NUMMI

New United Motor Manufacturing, Inc. (NUMMI) was an automobile manufacturing company in Fremont, California, jointly owned by General Motors and Toyota that opened in 1984 and closed in 2010. On October 27, 2010, its former plant reopened as a 100% Tesla Motors-owned production facility, known as the Tesla Factory. The plant is located in the East Industrial area of Fremont between Interstate 880 and Interstate 680.OverviewNUMMI was established at the former General Motors Fremont Assembly site that had been closed two years earlier in 1982 (GM plant since 1962). GM and Toyota reopened the factory as a joint venture in 1984 to manufacture vehicles to be sold under both brands.GM saw the joint venture as an opportunity to learn about lean manufacturing from the Japanese company, while Toyota gained its first manufacturing base in North America and a chance to implement its Taylorism-inspired production system in an American labor environment, avoiding possible import restrictions. GM employees went to Toyota's Takaoka plant in Japan and improved production at NUMMI, Spring Hill and other sites, particularly after Jack Smith spread the program.
