General Motors as officially announced output figures for its new 1.0-liter three-cylinder turbocharged mill.
Bound for the Opel Adam, GM says the little three-banger is more powerful than the 1.6-liter four-cylinder currently found in that car. The engines are built in the Detroit giant’s Flint Engine Operations plant in Michigan. Ford’s 2014 Fiesta will use a turbocharged 1.0-liter three-cylinder engine from the company’s EcoBoost line, raising questions about possible plans from GM to follow suit with its U.S. sub-compacts.
GM Spokesperson Annalisa Esposito-Bluhm said that plans to implement the turbo 1.0-liter engine in either the Spark or Sonic don’t exist yet.
The Chevrolet Spark currently uses a 1.2-liter inline four-cylinder engine that only makes 84 hp and 83 lb-ft of torque. Lending a smaller, more powerful engine into its powertrain seems like a no-brainer. For 2014, the Spark gains a continuously-variable transmission in place of its previous torque-converter automatic and ditching 0.2 liters of displacement would presumably further enhance those gains. It would also probably make the Spark a hoot to drive.
Still, Esposito-Bluhm said GM is keeping an eye on Ford. When asked if GM could be ready with a fast answer to the EcoBoost Fiesta, she said testing and calibration would be required for the smaller engine but highlighted the 2014 Malibu’s rapid transformation to alter products quickly “when necessary.” The Malibu was redesigned for
