The Skoda Fabia Greenline estate will emit 89g/km of CO2 when it goes on sale this summer.
Despite having a potential 1460 litres of boot space, the Fabia estate has headline emissions figures of 83.1mpg and 89g/km.
The lower emissions are chiefly down to a new 1.2-litre three-cylinder turbodiesel engine, which replaces the 1.4 unit used in the older model
The engine is linked to a stop-start system, an energy recuperation system and a gearshift indicator. The car is also lower than the standard model and is fitted with low rolling resistance tyres.
The Roomster Greenline fitted with the same engine averages 67.3mpg and 109g/km.
