GM's Detroit-Hamtramck plant was opened in February 1985. Cadillac K-body production was consolidated there in the 1990s. The Detroit-Hamtramck Assembly later received the contract for the production of Chevrolet Volt, which uses the Delta II/Voltec body. On April 21, 2010, GM announced it would invest $121 million into the Detroit/Hamtramck factory to ensure GM could keep up with the demand for the next generation Chevrolet Malibu. In May 2011, GM announced it would invest $69 million in the plant for the Chevrolet Impala. In 2013, production of the Cadillac ELR (a Cadillac equivalent of the Chevrolet Volt) began, followed two years later by production of the Cadillac CT6 and then the third-generation Buick LaCrosse.
