Actually it has less energy, but it's higher octane rating and cooling and detonation properties permit a higher state of tune.
Gentlemen,
E-85 has only about 70% as much energy as gasoline and will deliver about 30% fewer mpg as a result. It is 120 octane however (very detonation resistant) so lots more boost/advance/compression can be used to make more power. It is highly corrosive so cars that use it need stainless steel lines, fuel pump components, etc, or it will rust non stainless steel quickly.

E85 has 73% - 83% of the energy of gasoline. E85 contains 51% - 83% ethanol, depending on geography and season (less ethanol in winter in cold climates, or your car won't start). Given that variability, I wonder how your tune for it. E85 octane rating is about 110 depending on blend.
E10 (what most of us are forced to use) has 96.7% of the energy of gasoline, which is why fuel economy is worse.
Diesel has 113% of the energy of gasoline.

Most import for us is that it supports boost better then gasoline.
Doubt anybody who lives here is concerned about MPG.
Obviously, comments on the fuel delivery system construction are well founded.

You and Chip nailed it. I drive an E-85 hybrid 2010 Toyota Sequoia 4 wheel drive that runs on 87 octane up to the E-85 if necessary. I venture into the woods a lot. I'm assuming that I can use most anything other than diesel, within reason. Just getting broken in with 45K miles.
