As in will it display the mileage that I am getting in my Volt correctly? I don't mean correctly as in figuring in the electricity used, but just being able to display the 4 digits that GM displays on thier site, MyVolt dot com. So far, I have gone over 5100 miles on less than 2 gallons. That works out to over 2360 MPG. Can this be displayed here, or, like most of the surveys I have filled out, is there a limit of 2 or 3 digits?
No, Fuelly isn't going to work correctly for you as the site is now. We don't show values over 100 MPG on cars because 99% of the time the value is due to data entry error. All of the ways we display MPG are based on a standard number of digits as you mention.
If we get enough demand for tracking the gas portion of the Volt we might be able to change things accordingly. But today Fuelly won't work for you. Sorry about that.
Actually, GM tracks the electrical use separately. Or did, the display's been broken for awhile. When it worked It was reporting 30-33 KWh per 100 miles. About what I expected, 300Wh per mile.
VoltStats.net shows more numbers (from the same GM data set), including MPGe and MPGcs, which is the mileage while running the generator. But not Wh per mile. The raw data is collected , but only used to compute MPGe.
VoltStats has over 2 million miles logged from more than 400 cars, so the averages are pretty close to reality for most people.
This site seems to be about beating the average, no?
