Why is Indycar still using Ethanol

The Clean Fuels Report compared fuel emissions and showed that ethanol exhaust generates 2.14 times as much ozone as does gasoline. The base contribution to smog is 1.7 on a scale where gasoline is 1.0 and higher numbers signify greater pollution. So it is clear that switching to Ethanol will only make pollution worse, not better.

Ethanol is also not a very efficient fuel alterative if you want to save gas. Think about this. In the United States, ethanol is primarily produced from corn. One person could be fed for a whole year on the corn needed to fill a single tank of an ethanol-fueled SUV. Even though ethanol is touted as a clean fuel, it actually increases global warming, destroys forests and inflates food prices.

Many studies have shown that ethanol creates more pollution that typical gas. Using 100 percent ethanol is prohibited in the United States for just this reason.

Is it simply because it is better than methanol?
