Another reason why I am beginning to suspect variatons between cars -- my friend also recently purchased a IV with solar. She was a complete newbie but on her recent long drive was able to achieve 59mpg (trip display) overall. She lives about 30 miles from me so the general topography and weather is going to be similar, but she is routinely getting better mileage results.

43 is my best tank. 50-mile commute (round trip) daily, mostly interstate, mountainous, at 70-75, but it's waaaaaay, better than the 19-20 I was getting in my ghetto sled.

I too may concur... The one variable seems to be the battery pack.......

Given as complicated a piece of machinery as the Prius is I would be astonished if there were not variations between cars.

I have a V and get 44 - 47 city really working at it. Coasting down hill and to a stop. I have never matched city numbers put out by Toyota. Highway is a lot easier on cruze and the numbers are closer to projected.

I bought my car because of gas millage. Getting 50+ miles per gallon is incredible; however, getting low to high 40 miles per gallon is also super fuel economy. If you make a small comparison between Toyota Matrix and Toyota Prius, you will see that Matrix's gas millage is around 32 MPG during summer and 28-30 MPG during winter WITH THE SAME 1.8L ENGINE.
It is incredible that we can get 44+ MPG with our cars, even though, our cars weight is 3000 lb.
I calculate my gas millage everytime I am at the pump, and my millage varies between 45-50 MPG, and I can say that this is super good news.
I hope to stay in this range during winter.
All I can say is ENJOY YOUR CARS and try to improve your driving habits. We are owners of one of most advanced cars on the planet and help more or less to save it.

Hi All,

I doubt the differences are due to variations in vehicles. The first thing to learn about driving a Prius is the accelerator dead zone, which is really not dead. When cruising along the pedal has a range or positions where no speed up or slow down will occur. When at the most lifted portion of this range the car will get better gas mileage, but it will take long to get into an effective gear ratio for quick accelleration. Alternatively, at the most depressed portion of the constant speed accellerator pedal position the car gets the worse mileage, but it will respond to accelleration requests very quickly.

People tend to learn this subconciously over time. But know about it up front one can work towards the desired results conciously.

Hills and windys ( driver is probably the largest fact LOL) have alot to do with it
Drive into a 20mphr head wind and see what happens
By the way why do I always drive into a headwind going to work, and drive into a head wind driving home. No matter is the job site is east , north or west of the house mmmmmm
