Fuel consumption and CO₂ emissions. The CO₂ emissions, fuel/electricity consumption and all electrical performance were determined using the WLTP (Worldwide harmonised Light Vehicle Test Procedure) test method. These figures may differ from those obtained under real working conditions, as such results are influenced by many factors such as accessories fitted, tyres, load carried, driving habits, weather conditions, ambient temperature, road surface and infrastructure, terrain effects, battery charge level, etc. To compare CO₂ emissions, fuel/electricity consumption and all electrical performance of other vehicles, use data obtained using the same test method.
