Stated fuel consumption and CO2 emissions are measured pursuant to EU Regulation 715/2007 in its applicable version. From 1st of September 2018 the Worldwide Harmonized Light Vehicles Test Procedure (WLTP) has replaced the New European Driving Cycle (NEDC).
From January 2021 onwards, European Union member states are required to ensure that new passenger cars offered for sale, for lease or exhibited in showrooms or similar, are clearly labelled with consumption and emission data according to the new WLTP test cycle. Work is currently underway on the amendment of the German regulatory framework which governs the implementation of this European Union obligation in German law, its final completion however is still outstanding. For a number of new vehicles, NEDC consumption and emission values are no longer available, it is therefore reasonable that the more realistic WLTP consumption and emission values are provided to customers instead.
The official manufacturer consumption and emission values have already been determined on the basis of the new WLTP test cycle and, for some models, calculated back to NEDC test cycle for information purposes. The WLTP values are used for the assessment of taxes.
