New GM Three and Four Cylinder Engines Introduced

New GM Three and Four Cylinder Engines Introduced

With a focus on fuel efficiency and power density, General Motors has introduced a new range of three and four-cylinder engines that will be used in 27 new vehicles by 2017.

These Ecotec engines will range from 1.0-liter to 1.5-liters and use lightweight materials and turbochargers in order to save weight and improve fuel economy.

With direct injection, variable valve timing, variable oil pumps and water-cooled exhaust manifolds, these engines represent the most high-tech and fully featured power-plants in the automakers lineups.

The engines will be made in plants in Flint, Mich., China, Hungary, Mexico and South Korea. There’s a potential annual production capacity of 2.5 million.

The first car to feature the new engine is the European small car, the Opel Adam, which will use a turbocharged 1.0-liter three cylinder. GM says that its small engine will be quieter than the competitions three cylinders found in the Ford Fiesta and other European subcompacts.

GM will also showcase the new engine in a China-only model of the 2015 Chevrolet Cruze. That car will feature a 1.4-liter turbo four-cylinder and a 1.5-liter naturally aspirated model.

    They need something in the Volt that gets better than 35mpg highway!

    Absolutely! Either that, or a 50 mile range so you pretty much NEVER need to use the engine.

    Engine technology is advancing so rapidly I would not be surprised when a 1 liter has 150 ft lbs of torque. Fords 1 liter is close at 130 ft lbs and in a under 3000lb car it should have enough torque to be spunky even with a auto tranny. I agree on the Volt but I do not see the plug in as the future. Eventually it will be spread among pure electrics with ranges exceeding 300 miles on a charge, charging stations in every gas station and toll way. Then comes hydrogen fuel cell vehicles and as they become successful in CA they will eventually hit other states with more refueling stations. If I was in the market for a hybrid the new mid size Accord is Green car of the year with a 46 combined rating. NONE better.
