General Motors is investing $275 million in its Spring Hill manufacturing complex to support future vehicle production and continue its 2.7-liter engine program.
The investment includes $150 million for Spring Hill Assembly to prepare for the production of a future Cadillac vehicle with an internal combustion engine and $125 million for Spring Hill Global Propulsion Systems to refurbish equipment and extend production of the 2.7-liter turbo engine.
Company officials said the investment reflects GM’s long-term commitment to the Spring Hill facility and its workforce while strengthening the company’s manufacturing operations.
Once the new Cadillac model is added, Spring Hill Assembly will produce five vehicles, joining the Cadillac LYRIQ, LYRIQ-V, VISTIQ, next-generation XT5, and the Chevrolet Blazer, which is scheduled to begin production in 2027.
The investment in the propulsion plant will help continue production of the 2.7-liter turbo engine, which powers several Chevrolet and GMC trucks, including the Colorado, Canyon, Silverado, and Sierra.
GM said the announcement is part of a larger effort to strengthen U.S. manufacturing. The company expects to invest about $9 billion in its U.S. manufacturing operations this year, in addition to more than $7 billion in U.S. research and development.
The latest investment follows several major commitments to the Spring Hill campus in recent years, including a $2 billion investment in Spring Hill Assembly announced in 2020, a $2.3 billion battery plant announced with LG Energy Solution in 2021, and the addition of Chevrolet Blazer production announced in 2025.
