General Motors has announced plans to invest more than US$150m in its Saginaw Metal Casting Operations (SMCO) to support the production of the sixth generation of its V-8 engine blocks and heads used in full-size pickup trucks.
This commitment builds on the approximately US$5.5bn in investments GM made in 2025. In January 2023, the company announced a half-billion-dollar investment in its Flint Engine plant for production of the sixth generation of V-8 engines. The investment in SMCO, which includes includes new equipment and tooling, will support this work.
“This significant investment of over US$150m is a clear commitment to the plant and our people,” said John Lancaster, plant director, GM. “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.”
SMCO will continue to produce the fifth generation of GM’s V-8 engine blocks while the plant prepares for the next generation’s production start in 2027.
