General Motors will invest $788.7 million in its Spring Hill Manufacturing Plant in Tennessee for a new "high-efficiency engine program," GM has announced.

The investment will create 792 jobs and retain 16 jobs. The complex will begin building small block V-8 engines by the end of 2016.

Construction will begin in May at the plant and will last several years. The Tennessee Valley Authority worked with government and company representatives in helping secure this investment announcement.

Spring Hill Manufacturing opened in 1990 and produced Saturn vehicles until March 2007. It produced the Chevrolet Traverse from September 2008 until November 2009, and the Chevrolet Equinox from September 2012 until October 2015.

Currently, the site operations consist of a flexible vehicle assembly plant producing the Cadillac XT5 and the GMC Acadia, an engine plant making 4-cylinder engines, a stamping plant, a body shop, a paint shop and two polymer injection molding operations. Engines and stampings are supplied to various GM assembly plants globally.
