Posted on 19 August 2010. Tags: GM, SAIC

General Motors and SAIC Motor Corp are expanding their partnership to develop a new small-displacement gasoline engine family and an advanced transmission.

The new small gasoline engine, which will be offered in displacements from 1.0 liters to 1.5 liters. Its compact, lightweight design combines direct injection and turbocharging. 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 incorporate the latest innovations for improving fuel economy and performance. The transmission alone will provide upward of 10 percent improvement in fuel economy over today’s conventional six-speed automatic transmissions. The co-developed 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.

When combined, these technologies can provide up to 20 percent improvement in fuel consumption, compared to engines and automatic transmissions in production in China today.
