The energy derived from burning gasoline comes basically from the bonds breaking to form new molecules (like C02).
The bulk of a typical gasoline consists of hydrocarbons with between 5 and 12 carbon atoms per molecule.
Ethanol has 2 carbons.
According to a quick google search, the energy of Diesel, gasoline and ethanol is:
Diesel 147000 BTU/Gal
Gasoline 125000 BTU/Gal
Ethanol 84400 BTU/Gal
So E85 is about 90490 BTU/Gal or 72% the mileage of gasoline.
The figures you state are pretty close to that, although you would expect a little better for the highway then what they achieved.

If a person pays 28% less for a product in most cases they get 28% less product in return. That would explain the price difference between the 2 products. They both still overcharge the consumer. The only choice we have as consumers is who do we want to give our money to Big oil companies or Big ethanol companies.
Ignorance is bliss. You are looking at your pocket and not what is good for the country.
We need to tap nuclear, hydro and wind for power. We have over half the worlds known coal reserves and the technology to liquidfy it. We haven proven oil reserves off the East, West and Fla coast, that are not being drilled because not in my backyard the same with refineries.
All of these alternatives reduce our energy dependance on forgien oil except ethanol which increases it.
