BMW X4 M40i:
Fuel consumption in l/100 km (combined): 9.2
CO2 emissions in g/km (combined): 210
The published fuel consumption and CO2 emission figures are established according to legislated technical specifications (UNECE Regulation 101/UN Regulation 83 and SANS 20101 standards), which sets out the procedures that are used to measure the CO2 emissions and fuel consumption. The claimed figures are established using specific tests under standardised, carefully controlled conditions and may differ from consumption achieved under real world conditions with the influences of altitude, road surface, geographic conditions, vehicle options, temperature, humidity, tyres size and driving behaviour amongst others.
The figures for fuel consumption and CO2 emissions depend on the wheel and tyre sizes selected. Consumption data is determined in accordance to the ECE driving cycle.
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 at all sales outlets.
