Spring Hill will be GM's third U.S. electric vehicle factory, along with existing plants in Detroit and Orion Township, Michigan. The Tennessee plant was built in 1990 as the exclusive source for GM's now-defunct Saturn brand.
The Cadillac Lyriq crossover is slated to go into production in Spring Hill in late 2022, according to AutoForecast Solutions (AFS), which tracks industry production plans.
AFS said it expects some electric vehicle production will be announced at a later date for a factory in Mexico.
Among additional investments, GM on Tuesday said it will spend $32 million at a plant in Flint, Michigan, that builds the Chevrolet Silverado and GMC Sierra heavy-duty pickups.
GM shares were up 5.3% to $35.10 in midday trade.
GM will spend $100 million to shift production of the redesigned GMC Acadia crossover from Spring Hill to a plant near Lansing, Michigan.
Spring Hill will continue to build the gas-engine Cadillac XT5 and XT6 crossovers. The plant also will build other future electric vehicles.
The automaker's plans for investing in U.S. factories comes with two weeks left in the U.S. presidential election campaign. President Donald Trump and Democratic rival Joe Biden are competing for support from auto workers in Midwestern swing states.
