Spring Hill, Tennessee – General Motors is investing US$61 million to restart its idled Spring Hill assembly plant to supplement Canadian production of the Chevrolet Equinox.

The Spring Hill facility, originally a Saturn plant, will be one of the world’s most flexible, capable of building any GM car or crossover based on customer demand or manufacturing need.

Production of the Equinox is expected to begin in the second half of 2012. GM said that the model is so popular that production has increased three times since it was first built in 2009, and U.S. sales were up 18 per cent in October. Equinox production at GM’s plant in Ingersoll, Ontario was recently supplemented by the Oshawa, Ontario plant.

The company will also make a second investment of $183 million for future midsized vehicles to built in the Tennessee plant. The facility’s future role was part of negotiations with the United Auto Workers Union (UAW) for a four-year national labour agreement ratified in October.

Spring Hill built Saturns from 1990 to 2007 and the Chevrolet Traverse into 2009. Its powertrain and stamping operations are still operating, and GM has invested $515 into its engine operations over the last 14 months for current and next-generation four-cylinder engine production.
