General Motors' 'EcoTec' engine family details revealed

Snapshot: General Motors recently revealed the details of three new EcoTec engines

General Motors unveiled its new 'EcoTec' series of petrol engines earlier this year and now company has revealed a lot more details about the new engines which are worthy of discussion. The new engines are measured between 1.0-litre and 1.5-litre capacity. While the 1.0-litre and 1.4-litre are turbocharged petrol unit, 1.5-litre is a naturally-aspirated one. The trio will power a range of small and mid-size GM models under 11 different set of tunes. Depending on the engine, power output vary from 75 BHP to 165 BHP while torque figures will be rated between 95 Nm and 250 Nm.

Along with the compatibility of being employed to do duty in hybrid powertrains, the new engines are claimed to offer leading-edge efficiency, refinement and durability. In more complex term, the company claims the new 1.4-litre engine is 40 per cent more quieter than Volkswagen's 1.4-litre 4-cylinder power plant while the 1.0-litre EcoTec is almost 25 per cent quieter to Ford's 1.0-litre EcoBoost unit.
 

The first EcoTec will be introduced on the Opel Adam which has to be powered by 1.0-litre, 3-cylinder, turbocharged engine. Post that, Chinese market will get the next-generation Cruze in late 2014 with 1.4-litre turbo and 1.5-litre naturally aspirated power plant. The 1.4-litre spec model will have 148 BHP and 235 Nm of torque on its tap and will be delivered to its wheels via new dual-clutch transmission. However, the power figures of 1.5-litre engine are 113 BHP and 146Nm which no doubt are disappointing.

There's no word over when other markets should expect the GM models with new engine family, but company officials have announced to plonk the new engines into five brands and 27 models by 2017 and will be assembled in five countries- US, China, Hungary, Mexico and South Korea across the globe.
