As far as new cars, (which are type approved in accordance with the WLTP) are concerned, the NEDC values will therefore be derived from the WLTP values during the transition period. The additional reporting of the WLTP values is voluntary until their obligatory use. You can find more information on the difference between WLTP and NEDC at Currently, we are still obliged to provide the NEDC values, irrespective of the testing method used.

This may lead to corresponding changes in vehicle taxation from 01 September 2018. Due to the more realistic test conditions, the fuel consumption and CO₂ emission values determined in accordance with the WLTP will, in many cases, be higher than those determined in accordance with the NEDC. From 01 September 2018 the WLTP will replace the New European Driving Cycle (NEDC). Since 01 September 2017 certain new cars have been type approved in accordance with the Worldwide Harmonized Light Vehicles Test Procedure (WLTP), a more realistic test procedure to measure fuel consumption and CO₂ emissions. *Data determined in accordance with the measurement method required by law.
