SHERIDAN, WYOMING – June 6, 2025 – General Motors is revving up its commitment to American manufacturing with a major $888 million investment in its Tonawanda Propulsion plant in Buffalo, New York, ushering in a new era of more powerful and fuel-efficient engines for its full-size trucks and SUVs.
This milestone marks the largest investment GM has ever made in an engine plant and reflects the company's long-term vision to improve performance while reducing emissions—something consumers will feel both on the road and at the pump.
A new generation of engines, a new level of performance
At the heart of this investment is GM’s upcoming sixth-generation V-8 engine, designed to deliver superior performance without compromising fuel economy. By introducing advanced combustion and thermal management innovations, these engines aim to provide:
- Increased horsepower and torque for everyday driving and towing
- Improved fuel efficiency, helping drivers save on gas
- Lower emissions for a cleaner ride
This move follows a $500 million investment in GM’s Flint Engine plant in 2023 and solidifies Tonawanda’s role as a key player in the company’s powertrain future.
Commitment to American jobs and communities
GM’s leadership made it clear that this investment is about more than just engines—it's about people and progress.
“Our significant investments in GM’s Tonawanda Propulsion plant show our commitment to strengthening American manufacturing and supporting jobs in the U.S.,” said Mary Barra, Chair and CEO. “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.”
In addition to new tools, equipment, and machinery, the investment will include facility upgrades that modernize the plant’s capabilities, setting the stage for long-term production success.
Local pride and a focus on the future
The team at Tonawanda is energized by the new chapter ahead. With production of the fifth-generation V-8 engines continuing as preparations begin for the new version, the plant is set to remain a cornerstone of GM’s propulsion strategy for years to come.
“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 steadfast in our mission to deliver world-class propulsion systems to our customers.”
The sixth-generation engines are scheduled to begin production in 2027, ensuring that GM’s popular truck and SUV models remain at the forefront of innovation and performance.
Bringing consumers the best of both worlds
As GM continues to invest in both gas-powered and electric vehicle technologies, drivers will have more options that fit their lifestyles—whether they’re loyal to traditional trucks or looking ahead to electric alternatives. GM’s brands, including Buick, Cadillac, Chevrolet, and GMC, remain focused on delivering quality, performance, and sustainability.
