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 Dallara GP2/11 is a racing car developed and produced by Italian manufacturer Dallara for use in the IndyCar Series. It was developed for use in the 2012 IndyCar Series season, replacing the aging Dallara IR-05 chassis. The DW12 was introduced after 2011 IZOD IndyCar World Championships. The chassis named after Dan Wheldon who killed at Las Vegas Motor Speedway on October 16, 2011.[2]

Starting in 2012 the series moved to using a common chassis supplied by Dallara.[3] Using a single supplier to supply chassis was introduced as a cost control method, and IndyCar has negotiated a fixed cost of $349,000 per chassis.[4] The new specification of chassis also improved safety, the most obvious feature being the partial enclosure around the rear wheels.

This chassis is intended to support multiple aerodynamic kits, but the introduction of these has been delayed until 2014 with teams citing costs.[5]

The ICONIC Project

The IndyCar Car ICONIC Project.

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 naturally 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.[6] IndyCar accepted proposals from BAT Engineering, Dallara, DeltaWing, Lola and Swift for chassis design.[7] On July 14, 2010, the final decision was made public, with organisers accepting the Dallara proposal.[7]

New chassis=

Under the new ICONIC regulations, all teams will compete with a core rolling chassis, called the "IndyCar Safety Cell",[7] developed by Italian designer Dallara. Teams will then outfit the chassis with separate body work, referred to as "Aero Kits", which consist of front and rear wings, sidepods, and engine cowlings.[7] Development of Aero Kits is open to any manufacturer, with all packages to be made available to all teams for a maximum price. ICONIC committee member Tony Purnell gave an open invitation to car manufacturers and companies such as Lockheed Martin and GE to develop kits.[8]

The IndyCar Safety cell will be capped at a price of $349,000[9] and will be assembled at a new Dallara facility in Speedway, Indiana. Aero Kits will be capped at $70,000.[9] Teams have the option of buying a complete Dallara safety cell/aero kit for a discounted price.[9]

On May 12, 2011, Dallara unveiled the first concept cars, one apiece in oval and road course Aero Kit configuration.[10]

On April 30, 2011, IndyCar owners voted 15–0 to reject the introduction of multiple Aero Kits for the 2012 season, citing costs.[11] Owners expressed their desire to introduce the new chassis/engines for 2012, but have all participants use the Dallara aerodynamic package in 2012, and delay the introduction of multiple aero kits until 2013. On August 14, 2011, IndyCar confirmed that the introduction of multiple Aero Kits would be delayed until 2013 for "economic reasons,"[12] and furthermore, it was put off for 2013 as well. Chevrolet and Lotus had already announced their intention to build aero kits.[13][14][15][16]

2011 Indianapolis 500 winner Dan Wheldon carried out the first official test of the Dallara chassis at Mid-Ohio in August 2011.[17] Following Wheldon's death at the season-ending race in Las Vegas, Dallara announced that the 2012 chassis would be named the DW12 in his honor.[18][19]
