Interesting reading but let me pass on to you that I have a 2000 Buick LeSabre 3800 V6 that gets 30-31 running at the speed limit (not over) and 22mpg in city/rural. Several of my friends also have this car and they say the same thing. So here we have a vehicle that is 1000 pounds or more heavier getting this kind of highway mileage doen't it seem like the Fit should be WAY better?
