In real driving conditions, deviations from the certified standard values may occur. The actual values depend on a variety of individual factors, including driving style, environmental influences and route conditions. The fuel/electricity standard consumption is determined in accordance with measurement method 715/2007/EEC in the currently valid version. The stated values for energy consumption and CO₂ emissions are Swiss values. These are values that were determined in the WLTP measurement cycle. Depending on driving style, road and traffic conditions, environmental influences and vehicle condition, consumption values may deviate from the stated values in practice. The figures do not relate to an individual vehicle and do not form part of the offer, but are provided solely for the purpose of comparison between different vehicle types. To ensure that the energy consumption of different drive systems (petrol, diesel, gas, electricity, etc.) can be compared, they are also shown as petrol equivalents (unit of measurement for energy). CO₂ is the main greenhouse gas responsible for global warming; the average CO₂ emission of all (cross-brand) vehicle types offered is 113 g/km for the year 2025; the target value is 93.6 g/km.
