GM To Invest $55M At Defiance Facility For Engine And EV Castings Production

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.

GM is investing $55 million into the GM Defiance plant in Ohio.

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.

  1. Why is this a right turn from the EV crazies !!! Can it be they figured out the Electric grid can’t handle the mess from the EV’s. I’m betting on the world thinks that California will fall in the ocean. Then we all can go back to the norm. What other false rumors have they dumped on us. 😂🤣👀🎰

  2. Trucks and Big SUV sales with V8 engines give the necessary profit to fund the EV development. For all the people (myself included) who are buying these full-size trucks your actually helping push us towards EV’s in a roundabout way.

  3. Sorry, Mary but you have alot to learn about investing in the future of our environment. The .9billion would better serve humanity in areas like building Solar canopies over parking areas, Quantum batteries & Chargers, etc,etc. All offer return on investment, today & in our Future.

  4. GM Authority could do a better job selecting photos to accompany their articles. I am a retired GM manufacturing engineer. The first photo shows a truck engine on an ‘engine dress’ line from one of the 4 truck final vehicle assembly plants. (Silao, Fort Wayne, Flint, Oshawa). It has nothing to do with the Defiance Ohio casting plant. The second photo shows a scrap collection drum, not a very dignified view of a casting plant operation.

    But alas, the third actually shows a casting plant operation. They should have just shown the third picture only.

    1. I noticed the poor choice of photos also. You should consider using some experienced retirees as editors
