Inverse scale chart: L/100km

[sugarsmax]

I'd like to recommend that Liters per 100 km also be shown. This rating is gaining traction in Europe, and provides a more "accurate" comparative scale of economy (the inverse of fuel/distance).

I recognize mpg should perhaps be g/100 miles, but it we are going to use a new scale, we might as well stick with an international unit and use L/100km. The difference in the scales winds up about 2:1 regardless, so it is fairly easy to convert.
