General Motors is making its biggest engine plant investment ever—$888 million for its Tonawanda Propulsion facility in Buffalo, New York. The goal is to build the next generation of V-8 engines for full-size trucks and SUVs starting in 2027.

Thanks to updated combustion and thermal systems, these new engines are expected to deliver stronger performance, better fuel economy, and lower emissions. GM says the move reflects its commitment to American manufacturing and keeping up with strong demand for its truck and SUV lineup.
“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,” said GM Chair and CEO Mary Barra.
Tonawanda will be the second GM plant to produce the new V-8s, following a $500 million investment in the Flint Engine plant announced last year. While preparing for the next-gen engines, Tonawanda will continue making the current fifth-generation V-8s.
The investment includes new machinery, tooling, and facility upgrades. It will support 870 jobs at the plant, including 177 at-risk roles. New York State is offering up to $16.96 million in tax credits to support the project.
“This investment marks an exciting new chapter for our plant,” said Plant Director Tara Wasik. “We’re proud to continue supporting Western New York and to deliver world-class propulsion systems to our customers.”
