General Motors is to rename its Powertrain division to GM Global Propulsion Systems.

The operation is collectively the group of more than 8,600 people, which designs, develops and engineers all propulsion-related products and controls for GM worldwide.

"The new name is another step on our journey to redefine transportation and mobility," said Global Product Development EVP, Mark Reuss.

"Global Propulsion Systems better conveys what we are developing and offering to our customers: a diverse line-up; ranging from high-tech 3-cylinder gasoline engines to fuel cells, V8 diesel engines to battery electric systems, and 6-, 7-, 8-, 9- and 10-speed, to continuously variable transmissions."

GM's expanding capabilities include the estimated more than 200 miles of range on a single charge on the all-electric Chevrolet Bolt EV (based on GM testing).

GM maintains it has also produced the highest non-hybrid passenger car fuel economy in the US market at an EPA-estimated highway 46mpg in the 2L diesel powered Chevrolet Cruze.

Nearly 50% of the Global Propulsion Systems engineering workforce is involved with alternative or electrified propulsion systems, while other technologies include products such as the 3.6L V6 with cylinder deactivation available in the Cadillac CT6.

"Gone are the days when a gasoline engine and a transmission designed independently meet a customer's expectations," said GM Global Propulsion Systems VP, Dan Nicholson.

"Today's customer is demanding unprecedented technology integration that requires unprecedented engineering and supplier partnerships.

"The diversity of our propulsion systems requires a name that reflects what we are already working on and delivering to our customers."

GM Global Propulsion Systems is responsible for all GM vehicle propulsion systems' design, development and validation, including engines, transmissions, electrification systems, fuel cell development and all associated control systems.

The Pontiac, Michigan, Global Propulsion Systems Engineering Centre is the flagship of GM's eight global powertrain engineering operations, which also include Brazil, Germany, Italy, India, China, Korea and Australia, collectively representing US$1.5bn in global investments in recent years, including joint ventures.
