GM Powertrain Evolution
GM Powertrain traces its history to the myriad of automotive companies that combined to form GM in 1908. These companies included: Chevrolet, Pontiac, Buick, Oldsmobile and Cadillac. For many decades, each division produced its own engines and transmissions. In time, it became evident that efficiency improvements could be made with increased administrative and manufacturing cooperation between all divisions. The consolidation began in 1983, with the assignment of the Toledo, Ohio Chevrolet and the Windsor, Ontario GM of Canada transmission plants to the Hydra-Matic division. The "marriage" of the Hydra-Matic and GM Engine divisions in 1990, resulted in GM Powertrain. The subsequent addition of Central Foundry Division and Advance Engineering Staff in 1991, elevated Powertrain to corporate group status. In 1997, the formation of a GM global powertrain organization was announced, encompassing all of GM's powertrain engineering and manufacturing activities outside of North America. In 2010 Powertrain and the vehicle organization were joined, creating Global Product Operations.
