Zusammenfassung:	Emission standards in the European Community are based on the ECE city-cycle. In the future legislation will be extended to emissions on country roads and highways. Due to low speeds and accelerations only 13 % of the total engine operating range are used during the ECE driving cycle in a car equipped with an engine of less than 1,4 1 displacement. The future European extra-urban driving cycle covers in combination with the ECE city-cycle the engine operating range up to speeds of n = 3500 rpm. The mean values of engine speed and load agree quite well with real driving conditions on country roads and highways in France and the FRG.
