Fun info from stock Ioniq testing over at clean mpg. My numbers aren’t that high, but I do have over 100k miles and that’s on a new car testing

Still, over 80mpg at 50mph is pretty good stock with no mods!

A third party test by Emission Analytics over an entire tank of fuel, under the same conditions would be interesting.
The shorter the test, the lower the resolution.
