Figures are for comparison purposes and may not reflect real life driving results which depend on a number of factors including the starting charge of the battery, accessories fitted (post registration), variations in weather, driving styles and vehicle load. For plug-in hybrid vehicles they were obtained using a combination of battery power and fuel, for battery electric vehicles after the battery had been fully charged.
Plug-in hybrid and battery electric vehicles require mains electricity for charging. All figures were determined according to a new test (WLTP). The CO2 figure shown here was translated back to the outgoing test (NEDC) and will be used to calculate vehicle tax on first registration.
Only compare fuel consumption and CO2 figures with other cars tested to the same technical procedure.
