What Are The Four Parts Of The WLTP?

What are the four parts of the WLTP?

To work out fuel consumption more realistically, the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) driving cycle is based on a global statistical survey of real driving profiles.

 

It includes four parts with different average speeds: low, medium, high and extra-high. Each phase includes different amounts and degrees of acceleration, braking and stopping - all to simulate everyday driving.
