The 2012 season of the IndyCar Series was remarkable due to implementation of new ICONIC concept (Innovative, Competitive, Open-wheel, New, Industry-relevant, Cost-effective), the biggest change of the technical side in the series history. The Dallara IR-05 car, used in IRL since 2005, and normally aspirated V8 engines (required since 1997) were permanently retired. New chassis was introduced – Dallara technically known as IR12, and renamed as DW12 in the honor of Dan Wheldon, who tested new chassis in 2011 and lost his life in the 15-car crash at Las Vegas Motor Speedway, the final round of the 2011 season. According new ICONIC regulations, all teams will compete with a core rolling chassis, called the “IndyCar Safety Cell” supplemented with aero kit. Under ICONIC plan, the aerokits which consist of front and rear wings, sidepods, and engine cowlings is open to any manufacturer, with all packages to be made available to all teams. New engine formula introduced the return of turbochargers for the first time since the IRL 1996 and Champ Car 2007 seasons respectively. The newly-revolutionary third generation fuel-efficient engines are single and twin-turbocharged engines, tuned to produce a range of 550–700 horsepower (410–520 kW) with a 12,000 RPM limit. The maximum engine displacement was reduced from 3.5 to 2.2 litres (214 to 134 cubic inches), the number of cylinders were scaled-down from eight to six and the engine shape will remain V-shaped.
Dragon Racing team which debuted in IndyCar racing in 2007 with one-off drives and expanded to full-time entrant in 2009, entered two cars in the 2012 IndyCar Series season; one driven by Katherine Legge, and the other driven by four-time Champ Car champion Sébastien Bourdais. Initially Dragon Dallaras were powered by Lotus DC60 V6 turbo engines. However, since the Lotus engines were shown to be uncompetitive, the team made a change to Chevrolet engines before Indy 500. After Indianapolis Dragon reduced operations to just one car with Bourdais driving the street courses and Legge on the ovals. Bourdais finished 25th in points with a best finish of fourth in Mid-Ohio. Legge finished 26th with a best finish of 9th at Fontana. Legge was third in the Atlantic Championship in 2005, and then spent two seasons (2006-2007) in Champ Car ant two seasons (2008-2010) in DTM.
