1 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

2 EU Unladen mass refers to a vehicle with standard equipment, with 90% fuel tank fill, including a driver (68 kg) and luggage (7 kg). Optional extras and accessories will generally increase this figure.

3 Trailer loads may not exceed the load stated for un-braked or for braked trailer and the max tow bar load may not exceed the value stated.

4 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 1151/2017.Unleaded RON 91 and higher with a maximum ethanol content of 25% (E25) may also be used. BMW recommends RON 95 fuel. For high-performance automobiles, BMW recommends RON 98 fuel.

5 The charging performance depends on the state of charge, ambient temperature, individual driving profile and use of auxiliary consumers. The ranges shown are based on the WLTP best case. The charging times apply to ambient temperatures of 23 degrees Celsius after a preceding drive and may differ depending on the usage behaviour.

BMW 420i Convertible^[8]: Fuel consumption, combined WLTP in l/100 km: 7.4–6.7; CO2 emissions, combined WLTP in g/km: 170–152

^[8]Provisional figures; any missing figures were unavailable at the time of publication.

The stated values are based on the mandatory WLTP measurement procedure. The real life values depend on various factors, e.g. cargo weight, driving style, route, weather conditions, auxiliary electrical consumption (including air conditioning), tires, battery state of health.
