New GM Ecotec Engines Coming, 'Quieter' than Ford EcoBoost
General Motors is responding to the popular Ford EcoBoost engines will an onslaught of its own new powertrains. GM dubs its new suite of engines "Ecotec," and plans to produce 11 variants in total. The engines will also have similar displacements to rival Ford, with a 1.0-liter turbocharged Ecotec three-cylinder engine being especially noteworthy. Ford has seen global success with its 1.0-liter turbocharged EcoBoost engine in the Ford Fiesta, and it's possible GM's response could first make its way into the Chevrolet Sonic, though that has not been confirmed. In a new Automotive News report, GM says the Ecotec engines will offer more refinement than models from Ford or Volkswagen, and will be as much as three decibels quieter than the EcoBoost engine, too. "From the outset, the noise and vibration requirements for the new Ecotec family were targeted at class leading," said Randy Guild, noise and vibration engineer for the global Ecotec engines. "Because we started with a clean-sheet design process, every component, from the cylinder block to the fuel injectors played a role in achieving segment-class refinement." Other engines such as a planned 1.5-liter turbocharged four-cylinder could be a good fit for the Chevrolet Cruze. GM says some variants will receive direct-injection for greater efficiency and turbochargers for added performance, and we suspect that this would be the case for U.S. models. The Ecotec engines will be built at GM plants in Michigan, China, Hungary, Mexico, and South Korea. Source: Automotive News
