General Motors (GM) will invest $200m to construct a new test wing in its Global Powertrain Engineering Headquarters located at Pontiac in Michigan, US.
The new test wing, which is expected to complete in second half of 2014, will have a footprint of 138,000sqft and will combine the works being done at four other locations.
GM Global Engine Engineering vice president Sam Winegarden said: "These moves will help our entire Powertrain team work more effectively across the organization to develop the powertrain technologies we need to build the world's best vehicles for our customers around the world."
The expansion is a part of company plan to invest $1.5bn in its North American facilities in 2013.
The expansion plan will combine the facilities including the facilities in Wixom, Castleton, Torrance, and GM R&D's Propulsion Systems Research lab in Warren, while integrating the hydrogen fuel cell facility in Honeoye Falls, New York.
