Fuel consumption and CO2 emissions.
BMW Z4 M40i Roadster:
Fuel consumption in l/100 km (combined): 8.0–7.8
CO2 emissions in g/km (combined): 182–177
Official figures for fuel consumption, CO2 emissions, electricity consumption and electric range were determined in accordance with the prescribed measurement procedure and comply with Regulation (EU) 715/2007 as amended. WLTP figures take into account any optional equipment in the case of ranges. or newly type-tested vehicles since 01.01.2021, the official data no longer exist according to NEDC, but only according to WLTP.

Fuel consumption and CO2 emissions.
BMW Z4 M40i Roadster[1]:
Fuel consumption, combined NEDC in l/100 km (combined): 7.5
CO2 emissions, combined NEDC in g/km (combined): 171
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.
