The Golf BlueMotion: Another car to sneak under 120g/km CO2

Volkswagen Golf BlueMotion

Following on from the Polo BlueMotion , Volkswagen is set to launch a Golf version of their super-efficient model.

At just 4.5 litres of diesel per 100 km (62.8 mpg), the fuel consumption of the new Golf BlueMotion has been reduced by a full 0.6 litres compared to the original model. Similarly, CO2 emissions have been reduced from 135 g/km to 119 g/km. Actions taken on the BlueMotion mean that distances of more than 1,200 km (745 miles) are possible on just one tank of fuel (55 litres).

After the Polo, Passat and Passat Estate, the Golf is the fourth Volkswagen to wear the new BlueMotion environmental badge on its radiator grille and rear hatch, identifying it as the most economical model in the range. The Golf BlueMotion, with its 77 kW / 105 PS TDI engine, has new engine management software that reduces the idling speed, and it has that all-important particulate filter. With longer ratios in third, fourth and fifth gears, engine speed levels are also lower while driving. These actions alone reduce consumption by about 0.2 litre.

The underbody has been trimmed and thereby flow-optimized, and the radiator grille has been partially enclosed. To ensure that the TDI engine still gets enough cooling air, the Golf BlueMotion has a dual fan. Due to aerodynamic design measures, including lowering of the chassis, the Golf’s cW value of 0.32, which in itself is a good value, has been further improved to 0.30.

The Golf BlueMotion also has light-running tyres, size 195/65 R15, optimized for rolling resistance; they are at higher air pressure, elevated by 0.3 bar. All these modifications mean that the top speed of the Golf rises from 187 km/h to an electronically limited 190 km/h (118 mph).

Market introduction of the Golf BlueMotion is scheduled for the end of this year in Germany. UK details will be announced closer to launch in early 2008.

In total, six new Volkswagen models with environmentally-friendly technology will debut at the International Motor Show (IAA) in Frankfurt, the world’s largest car show.
