New Golf BlueMotion: even cleaner After the Polo and Passat, it’s the Golf’s turn to adopt the BlueMotion philosophy, resulting in lower fuel consumption and reduced polluting emissions for this 105 PS TDi engine. There’s nothing revolutionary about the BlueMotion label and the technologies behind it –neither fuel cell nor hydrogen. It is a set of measures and modifications aiming to reduce fuel consumption and polluting emissions. Like the Passat BlueMotion, the Golf of the same name has a 105 PS 1.9-litre TDi engine. Software acting for BlueMotion reduces idling speed which, together with the particulate filter, reduces polluting emissions. Moreover, longer gear ratios (in third, fourth and fifth) make it possible to limit the number of revolutions per minute. So the engine runs in the most efficient output range and for longer lengths of time. This intelligent management reduces fuel consumption by around 0.2 litres per 100 km (62 miles). Smooth, relaxed driving suits the BlueMotion system best. Other modifications have been made compared to a standard Golf. The lowering of the chassis and slight alterations to the silhouette have improved the drag coefficient, which goes from 0.30 to 0.32. It is also fitted with low resistance tyres. What is to be gained by choosing a BlueMotion version over the standard model? A significant reduction in fuel consumption, which goes from 5 to 4.5 l/100 km, and in CO2 emissions (119 g/km instead of 132). |
