My spouse and I really enjoy our hybrid Toyota Prius. Have you ever ridden in or drove one?
I have. Does your Prius get good fuel economy?
It gets about 50 miles per gallon which is great and has been rated by the EPA as one of the cleanest cars on the road in terms of emissions.
That is awesome! How are the maintenance expenses compared to a non-hybrid car?
In terms of the short term maintenance rather comparable. It is only later when you have to think about changing out the electric battery that it gets expensive.
I see. Generally how long do Prius batteries last?
In terms of the battery that is charged by the electric generator in these vehicles, the early models only lasted five or so years. The more current ones are projected to last a little over a decade.
That is quite a long time. Many people don't even keep their cars that long. It is amazing how far the hybrid technology has come.
