Munchen, 24. September 2010 – The endeavors of ever smaller consumption has sometimes strange consequences: Since VW offers two technically identical polo variants at the same price, which should be slightly more economical than the other. We wanted to find out with one of the most satisfactory cars at all, how effectively the fires are in practice. For this we turned out a Polo BlueMotion 87 g, which will guide 3,3 liters to 100 km.
Two grams difference
The latest version of the Polo BlueMotion has a 1.2-liter diesel with three cylinders and a power of 75 hp. The standard version POLO 1.2 TDI consumes 3,8 liters to 100 kilometers. The Polo BlueMotion naturally requires less, but here it is already complicated: From the BlueMotion model there are two versions, one with the label "87 g" and one with the nickname "89 g". The values refer to CO2 emissions in grams per kilometer. The driven "87 g" consumes 3.3 liters, while the sister version is a tenthiter more. The two variants are merely different from the available equipment. At the "87 g" Only a few options can be ordered.
Various flywheel classes
So comes the "87 g" in a gantity flywheel class than the 89-G colleague. Background: When the fuel consumption is set on the roller support, the driving resistance of the car must be set with a brake. In the driving resistance, the mass of the vehicle is also included in the air resistance, which is divided into flywheel classes. For example, all cars weighing 1080 kg up to 1190 kg fall into the flywheel mass "1130 kg".
Weight of extras
At first glance confusing, because the 87 g and 89 g version have 1150 kilograms exactly the same curb weight. The Ratsel Solution: This flywheel is always determined with all available extras, as an engineer of VW explained us. With this fully equipment, the weight also increases. Since the polo moves with 1150 kg of empty weight only 40 kg below the nearest high flywheel mass class, VW simply roughs the selection of available extras at the 87 g model. Because in the classification, a few kilograms can make more or less a significant difference.
