General Motors is shutting down its Brownstown Battery Assembly plant located south of Detroit. The facility was responsible for assembling battery packs for the Cadillac Celestiq, as well as battery packs and electric drive units for the Chevrolet Corvette E-Ray plug-in hybrid.
A company spokesperson stated that the closure is not linked to GM’s broader electric vehicle strategy. The decision follows the expiration of the lease agreement for the site. The automaker plans to relocate both the workforce and the production operations to other facilities, though specific locations remain undisclosed.
Despite the closure, GM continues its work in the electric vehicle sector, producing models such as the Chevrolet Silverado EV and the Chevrolet Bolt. The company is also investing $900 million in a new facility aimed at accelerating the commercialization of battery technologies.
The firm is currently researching alternative battery chemistries, including sodium-ion and lithium-manganese-rich options. These efforts persist even as the company adjusts its public stance on electrification following the repeal of federal incentives for electric vehicle production and sales.
