Production of GM’s 4-cylinder Ecotec engine surpassed 4 million units today at the company’s Spring Hill, Tennessee, plant just two years after the 3-million milestone was crossed.

The Ecotec powers GM vehicles such as the new 2015 Chevy Malibu Eco as well as the Chevy Equinox, Buick LaCrosse and GMC Terrain. Global vehicles such as the Chevy Captiva Sport in Mexico, Chevy Orlando in Korea and Opel Astra in Poland also get the engine.

In 2010 and 2012, WardsAuto named the Spring Hill-manufactured Ecotec engine one of the ‘10 Best Engines’ for North America. GM Spring Hill currently manufactures the Ecotec 2.0-liter turbocharged direct injection 4-cylinder engine, the Ecotec 2.4-liter direct injection 4-cylinder engine and Ecotec 2.5-liter direct injection engine.

“GM’s line of Ecotec engines continue to win awards and recognition from critics and consumers alike for their fuel efficiency and power,” said GM Spring Hill Complex Manager Ken Knight. “These engines represent the best of the best available in today’s market, and we’re proud to produce them in Tennessee.”
