Two-time Indy 500 winner and “Dancing with the Stars” champion Helio Castroneves was in Iowa Wednesday to promote the Iowa Corn Indy 250 on June 22. Castroneves drives for Team Penske in the IndyCar Series.

This will be the second year for the ethanol-fueled race at the Iowa Speedway in Newton. The premier Iowa Corn Indy 250 last year was the second-most watched IndyCar Series race after the Indianapolis 500.

This is also the second year that the IndyCar Series will run on 100 percent fuel grade ethanol.
