General Motors has unveiled a new generation of their Ecotec engine family, whose 11 three- and four-pot powerplants will find a home under the bonnets of 27 models by 2017.
Automotive News reports the new clean-sheet engines range from a turbocharged 1-liter I3, to a 1.5-liter turbo-four, feature modular design for efficient assembly, consist of aluminium heads and blocks, and include VVT, dual overhead cams with four valves per cylinder, and water-cooled exhaust manifolds among other offerings. Power in the family ranges from 75 horses/70 lb-ft of torque, to 165 horsepower and 184 lb-ft.
The first of the new engines, the aforementioned I3, is already under production, and will debut under the hood of the Opel Adam later this spring, while the 2015 Cruze will come with a turbocharged 1.4-liter and a naturally aspirated 1.5-liter for the Chinese market. No word on when the Ecotec engines will debut in North America, however, let alone which vehicles will receive them.
GM expects annual volume to reach 2.5 million units by 2017 once all five factories responsible for their production are in full swing. The factories are located in Michigan, Mexico, China, Hungary and South Korea.
