The WLTP enigma

The WLTP enigma

Is there something strange happening with WLTP?

The Worldwide Harmonised Light Vehicle Test Procedure (WLTP) is the new laboratory certification test for light duty vehicles in Europe. In particular, it is used for the fuel economy labelling of vehicles and the carbon dioxide (CO2) results will be used in labelling and manufacturer fleet average CO2 calculations. Missing the fleet average targets could trigger significant fines for manufacturers.
