    The illustrations show optional equipment.

    he values of fuel consumptions, CO2 emissions and energy consumptions shown were determined according to the European Regulation (EC) 715/2007 in the version applicable at the time of type approval. The figures refer to a vehicle with basic configuration in Germany and the range shown considers optional equipment and the different size of wheels and tires available on the selected model.

    The CO2 efficiency specifications are determined according to Directive 1999/94/EC and the European Regulation in its current version applicable. The values shown are based on the fuel consumption, CO2 values and energy consumptions according to the NEDC cycle for the classification.

    For further information about the official fuel consumption and the specific CO2 emission of new passenger cars can be taken out of the „handbook of fuel consumption, the CO2 emission and power consumption of new passenger cars“, which is available at all selling points and at

    All technical data are indicative only and varies as per market and configuration. For more information, please check with your local dealer for all fuel consumption and CO2 emissions.
