GM making investments at Tennessee and Michigan factories

General Motors announced Wednesday that it is spending $790 million to build a new high-efficiency engine at its plant in Tennessee, creating nearly 800 jobs.

The investment is the latest boost for the Spring Hill Manufacturing Plant, where vehicle production was idled during the Great Recession. Since 2010 GM has poured $2 billion into the plant facility 30 miles south of Nashville that makes two four-cylinder engines and the Cadillac XT5 midsize SUV. The plant will also begin producing the GMC Acadia later this spring.

"Today's announcement reinforces our absolute faith in this facility," said Arvin Jones, GM's North American manufacturing manager.
