I am a prius driver since 2007 and have drove about 43 K miles. I came to know about this website recently. I was getting 45 to 47 average MPG and was satisfied compared to 25 to 30 on other non-hybrid cars. Here I found out that others are getting MPG upto 55 and 60. I searched some threads and found few simple changes in my driving style and got the FE increased by 10%. Now I look at an average of 51 to 53 MPG. Thanx Oldwolf and mikewithaprius. I used to drive prius like a conventional car. Below are the changes I made 1) Upto 40 MPH, always try to keep instantaneous MPG within 85% of intantaneous MPH. 2) Glide as much as possible 3) Super Highway mode when possible. I am more than satisfied now. But will keep trying to get more and more MPG without sacrificing time. Toyota delears should make Prius Customers aware of this website when they buy. If you sell your prius I recommend letting your buyers know about this website as well. This is superhit. Thank You all.
