Our History

GM has been helping to power the machines that shape our world for over a century—and this continues to endure today, with GM engines powering our cities, our transportation, and our way of life.
GM Powertrain OEM Sales traces its history to the myriad automotive companies that combined to form GM in 1908. The original companies included: Chevrolet, Pontiac, Buick, Oldsmobile, and Cadillac. For many decades, each division produced its own engines and transmissions. In time, efficiency improvements were made through increased cooperation among divisions. Currently, the GM Powertrain OEM Sales team is supported by teams around the world.
