Ecotec engines aim to produce power with minimal fuel consumption
General Motors has just revealed a new line of small-displacement engines that they plan to install on various vehicle segments for mass production cars in different markets.
Called ‘Ecotec’, these engines were designed to deliver ‘leading-edge efficiency, refinement and durability’ and will be available on compact cars, mid-sized sedans and even compact crossovers.
GM projects that by 2017, more than 2.5 million Ecotec engines will have been built in at least five manufacturing locations globally.
“Transportation solutions vary around the world and GM is committed to developing engines matched to the needs of the regions where they’re sold. The new engine family is designed to achieve segment-leading refinement and efficiency, and will make its way into five GM brands and 27 models by the 2017 model year,” said Steve Kiefer, GM vice president, Global Powertrain Engineering.
There will be 11 engines in the Ecotec lineup including three- and four-cylinder powerplants that range from 1.0L to 1.5L, some of which will sport turbochargers that will have the same power as much bigger engines but will be 20% more efficient.
Ecotec technology is so much more efficient that same displacement engines from GM, Ecotec 1.4L turbo vs. old 1.4L turbo from the same car, is up to five percent more efficient. It is also quieter than same-displacement engine from the competition, boasting of at least 25% less noise intensity.
Power output is between 75HP to 165HP and with torque ranging from 95Nm and 250Nm depending on the variant. It is also ready to accommodate hybrid and alternative fuels in the future.
The initial target model is the Opel ADAM, which will have the 1.0L turbocharged three-cylinder, while the 2015 Chevy Cruze to be launched in China will have the 1.4L turbo and the 1.5L naturally aspirated four-cylinder Ecotec.
“The new Ecotec architecture represents the most advanced and efficient family of small-car gas engines in GM’s history. Along with performance and efficiency targets, we’ve also aimed for segment-leading refinement with low noise and vibration – and we’ve hit the bulls-eye,” said Tom Sutter, global chief engineer.
One great feature Philippine motorist may appreciate if and when Ecotec engines make their way here is that it has been ‘calibrated to run on regular unleaded gas – even the high-output turbo variants.’
