Brief recap.

E85 can and does make more HP and torque in a modern FFV E85 engine, see GM 2014 5.3

E85 doesn't have 2/3 the btu per gallon of E0, 28% is closer which is closer to 1/4 fractionally than 33% often quoted. Compared to E10 it is 26.5% less btu/gall. (link back a few pages)

Ethanol and gasoline blends don't follow a BTU/mile curve. E85 even though only has 28% of the btu content only looses closer to 18% miles per gallon. (link a few pages back plus my personall data that that link supports).

Methanol seems to be illegal to be used to denature ethanol, ethanol is only a poison if taken in excessive ammount, it is safe to drink in reasonable ammount, they poison it with natural gasoline or regular unleaded before it leave the factory so people can't drink it.

I think that busted most of the myths about ethanol.

The myths about fuel vs food is busted everywhere don't care to get into that aspect here. Petrolum has more influence on food than ethanol.

Emission, yep better to see same old link.

$/mile - market dependent, if E85 is 20% cheaper it wins.
