Opel is continuing the renewal of its powertrain portfolio, with the introduction of the all-new 1.6-litre four-cylinder, turbo-diesel engine in Ireland later this year.

The Opel Zafira is the first model that will benefit from the major powertrain development programme, which will see 80% of Opel’s engine portfolio renewed by the end of 2016. As part of this powertrain offensive, three entirely new engine families, extending to 13 different engine derivatives with a host of new transmissions, will according to Opel bring cutting-edge technologies and class-leading performance to a wide range of its models.

The programme begins with the arrival of the 1.6-litre CDTi diesel and 1.6 SIDI (Spark Ignition Direct Injection) Turbo petrol engines, the first offspring in a new generation of midsize petrol and diesel engine families.

These engines and transmissions are focused on meeting a growing customer demand for ‘downsized’ powerplants; offering strong power and torque with reduced fuel consumption and CO2emissions. Class-leading NVH (Noise, Vibration and Harshness), high power/torque density and low fuel consumption were the main development targets.
