General Motors will invest $200M into its Global Powertrain Engineering Headquarters to build a new 138,000 sq.-ft. test wing, which is expected to be completed during the second half of 2014. The plan is part of GM’s previously announced commitment to invest $1.5B in its North American facilities in 2013. When the moves are complete, GM will have added approximately 400 jobs to the Pontiac campus. Under the expansion plan, engineering development work currently being done at leased facilities in Wixom, Mich.; Castleton, Ind. and Torrance, Calif., will move to Pontiac. Also, GM R&D’s Propulsion Systems Research lab in Warren, Mich. will relocate to the Pontiac campus. GM previously announced that work being performed at its hydrogen fuel cell facility in Honeoye Falls, N.Y., would be consolidated in Pontiac in mid-2013. In addition, the Performance Build Center, currently located at the Wixom facility, will move to GM’s Chevrolet Corvette assembly plant in Bowling Green, Ky., by the first quarter of 2014.
