FUEL CONSUMPTION AND CO2 EMISSIONS OF THE BMW 4 SERIES CONVERTIBLE.

BMW 430i Convertible:
Fuel consumption in l/100 km (combined): 6.4–6.0  
CO2 emissions in g/km (combined): 147–138


The information on fuel consumption, CO2 emissions and energy consumption has been determined in accordance with the prescribed measurement procedure VO (EU) 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.

 

Further information about the official fuel consumption and the official specific CO2 emissions for new passenger automobiles can be found in the 'New Passenger Vehicle Fuel Consumption and CO2 Emission Guidelines', which are available free of charge at all sales outlets and from DAT Deutsche Automobil Treuhand GmbH, Hellmuth-Hirth-Str. 1, 73760 Ostfildern, Germany and on https://www.dat.de/co2

 

The values 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. 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.

Fuel consumption and CO2 emissions of the BMW 4 Series Convertible.

  • Disclaimer reference invalid
​

  • 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).
