2017 Indianapolis 500

A series of procedural rule changes were implemented by the series for the 2017 season, however, none of the rule changes significantly affected the Indianapolis 500.[7] The IndyCar Grand Prix, which opens the on-track activities for the month, a three-day event, had only two days for the Verizon IndyCar Series. That mirrors similar changes made to other races event weekends on the schedule.

• Each entry was allowed 36 sets of tires (Firestone) total, for practice, time trials, and for the race. This remained the same from 2015-2016. The special compound "red" tires are not used for oval events. Entries taking part in the Rookie Orientation Program received an additional three sets for that session, and entries taking part in a refresher test received two additional sets.[8]
• All entries are subject to engine change-out rules. The standard minimum change-out mileage milestone per engine is set at 2,500 miles. Full-time entries are allotted up to two fresh engines for the month of May on-track activities, plus a third engine that is left over from the previous IndyCar Series races. Teams must first mileage-out their engine from the previous races during practice before they can install a fresh engine for Fast Friday practice and/or qualifying. The second fresh engine is intended to be installed for Carb Day and race day, however each team has a certain amount of latitude as to their installation decisions. Both the engine used for Fast Friday/qualifying and the engine used for Carb Day/race day must be re-utilized and properly mileaged out later in the IndyCar season. Unapproved engine changes are subject to penalty.[9] Teams participating in the Pit Stop Challenge are permitted to utilize a back-up car for that event, with one of the older engines installed.
• Engines are permitted 130 kPa of turbocharger "boost" during practice from May 15–18. Cars are allowed 140 kPa of "boost" on Fast Friday practice, and during time trials. The "boost" level reverts to 130 kPa for Carb day and race day.

The 101st Indianapolis 500 was the sixth round of the 2017 Verizon IndyCar Series season, and the 22nd sanctioned as part of the Indy Racing League/IndyCar Series. There were five different winners in the first five races leading up to the Indianapolis 500. The season began March 12 at St. Petersburg, with Sébastien Bourdais a surprise winner. Bourdais won from last place on the starting grid.[10] James Hinchcliffe won at Long Beach,[11] his first victory since suffering a near-fatal accident during practice for 2015 Indianapolis 500. Josef Newgarden won at Barber,[12] and defending series champion Simon Pagenaud won at Phoenix.[13] The IndyCar Grand Prix was won by Will Power, his second victory in the event.

Entering the month of May at Indy, Honda-powered teams were the prohibitive favorites over the Chevys. As the week began, Honda teams were even being accused of "sandbagging."[14] However, each day saw a different driver lead the speed charts, split almost evenly between both manufacturers. Honda began experiencing multiple engine failures,[15] raising significant concerns around the garage area of their reliability.[15]

Graham Rahal, one of the Honda entries, participated in the first private test.

A private manufacturers test for Honda teams was scheduled for Friday March 24. The test was moved up one day due to inclement weather predicted for Saturday.[21] Three Honda teams, Chip Ganassi Racing, Rahal Letterman Lanigan Racing, and Schmidt Peterson Motorsports, tested along with one Chevy team (Team Penske). A total of eleven drivers took to the track on a warm, but windy day. No incidents were reported.[22] Speeds were not reported. Attention during the test focused on Ganassi taking their first laps at the Speedway with Honda power since 2013, after a highly publicized switch from Chevrolet to Honda during the offseason.[23]

A private test was scheduled for May 3 involving Fernando Alonso.[28] Marco Andretti started the day off, shaking the car down shortly after 9:00 a.m. Alonso took to the track and passed all three phases of his rookie test.[29] Alonso completed 110 laps with a best lap of 222.548 mph. Due to rain approaching the area, the test schedule for the day was slightly compressed, in order to complete all three phases before the weather arrived.[30] The test was broadcast as a live stream through IndyCar's social media channels, with combined live viewership of the test was estimated to be in excess of 2 million.[31]

Fernando Alonso completed the three-phase rookie test on May 3 during a private test session.

The Rookie Orientation Program (ROP) was scheduled for Monday from 12:00 p.m. to 2:00 p.m.[32] Four rookies were slated to participate in the session, Fernando Alonso, Jack Harvey, Ed Jones, and Zach Veach. Track time for refresher tests was also available for Jay Howard, Oriol Servià, and Sebastián Saavedra. The three-phase rookie test requirements for 2017 consisted of ten laps at 205-210 mph, fifteen laps at 210-215 mph, and fifteen laps at over 215 mph. The two-phase refresher test consists of ten laps at 210-215 mph and fifteen laps at over 215 mph.[33]

Alonso had passed his rookie test previously on May 3,[33] but was permitted the additional track time during the session. Ed Jones passed his rookie test at 1:08 p.m.,[33] while Jack Harvey experienced gearbox trouble, which delayed him taking to the track for almost one hour. Harvey passed only the first phase of the test after fuel pressure issues sidelined him even further.[34] Veach made no attempt to complete his rookie program, turning in only three laps late in the session. Veterans Howard, Servià, and Saavedra all completed their refresher programs during this time.

Takuma Sato made the Fast Nine Shootout.

• Weather: 81 °F (27 °C), Heavy rain in late morning and early afternoon, partly cloudy later

The first day of time trials locks in the 33 cars that will comprise the starting field, and determines the nine cars eligible to participate in the Fast Nine Shootout for the pole position on Sunday. The start of qualifications was delayed until 4:01 p.m. due to a heavy thunderstorm. As a result of the delays, all drivers were given only one qualifying attempt.[43]

The day was marred by a heavy accident involving Sébastien Bourdais. After completing his first two laps at 231.472 mph and 231.595 mph (the two fastest laps of the day), Bourdais lost control and crashed nearly head-on into the SAFER Barrier in turn two and did a half-flip before coming to rest upright part-way down the backstretch. Bourdais was extracted from his car and immediately sent to Indiana University Health Methodist Hospital where he was diagnosed with multiple pelvic fractures and a hip fracture, rendering him unable to compete in the race.[44]

Despite Honda's dominance in the speed charts during the week, it was Chevrolet driver Ed Carpenter who turned the fastest attempt of the day, with a four lap average of 230.468 mph. Joining him in the Fast Nine were Takuma Sato, Scott Dixon, J. R. Hildebrand, Alexander Rossi, Will Power, Fernando Alonso, Tony Kanaan, and Marco Andretti. Rookie Ed Jones was the first driver outside the Fast Nine. Team Penske was surprisingly lackluster during the session, with four of the team's five drivers failing to make the Fast Nine; Power being the lone exception.[45] Rookie Zach Veach made no attempt to qualify on the day due to damage from a crash in the previous day's practice.[46][47] The only other minor incident of the day involved Pippa Mann, the first car out to qualify on the green track. After a clean first lap, the car stepped out in turn three and nearly tagged the wall in the north short chute. Mann's last three laps dropped off substantially, but she completed the four-lap run 219.282 mph, the slowest car of the day.

Ryan Hunter-Reay led the 10th-33rd group of qualifiers.

• Weather: 74 °F (23 °C), Showers in morning, mostly sunny in afternoon
• Qualifying Summary (Positions 10–33):

Early showers slightly delayed the morning warm-up session, but the skies stayed clear for the rest of the day and qualifying was run as scheduled. Prior to qualifying, Dale Coyne Racing announced that James Davison would fill in for the injured Bourdais in the No. 18 car.[48] As Davison had not driven in a Verizon IndyCar Series race since 2015, he was prohibited from participating in Sunday's qualifying session under Rule 4.3.8.7, an Indianapolis 500-specific rule mandating a driver who had not participated in an oval race prior to the previous year's Indianapolis 500 pass the refresher test (the second and third phases of the rookie test). Furthermore, the backup #18 car needed to be converted from road course to oval trim.

The group from positions 10-33 began qualifying first at 2:45 p.m., running in the reverse order of how drivers qualified in the previous day's session. Zach Veach, having made no attempt on Saturday, was first on course. The day saw, for most drivers, faster speeds thanks to lower temperatures and more rubber on the track than the previous day. Ryan Hunter-Reay was fastest of the session with a four-lap average of 231.442 mph; nearly a full mph faster than anyone else in the first group. Alongside him in the 4th row were Ed Jones and Oriol Servià. Team Penske once again struggled, with Juan Pablo Montoya in 18th being their highest qualifier in the group. No major incidents occurred during the session, though a few drivers, including Jack Harvey and Charlie Kimball, scraped the wall in turn 2 during their runs.

NOTE: Per INDYCAR Rule 8.4.9, Davison, who was ineligible to participate in qualifying, was classified by the Entrant Points of the #18 car during the current season.

Scott Dixon won the pole position, his third career Indy 500 pole.

Fast Nine qualifying began at 5:00 p.m., with each driver given one shot to reach pole position. Scott Dixon took the pole position with a four-lap average of 232.164 mph; the fastest four-lap average since Arie Luyendyk's track record run in 1996. In addition, his first lap of 232.565 mph was the fastest since Luyendyk's track-record 237.498 mph lap, also in 1996. The run was the third fastest pole speed in 500 history, behind only Scott Brayton's 1996 run and Roberto Guerrero's 1992 run. Joining Dixon on the front row were Ed Carpenter, the highest qualified Chevrolet, and defending winner Alexander Rossi. Fernando Alonso stunned during the session, qualifying fifth in his first ever start on an oval circuit.[49]

Alonso's day did not start out entirely smooth, as Honda officials ordered a last-minute engine change in the car. After examining data from the engine, it was decided to install a new engine, with only an hour and a half until the car was due to be in line for technical inspection. The team scrambled to finish the work, and got the car prepared with only minutes to spare. Takuma Sato had a potential front row starting position until his handling went away on his final two laps, and he subsequently brushed the wall in turn two.

Max Chilton went fastest in post-qualifying practice

• Weather: 77 °F (25 °C), Sunny
• Practice summary: During the first of two post-qualifying practices (the other is Friday), cars returned to their race boost levels, bringing speeds back down. The morning practice session was reserved for Indy Lights cars. The first afternoon session started 30 minutes earlier for James Davison to take the refresher test. The practice session ran from 12:30 p.m. to 4:00 p.m., and the second Indy Lights session began at 4:30 p.m. to conclude the day. The day's lone incident came early in the session, when the engine on Oriol Servià's car failed, bringing a short halt to practice. Max Chilton went fastest on the day with a speed of 228.592 mph. Off the track, news focused on pole position winner Scott Dixon. Late Sunday night, after the conclusion of time trials, Dixon accompanied by former driver Dario Franchitti, were robbed at gunpoint at a Taco Bell drive-thru about a mile away from the track. Neither driver was injured in the altercation.[50]

Hélio Castroneves turned the fastest lap during Carb Day practice.

• Weather: 82 °F (28 °C), Mostly cloudy
• Practice summary: The final one-hour practice session was held on Carb Day. Hélio Castroneves led the speed chart, with a total of four Team Penske cars in the top eleven. Polesitter Scott Dixon also ranked in the top five. A total of 960 laps were completed by the field without any wall major contact, however, James Hinchcliffe blew an engine, believed to be Honda's seventh engine failure dating to the IndyCar Grand Prix earlier in the month. Going into the session, Honda teams were limited by the manufacturer to a maximum of 40 laps. Takuma Sato reportedly ran over debris and cut a tire, and later Conor Daly reportedly brushed the wall on the main stretch, which brought two of the several yellow flags during the session.

The Pit Stop Challenge was scheduled for Friday May 26. For the first time in event history, the finals were a best-of-three format.[51] In addition, the set up was revised such that both cars start the race on asphalt pavement. Previously, one lane was asphalt and one was concrete, putting one lane at a grip disadvantage. Due to an earlier engine failure in James Hinchcliffe's #5 car, Hinchcliffe drove Jay Howard's #77 car for the Pit Stop Challenge.

In the second quarterfinals heat, Ed Carpenter was assessed a 5-second penalty due to an unsecured lug nut on the left-front wheel. In the final round, Schmidt Peterson Motorsports (James Hinchcliffe) faced Team Penske (Will Power) in a best two-out-of-three matchup. By virtue of the fastest individual time during the semifinals, Power was awarded lane choice for the first finals heats, and selected the left lane. The teams swapped for the second heat. Power had the best time from the first two finals heats, and was awarded lane choice for the third and final heat. He subsequently selected the left lane again.

• Will Power (Penske) won the first finals heat 11.803 seconds versus 12.843 seconds.
• James Hinchcliffe (Schmidt Peterson) won the second finals heat 12.017 seconds versus 12.300 seconds.
• Will Power (Penske) won the deciding third heat 11.619 versus 13.223 to take the victory. It was Team Penske's record 17th victory in the event.[52]

• Sébastien Bourdais (#18) — injured during a qualifying crash; replaced by James Davison

Race day saw temperatures in the mid 70 °F (21 °C) range with partly cloudy skies. For the first time since 2014, all 33 cars were able to take the green flag to start the race. At the start, Scott Dixon moved into the lead, while Will Power managed to jump up to second from his ninth place start. However, he soon faded and Tony Kanaan moved into second. On lap 6, Kanaan moved past his teammate Dixon for the lead, while Alexander Rossi held third. Rookie Fernando Alonso made a slow start, but quickly began moving his way back up to sixth by lap 19. As pit stops neared, Dixon began to slip down the order, losing second to Rossi and third to Ed Carpenter. The first round of stops came at lap 29, with Kanaan being the first of the leaders to pit. After the sequence, however, Carpenter had moved into the lead, with Rossi second, Alonso third, Kanaan fourth, and Takuma Sato fifth. During the cycle, Jay Howard ran out of fuel, placing him several laps off the pace.

The Andretti Autosport teammates Rossi and Alonso soon dispatched Carpenter, and on lap 37 Alonso moved into the lead. The two dueled for the lead, with Rossi taking back the lead on lap 43, before Alonso returned the favor on lap 48.

On the 53rd lap of the race, Jay Howard drifted wide in turn 2 after being passed by Ryan Hunter-Reay, sending him into the wall.[53] Howard's car drifted across the track after the impact and straight into the path of Scott Dixon.[54] Dixon's car was launched off the back of Howard's, sending Dixon into an airborne flip, before crashing down into the inside wall and piercing a hole in the catch fencing.[55] The force of the crash ripped nearly the entire rear assembly from Dixon's machine. Miraculously, neither Dixon nor Howard were injured in the incident. However, extensive repairs were needed for the catch fencing, forcing the race to be red flagged.[56] After 18 minutes of red flag time for the repairs, cars were fired back up and the race resumed under caution with Fernando Alonso still in the lead after subsequent yellow flag pit stops. During the caution, Hélio Castroneves was forced to make repairs to his car after taking minor damage in his attempt to avoid Dixon's car, forcing him back to 22nd.

When racing finally resumed, Alonso held the lead over his teammates Rossi and Takuma Sato. On lap 61, Rossi returned to the lead, while Sato and Ryan Hunter-Reay both moved past Alonso for position. On lap 65, Sato moved into the lead for the first time of the race. Two laps later came the race's second caution period, as Conor Daly lost control of his car in turn 3 and crashed into the outside wall while trying to make a pass.[57] In the midst of the wreck, Jack Harvey spun attempting to avoid Daly's debris, sending him into the inside wall in the North "short-chute," taking him out of the race as well. During the caution, Castroneves was assessed a drive-through penalty for jumping the previous restart.

The next restart saw Rossi move back around Sato for the lead, while both Hunter-Reay and Tony Kanaan moved around Sato in the following laps to move themselves into second and third respectively. This green flag run was short-lived, though, as caution flew once again on lap 81 as a winglet from Marco Andretti's car broke off and landed on the course on the front straight. The majority of the field elected to pit during the caution, with Hunter-Reay leading Rossi and Alonso out of the pit lane. However, Will Power, Max Chilton, and Hélio Castroneves elected to stay out having made pit stops only six laps earlier during the previous caution, thus placing the trio at the head of the race.

The restart saw Chilton immediately snag the lead away from Power, but by lap 86, those that had pitted during the caution returned to the head of the field. Power began to fall back, while Castroneves and Chilton remained toward the front end of the field. On lap 96, Castroneves moved into the lead of the race after passing Hunter-Reay, while Kanaan moved back into the top five after passing his teammate Chilton.

On lap 104, Castroneves, still off sequence from the previous caution, surrendered the lead to make a pit stop, opening up the cycle of green flag stops while handing the lead back to Hunter-Reay. The majority of the field came in around lap 110, with Hunter-Reay resuming the lead with a margin over three seconds to his teammate Rossi. Alonso, Castroneves, and Power rounded out the top five. The gaps were erased on lap 122, when Buddy Lazier lost control of his car in turn 2 and hit the wall, bringing an end to the former winner's day. During the ensuing caution, Sage Karam's race came to an end when a dead battery caused him to grind to a halt on course.

Racing resumed on lap 129, with Hunter-Reay ahead of Alonso and Rossi. One lap later, though, Alonso moved back into the lead of the race. No sooner was the pass complete when caution waved again, this time for debris on the front straight. The brief caution ended on lap 135, with Alonso and Hunter-Reay switching the lead back and forth before Alonso won out on lap 136. However, pre-race concerns about Honda reliability came to fruition that same lap, as Hunter-Reay's engine suddenly began to smoke on the back straight before slowing and coming to a halt just before the pit entrance.[58] Caution once again waved. Most leaders pitted under this period, Alonso leading the field off pit lane. Rossi, however, suffered major fueling issues, dropping him down outside the top 20. Several drivers elected not to pit during the period, including Max Chilton, Charlie Kimball, J. R. Hildebrand, James Davison, and Ed Jones.

The restart saw Kimball grab the lead from Chilton, but caution waved near immediately, as Ed Carpenter did a half spin and punched a hole in the sidepod of Mikhail Aleshin's car, breaking Carpenter's front wing and sending debris across the track in turn 1. Racing resumed on lap 147, with Chilton quickly moving back around Kimball. On lap 149, Graham Rahal's hope of Indy victory was dashed when a deflating tire forced him to pit under green.

With the race drawing to its closing stages, Hélio Castroneves began moving back up the field, and by lap 151 moved into fourth, while James Davison moved into second ahead of him. Further back, Takuma Sato began moving back toward the front, moving to eighth by the end of lap 163. On lap 166, Chilton made what would be his final pit stop, moving James Davison to the lead. Davison, by leading a lap, became the first driver since Alex Tagliani in the 2016 Indianapolis 500 to lead laps after starting last. Caution flew nearly immediately after this, as Charlie Kimball's engine gave up in similar fashion to Hunter-Reay's.[59] At the same time, rookie Zach Veach rolled to a halt on the back straight, his day done as well. Nearly the entire field pitted during the caution, with Ed Jones and Castroneves leading the charge off pit lane. However, having just made a green flag stop, Chilton resumed the lead of the race. The running order was now Chilton, Jones, Castroneves, Davison, and Sato.

Racing resumed with Chilton in control, but Castroneves began to duel with Jones for second. Behind them, Sato moved to fourth after passing Davison. Eventually, Sato managed to pass both Castroneves and Jones, allowing him to pursue Chilton ahead. Behind them, other Honda cars began attempting to move forward, but on lap 179, Fernando Alonso (then running 7th) fell out of the race as his engine failed coming down the front straight; the third Honda failure of the race.[60] Caution once again bunched up the field.

Racing resumed on lap 184, with Castroneves managing to take third away from Jones. Just behind, chaos erupted in the field when Davison and Oriol Servià made contact in turn 1 triggering a multi-car pile-up that involved Davison, Servia, Will Power, James Hinchcliffe, and Josef Newgarden.[61] Of the five, only Newgarden was able to resume, but only after losing several laps.

Racing resumed with 11 laps to go with Chilton maintaining his lead over Sato. On lap 192, Castroneves was able to make a pass on Sato for second. One lap later, he managed to move around Chilton, placing the Brazilian in the lead of the race. However, Sato passed Chilton shortly thereafter and, one lap later, moved around Castroneves to take the lead. Castroneves made one last attempt to pass Sato with three laps to go, but was ultimately unable to catch back up to Sato. Takuma Sato took victory by just .2011 seconds over Castroneves, while Jones came across the line in third.[62] By taking the win, Sato became both the first driver from Japan and the first driver from Asia to take victory in the 500. Sato also became the first driver to win the Indianapolis 500 and finish on the podium in a United States Grand Prix hosted at Indianapolis, having finished third in 2004. It also marked the first time since 2011 that the winner of the race came from the first three rows. The victory was the third in four years for the Andretti Autosport team.

The race was televised live in the United States on ABC. Allen Bestwick was the lead play-by-play announcer for the race, joined by Scott Goodyear and Eddie Cheever.[64] The race took place just after the highly publicized 2017 ESPN layoffs, of which both Bestwick and Punch were identified as casualties. Both Bestwick and Punch, and presumably the remainder of the contracted on-air crew, was officially terminated a week later after ABC's coverage of the Detroit Grand Prix. However, on February 7, 2018, ESPN communications director Andy Hall announced that the full IndyCar broadcast team, Bestwick and Punch included, would return for the 2018 season.[65]

The broadcast utilized 96 cameras, with 14 cars equipped with three in-car cameras each, and the introduction of Visor Cam, which featured live, first-person camera angles from cameras mounted on the helmets of Graham Rahal and Josef Newgarden. Live in-car camera feeds were available online via WatchESPN. ESPN also introduced a new "Race Strategist" feature, which featured predictive analysis based on various factors that could affect the race. As with all other IndyCar Series events, ESPN International produced a world feed broadcast for international markets.[66]

In the United States, the 2017 Indianapolis 500 was the least-watched edition of the race since the inception of live flag-to-flag coverage, with a 3.6 overnight Nielsen rating (down from 4.1 in 2016). The tape delayed broadcast in Indianapolis (the live broadcast was, as is customary, blacked out by WRTV) saw a 16% increase in viewership over 2015 (the last time the race was blacked out in Indianapolis, since the 2016 edition had its blackout lifted).[67] By contrast, viewership in Spain was significantly high due to Fernando Alonso's debut, with 443,000 viewers and a 3.6% share, higher than the Formula One Monaco Grand Prix that occurred earlier in the day.[68][69][70]

Carb Day, the final practice session, along with the Pit Stop Challenge and Freedom 100, were carried on NBCSN. The booth announcers for NBCSN were Kevin Lee, Townsend Bell and Paul Tracy. The pit reporters were Marty Snider, Jon Beekhuis, Katie Hargitt, and Robin Miller. Lee was joined in the booth by Anders Krohn and Ed Jones the Freedom 100 coverage segment.

The race was carried live by the IMS Radio Network, part of the Advance Auto Parts IndyCar Radio Network. Mark Jaynes served as chief announcer for the second year. The crew for 2017 was largely the same from 2016. Once again, all living former chief announcers took part in the broadcast. Paul Page joined as a guest commentator in the booth, and Bob Jenkins appeared during the pre-race in a pre-recorded segment recapping the 25th anniversary of the 1992 race. Jenkins then served on the Speedway Public Address system team. Mike King also appeared during the pre-race coverage, narrating a pre-recorded segment recapping the IndyCar Grand Prix, and Dave Wilson narrated a tribute to John Andretti (a former IMS Radio Network analyst for the Brickyard 400) who was battling colon concer. During the race, Wilson interviewed vice president Mike Pence, then reported from the track hospital. For the second straight year, Michael Young interviewed the winner in victory lane.

Among the guests in the booth was Governor Eric Holcomb, Mark Reuss (GM), Matt Davis (Advance Auto Parts/Carquest), and James Verrier (BorgWarner). For the first time, the traditional commercial out-cue was recorded by a voice-over announcer instead of the chief announcer or drivers in the field. This was the final 500 in Turn 1 for Jerry Baker as he would depart the crew for and join the public address crew for 2018 when it was decided that Turn 1 would not be used in 2018 but due to a new broadcast booth debuting in 2019 named after Sid Collins, Turn 1's broadcasting location would be reinstated.

According to a study from GfK Custom Research, the broadcast reached 20.5 million listeners, and averaged 8.8 million listeners per quarter hour. It represented a 75% increase in ratings over 2016, and the broadcast was carried on over 350 terrestrial radio affiliates, a 5% increase from 2016.[71]
