- General Motors announced that it is investing roughly $505 million into the St. Catharines Propulsion plant in Canada to build its next-generation V-8.
- The new small-block engines will also be built at the Tonawanda Propulsion factory in Buffalo, New York, and at Flint Engine Operations in Flint, Michigan.
- The sixth-generation V-8 will first appear in the 2027 Chevy Silverado, expected to be revealed later this year.
General Motors is committed to V-8s. After announcing an $888 million investment in the Tonawanda Propulsion plant to build its next-generation small-block engine last year, the automotive giant is now deepening its dedication to eight cylinders. Today, GM Canada announced a CAD $691 million (USD $505 million) investment in the St. Catharines Propulsion plant in Ontario, Canada, to build the new sixth-generation V-8 for GM's full-size trucks and SUVs.
GM says the factory is already getting ready for its new duties, with equipment arriving now. Still, the St. Catharines site will continue to build the fifth-generation V-8 while retooling for the new engine. Along with the Tonawanda and St. Catharines factories, GM also plans to build the sixth-gen V-8s at Flint Engine Operations in Michigan, which received a $500 million injection in 2023.
GM says this vast investment in engine manufacturing will allow the company to meet the strong demand for its full-size trucks. While GM doesn't break out sales by engine configuration, it sold 577,434 gas-powered Chevy Silverados and 348,222 gas-powered GMC Sierras in the U.S. last year, and a large percentage likely featured V-8s. That also doesn't account for the over 315,000 full-size SUVs GM sold last year across three brands, with V-8s accounting for the majority of those sales as well.
The new V-8 engine will appear in the next-generation 2027 Chevy Silverado and GMC Sierra, as well as future versions of the Chevy Tahoe, Chevy Suburban, GMC Yukon, and Cadillac Escalade. GM is promising better performance alongside improved fuel efficiency.
GM has also invested CAD $343 million into the Oshawa Assembly site in Ontario, Canada, which currently produces the Silverado 1500 and Silverado HD, to build the next-generation trucks. In the announcement, GM said that it is still weighing future opportunities for the CAMI Assembly plant in Ingersoll, Ontario, which has been idle since October 21, 2025, after GM discontinued the electric Chevy BrightDrop van, which sold only 4971 units in the U.S. in 2025.
