Where values are indicated as ranges, they do not refer to a single, specific vehicle and are not part of the offered product range. They are only for the purposes of comparison between different vehicle types. Additional equipment and accessories (add-on parts, tyre formats etc.) can change relevant vehicle parameters such as weight, rolling resistance and aerodynamics. These factors, in addition to weather, traffic conditions and driving behaviour, can influence the fuel electricity consumption, CO₂ emissions, range and performance values of a vehicle.
