General Motors is expected to unveil a major expansion for its Spring Hill plant Tuesday that could finally bring the long-promised two additional vehicles to assembly lines in Middle Tennessee, which analysts said Monday would most likely be a pair of premium midsize crossovers -- one each from Buick and Cadillac.
If the automaker holds to its earlier pledge made when the plant re-opened, the expansion should bring an additional investment of about $358 million and could double employment at the plant, which now has 2,002 workers.
GM promised the United Auto Workers in summer 2011 that it would reopen the shuttered assembly line with one new vehicle in 2012, then add two more midsize models sometime in 2014. The first model, the four-cylinder version of the Chevrolet Equinox, arrived last summer, restarting the assembly line that had been shuttered when production of the Chevrolet Traverse large crossover was moved to Michigan in late 2009.
