Emission Test Cycles

Common Artemis Driving Cycles (CADC)

Time-speed points: Urban | Rural Road | Motorway 150 | Motorway 130

The Common Artemis Driving Cycles (CADC) are chassis dynamometer procedures developed within the European Artemis (Assessment and Reliability of Transport Emission Models and Inventory Systems) project, based on statistical analysis of a large database of European real world driving patterns. The cycles include three driving schedules: (1) Urban, (2) Rural road and (3) Motorway. The Motorway cycle has two variants with maximum speeds of 130 and 150 km/h.

Vehicle speed during the Artemis cycles is shown in the following figures. Artemis cycle definitions also include gear changing strategies.

Selected characteristics of Artemis driving cycles are listed in the following table.
