General Motors is making its biggest-ever investment in an engine plant. Yup, in the wake of electrification, the American giant shows commitment to building internal combustion engines. But not just any kind, they will build V8s!

The $888 million investment in GM’s Tonawanda Propulsion plant will support production of the automaker’s upcoming sixth-generation V8 engines. These engines will power GM’s full-size trucks and SUVs and are expected to deliver more performance while reducing emissions and improving fuel economy.

The Tonawanda plant, which has been in operation for 87 years, will now play a key role in GM’s long-term propulsion strategy. It becomes the second plant to build the new V-8s, following a previous $500 million investment into GM’s Flint Engine plant announced in early 2023.

This latest investment will fund new machinery, equipment, tooling, and facility renovations, all aimed at preparing Tonawanda for the future of internal combustion performance. Production of the new V-8s is scheduled to begin in 2027.

The sixth-generation V-8 will bring new combustion technologies and advanced thermal management to the table. GM says this will improve fuel efficiency while maintaining, or even exceeding, the raw power customers expect from its larger vehicles.

“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. We are grateful for the opportunity to continue supporting the Western New York community and are steadfast in our mission to deliver world-class propulsion systems to our customers.”

The plant, represented by UAW Local 774, will continue building the current fifth-generation V8s while ramping up for the new engine line. That means jobs are not only protected, they’re future-proofed.

GM Chair and CEO Mary Barra added that the investment reinforces the company’s commitment to American manufacturing. “GM’s Buffalo plant has been in operation for 87 years and is continuing to innovate the engines we build there to make them more fuel efficient and higher performing, which will help us deliver world-class trucks and SUVs to our customers for years to come.”

The move comes as GM balances its EV transition with continued demand for gas-powered trucks and SUVs. While the company is aggressively expanding its EV lineup, it remains committed to improving internal combustion technologies during the transition.

Tonawanda’s next-gen V-8 is a clear sign: GM’s future includes battery-electric powertrains, but it’s not abandoning the engine just yet. Not when there’s still innovation left to squeeze out of every cylinder.
