today. The site remains in Normal, Illinois, though there is limited public access to historical details about its former operations.
Illinois secured the plant's location through a substantial incentive package that proved decisive in a competition between multiple states. This economic commitment demonstrates how much the region invested in attracting the manufacturer.
