The manufacturer expects the new 1.8-litre ECOTEC engine to be the best selling choice in the new Zafira range. Vauxhall said the engine would be integrated into a range of new models in the next few years.
The new 138bhp engine uses valve and cam phasing technology which creates CO2 levels of 187g/km.
The new engine is available in Life, Club, Design, SRi and Special Edition Active versions of the new Zafira now. Prices start at £15,695.
