Is the 170bhp Skoda Yeti 4x4 really more efficient than the 110bhp and 140bhp versions?

I am looking at the Skoda Yeti 4x4 diesel engines available and note that the 110bhp version uses more diesel and emits more Co2 than the 140bhp, which itself also uses more diesel and has higher emissions than the 170bhp engine. Please can you explain? Is the 170 bhp engine newer technology ? In day-to-day use would I really get more mpg? My intention is to retire and move near to Fort Augustus, hence looking at 4WD. Would front-wheel-drive plus winter tyres be nearly as good?

Piezo-injected common rail diesel engines are more efficient than Pumpe Duse diesel engines.
