DETROIT—General Motors Co. is planning to invest $2 billion over the coming two years to convert part of its assembly plant in Spring Hill, Tenn., to electric vehicle production, starting with the Cadillac Lyriq.
GM also announced more than $150 million in investments in five Michigan plants related to production of the GMC Acadia, heavy-duty pickups, 10-speed transmissions and autonomous test vehicles.
Spring Hill will become GM's third EV plant. It will continue building the gasoline-powered Cadillac XT5 and XT6, but production of the Acadia will move to Lansing, Mich.
The $2 billion investment will expand the Tennessee plant's paint and body shops and comprehensive upgrades for general assembly, such as new machines, conveyors, controls and tooling. The renovation will begin immediately, GM said. Spring Hill is GM's largest plant in North America.
Over the last year and a half, GM has pledged more than $4.5 billion at three U.S. plants for EV-related production, including $2.2 billion at its plant in Detroit that it's now calling "Factory Zero."
Production on the GMC Hummer EV pickup is slated to begin at the Detroit plant in late 2021, followed by the Cruise Origin, a self-driving shuttle.
GM also will spend $3.5 million at a Chevy Bolt plant in Orion Township, Mich., and $750,000 at a battery plant in Brownstown Township, Mich., for production of the Cruise AV, a self-driving test vehicle.
"We are committed to investing in the U.S., our employees and our communities," GM CEO Mary Barra said in a statement. "These investments underscore the success of our vehicles today, and our vision of an all-electric future."
