BMW WHEELS & TYRES.

We subject the tyres for our vehicles to stringent tests with up to 50 different quality criteria – significantly more than prescribed by the uniform tyre labelling regulation that applies throughout Europe. This is where you will find all the information on the properties of the tyres used at BMW.

FUEL CONSUMPTION AND CO2 EMISSIONS.

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


The illustrations show optional equipment.


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.
