What exactly is a REEV?
A Range-Extended Electric Vehicle (REEV) is a car that drives like a pure electric vehicle in every situation — the wheels are always driven by electric motors only. It feels smooth, quiet, and instant, just like any BEV.
The difference: a REEV carries a small gas generator (called a "range extender") tucked away in the engine bay. This generator never drives the wheels directly — its only job is to generate electricity and charge the battery if it runs low.
Think of it like a ship's generator: it runs in the background keeping the power on, while the actual propulsion stays fully electric.
