GM developed some expertise in electric motor manufacturing with a pilot factory in Wixom, Mich. Before launching manufacturing at the Baltimore plant, workers completed training on the operation of the machines used to configure and manufacture the electric motor and drive units.
The Baltimore plant is GM's exclusive manufacturer of A1000 transmissions for heavy duty pickup trucks and electric motors and drivetrains for the Chevrolet Spark EV. This factory has been zero-landfill since 2007, recycling 100% of its waste. It also has a 1.2 MW roof mounted solar array, that was installed in May 2011.
A new facility was built on the grounds of the Baltimore plant was built explicitly for electric motor manufacturing. This business was formerly operated in Mexico, and has been brought back to the U.S.
