The automaker says it will build a 400,000-square-foot building next to the Lansing Grand River plant to assemble parts and put them in the right order for manufacturing.
The factory already employs more than 1,500 hourly and salaried workers who make the Cadillac ATS and CTS luxury sports sedans. It also will make the next generation Chevrolet Camaro in 2015.
GM says the new logistics center will make the factory more efficient and cut transportation costs. The building is expected to open by the end of next year.
The company says it's not sure yet how many new workers will be hired and how many would be recalled from layoffs.
