You're right:
relative to its first value (at 55 mph), the Insight had the steepest change in fuel economy at 75 mph (regardless of whether MPG, L/100 km, or gallons/100 miles is used).
But I still feel that absolute (vs.
relative) fuel economy figures are more meaningful/useful to the average person in a comparison like this. The writer has decided that the slope of the graph is more significant than the actual fuel used in the change from 55 to 75:

...the most significant change in fuel economy comes from the most fuel-efficient vehicles we tested.

Is the slope of a graph more "significant" to the average consumer than the actual change in fuel consumption? Hmm...

someone has brought up the same topic. (Not me!)

This is one place where the difference of the real cost is much better understood in gallons per mile, rather than miles per gallon. The insight's cost for speeding is far less significant than the Mountaineer's loss of "only 6 MPG."
