GM and SAIC To Develop New Small-Displacement Gasoline Engine Family and Transmission; Combined Up To 20% Reduction in CO2 Emissions

General Motors Co. and SAIC Motor Corp. Ltd. (SAIC Motor) are expanding their partnership to develop a new small-displacement gasoline engine family and an advanced transmission. When combined, these technologies can provide up to a 20% improvement in CO2 emissions, compared to engines and automatic transmissions in production in China today.

The new small gasoline engine will be offered in displacements from 1.0 liters to 1.5 liters. Its compact, lightweight design combines direct injection and turbocharging, providing customers fuel efficiency and performance.

The engine will be used by GM and SAIC Motor in China and future vehicles worldwide, providing further fuel efficiency advances beyond traditional technologies.

Engineering and development of the new engine will be carried out jointly by GM and SAIC engineers in Detroit and at the Pan Asia Technical Automotive Center (PATAC), the automakers’ engineering and design joint venture in Shanghai.

The new front-wheel-drive transmission will feature dry, dual-clutch technology. It will provide shift comfort equal to a conventional fully automatic transmission, with superior quality, while reducing CO2 emissions. The transmission alone will provide upward of 10% improvement in fuel economy over today’s conventional six-speed automatic transmissions.

The agreement, signed today in Shanghai by GM Vice Chairman of Global Product Operations Tom Stephens and SAIC President Chen Hong, represents a significant milestone that expands GM and SAIC’s relationship into powertrain development.

The co-development of these new engines and transmissions builds on a strong history of innovation and collaboration between GM and SAIC Motor. Together, we will continue to quickly provide our customers leading-edge technologies that improve vehicle fuel efficiency and deliver robust performance.
