Another real cool thing is the fact that the car wears a 250 cc 2 stroke petrol engine attached with a generator that supplies power to the batteries. As the battery level reduces, the rear mounted engine/generator starts to automatically top up the battery. So when you arrive at your destination you simply park the vehicle knowing that when you return the battery will be replenished!
