Official figures, checked September 2026. Values marked ≈ are approximate.
Plug-in hybrid economy is the official WLTP weighted figure, which assumes the battery is charged regularly. With a flat battery a plug-in hybrid runs mostly on petrol, so real economy is much lower on long journeys. Electric economy is shown in miles per kWh.
