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, 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 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.
