The 2006 IRL IndyCar Series starts this weekend the Homestead Miami Speedway with tanks ten percent full of ethanol. Here’s a good story from Crash.net about the history making change and Rahal Letterman’s Team Ethanol. Includes this quote: “Team Ethanol and its key sponsors have made a significant impact on the IRL IndyCar Series in the last few years,” said Bobby Rahal, co-owner and founder of Rahal Letterman Racing. “The leaders of Broin, Fagen and ICM have a vision on how they can positively affect the availability of fuel with ethanol that is a renewable resource.”
