Fuel Consumption and Co2 Emissions of the Bmw 4 Series Convertible.

  • The values for fuel consumption, CO2 emissions and energy consumption shown have been determined according to the WLTP test. WLTP has been used as the applicable fuel and energy consumption and CO2 emissions figure from 1 January 2021 for vehicle registration tax (VRT). The figures were previously based on the NEDC equivalent. Figures shown are for comparability purposes. Only compare fuel consumption, CO2 and electric range figures with other cars tested to the same technical procedures. These figures may not reflect real life driving results, which will depend upon a number of factors including the starting charge of the battery, accessories fitted (post-registration), variations in weather, driving styles and vehicle load. For plug-in hybrid vehicles these figures were obtained using a combination of battery power and fuel. Plug-in hybrid and battery electric vehicles require mains electricity for charging. More information on the WLTP test procedure can be found here: https://www.bmw.ie/en/topics/fascination-bmw/efficient-dynamics/consumption-emissions.html

    A guide on fuel economy and CO2 emissions which contains data for all new passenger car models is available at any point of sale free of charge.
