Test­ing times

4 x 4 Australia - - Tech Torque -

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.
