General Motors will increase to $350 million investment in new vehicles to be produced at its Spring Hill, Tennessee, assembly plant. The additional investment adds $167 million to a previously announced $183 million expansion project and is expected to create or retain about 1,800 jobs.

The company said an additional $40 million will be added to the earlier announced $183 million investment to support a future mid-size vehicle program, bringing the new total investment to $223 million. This program is expected to create or retain approximately 1,000 jobs.

In addition, a second mid-size vehicle program with an investment of $127 million that will create or retain approximately 800 jobs. The new programs will add to existing manufacturing operations at the site that include vehicle assembly, stamping, engine and component parts production.

“Today’s announcement recognizes the commitment of Spring Hill employees and leadership," said Mark Reuss, president, GM North America. “As a team, they draw upon the plant's unique heritage and dedicated workforce to deliver top quality for our customers.”

Located 40 miles south of Nashville, GM Spring Hill Manufacturing operates as a flexible-assembly plant, capable of building a variety of products on a range of platforms. The facility is designed to supplement production for plants being retooled for new products or add production to meet sales spikes in real time.

Chevrolet Equinox production began at the site in the third quarter of 2012 to meet growing consumer demand and support GM’s Canada operations. GM Spring Hill Manufacturing, home to the former Saturn brand from 1990 to 2007, operates as a fully integrated complex.

“I would like to thank General Motors for its confidence that the highly skilled members of United Auto Workers Local 1853 can successfully build mid-size vehicles with high quality here at Spring Hill,” said UAW Vice President Joe Ashton, who directs the union’s GM Department. “The hard work and dedication of our members once again proves that we can competitively manufacture vehicles for the future right here in Tennessee.”
