Het brandstofverbruik, uitgedrukt in liters per 100 km (voor benzine (E5/E10), lpg, ethanol (E85) en diesel (B5/B7)), in m3 per 100 km (voor aardgas/biomethaan en H2NG), of in kg per 100 km (voor waterstof) wordt berekend aan de hand van de volgende formules:
The fuel consumption, expressed in litres per 100 km (in the case of petrol (E5/E10), LPG, ethanol (E85) and diesel (B5/B7)), in m3 per 100 km (in the case of NG/biomethane and H2NG) or in kg per 100 km (in the case of hydrogen) is calculated by means of the following formulae:
