General Motors developed 11 small-displacement EcoTec engines to power many of the automaker's highest-volume small cars and compact crossovers including the next-generation Chevrolet Cruze specifically tailored to China.

The first vehicles receiving the new gasoline engines include the 2015 Chevrolet Cruze, which launches later this year, and the Open Adam for the European market.

The new EcoTec engines include three- and four-cylinder varients ranging from 1.0L to 1.5L displacement, including turbocharged versions. The engines should generate from 75 to 165 horsepower and between 70 and 184 lb.-ft. or torque, according to GM.

The engine architecture has been designed to support gasoline-electric hybrid powertrains and alternative fuels.

The first engines will include a 1.0L turbocharged three-cylinder powering the Opel Adam in Europe and a 1.5L four-cylinder for the Cruze in China. Cruze models with the 1.4L turbo engine sold in China will also get a new dual-clutch gearbox.
