How meticulously did you test that - and does it do lean-burn ?
Even the aerocivic gets better MPG at lower speeds, even though it can remain in lean burn far longer than regular Civics.
Very few Civics will be streamlined as well as that car
Your speed range for the claim seems a bit on the wide end, though I have seen the MPG improve by going a few kph faster (one or 2 clicks on the CC).
Sometimes it just seems to depend on exactly where you are in the engine's fuel mapping, its rpm, and its load - apparently, in some combinations you're better off with a bit more rpm.
