Since 2007, the Iowa Corn Growers' Association has sponsored the Indy Corn 250, with the goal of demonstrating the fuel performance of higher ethanol blends, such as E100 and E85.

Originally the Indy cars used a 100% blend of ethanol, but in 2012, the fuels changed to 85% ethanol, 15% gasoline to utilize consumer-grade blends.

Iowa Corn Growers Association CEO Craig Floss says the Indy cars started using E100 in 2007, the same year that ICGA began its sponsorship of the race. While he doubts consumers will ever see E100 at the pumps, he does expect a normal grade of fuel in the future to be somewhere between E10 and E85.

The green flag waves at 2 p.m. June 23rd.
