General Motors is investing $22 million at its Spring Hill, Tennessee, manufacturing complex to enable the engine plant to build 6.2L V-8 engines with GM’s advanced Dynamic Fuel Management technology. GM has now invested more than $2 billion in the Tennessee complex since 2010.

GM’s Dynamic Fuel Management technology is the industry’s first cylinder deactivation technology which enables the engines to operate in 17 different cylinder patterns to optimize performance. DFM enables only the cylinders needed to deliver the power a customer wants.

In addition to the new investment, GM is completing a previously announced $300 million investment at the complex for production of the all-new Cadillac XT6. Spring Hill will be adding more than 200 jobs for the all-new, three-row Cadillac crossover.

GM’s Spring Hill Manufacturing complex consists of a flexible vehicle assembly plant and an engine plant. On the vehicle side, the plant produces the GMC Acadia, Holden Acadia and Cadillac XT5. In addition, Cadillac just unveiled the all-new Cadillac XT6 and the plant will begin building the vehicle later this year. The engine plant builds four- and eight-cylinder engines.
