ALL new vehicles sold in Australia are subject to Australian Design Rule (ADR) 81/02. This is a fuelconsumption test based on the Economic Commission for Europe Regulation 101. The test is carried out on a ‘rolling road’ dynamometer in a laboratory, not on actual real-world roads.
The test covers a mere (and theoretical) 11km, and is done in two parts. The first, called the Urban Cycle, is from a cold start and consists of a series of accelerations, steady speeds, decelerations and idling. The maximum speed is 50km/h, the average speed is 19km/h and the distance ‘covered’ is just 4km.
The second test, called the Extra Urban Cycle, is conducted straight after the Urban Cycle (hot start) and consists of approximately half steady-speed driving with the remainder being acceleration, deceleration and some idling. The average speed is 63km/h, with one spike that reaches 120km/h. The total second test ‘distance’ is 7km.
