The 2012 season saw the implementation of IndyCar's new ICONIC Plan (Innovative, Competitive, Open-wheel, New, Industry-relevant, Cost-effective), the biggest change to the sport in recent history. The car used through 2011, a 2003/2007-model Dallara IR-05, and normally aspirated V8 engines (required since 1997) were permanently retired. The ICONIC committee was composed of experts and executives from racing and technical fields: Randy Bernard, William R. Looney III, Brian Barnhart, Gil de Ferran, Tony Purnell, Eddie Gossage, Neil Ressler, Tony Cotman and Rick Long. IndyCar accepted proposals from BAT Engineering, Dallara, DeltaWing, Lola and Swift for chassis design. On July 14, 2010, the final decision was made public, with organisers accepting the Dallara proposal.
