The new Polo, Golf and Passat BlueMotion models emit just 87 g/km, 99 g/km and 114 g/km of CO2 respectively while every variant is also capable of travelling a minimum of 1350 kilometres on a single tank of fuel.
Each model features aerodynamic changes with a revised front bumper, sill extensions, lower ride height and relocated air ducts behind the grille elements that all contribute to less aerodyanamic drag leading and thusly less loading on the engine and greater economy.
The most efficient model of all, the new Polo BlueMotion, adopts an all-new 1.2-litre three-cylinder common rail diesel engine developing 55kW. The new engine combined with longer gearing through the five-speed gearbox, regenerative braking and Stop-Start systems allows the new Polo BlueMotion to achieve a remarkable 2.74 litres per 100km on the combined cycle.
The new Golf BlueMotion is powered by a 1.6-litre TDI common rail diesel engine developing 77kW. As with the Polo, the Golf features optimised aerodynamics and longer gearing to maximise the efficiency of the engine. Low rolling resistance tyres and automatic Stop-Start also play their part. Golf BlueMotion achieves a combined economy figure of 3.16 litres per 100km.
And finally Passat BlueMotion adopts a 1.6-litre common rail diesel engine developing 77kW for the first time. The new engine, replacing the existing 2.0-litre TDI unit currently fitted to the Passat BlueMotion, allows the new car to return 3.66 litres per 100km on the combined cycle.
All three models are due to go on sale in the UK in early 2010 with prices and specifications due to be announced nearer to the time.
Australian availability of BlueMotion models has not yet been determined.
