General Motors (GM) is planning to invest $888 million in its Tonawanda Propulsion plant in Buffalo, New York, as part of boosting engine production in the country, the company said on May 27.
The investment would support the production of the sixth-generation V-8 gasoline engines used in SUVs and full-size trucks.
The latest funding is the “largest single investment the company has ever made in an engine plant and makes Tonawanda the second GM propulsion plant to produce this new generation of engines.”
The investment includes the installation of new machinery and tools as well as renovations to the facility. The site will continue to produce fifth-generation V-8 engines while the facility prepares to kick-start sixth-generation production in 2027.
GM CEO Mary Barra said the company’s significant investments in the Tonawanda Propulsion plant “show our commitment to strengthening American manufacturing and supporting jobs in the U.S.”
“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.”
Secretary of Transportation Sean Duffy called the project “another BIG win in @POTUS’ fight to bring back domestic manufacturing,” according to a May 28 X post. “These investments will ensure America remains a world leader in transportation.”
Multiple other automakers have announced manufacturing investments in the United States under the Trump administration.
Made in America
Earlier this month, GM said it intended to focus more on domestic production amid the Trump administration’s tariff policies.GM Chief Financial Officer Paul Jacobson said the company planned on offsetting at least 30 percent of expected costs from tariffs through measures such as cost reductions and increased sourcing from the United States.
GM’s decision to scale down EV ambitions comes at a time when the industry is facing lower sales.
Meanwhile, Republicans have introduced the One Big Beautiful Bill Act, which includes a provision to eliminate the $7,500 in federal incentives currently being offered to “clean new vehicles.”
Commodity Insights analyst Suzanna Massingue predicted an “overall negative impact on national EV sales” once the incentives are rolled back. This would affect all EV makers, including GM.
The House of Representatives passed the bill on May 22. It now heads to the Senate.
