INDIANAPOLIS − Ryan Hunter-Reay has teamed up with two American ethanol companies for this weekend's race at Iowa.

Hunter-Reay is the only American to win a race this season in the IndyCar Series, in Long Beach, Calif. His sponsorship was scheduled to run out following the Texas race. He finished second in the season-opener at Brazil, has three top-five finishes and is sixth in points the best of Michael Andretti's four-car team.

The other drivers are Marco Andretti, Michael's son, former series champ Tony Kanaan and Danica Patrick.

Hunter-Reay had surgery on his left thumb after a pit row accident during the Indianapolis 500 and also was involved in the frightening crash with Mike Conway on lap 199 of the 500.
