The 2012 IZOD IndyCar Series was the 17th season of the IndyCar Series, and the 101st season of American open wheel racing. Its premier event was the 96th Indianapolis 500, held on Sunday, May 27. The series was sanctioned by IndyCar, and took place in three countries on two continents. Chevrolet returned to the series for the first time since 2005 while Lotus debuted, with the later leaving the IndyCar Series after the 2012 season due to poor performance.

Three-time defending IndyCar champion Dario Franchitti entered the season seeking his fourth consecutive championship and fifth overall. Meanwhile, two-time championship runner up Will Power sought his first title. Heading into the final race of the season, Power led Ryan Hunter-Reay by 17 points in a two driver fight for the championship.  After Power wrecked on lap 55, Hunter-Reay was able to finish 4th, and claimed the championship by 3 points.

Among the numerous stories going into the season was the departure of Danica Patrick, who left IndyCar to compete in the NASCAR Nationwide Series. Joining the series was former Formula One driver Rubens Barrichello. A highlight of the season was the introduction of a new chassis and engine package.

After losing Las Vegas as a venue in the aftermath of the death of Dan Wheldon, the series welcomed the return of such venues as Detroit and Fontana. In addition, midway through the season, the inaugural Indy Qingdao 600 scheduled to take place in China was cancelled by the promoter.

It was a triumphant return for Chevrolet after returning from 6 years absence, and an average year for Honda topped by an unexpectedly good performance at the 500 after poor qualifying and thus Chevrolet ending Japanese engine manufacturer nine-year supremacy.

The 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 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.

New chassis
Under the new ICONIC regulations, all teams will compete with a core rolling chassis, called the "IndyCar Safety Cell", 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. 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.

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

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

On April 30, 2011, IndyCar owners voted 15–0 to reject the introduction of multiple Aero Kits for the 2012 season, citing costs. 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," and furthermore, it was put off for 2013 as well. Chevrolet and Lotus had already announced their intention to build aero kits.

2011 Indianapolis 500 winner Dan Wheldon carried out the first official test of the Dallara chassis at Mid-Ohio in August 2011. 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.

Despite the generational change of chassis and engines, the wheel rim and Firestone Firehawk tire sizes would remain same until at least 2024 season.

Fuel cell capacity
The fuel cell capacity of the new Dallara DW12 car was reduced from  to  in an effort of fuel efficiency.

Engine formula

Turbochargers returned to the IndyCar Series 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  with a 12,000 RPM limit. The maximum engine displacement was reduced from , the number of cylinders were scaled-down from eight to six and the engine shape will remain V-shaped. All engines will run E85 fuel; from 2007 to 2011, the series utilized 100% fuel grade ethanol.
The turbochargers are provided by BorgWarner. The third generation of IndyCar Series engines will be used until 2023 season.

Suppliers
On November 12, 2010, Chevrolet was confirmed as an engine supplier for 2012 with a twin turbo V6. The initial list of potential suppliers included Ford, Cosworth, and Mazda. Honda announced a 2.2-liter turbo V6 developed fully by Honda Performance Development. On May 27, 2011, Ganassi and Honda announced their partnership renewal for 2012. On August 19, 2010, Cosworth announced their interest in providing an inline-four engine, however, the plan was eventually scrapped. The Chevrolet engine is built in a joint effort with Ilmor who last time partnered Chevrolet in 1997–2002 (1997–2001 as Oldsmobile) and Honda in 2003–2011, and was introduced in full-works partnership with Penske Racing.

The third engine supplier was announced November 18, 2010 at the LA Auto Show, just prior to the league deadline. Lotus announced a twin turbo V6 engine and an Aero Kit. built in a partnership with John Judd and Jack Brabham (Engine Developments Ltd.) Judd engines were used in the CART series and at the Indy 500 from 1987 to 1992, as well as in sports car racing and F1. Lotus has suffered difficulty in both power and delivery of engines and has since pulled out of the sport.

Confirmed engine suppliers
Chevrolet
Honda
Lotus
The arrival of Chevrolet and Lotus as IndyCar Series engine suppliers were marked the return of multiple engine suppliers since 2005 season when Chevrolet and Toyota were Honda engine competitors.

Rule changes
Any engine changes for an engine that has run less than 1,850 miles will result in 10-place grid penalty at the next race. Further, full-time entries are limited to 5 engines per season. There will be two exceptions:
If an engine fails during a race, in which a new engine may be installed for the next event without penalty.
At Indianapolis, all engine penalties will be served at the next race at Detroit. Further, all full-time season entries will receive a new engine penalty-free between Bump Day & Carb Day.
Beginning at Long Beach for all remaining road/street course events, the pits will remain open throughout non-emergency full-course cautions periods. Previously the pits immediately closed upon the display of the caution flag. The series hopes this will shorten caution periods to as few as two laps.
Also beginning at Long Beach for all remaining road/street course events, cars that are not on the lead lap during an upcoming restart in the final 20 laps will peel off and drive through pit lane on the speed limiter and cycle back to the end of the line. The rule was later expanded to oval races as well, where lead-lap cars will simply drive to the front in position order instead. This is similar to NASCAR's restart procedure, where all lapped cars must move to the rear of the field.
For the races at Indianapolis, Texas, and California, restarts will revert to single-file in response to safety concerns.

Schedule
The 2012 schedule included the following 15 races:

 Oval/Speedway
 Road course
 Temporary street circuit
