Wie verhalten sich die offiziellen Verbrauchsangaben in Bezug zur Realität?
Im Großen und Ganzen kann man auf die Werksverbrauchsangaben inzwischen 40% draufrechnen:
The update shows that in 2017, for the first time in years, the average gap between official fuel consumption figures and actual fuel use for new cars in the EU did not increase, but rather stabilized at 39 percent. Despite the recent slowdown, the discrepancy between official measurements of vehicle efficiency and actual performance of new cars in everyday driving has more than quadrupled since 2001.
Between 2001 and 2017, average official CO2 emission values of new European cars decreased from 170 g/km to 119 g/km over the New European Driving Cycle (NEDC), a 30 per cent decline. But the official CO2 emission values are determined in a controlled laboratory environment. The gap between real-world and official CO2 emission values grew steadily between the early 2000s and 2016, effectively cancelling out two-thirds of the on-paper efficiency improvements since 2001.
Tja, Papier ist geduldig.
