An electric drive with a fuel-powered companion
Range-extended electric vehicles use an engine-generator to support electric propulsion. Their energy story differs from a battery-only car.
Canvas of Knowledge · 14 November 2026 · Illustrated explainerTwo energy stores
A rechargeable battery stores electricity and a fuel tank stores chemical energy. Electric motors provide propulsion; the range extender generates additional electrical energy.
Chinese example
Li Auto’s L9 is a range-extended SUV. Its powertrain combines battery-electric driving with an onboard engine-generator for journeys beyond the available battery energy.
Read the architecture
A plug-in hybrid is a wider category. Some designs can also connect an engine mechanically to the wheels. Combined driving range must not be confused with electric-only range.
THE IDEA TO KEEPAn extended driving range does not make the fuel-powered portion emissions-free.
