I understand that it does not get as good of gas milage so it comes out as NOT being more economical than regular.

It's about ten cents cheaper here too. As I understand it, the point isn't to increase gas mileage, but to reduce emissions. Then, you get into the whole issue of corn being a very demanding crop. (I'm still waiting for ethanol from kudzu) There is another benefit of ethanol, it has a higher octane rating. I don't know specifics, I've heard it is about 110 octane for pure ethanol, but that isn't from an extremely reliable source. For turbo/supercharged cars that means lots more power, for others, more compression = more power.
