Starting from 2007 season, all IndyCar Series entrants (outside the Indy 500) utilized the IR-05 chassis version after Panoz defected to Champ Car World Series to replace Lola as the spec chassis supplier for that series in the same season. In 2009 one year after IndyCar unified with Champ Car all entrants (including entrants for the Indy 500) used the IR-05 making it the only chassis used in IndyCar from 2009 to 2011.
