GM to Invest $888 Million in Tonawanda Propulsion Plant to Build Next-Gen V-8 Engines

General Motors (GM) has announced a major $888 million investment in its Tonawanda Propulsion plant in New York to support the production of its sixth-generation V-8 engines. The move marks a significant step in GM’s continued investment in American manufacturing and reinforces its commitment to innovation, performance, and sustainability.

The new generation of V-8 engines will power GM’s full-size trucks and SUVs, offering enhanced performance while improving fuel economy and reducing emissions. These gains will be driven by advancements in combustion and thermal management technologies, underscoring GM’s focus on delivering cleaner and more efficient propulsion systems.

“Our significant investments in GM’s Tonawanda Propulsion plant show our commitment to strengthening American manufacturing and supporting jobs in the USA,” said Mary Barra, GM Chair and CEO. “This announcement builds on our strategy to lead in both traditional and next-generation propulsion technologies.”

The Tonawanda facility will receive upgrades including new machinery, tooling, and facility renovations to support production of the new engines. While preparing for the launch of the sixth-generation V-8 in 2027, the plant will continue to produce GM’s fifth-generation engines, ensuring a seamless transition and uninterrupted support for current vehicle lines.

“This investment marks an exciting new chapter for our plant,” said Tara Wasik, Plant Director at Tonawanda. “For generations, our team has demonstrated its commitment to manufacturing excellence, and we’re proud to help bring this next-generation V-8 engine to life.”

This announcement makes Tonawanda the second GM propulsion facility designated for sixth-generation V-8 engine production. In January 2023, GM committed $500 million to its Flint Engine plant — the largest single investment in an engine facility in company history.

Over the past 15 years, GM has made a series of strategic investments in its U.S. manufacturing footprint, balancing its long-term EV goals with a continued focus on refining and advancing internal combustion engine technologies.

The Tonawanda investment underscores GM’s dual-track approach: developing high-performance, efficient combustion engines alongside a growing electric vehicle portfolio, ensuring that customers across all segments continue to have compelling options for years to come.
