The Indy Racing League has been promoting ethanol this year in preparation for the big switch to using the biofuel almost exclusively next year (see AutoblogGreen's Indy roundup here) and league officials say the fuel has performed perfectly so far. The league's director of engineering, Jeff Horton, said, "We've had zero problems since our first test at Phoenix." Tests since then have included six IRL races. A typical IRL race uses about 6,000 gallons of fuel and the Indianapolis 500 burned 30,000 gallons, according to the Richmond Times Dispatch. The IRL has been sipping free ethanol from the ethanol industry and a plant in South Bend, Ind.
