Why do you say ethanol degrades performance? Ethanol is an anti-knocking agent when added to gasoline, so it actually enables higher performance.

- averros 7y agoIt degrades energy density of the fuel (by volume). In other words, today's gasoline in US takes you 4% less distance than gasoline from 70s. It also creates problems with internal corrosion (which is why it is not used in aircraft fuels), though modern auto engines are designed to deal with that (and are more expensive because of that, too).
- lutorm 7y agoSure, the energy density is a bit lower, but that's not really what people mean when they talk about "performance". "High-performance cars" don't usually refer to cars that can go a long distance on a tank.
- whatshisface 7y agoYour engine has to be designed for it. It's a niche market I know, but some engines aren't. (Not every gasoline engine is in a car after all.)
