Driving around town during Thanksgiving will easily take you beyond the 44 mile range of the Volt's battery pack. When driving an electric car the first thing you will notice is how quiet it is. There is no revving of the engine and the car moves as silent as the wind. So I was curious what it would sound like once the engine kicked in. Let me tell you, it was pretty uneventful going from battery to gas generator. I would not have noticed had it not been for the change in the power flow graphic. As soon as the gas generator engages, the engine appears in the graphic. Up until then it was just the graphic of the battery. In the Volt, the gas generator is not an engine per se. It is not connected to the transmission. Instead the gas generator is used to generate electricity to move the car. It does not fully recharge the battery although I did notice a small charge in the battery when idling. The gas generator works in tandem with the battery and in this mode gas efficiency seems better than a purely gas powered car. Once I pulled into the garage, I did notice the gas generator running. It made me think about the next time I would be able to charge up the battery to save my gas. Day 5 - Overall performance.
