The $4 billion investment also includes expansion of the Fairfax Assembly Plant in Kansas City, Kansas, and Spring Hill Manufacturing in Spring Hill, Tennessee. GM says the investment will allow the automaker to produce more than 2 million vehicles annually in the U.S.

General Motors says that moving production of the Escalade to a site in Michigan will allow the Arlington plant — a huge employer in DFW — to make more of other vehicles.

GM produces the Cadillac Escalade at Arlington Assembly in Texas and both the GMC Sierra and Chevrolet Silverado are made at Fort Wayne Assembly in Indiana. GM said the truck production slated to begin at Orion in 2027 will be in addition to truck production in Fort Wayne.
