I just completed a trip of nearly 2200 miles in my 03 Prius. The car computer says I got 53.0 mpg while my calculations yield 50.4 mpg - a 5% error.
Is this just my car or is this consistent across the board?
Michael, at least with the 2005's which I have, I believe the +/- is about 3%. 5 is a bit high I would think. My least favorite part of my Prius is the digital gas gauge. It is almost useless and very inaccurate with it's "bars" progression style of display.

My 2-week new Prius trys to make me happy: In the last 3 tanks, it said
51 mpg, but I calculated to be about 46 mpg.MotorsForum website is not affiliated with any of the manufacturers or service providers discussed here. All logos and trade names are the property of their respective owners.
