The compression ratio needs to be higher for E85. Otherwise it will not burn properly and the fuel efficiency will be even lower (as said before, E85 has lower energy than pure gasoline). Also, ethanol is more corrosive than gasoline and the proper modifications need to be made in the engine.

Ethanol has different combustion characteristics; it has less BTU content than gasoline. The engine timing (and probably the compression ratio) need(s) to be changed for a conventional gasoline engine to run on E85.

All cars sold in the US can use E10. Cars not configured as a flex fuel car can not burn E85. In order to use E85 you would need to buy a flex fuel car. Ford and GM both sell flex fuel cars. Finding the fuel is tough. It is mostly available in the midwest. Remeber E85 i s 10% less effcient then Gasoline because it does not have the same energey content.

One of the major reasons is that 85% alcohol is very corrosive. Various parts of the engine would be damaged. Alcohol is so corrosive that it cannot be carried by normal petroleum pipelines. It must be carried by special (Stainless Steel?) tank cars, and mixed in at the last moment before the gas is delivered to the gas station. And that is done for 10% alcohol mix!
