Information about the data.

  • The fuel consumptions and CO2 emissions figures 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 consider the different size of the selected wheels and tires.

    The values for the BMW i8 Roadster xDrive20i and the BMW i8 Roadster xDrive30i are already based on the new WLTP regulation and are translated back into NEDC-equivalent values in order to ensure the comparison between the vehicles. With respect to these vehicles, for vehicle related taxes or other duties based (at least inter alia) on CO2 emissions the CO2 values may differ to the values stated here depending on national legislation. Please find more information about the WLTP-Procedure here

    The values for the BMW i8 Roadster xDrive20i and the BMW i8 Roadster xDrive30i are provisional figures.

    Unladen weight (EU) in kg: the figure quoted includes a 90 % tank filling, 75 kg for the. Unladen weight applies to vehicles with standard equipment. Optional equipment may increase this figure.

    The CO2 efficiency specifications are determined according to Directive 1999/94/EC and the Pkw-EnVKV and based on the fuel consumption and CO2 values according to the NEDC cylce 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
