 DETROIT AP General Motors plans to spend 2 billion to convert its Spring Hill, Tennessee, assembly plant into a third U.S. site to build future electric vehicles. The Detroit automaker also says it will spend another 153 million to upgrade five Michigan factories for future vehicles. The company will build the Cadillac Lyriq, a small electric SUV, at the Spring Hill factory. Gasoline-powered Cadillac SUVs will continue to be built at the plant, and it will also get additional unspecified electric vehicles, GM said in prepared statement Tuesday. Were investing in U.S. manufacturing to ensure that GM can build the vehicles that customers love today as well as transition to an all-electric future, Gerald Johnson, GMs executive vice president of global manufacturing, said during an online announcement. We want to put everyone in an electric vehicle. The Lyriq is due in showrooms sometime late in 2022. GM also is expected to announce details of an all-electric GMC Hummer pickup truck this week. Theyre among 20 electric models the company plans to sell globally by 2023. GM already has announced that electric vehicles will be built at its plant in Orion Township, Michigan, and at the Detroit-Hamtramck plant, which straddles the border between the city of Detroit and the hamlet of Hamtramck. Currently the 7.9-million-square-foot Spring Hill facility employs about 3,400 hourly workers who make the Cadillac XT5 and XT6 gas-powered SUVs as well as a GMC SUV. The complex, which is GMs biggest in North America, also makes four engines that go into GM trucks and SUVs. The paint and body shops at Spring Hill will see major expansions, and the general assembly area will get new machinery, conveyors, controls and other equipment. Renovation of the plant...
