General Motors is overhauling its compact car engines with new three- and four-cylinder powerplants that will span into at least 27 models in the next three years.
Three new gasoline Ecotec engines will be available: a 1.5-liter four-cylinder with 113 horsepower and 108 lb-ft of torque, a 1.4-liter turbocharged four-cylinder with 148 horses and 173 lb-ft, and a 1.0-liter turbocharged three-cylinder engine starting at 75 horsepower and 70 lb-ft of twist. GM will produce 11 variants of these three powerplants. Most feature direct injection, variable valve timing, and variable air intake; and some will be able to run on natural gas, or liquefied petroleum gas, depending on the market. While we don’t expect any of those alternative-fuel versions to make it here, GM said it could adapt them to hybrid powertrains.
The 1.4-liter turbo upgrades the current 138-hp engine that’s optional on the Chevrolet Cruze and Sonic models, and China will see it first in the next-generation Cruze later this year. In Geneva, GM introduced two versions of a 1.0-liter turbocharged three-cylinder for the latest Opel Adam, a spiffy European subcompact. Both states of tune develop 122 lb-ft of torque, but shoppers can choose between 90 horsepower and 115.
