VW Squeezes More Efficiency out of Polo BlueMotion: 3.8 L/100KM
20 July 2007
Volkswagen has squeezed an extra one tenth of a liter per 100km of fuel economy out of its Polo BlueMotion diesel (earlier post), lowering the vehicle’s fuel consumption to 3.8 l/100km (62 mpg US). With the decrease in fuel consumption, the Polo BlueMotion’s CO2 emissions hit a low 99 g/km.
BlueMotion is VW’s label for the most economic models in a class. The Polo BlueMotion, which uses a modified version of the 3-cylinder 1.4-liter TDI diesel engine in the conventional Polo, was the first of the series. A Passat BlueMotion followed, and a Golf BlueMotion will be available in the autumn.
These models are also constantly being further developed as standing still would, of course, represent a step backwards.—VW
VW focused on optimizing the engine configuration to achieve the extra efficiency. The three-cylinder 1.4 TDI with its comparatively high torque of 195 Nm also allows a high gear ratio.
A good aerodynamic drag coefficient (Cd) of 0.30 as well as minimum rolling resistance tires also contribute to the savings. The BlueMotion comes with a diesel particulate filter (DPF) as standard.
