Opel introducing new 1.6L diesel engine family; fuel consumption reduced by up to 10%, Euro 6 compliant

The 1.6-liter CDTI Ecotec diesels will replace existing 1.7-liter engines and certain lower powered versions of the 2.0-liter range. Click to enlarge.

Opel is introducing a new four-cylinder, 1.6-liter turbo-diesel engine as part of the fundamental renewal of its powertrain portfolio. The second family of new downsized power units to be introduced after the gasoline 1.6-liter SIDI Ecotec (earlier post), the 1.6-liter CDTI Ecotec diesels will replace existing 1.7-liter engines and certain lower powered versions of the 2.0-liter range.

Featuring closed-loop combustion control and an aluminum block, the new 1.6 CDTI Ecotec is the first diesel from Opel to comply with future Euro 6 emissions requirements. The engine will be available in a variety of power outputs across several carlines.

Class-leading attenuation of noise, vibration and harshness, high power/torque density and low fuel consumption were the main development objectives.

Initially maximum power and torque have been increased versus the 1.7-liter engine to 136 hp (101 kW) and 320 N·m (236 lb-ft) respectively, while fuel consumption has been reduced by up to 10% compared with similarly powerful 2.0-liter diesels.

The comprehensive renewal of our powertrain portfolio continues at wide-open throttle. Our new 1.6-liter diesel will set benchmarks for refinement, performance and environmental compatibility. By the end of this year we will have launched three all-new generations of gasoline and diesel engines, as part of our roll-out of 23 new models and 13 new powertrains by 2016.

—Dr. Thomas Sedran, Deputy Chairman of the Opel Management Board

The new 1.6-liter diesel and its engine control unit have been entirely developed in-house by a global team of engineers in Turin, Rüsselsheim and the US. This approach has enabled a comprehensive system optimization from the beginning of the design process.

Beginning in spring, the 1.6 CDTI ECOTEC will be manufactured at the same “flex plant” as the new 1.6-liter gasoline engine, in Szentgotthard in Hungary.



Good engine.
I hope it doesn't generate too much soot.
I hope there is anyone left in Europe who might buy one.

In Europe I believe diesel passenger cars have long since been the dominating choice. Over 50% pure diesel, but these run on low sulfer diesel fuel and sound about exactly like gas. Perhaps a slight odor, but to get 20-50% better MPG, that's worth it. Just take a look at a Yaris Gas versus Yaris Diesel. In the U.K. the choice is available, not here in the USA.

The USA/North America seems to bias complex multi-powerplant systems. Those are not cost effective for the people that just need to move at a lower cost and a small budget. Where is the US$20,000 car that gets 55 - 60 mpg? For the student. Why are only the rich people getting the choices here, choices for all please. Part of this is the stigma of diesel in the USA, the manufacturers are shy to bring the models, and of course the government does nothing to help. They have a different agenda.



You should be getting a choice of gas or diesel with the Chevrolet Cruze sometime during the 2nd quarter of this year. I believe that they will offer a 2 liter version of the CDTI ECOTEC but from the above specs, the 1.6 liter would have about the same power as the current 1.4 liter turbo gas or the 1.8 liter NA gas engine.


In the USA there are now lots of small cars being sold that obtain the 55-75 mpg of European wildly optimistic NEDC mileage tests.

Except our tests of these exactly same cars, do not produce 55-65 mpg. They produce a more realistic 40 mpg as do those theoretical mileage Euro cars, using the NEDC inflated tests. Mileage figures that real consumers can duplicate.

The Fiat Cinquecento, 500, and the Chevrolet Spark along with the Ford Fiesta and the Mini, are the same cars as sold in Europe in the A-segment and B segments.

Away with your North American self-loathing. Its obsolete and has been increasingly so since the 1980s.

You can no longer turn your nose up at North Americans and sniff, about the superiority of European car tastes. The cars they can choose are increasingly obsolete, noxious, dirty, pollution emitting vehicles.

It should be embarassing that Europe won't adopt modern pollution controls for several more years, some thirty years after America did. Meanwhile many Third World countries are mandating and driving cleaner cars than Europe forces on its polluted citizens.


I am glad that General Motors is at last attempting to modernize its engine offerings. That real world modernization will save lots of fuel worldwide in the next decade. The Boat-anchor Family II engines are the first to go, as they should have a decade ago.

It appears that a similar program is envisoned to replace the Family 0 engines too. That better, but still obsolete engine family is available and familiar in America as the 1.0 - 1.4 liter powerplant of the Cruze, Sonic, Spark and as the generator for the VOLT.
