FCn i shall denote the fuel consumption in terms of kg/h (kilograms per hour) when the vehicle is driven with the constant vehicle speed vi = i × 5 km/h – 2,5 km/h (where i is a positive integer number) in the gear n. These data shall be provided by the manufacturer for each gear n (n = 1, 2, ., #g) and vn min ≤ vi ≤ vn max. These fuel consumption values shall be determined under identical ambient conditions corresponding to a realistic driving situation that may be defined by the vehicle manufacturer, either by a physical test or by an appropriate calculation model agreed between the approval authority and the manufacturer.
FCn i bezeichnet den Kraftstoffverbrauch in kg/h (Kilogramm pro Stunde), wenn das Fahrzeug mit der konstanten Geschwindigkeit vi = i × 5 km/h — 2,5 km/h (wobei i eine positive ganze Zahl ist) im Gang n gefahren wird. Diese Daten werden vom Hersteller für jeden Gang n (n = 1, 2, ., #g) und vn min ≤ vi ≤ vn max übermittelt.
