GM plans $2 billion investment to build electric vehicles in Tennessee

General Motors Co said on Tuesday it will invest $2 billion to convert its Spring Hill, Tennessee, factory to produce electric vehicles, starting with the new Cadillac Lyriq, alongside existing combustion-engine Cadillacs.

Spring Hill will be GM's third US 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 Auto Forecast 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 its truck plant in Flint, Michigan, to increase production of the Chevrolet Silverado and GMC Sierra heavy-duty pickups.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 in addition to the Lyriq.
