The stated fuel consumption and emission data (CO2) of a vehicle have been determined according to the statutory measurement procedures.

From September 1, 2019, all new vehicles are WLTP approved.

Due to the more realistic test procedure, the fuel consumption and CO2 emissions measured according to the WLTP will in many cases be higher than those measured according to the NEDC.

We are currently required to provide the WLTP figures. However, the regulations on car taxation will remain partly based on the NEDC figures until December 31, 2020.

In order to continue to inform our customers clearly, this website, as well as the smartphone apps and derived documents, shows NEDC and WLTP figures (CO2 emissions and fuel consumption) where applicable.

In the case of new vehicles type-approved under WLTP, the NEDC figures are derived from the WLTP data.

In cases where the figures are given as value ranges, they do not refer to a particular individual vehicle and are not part of the sales offer. They are only intended as a means of comparing different vehicle types. Additional equipment and accessories can change the relevant vehicle parameters such as weight, rolling resistance and aerodynamics. And, in combination with weather and traffic conditions and individual driving style, can affect fuel consumption, energy consumption, CO2 emissions and vehicle performance.

The CO2 emissions and consumption values ​​are given for indicative purposes only. It is possible that the values ​​stated for a specific configuration of a vehicle differ from the values ​​shown on the certificate of conformity at the time of delivery of the vehicle. In addition, this difference, if any, may affect the amounts due under applicable law (social, tax, etc.). Contact your dealer for all information about the taxation of your vehicle.
