GM to close Detroit Brownstown battery plant by summer 2026 as it shifts focus to petrol vehicles
By Eve
General Motors will decommission its 480,000 square foot Brownstown Battery Assembly facility in Detroit by next summer when the lease ends, moving production to other nearby GM sites. The plant, opened in 2009, currently manufactures high voltage batteries for the Cadillac Celestiq EV and Chevrolet Corvette E-Ray, plus drive units for the hybrid sports car. The closure forms part of GM's broader manufacturing shift that now prioritises petrol vehicles as the automaker absorbs billions of dollars in losses from its powertrain strategy changes.
Why it matters
The closure signals a major US automaker scaling back dedicated EV battery manufacturing infrastructure, potentially affecting component supply chains and procurement strategies for electrification projects. GM's pivot towards petrol production amid heavy EV losses may influence how fleet operators and charging infrastructure developers assess long term vehicle electrification commitments from traditional manufacturers.

Blue Energy Motors joins government PARIVARTAN scheme to supply electric heavy-duty trucks in Delhi-NCR
Blue Energy Motors has signed a Memorandum of Understanding with India's Ministry of Road Transport and Highways to participate in the PARIVARTAN Scheme, which offers financial incentives and tax concessions to fleet operators replacing aging, high-emission trucks and buses with zero-emission electric models across the Delhi-National Capital Region. The commercial vehicle maker will supply electric heavy-duty trucks to logistics providers transitioning away from fossil fuels under the programme.
Why it matters
The scheme creates a direct procurement pathway for electric truck suppliers targeting fleet operators in one of India's largest logistics corridors, with government-backed financial support lowering the barrier to heavy-duty EV adoption. For charging infrastructure providers, the programme signals growing demand for depot and en-route charging solutions capable of serving commercial electric trucks in the NCR.
Ultraviolette launches X-47 Venom electric motorcycle with 11 kWh battery and 343 km range at Rs 2.65 lakh
