This Prius Plugin Hybrid is a very nimble car. You don't need to plug it in at all as it self charges the electric batteries each time you step on the breaks. Just leave it in hybrid mode and you will get 52mpg. If you want to really take advantage of its true potential you can charge it on any normal outlet. Use pure electric mode and once the juice are low it will automatically go into hybrid mode. You can squeeze 95mpge out of this. We usually pump gas once every 2 weeks with this gas saving green car and you can go into the carpool lane with 1 person as this whip is HOV lane approved!
