2013 Indianapolis 500

Event background

• For the first time since 1989, the Indy 500 was part of an Indy car "triple crown" along with Pocono and Fontana. A $1 million bonus prize was offered for any driver to win all three races in the same season.{{cite news
• Lotus, who fielded underpowered and uncompetitive engines in 2012, was released from its contract, and did not participate from 2013 onwards.
• On December 21, 2012, Firestone signed a five-year contract extension to be the exclusive official tire supplier through 2018.
• Following its popular success during the festivities surrounding Super Bowl XLVI, a zip-line was installed in the infield.
• After missing the 2012 race due to an illness, Jim Nabors returned to perform "Back Home Again in Indiana" during the pre-race ceremonies. It was his 33rd year performing the song in-person, and 35th overall.

Selected rules and rule changes

• Cars will be allowed 130 kPa of turbocharger "boost" during practice (Saturday through Thursday), Carb Day, and race day. Cars will be allowed 140 kPa of boost for "Fast Friday" practice, and during time trials.
• All entries will be allowed a total of 33 sets of tires for practice, time trials and race day. Rookie orientation participants receive four additional sets for exclusive use during that session, and likewise refresher test participants receive two additional sets for use during that session. Entries that qualify for the Fast Nine "Shootout" on Pole Day will receive an additional new set of tires for use during each shootout qualifying attempt, but they must be returned and can not be used during the race.
• Full-time IndyCar entries must adhere to the required 2,000-mile engine mileage limits. Unapproved engine changes will see a 10-position grid penalty at the next race of the season (Detroit). Most full-time teams will enter the month with the same engine they used earlier in the season (Brazil, Long Beach, etc.). The 2,000 miles on the engine must be exhausted during practice before installing a fresh engine for "Fast Friday" and qualifying. At the close of time trials, an additional fresh engine may be installed for Carb Day and race day, without penalty. However, the time trials engine (and the race day engine) must be re-installed and utilized for later events if it still has miles remaining on it.
• Part-time teams utilizing the "Short" engine program will be provided with one engine for use during practice, time trials, and race day.

Schedule

• Includes days where track activity was significantly limited due to rain

:As the segment came to a close, the attention focused on Graham Rahal, Josef Newgarden and Simona de Silvestro. All three were among the drivers attempting to make the top 24 for the day. Rahal was too slow to make the field, while de Silvestro managed to bump her way in. In the last 30 minutes, Townsend Bell made two attempts, the second of which bumped his way in. With time running out, Newgarden was bumped out by James Jakes. Newgarden ran out of time to get back in line to make an attempt, and would have to wait until Sunday to qualify.

Pole Day time trials: Fast Nine Shootout – Saturday, May 18

• Weather: 80 °F, mostly cloudy
• Summary: The top nine drivers from segment 1 returned to the track for the Fast Nine Shootout to determine the pole position. Due to the rain delay earlier in the afternoon, the Shootout segment was rescheduled for 6:30 p.m. Each of the nine cars would be allowed one qualifying attempt.

:Marco Andretti was the first driver to make a significant improvement on his starting position, putting himself tentatively on the pole. The next car out, Ed Carpenter, raised eyebrows with a first lap of 229.347 mph, and a four-lap average of 228.762 mph. Carpenter bumped Andretti off the top spot, but still had four drivers waiting to make attempts. Rookie Carlos Muñoz squeezed himself on to the front row, landing in second starting position. The final driver with a shot for the pole was Will Power, who was fastest in segment 1. Power's first lap was in the 229 mph range, but his third and fourth laps dropped off significantly. Power ended up 6th, and Ed Carpenter secured his first Indy 500 pole position. It was the first pole for an American-born driver since Sam Hornish Jr. in 2006, and the first by an owner/driver since A. J. Foyt in 1975.

Bump Day time trials – Sunday, May 19

• Weather: Partly Cloudy 82 °F

Race summary

Start

For the first time since 1987, multiple three-time winners of the race were in contention (Franchitti and Castroneves); however, neither driver ended up being a serious threat to win the race. The race started at 12:15 p.m. EDT (4:15 p.m. UTC). Ed Carpenter started in pole position, but Marco Andretti, who started in third position, soon took the lead. The initial start and first laps commenced without any crashes or yellow flags.

First half

The first caution flag flew when J. R. Hildebrand hit the wall in Turn 2 on the fourth lap of the race, just after posting the fastest time for a lap in the race. Hildebrand had almost won the 2011 Indianapolis 500 but lost due to a crash during the final lap, and then in the 2013 was out of contention after the early crash. On lap 36, driver Sebastián Saavedra was bumped between turns three and four and subsequently crashed into the wall outside of turn four. Driver Pippa Mann later apologized for the accident on her website. The first half of the race featured many lead changes, with Tony Kanaan, Carpenter, and Andretti exchanging the leading spot; however, just before the halfway point in the race, A. J. Allmendinger passed Kanaan to take the lead, with Ryan Hunter-Reay and Andretti following behind in third and fourth, respectively.

Second half

Allmendinger, leading with under 90 laps to go, had a clasp from his seatbelt come loose and was forced to make a pitstop so his pit crew could refasten it, losing the lead. Driver Graham Rahal then crashed with 7 laps left to go, bringing the race under a yellow caution flag. Ryan Hunter-Reay had been in the lead during this caution flag, but when the caution ended, Kanaan, who ran in the top ten most of the race, slipped by Hunter-Reay to take the lead. Just when Kanaan led in the first turn, Dario Franchitti crashed with three laps left, causing another yellow caution flag that would last for the remainder of the race. Under the yellow flag, Kanaan finished the final 2.5 laps to win his first Indy 500, with Carlos Muñoz in second place and Hunter-Reay in third. The race featured more lead changes than any previous Indianapolis 500 with 68, twice the number of the previous record (34), set in 2012. Kanaan said after the race, "I was looking at the stands, and it was unbelievable ... This is it, man. I made it. Finally they're going to put my ugly face on this trophy".

Race statistics

• Lead changes: 68 among 14 drivers

Record and milestones

Numerous race records and statistical milestones were set during the race:

• The race was completed in 2 hours, 40 minutes, 3.4181 second at an average speed of 187.433 mph. It was the fastest Indy 500 in history to-date, breaking the record set by Arie Luyendyk in 1990 (185.981 mph). The speed record stood until 2021.
• There were 68 official lead changes, breaking the record of 34 set in 2012. This record still stands as of 2021.
• There were 14 different leaders, breaking the record of 12 set in 1993 (this record was later broken in 2017 and 2018 with 15).
  • Unofficially, there were 84 lead changes between 15 drivers. Lead changes and leaders are only scored at the start/finish line. However, there were 16 additional interim lead changes during the course of the race, and one additional driver, Dario Franchitti, briefly led the field exiting the pit area on lap 189.
• A total of 26 cars were running at the finish, tying the record set in 1911 (40 cars started that year). This record was broken in 2021 (30).
• A total of 19 cars finished on the lead lap, tying the record set in 2009. This record was broken in 2021 (22).
• The 33-car field completed a record total of 5,863 laps out of a possible 6,600 (88.8%). This record was broken in 2021 (6,308).
• There was a green flag stint from lap 61 through 193 (a total of 133 consecutive laps without a caution). That breaks the record in the modern era for most consecutive laps completed without a caution. Since the "pack-up" rule was adopted in 1979, the previous longest stretch of green flags laps occurred in 2002 (74 consecutive laps). Note that this record was later broken in 2014 (149 consecutive laps).
• There were only 21 laps run under caution, breaking the modern era record of 26 set in 1990 for a full 500-mile race. This record was broken in 2021 (18 laps).
• Winner Tony Kanaan won the race in his 12th attempt, matching the mark set by Sam Hanks (1957). Hanks qualified 13 times, but started only 12 due to an injury in 1941.
• Car #11 won for the first time.
• Hélio Castroneves completed the full 500 miles without relief for a record 9th time in his career. Ted Horn and A. J. Foyt had done so eight times.
• Scott Dixon completed the full 500 miles for a record-tying 6th consecutive year.
• Scott Dixon has completed a record 1,566 consecutive laps dating back to the start of the 2006 race.
• Ed Carpenter led the most laps during the race with 37. That is the lowest total by the driver leading the most laps during a single race. In 1996, Roberto Guerrero had previously set that low mark when he led the most laps in 1996, his total was 47.
• There were seven different leaders in a seven-lap stretch during laps 120–126. This betters a mark set in 1981 when there were five different leaders over a five-lap stretch from lap 56–60.
• For the third year in a row, the lead changed hands with less than three laps to go.
• Unknown to all at the time, this would be Dario Franchitti's final Indy 500. On October 6, 2013, Franchitti was involved in a serious crash in the Grand Prix of Houston, when his car flew into catch-fencing after contact with the cars of Takuma Sato and E. J. Viso. Franchitti suffered 2 fractured vertebrae, a broken ankle, and a concussion in the crash. A month later, on 14 November, Franchitti announced his immediate retirement from motor racing on medical advice; he retired with 31 victories from 265 starts in his American open-wheel racing career, a tally which put him in a tie for ninth on the all-time wins list with former teammate Paul Tracy.
