There is no difference between EREV and REEV; they are different acronyms for the same type of vehicle.
In more detail:
- EREV stands for Extended Range Electric Vehicle.
- REEV stands for Range-Extended Electric Vehicle.
Both acronyms describe a vehicle that primarily operates on electric power from a battery but also includes a secondary engine (usually gasoline) acting as a generator to extend the vehicle's range when the battery is depleted. This generator does not directly power the wheels; it only recharges the battery.
Essentially, the terms are interchangeable and refer to the same vehicle technology.
