[1] In accordance with Directive ECE R85 in its currently valid version.

[2] Figures determined with battery fully charged. This model is a Battery Electric Vehicle (BEV) requiring mains electricityfor charging.

[3] Depending on the local electricity infrastructure and the charging current set on the charging cable.

[4] Wallbox optionally available.

[5] CO2 figures have been converted into NEDC-equivalent values for use with the current VED and BIK tax legislation.

[6] Up to roof in accordance with standard DIN 70020-1.

[7] Figures in accordance with Directive 92/21/EC in the version 95/48/EC (mass in running order, with driver, 68 kg and luggage, 7 kg) for vehicles with standard equipment.

Optional equipment and accessories generally increase this figure, which means that the payload is reduced accordingly.

* The manufacturer’s stated fuel consumption figures are based on the legally prescribed NEDC test cycle, which is performed in a laboratory. These are the only figures we are allowed to publish. It is common that differences occur in real driving conditions compared with these certified laboratory values. They result primarily from conditions different from the legally-prescribed laboratory conditions, for example when ambient temperatures differ (the weather is hot, cold, windy, wet), the vehicle is operated under different loads and many other factors.

For several years, Mercedes-Benz has fully and actively supported the early introduction of the WLTP (Worldwide Harmonised Light Vehicles Test Procedure) and the measuring procedure for Real Driving Emissions (RDE). This procedure is designed to supersede the NEDC, with the goal of bringing standardised and real-world consumption closer together.

Figures shown are for comparability purposes; only compare with other cars tested to the same technical procedures. Figures may not reflect real life driving results, which will depend upon a number of factors including the starting charge of the battery, factory fitted options, accessories fitted (post registration), variations in weather, driving styles and vehicle load.
