In an engine, a mixture of gasoline vapor, ethanol and air is hotter than the ideal stoichiometric mixture of gasoline vapor and air. That is what is meant by burning hotter. Ethanol has a lower chemical BTU value than gasoline, so the customer loses mileage. But you are correct that modifications must be done to run it correctly, which is why you cannot put a higher concentration of ethanol in an unmodified engine without problems.

@You're wrong. In a 2 stroke engine, ethanol blended gasoline results in increased heat buildup in the cylinder head and piston. This is deadly on an air cooled engine, especially. Ethanol blended fuel has resulted in many millions of dollars of damages to engines and we're only now finding out that the "gasoline" sold to us at the pump is watered down crap.

incorrect ethanol burns cooler (because of the alcohol) Also ethanol has a much higher potential energy. You can gain a lot of power from ethanol fuel. Of course some modifications must be done to run it correctly. But it does not drop performance.
