My Toyota Prius is getting even better gas mileage than it has in the past. This is a bit of a story but I think it is very interesting.
About a month ago I had to have the main battery replaced. This was with about 91,000 miles on my car, which I would think would make it officially beyond the 8 year/80,000 mile hybrid power train warranty. I have had the car for a little over seven years. My dealership, Leith Toyota in Raleigh, North Carolina, replaced the battery under warranty and provided me a rental car at no charge while we waited for the new battery to come in.
I have to say that this is incredible service and far beyond what I would expect. Needless to say I will be going back there for my next Prius or whatever might be even better when the time comes.
However I have noticed that with the new battery I am now getting in the low 50’s for gas mileage instead of the high 40’s. How great is that! I can only surmise that the new battery, while the same basic technology as before, must have been tweaked a bit. I have noticed that my Prius now is more aggressive about turning off the gasoline engine when the vehicle is coasting to a stop or stopped. That will make a great difference right there.
After my last fill-up I actually was getting 55.4 MPG. It is currently at 53.6 MPG. I cannot complain about that a bit. Although I suppose if it ever does drop back down below 50MPG I will be somewhat disappointed.
