The driving cycle of the WLTP is called WLTC – Worldwide Harmonized Light Vehicle Test Cycle. For different vehicle models, the WLTP has three different driving cycles, which take account of the respective power-to-weight ratio. Most cars registered in the EU, which have a power-to-weight ratio of more than 34 kW/t (46 PS/t), are assigned to WLTC Class 3. The test cycle for Class 3 vehicles is made up of four parts – low, medium, high, extra-high. These simulate urban, extra-urban and motorway driving.
