About these figures: economy and efficiency figures are official WLTP combined-cycle figures for common trims of each model, used as a representative estimate — real-world results typically run 10–20% higher for fuel cars in town driving, and EV efficiency can vary ±15% with weather, speed and load. Petrol converted at 4.546 litres/gallon. This tool gives an informed estimate for comparison, not a guaranteed running cost.
