Skoda has introduced Greenline eco versions of its recently facelifted Fabia and Roomster models. These are the first of its so-called second-generation Greenline models, which incorporate a number of new technical tweaks that allow them to improve on the fuel consumption and CO2 emissions of the first Greenline badged cars

The Fabia Greenline II and Roomster Greenline II have a new three-cylinder 1.2 litre diesel engine that allows the Fabia, in estate form, to achieve fuel consumption of 83.1mpg, and CO2 emissions of 89g/km on official tests. The Roomster returns 67.3mpg and 109g/km. That performance is aided by a stop-start mechanism that closes down and then automatically restarts the engine during short stops, and an energy recuperation system that recharges the battery under braking.

Skoda is not the first manufacturer to implement a second round of eco improvements on its cars; Ford for example, improved its Focus Econetic a few months ago by adding the option of stop-start technology, while Volvo introduced some tweaks to its S80 DRIVe, which improved its already impressive emissions and fuel consumption figures.

Skoda's big Superb hatches and estates seem to be the most likely candidates to receive the Greenline II treatment next; the existing Superb Greenline, while an impressive performer, uses the Volkswagen Group's old 1.9 litre diesel engine, which is generally being phased out in favour of the latest power units using common-rail technology.
