FUEL CONSUMPTION AND CO2 EMISSIONS.

BMW Z4 Roadster M40i:
Fuel consumption in l/100 km (combined): x.x–x.x
CO2 emissions in g/km (combined): xxx–xxx

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

Fuel consumption and CO2 emissions.

 

BMW Z4 Roadster sDrive20i:
Fuel consumption in l/100 km (combined): 6.9–5.8
CO2 emissions in g/km (combined): 158–133
 

BMW Z4 Roadster sDrive30i:
Fuel consumption in l/100 km (combined): 7.3–6.9
CO2 emissions in g/km (combined): 166–157
 

BMW Z4 Roadster M40i:
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. For vehicles newly type-approved since 01.01.2021, the official specifications exist only according to WLTP. Further information on the NEDC and WLTP measurement methods can be found at www.bmw.de/wltp
