GM commits US$150m to Saginaw casting operations

General Motors has announced an investment of more than US$150m in its Saginaw Metal Casting Operations (SMCO) in Michigan, supporting production of the sixth generation of its V-8 engine blocks and cylinder heads for full-size pickup trucks. The commitment adds to approximately US$5.5bn in investments GM made across its US manufacturing network in 2025.

The funding covers new equipment and tooling at SMCO, which will continue producing the fifth generation of GM’s V-8 engine blocks while the facility prepares for sixth-generation production, set to begin in 2027. The third-oldest GM facility in the United States, SMCO employs more than 300 workers across three shifts.

The investment builds on a US$500m commitment GM announced in January 2023 for its Flint Engine plant, also targeting sixth-generation V-8 production. SMCO’s engine block and cylinder head work is designed to support that programme.

In a statement, John Lancaster, Plant Director, said: “This significant investment of over $150 million is a clear commitment to the plant and our people. By enabling the production of next-generation engine blocks and cylinder heads for full-size trucks, the plant is well-positioned for the future. This not only secures existing jobs but also strengthens the local economy, and ensures the plant continues to be an integral part of the automotive supply chain.”
