Both engines are developed by General Motors in Europe and rely on all kinds of technologies aimed at reducing fuel consumption. For example, the Dynamic Variable Valve Timing (DVVT) and a Variable Intake Manifold (VIM) were especially introduced to provide high torque at low rpm and high horsepower per liter, with the 1.6-liter unit developing 54 kW/L of power, while the 1.8-liter engine produces 58 kW/L of power.
"The introduction of the new Ecotec engines is an example of our commitment to share our company’s latest technology with our joint ventures in order to ensure that GM products sold locally are as efficient as possible," said Kevin Wale, President and Managing Director of the GM China Group. "Our goal is to make all of our products and powertrains leaders in their class in fuel efficiency and emissions."
General Motors says the two new engines will be installed on models produced by Shanghai GM and sold in China but specific details on the cars likely to get these powerplants were actually not provided. However, Shanghai GM probably has some enthusiastic plans when it comes to the new Ecotec engines as China has now become one of the largest auto markets in the worlds.
Furthermore, Shanghai GM Dong Yue Automotive Powertrain, a joint venture between GM China, SAIC and Shanghai GM, which produces engines for Chevrolet and Buick models, has an estimated annual capacity of 660,000 engines, which gives us a hint that the Chinese division of GM will rely quite a lot on the new engines.
