A plug-in hybrid combines a petrol engine with a larger battery that can be charged from a socket, typically giving 50 to 100 km of electric-only range before the engine takes over. PHEVs reached 9.4% of new EU registrations in 2025, overtaking diesel for the first time, and remain popular with company-car drivers who need long-distance flexibility. Our coverage focuses on real-world electric range and combined consumption — figures that often differ sharply from WLTP claims.
