GM recently announced that it was investing $918 million into four of its U.S.-based production facilities, $55 million of which is earmarked for the GM Defiance plant in Defiance, Ohio.
The $55 million investment includes $47 million to support the production of a variety of block castings for use in future GM V8 engine programs, as well as $8 million to build a casting development cell to support future EV strategies.
The GM Defiance plant in Ohio is an aluminum foundry and machining center that produces inline four-cylinder, V6, V8 cylinder blocks and inline four-cylinder head castings. These components are used in a variety of different GM models and brands, including Buick, Cadillac, Chevy, and GMC.
The facility is located at 26427 State Route 281 in Defiance, and spans some 1.9 million square feet. Initially opening in 1948, the GM Defiance facility currently employs roughly 530 workers (as of December 31st, 2022), who are represented by UAW Local 211. GM has invested more than $187 million into the facility since 2013.
The $55 million slated for the GM Defiance plant in Ohio is part of a broader $918 million investment that also includes $579 million for the GM Flint Engine plant in Michigan, $216 million for the GM Bay City GPS plant in Michigan, and the $68 million for the GM Rochester plant in New York. The new investments will support production of GM’s next-gen Small Block V8 at the GM Flint Engine facility, production of next-gen V8 components at the GM Bay City GPS facility, and the production of next-gen V8 components plus battery pack cooling lines for future GM EVs at the GM Rochester facility.
This latest round of investments brings GM’s U.S. manufacturing commitments to more than $37 billion since 2013, which also includes investments made through the Ultium Cells LLC joint venture with LG Energy.
