Quick read from a website:
Straight ethanol has a race-gas-style octane rating of 115. Mixed with 15 percent 87-octane pump gas, E85 lowers this to between 103 and 105 and generally sells for less than 87-octane gasoline. You read that right. We're talking the equivalent of 105-octane race gas for the price of moose-piss pump gas.
While there is a 27 percent reduction in heat, ethanol's strong octane rating allows the use of a higher static compression ratio to take advantage of that resistance to detonation. This means if you were to run E85 in an 11:1 or 12:1 compression engine, E85's higher octane would prevent detonation, which would allow you to run this higher compression ratio and take more advantage of the reduced Btu heat output by squeezing the existing air and fuel a little harder to make more power.
