GM Reveals Ecotec 1.0T and 1.3T Engines

SHANGHAI – General Motors today revealed its new-generation Ecotec 1.0T and 1.3T dual injection engines that are being launched in China. The turbocharged engines were developed as a global architecture with the support of GM’s worldwide manufacturing and supply chain networks. They will power Buick and Chevrolet models built and sold in the domestic market starting later this year.


“GM is integrating our unmatched global resources with our local capabilities to offer reliable, durable and efficient propulsion systems,” said Michael Carman, GM China Vice President of Global Propulsion Systems. “These new engines will offer a great ownership and driving experience to our customers across China.”

The new engines are leaders in performance and efficiency. The 1.0T engine generates maximum power of 92 kW/170 Nm, while the 1.3T engine produces maximum power of 120 kW/230 Nm. Fuel economy has been improved by up to 10 percent compared to the engines powering the popular Buick Excelle GT. This translates into combined fuel consumption of only 4.9 liters/100 km for the 1.0T engine and 5.8 liters/100 km for the 1.3T engine.

Representing a new architecture, the new-generation Ecotec 1.0T and 1.3T engines incorporate a series of cutting-edge driveline technologies. They are the first turbocharged engines to apply dual port injection, which optimizes combustion.

The engines have a compact aluminum structure and redesigned combustion chamber, further enhancing efficiency. Twelve core technologies have been adopted to significantly reduce structural noise and vibration. The innovative application of intelligent mechatronics supports precise control, green operation and high power.

To ensure the highest level of durability, 367 prototypes were put through nearly 6 million km of testing in different conditions, including high altitude, high temperature, extreme cold, high humidity and corrosive environments, and on varying road surfaces.

The new-generation Ecotec engines will be produced in GM’s world-class propulsion manufacturing facilities using digitized, automated and big data-controlled manufacturing processes and innovative technologies.

General Motors traces its roots back to 1908. GM has 10 joint ventures, two wholly owned foreign enterprises and more than 58,000 employees in China. GM and its joint ventures offer the broadest lineup of vehicles and brands among automakers in China. Passenger cars and commercial vehicles are sold under the Baojun, Buick, Cadillac, Chevrolet, Jiefang and Wuling brands. In 2016, GM delivered more than 3.8 million vehicles in China.
