GM and SAIC Motor to co-develop engines, transmissions

  • 20-Aug-2010 04:09 EDT

The new 6-speed dual-dry-clutch automatic being co-developed by GM and SAIC will be used with a new family of 1.0 to 1.5-L direct-injected, turbocharged engines also under development by the companies.

General Motors Co. and SAIC Motor Corp. Ltd. are expanding their partnership to develop a new small-displacement gasoline engine family and an advanced front-drive automatic transmission. The agreement, signed in Shanghai by GM Vice Chairman of Global Product Operations Tom Stephens and SAIC President Chen Hong, expands GM and SAIC’s relationship into powertrain development. 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 dual-dry-clutch transmission will provide up to a 10% improvement in fuel economy over existing conventional six-speed automatic transmissions, the companies claim, with improved shift quality. The companies said the new engine and transmission technologies, when combined, can provide up to 20% improvement in CO2 emissions, compared to comparable powertrains made in China today.
