75 mpg Geo Metro

when people claim 75mpg, it means nothing. 75mpg at what speed? 45mph? what temperature? 80 degrees outside versus 40?

Not to mention driving techniques and drafting!

This car was also written about at The Autopian. Ecomodder member MetroMPG was specifically mentioned:

Most people mean it's a one time trip mpg or over a short time

And maybe someone else could achieve more in the same vehicle lol

Yeah in my Ioniq sometime there are trip averages where I can get 78-84 mpg with good weather, moderate speeds, and gentle driving and mild hypermiling techniques but I don’t go around saying my Ioniq gets 80 mpg with no aero mods lol

75 mpg at what speed?

Inquiring minds wanted to know!

I interviewed the builder via email a bunch of years ago. Here's what he said on that subject:

Quote:

2) MetroMPG.com: Regarding the mileage - 75 MPG - is that a combined total of all driving after the conversion, an individual "best" tank, the "highway" figure, or something else? If it's a total figure, did you get any individual tanks that were higher?

Doug Heffron: My 1989 Metro got 75 mpg most of the time, except when there were a lot of hills.

3) MetroMPG.com: Do you use any specific driving techniques to help with your fuel economy?

Doug Heffron: No special driving techniques were used.

4) MetroMPG.com: What kind of driving did you mostly do with the car (e.g. interstate @ 65+ mph, mostly secondary highway use at 55 mph, or mostly "city" driving, etc.)?

Doug Heffron: Most of the driving was on the interstate.
