Offering 170PS and 400Nm, it will replace the current 163PS 2.0 CDTI engine at the top of Opel’s diesel range, offering 5% more power and 14% more torque while reducing fuel consumption and CO2 emissions.

The unit, which will debut in the Insignia and Zafira Tourer, has also been designed to be impressively quiet and smooth as part of Opel’s focus on ‘sound engineering’ measures to minimize NVH.

‘This sophisticated engine makes a perfect partner for our top models Insignia and Zafira Tourer,’ says Michael Ableson, vice president vehicle engineering Europe. ‘Its high power density, refinement, frugality and sheer fun-to-drive qualities place it among the very best diesels in its class. With Euro 6 compliance, the new 2.0 CDTI fulfills future requirements today, and it will substantially enhance the appeal of our diesel portfolio.’

To ensure it complies with Euro 6 standards, the new 2.0 CDTI uses Opel’s BlueInjection selective catalytic reduction (SCR) system, with the AdBlue solution available at filling stations and Opel dealerships.

Available next year, the new 2.0 CDTI is the first in a new family of large diesel engines developed in-house by a global team of engineers in Turin and Rüsselsheim supported by engineers in North America. It will be manufactured at Opel’s Kaiserslautern engine plant in Germany.

This 2.0-litre CDTi unit is the latest step in Vauxhall’s powertrain offensive, following the introduction of all-new 1.6-litre petrol and diesel engines and a 1.0-litre three cylinder petrol powertrain.
