I like the idea of an electric car, but to me, the inconvenience of driving it long distances and looking for charging stations is still a concern. That's why I bought a regular Prius IV. Considering I live at the top of a long hill, I get decent mileage, about 55mpg. A tank of gas (10 gallons) lasts me about 500 miles. I don't have to worry about how far it is to the next charging station. I drive about 10,000 miles/year. That means I use about 180 gallons of gas. In Hawaii, the price of a gallon right now is about $4.40, so I spend about $800/year or about $65/month.
Think about this... If I was to buy a 2014 Toyota Avalon Hybrid, it is rated at 40mpg. At 10,000 miles, I would use about 250 gallons of gas or about $90/month. That does not sound too bad considering the size and class of the car. If I was living in Texas (@$3.40/gallon), I would only spend about $70/month. The car has a 16-gallon tank, so it has a range of about 600 miles.
