Vehicle and engine generator unit for driving vehicle

A vehicle includes a vehicle body, an electromotive driving unit mounted on the vehicle body, an engine operable with a liquid fuel, a generator that generates electric power, and a control device including a power generation control unit and an electric power output unit. The power generation control unit outputs a signal for controlling the engine and the generator, the electric power output unit outputting electric power generated by the generator to the electromotive driving unit. The control device in combination with the engine and the generator constitutes a physically integrated unit that is mountable to and dismountable from the vehicle body. The control device is configured to output a store visit promotion signal to an informing device while the physically integrated unit is mounted on the vehicle body, to prompt a visit to a store where the physically integrated unit is replaceable.
