A series- or serial-hybrid vehicle is driven by an electric motor, functioning as an electric vehicle while the battery pack energy supply is sufficient, with an engine tuned for running as a generator when the battery pack is insufficient. There is no mechanical connection between the engine and the wheels, and the purpose of the range extender is to charge the battery. Unless there has been a rework of the drivetrain since its first release there is a mechanical linkage in the Chevy Volt.
For some users, this type of vehicle may also be financially attractive so long as the electrical energy being used is cheaper than the petrol/diesel that they would have otherwise used. Current tax systems in many European countries use mineral oil taxation as a major income source.
