All California gas is now 10% Ethanol. It contains less energy, so my Benz uses more of it for equivalent performance. On the plus side, it does a great job of cleaning injectors.
As part of a solar energy project at the U of CO at Boulder in 1980, the senior ME class built a solar-powered distillery that made 95% pure Ethanol from Sugar Beet beer. We called it "Solarhol." I ran some of it in a 1961 Oldmobile F-85 V8 sedan after installing larger jets in the carb. The Olds was sluggish on Ethanol. It is possible to get high performance out of Ethanol fuel, but you'll need to raise the compression ratio to about 17:1, like the indoor dirt track race cars do. They use the stuff so the exhaust is clean enough for indoor venues.
Oh, one more experience with Ethanol, also in 1980. I visited Brazil for a conference and three of us hired a taxi to take us up to the Jesus statue above Rio. It was a VW bug converted to Ethanol. We had to get out and walk a quarter mile when the bug just couldn't make the last grade.
My conclusion is, drink the stuff, don't burn it. Natural gas is a more feasible, cheaper alternative to gasoline.
