GM to Invest $22 Million in Spring Hill for Big V8 Engines

The Spring Hill engine plant builds four- and eight-cylinder engines.

General Motors is investing $22 million at its Spring Hill, Tennessee, manufacturing complex to enable the engine plant to build big 6.2-liter V8 engines with cylinder deactivation. With the announcement, GM says it has invested more than $2 billion in the Tennessee complex since 2010.

GM’s so-called Dynamic Fuel Management technology is the industry’s first cylinder deactivation technology that enables the fuel thirsty big engines to operate in 17 different cylinder patterns to optimize performance. DFM enables only the cylinders needed to deliver the power that an engine control computer thinks is needed.

“This investment will enable our Spring Hill team to continue building our award-winning engines enhanced with technology that will improve fuel efficiency and performance for our customers,” said GM Chairman and CEO Mary Barra during a visit to the plant to meet with employees and community leaders to celebrate the new Cadillac XT6.

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.

The Spring Hill complex opened in 1990 as a Saturn plant and currently employs about 3,800 people.

GM in Tennessee has with more than 4,000 employees working in the state. In addition to the Spring Hill complex, GM has a parts distribution center in Memphis. Tennessee is home to more than 200 suppliers and GM spends more than $700 million annually with those suppliers. GM currently has 78 independently owned dealerships across the state that employ about 4,800 people. Nearly 11,000 GM retirees currently call Tennessee home.
