add-on parts, different tyre formats, etc.) may change the relevant vehicle parameters, such as weight, rolling resistance and aerodynamics, and, in conjunction with weather and traffic conditions and individual driving style, may affect fuel consumption, electrical power consumption, CO2 emissions and the performance figures for the vehicle. Additional equipment and accessories (e.g. They are intended exclusively as a means of comparison between different vehicle types. In cases where the NEDC figures are specified as value ranges, these do not refer to a particular individual vehicle and do not constitute part of the sales offering.

It is possible to specify the WLTP figures voluntarily in addition until such times as this is required by law.

In the case of new vehicles which have been type-approved according to the WLTP, the NEDC figures are derived from the WLTP data. For further information on the differences between the WLTP and NEDC, please visit We are currently still required by law to state the NEDC figures. Therefore, the usage of CO2 emission values measured according to WLTP for vehicle taxation from 1st September 2018 on can cause changes in this regard as well.

Owing to the more realistic test conditions, the fuel consumption and CO2 emissions measured according to the WLTP will, in many cases, be higher than those measured according to the NEDC. Starting on September 1st 2018, the New European Driving Cycle (NEDC) will be replaced by the WLTP in stages. Since 1st September 2017, certain new vehicles are already being type-approved according to the Worldwide Harmonized Light Vehicles Test Procedure (WLTP), a more realistic test procedure for measuring fuel consumption and CO2 emissions. The specified fuel consumption and emission data have been determind according to the measurement procedures prescribed by law.
