2012 Indianapolis 500
For the first time since 1947, the previous year's race winner had been killed in a racing crash in the time between races. Defending race winner Dan Wheldon was killed in a horrific crash during the 2011 season finale, the 2011 IZOD IndyCar World Championship at Las Vegas Motor Speedway. Several winners have missed the following year due to either retirements, injuries, or racing in a different series. The last time the defending champion did not participate in the race due to injury or death was 2004 race winner Buddy Rice, who suffered a concussion during practice, and sat out the 2005 race (also won by Wheldon). The last time a defending Indianapolis 500 champion did not participate in the race under any circumstances was 2007 race winner Dario Franchitti, who was injured in a NASCAR Nationwide Series race at Talladega Superspeedway in April 2008 and had a full-time racing schedule in the NASCAR Sprint Cup Series in 2008. Jim Nabors, who has traditionally sung "Back Home Again in Indiana" during the pre-race ceremonies in most years since 1972, was not able to attend the race due to health reasons. The Speedway sent a film crew to record a video of him performing the song at his home in Hawaii, and aired it on video boards on race morning. Going into the month, there was growing concern about filling the field to the traditional 33 cars. This was due in part to the struggles of Lotus, and lease issues in the first year of the new engine package, namely involving Dragon Racing. However, on Bump Day, the field was filled to exactly 33 cars, with no cars bumped, a similar situation to 2003. Other scheduled events included:


"See Team and driver chart for more information" On April 18, 2012, the official entry list of thirty-four car/driver combinations was released. Former winners entered include Dario Franchitti, Hélio Castroneves and Scott Dixon. In an unusual move, Chip Ganassi Racing sponsor Target changed Franchitti's car number for the month. While Franchitti was legally entitled to using #1, the team decided instead to keep the team's #10 identity for the season, but to celebrate Target's fifty years in business, the car carried #50 for the race. The stylised #50 utilised the Target logo. Former Formula One driver Jean Alesi was listed as an entry for Newman Haas Racing, but the car was later withdrawn. Lotus continued to find a team for Alesi, and struck a deal with Indy Lights team Fan Force United to run a car. Rubens Barrichello, winner of the 2002 U.S. Grand Prix at Indy was the first former winner of that event to attempt to qualify for the Indy 500. Michel Jourdain, Jr., who had last raced at Indy sixteen years earlier in 1996, was named to Rahal Letterman Lanigan Racing. Jourdain would be the only driver in the field from the 1990s. With John Andretti not entered, not a single driver from the 1980s was in the field. With the introduction of the new chassis and engine package, testing was conducted at the Indianapolis Motor Speedway during the offseason. The first phase of testing involved Dan Wheldon, and testing was conducted on the USGP road course at Indianapolis on September 1, and on the oval in late September. Dario Franchitti and Tony Kanaan tested at Indianapolis in early November for Honda and Chevrolet. Test results were mixed at the Speedway, with drivers complaining of weight imbalance issues, and speeds (208–216 mph) were down from what was expected. For the second year in a row, IndyCar held an official pre-Indy oval test. Since the Indy 500 will be the first oval race of the 2012 season, the league hosted a test for rookies to assimilate with ovals, and to test out an updated aero kit package for Texas Motor Speedway, a 1.5-mile 24-degree banked oval which has been a type of circuit that was questionable in light of the Las Vegas tragedy. The aero kit package at Texas was not used for Indianapolis or Fontana. Indianapolis and Fontana, home of the 2012 IZOD IndyCar World Championship, used the same superspeedway aero and rules package. The test also saw Rubens Barrichello take his first competitive laps on an oval on Monday May 7. Q1 The driver waved off and did not make an attempt during Q2. Per INDYCAR rules, Q1 times determine positions after the drivers who completed Q2. The annual Pit Stop Competition featured twelve participants in a single-elimination bracket-style match-up. Four teams received byes, while eight teams competed in the first round. A total purse of $100,000 was at stake, with $50,000 going to the winning team. The format has two cars competing in a layout that resembles a drag race. The cars race from a standing start and drive into the pit box, change four tires, simulate a refueling, and race to a finish line a few hundred feet down the pit lane. Chip Ganassi Racing won the pit stop competition for the first time, with driver Scott Dixon. Ryan Briscoe led from the start, was drafted and overtaken by James Hinchcliffe, who led at the end of the first lap. The pair swapped the lead again by the end of lap two. There were no accidents at the start and the green flag was given at the first attempt to start the race. Ryan Hunter-Reay overtook Marco Andretti before Bryan Clauson spun exiting turn one, akin to Danny Sullivan's spin in 1985, and brought out a caution period. Under caution many drivers chose to enter pit lane. Josef Newgarden stalled in the pits, was restarted and rejoined the race. 2007 and 2010 winner Dario Franchitti spun at his pit box, due to being hit from behind by E.J. Viso, but like Newgarden lost less time as the safety car was deployed. Jean Alesi and Simona de Silvestro were black flagged for failing to run within 105% of the front pace and duly retired. Upon the restart, which was intended to be single file, cars were seen on the pit straight before entering turn one as many as five abreast. At 32 laps Marco Andretti led from James Hinchcliffe and Ryan Briscoe. On lap 33 the stewards declared that Viso would not be penalised for the pit lane incident. No driver was able to pull away a substantial lead over the driver behind and cars behind appeared to face an aerodynamic advantage over those ahead. Takuma Sato then started to set fastest laps by lap 37 and Marco Andretti had led most laps with 15. At the end of lap 46 the pitstops occurred for fuel and tires with Hinchcliffe and Castroneves pitting. Castroneves' pitstop was delayed due to a tire fitting problem. Scott Dixon and Dario Franchitti stopped a lap later. Josef Newgarden stalled again at his second stop, unable to put the car in gear. The Ganassis of Dixon and Franchitti had been setting the fastest pace. By lap 50, one quarter distance, and after the first full pits, Marco Andretti led. There had been six leaders and twelve changes of lead. At the end of lap 75 James Hinchcliffe pitted, then all three Penske cars pitted simultaneously, and Castroneves almost stalled, making it his second flawed pitstop. Pit stops left Dixon leading with Franchitti second some 11 second behind. On lap 79 Mike Conway was given a drive through penalty for hitting a crew member in the pits and breaking his front wing. Conway collided with Will Power and caused a caution, the second of the race, on lap 81. Conway was driving slower than Power, having just left the pits, and slid. The rear of the car lost grip and Conway slid backwards into the wall, and Power hit Conway's spinning car with nowhere left to go as he caught Conway's car on the exit of the turn. The safety car remained out until the end of lap 88. Ana Beatriz spun on the exit of turn one and hit the wall, bringing out another full course caution with her car stopping in the middle of the track. Cars pitted under caution including Hinchcliffe. Dixon and Franchitti led. At the half distance point the leaderboard was
Dixon, Franchitti, Hunter-Reay, Rahal, Wilson, Sato, Kimball, Hildebrand, Bell. On lap 110 Briscoe had a gearbox issue and ran more slowly for a lap and put the car into an emergency gearbox setting whilst running seventeenth. Hunter-Reay stopped for fuel and tires on lap 113. This left all of the top six runners being Honda powered, in contrast to pre-race predictions on relative engine performance and economy. On lap 115 Hildebrand pitted from sixteenth. Rahal pitted afterwards. On lap 119 Franchitti pit stopped from second place with no adjustments made to the car and the following lap Dixon pitted from the lead having led for a total of 37 laps by that stage. This left Sato leading, the eighteenth leader of the day. Andretti ran second. Sato pitted from the lead on lap 124. On lap 125 Hinchcliffe pitted and Barrichello who had led for one lap pitted. On lap 126 Sato lead, with Franchitti behind. On lap 128 Ryan Hunter-Reay retired with a failure of an upright on the car's suspension. On lap 134 the 
leaderboard stood as Sato, Franchitti, Andretti, Dixon, Rahal.
On lap 145 Andretti pitted having complained about a vibration on the car and replaced the tires. Rahal also pitted just before. The caution was issued on lap 146 when Saavedra stopped on the exit of the pitlane. Starting lap 147 under caution the majority of the lead drivers stopped including Sato, Franchitti, Dixon, Rahal, Hinchcliffe and more. Following such pitstops, by lap 150 Sato led followed by Franchitti, Dixon, Hinchcliffe, Wilson, Kimball, Briscoe, Kanaan and Castroneves. On lap 153 the restart occurred and Franchiti passed Sato on the backstraight of the circuit and at the start of lap 154 Dixon passed Sato for second into turn one. On lap 160 Dixon started to pressure Franchitti and had come under pressure from Sato behind. Dixon passed for the lead but starting lap 161 Dario Franchitti retook the lead at turn one. On lap 163 Josef Newgarden stopped due to engine problems, pulling over to the left hand area of grass on the inside of the track on the backstraight between turns two and three, bringing out the safety car and another full course caution. Sato, Franchitti and Dixon pitted under caution, along with Hinchcliffe and others. Hinchcliffe stopped for a longer period than the others and appeared to run over some pit equipment upon exiting. Prior to the restart Dixon led from Franchiti and Sato.
On lap 171 the race restarted. Wilson passed Sato upon the restart. Franchitti repassed Dixon. Starting lap 173 Wilson was repassed by Sato and soon was passed by Carpenter, Kanaan and Kimball having run high on the exit of the turn when passed by Sato and lost speed. By lap 176, 28 lead changes had taken place, one fewer than the 1960 record of 29 changes in one Indianapolis 500 race. Starting lap 178 when Franchitti overtook Dixon this broke the record. The leading Ganassi pair of Franchitti and Dixon appeared to express concern over fuel consumption and speed. On lap 180 Carpenter spun but did not hit the wall, spinning across the track and coming to a halt, then gesticulating at marshals to help turn the car around. This caused a full course caution and seemingly eliminated the need for the leaders to need to refuel. Carpenter then continued. On lap 187 Andretti overcalculated and drove into the wall, sliding across the track and coming to a halt. Tony Kanaan led the race during the caution, but when the green flag waved he soon fell to fourth behind Franchitti, Dixon and Sato. Teammates Franchitti and Dixon traded the lead several times until the start of lap 199, when Franchitti took the lead from Dixon and Sato followed him through into second place. On the final lap, Sato attempted a pass on Franchitti in turn one but spun and hit the turn 1 wall. Franchitti won the race, with Dixon second and Kanaan third. Under the final caution flag of the day, the three friends lined up to cross the finish line side by side. In Victory Lane, Franchitti dedicated his win to the memory of 2005 and 2011 champion Dan Wheldon. When asked about the final-lap incident, he said that he had moved up the track to give Sato room on the inside. Sato had a different view, claiming that Franchitti had forced him nearly into the grass and caused him to lose control. Race officials ruled it a racing incident and confirmed Franchitti as the winner. Owing to the newly-introduced engine formula, Dario Franchitti earned the distinction of the first driver to win in both a normally aspirated and turbocharged engine since Arie Luyendyk (1990 and 1997). Franchitti's victories in 2007 and 2010 came while the series was utilizing normally aspirated engines. Franchitti also became the first driver to win the race with a V-6 engine since George Robson in 1946. Notes: Points include qualification points from Time Trials and 2 points for most laps led. Jean Alesi was penalized 2 laps for ignoring the black flag, which dropped him to last as he had been in front of Simona de Silvestro when they were both black flagged under the 105% rule. Time trials and Carb Day were covered live in the United States on NBC Sports Network. The on-air crew consisted of Bob Jenkins, Jon Beekhuis, and Wally Dallenbach, Jr. Pit reporters included Marty Snider, Kevin Lee, Derek Daly, and Townsend Bell (who also qualified for the race). Robin Miller served as a reporter and "insider." During the Carb Day broadcast Bob Jenkins announced that he would retire from race broadcasting following the season finale in Fontana on September 15th to spend more time with his at the time ailing wife Pam who was diagnosed with brain cancer. Pam would pass away on October 25th. The 2012 Indianapolis 500 (race day) was broadcast live in high definition in the United States on ABC. ESPN3 simulcast the race with an alternate feed of twelve in-car cameras. The overnight television rating for the race was 4.1, and 1.9 for the pre-race. The Fast National rating of 4.34 and 6.9 million viewers marked the highest ratings since 2008. The IMS Radio Network broadcast the race live on approximately 400 affiliates, as well as AFN, the LeSEA broadcasting network, and World Harvest Radio. The broadcast was carried on XM channel 94 and Sirius channel 212. Mike King served as chief announcer for the 14th year (18th year overall with the crew). Davey Hamilton, who did not secure a ride for the race (the first time since 2006), returned to the booth and served as "driver expert."
For 2012, the commercial out-cues used were both renditions by the former "Voices of the 500" and those recited by drivers in the starting field. 1070 The Fan broadcast nightly with "Trackside with Curt Cavin and Kevin Lee", followed by Donald Davidson's "The Talk of Gasoline Alley".
