Fuel consumption and CO2 emissions of the BMW 8 Series Convertible.

BMW M850i xDrive Convertible:
Fuel consumption in l/100 km (combined): 10.8–10.7
CO2 emissions in g/km (combined): 246–243

BMW 840i xDrive Convertible:
Fuel consumption in l/100 km (combined): 8.9–8.8
CO2 emissions in g/km (combined): 203-200

BMW 840i Convertible:
Fuel consumption in l/100 km (combined): 8.5–8.4
CO2 emissions in g/km (combined): 195-191

BMW 840d xDrive Convertible:
Fuel consumption in l/100 km (combined): 6.9–6.7
CO2 emissions in g/km (combined): 180-175

Official data on fuel consumption and CO2 emissions were determined in accordance with the mandatory measurement procedure and comply with Regulation (EU) 715/2007 valid at the time of type approval. In case of a range, figures in the WLTP take into account any optional equipment. For newly type-tested vehicles since 01.01.2021, the official data no longer exist according to NEDC, but only according to WLTP. For more information on the WLTP and NEDC measurement procedures, see www.bmw.de/wltp

For more information on the official fuel consumption and official specific CO2 emissions of new passenger cars, see the ‘Guide to Fuel Consumption, CO2 Emissions, and Electricity Consumption of New Passenger Cars’, which is available free of charge at all sales outlets, from Deutsche AutomobilTreuhand GmbH (DAT), Hellmuth-Hirth-Str. 1, 73760 Ostfildern- Scharnhausen, and at https://www.dat.de/co2/

Fuel consumption and CO2 emissions of the BMW 8 Series Convertible.

  • BMW M850i xDrive Convertible:
    Fuel consumption in l/100 km (combined): 10.7 
    CO2 emissions in g/km (combined): 246

    BMW 840i xDrive Convertible:
    Fuel consumption in l/100 km (combined): 8.7
    CO2 emissions in g/km (combined): 199

    BMW 840i Convertible:
    Fuel consumption in l/100 km (combined): 8.2
    CO2 emissions in g/km (combined): 187

    BMW 840d Convertible:
    Fuel consumption in l/100 km (combined): -
    CO2 emissions in g/km (combined): -

    The 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 https://www.dat.de/angebote/verlagsprodukte/leitfaden-kraftstoffverbrauch.html

     

    The figures for performance, consumption and CO2 emissions refer to vehicles with standard transmission.

    [1] Performance data of petrol engines apply to vehicles using RON 98 fuel. Fuel consumption data apply to vehicles using reference fuels in accordance with EU Regulation 715/2007. Unleaded RON 91 and higher with a maximum ethanol content of 10% (E10) may also be used. BMW recommends RON 95 fuel. For high-performance automobiles, BMW recommends RON 98 fuel.

    [2] Official data for fuel consumption, CO2 emissions, power consumption and electric range was determined in accordance with the prescribed measuring procedure and corresponds to European Regulation (EC) 715/2007 in the applicable version. For ranges, data determined as per WLTP takes into account any optional equipment (available on the German market in this case). For vehicles that have been newly type approved since 1 January 2021, only the official data according to WLTP exists. In addition, NEDC values are deleted from the certificates of conformity as of 1 January 2023 by EC regulation 2022/195.

    For more information about NEDC and WLTP measuring procedures visit www.bmw.com/wltp

    Further information about fuel consumption and official model-specific CO2 emissions of new passenger cars can be found in the "Guideline for fuel consumption, CO2 emissions and electric power consumption for new passenger cars", available free of charge at all points of sale, at the Deutsche Automobil Treuhand GmbH (DAT), Hellmuth-Hirth-Str. 1, 73760 Ostfildern-Scharnhausen, Germany, and under https://www.dat.de/co2/.

    [3] The charging performance depends on the state of charge, ambient temperature, individual driving profile and use of auxiliary consumers. The ranges shown are based on the WLTP best case. The charging times apply to ambient temperatures of 23 degrees Celsius after a preceding drive and may differ depending on the usage behaviour.

    [4] The EC unladen weight refers to a vehicle with standard equipment and does not include any optional extras. The unladen weight includes a 90% full tank and a driver weight of 75 kg. Optional equipment may affect the weight of the vehicle, the payload and the top speed if the selected equipment has an impact on the vehicle's aerodynamics.

    [5] Composed of combustion engine drive (specified nominal value) and electric drive (up to specified nominal value).
