2015 ABC Supply 500

Two and a half hours of practice began at 8:30 a.m. on Saturday morning. The first hour was reserved for rookies and part-time drivers only. Beginning at 9:30 a.m., all cars could practice. Charlie Kimball posted the fastest speed at 221.373 mph, the only car to go above 221 mph. Rookie Sage Karam was second fastest at 220.788 mph, followed by Simon Pagenaud at 220.629 mph. Takuma Sato, fifth quickest, was the fastest Honda. At the end of the session, Stefano Coletti brushed the wall in turn three and damaged the steering enough to send him lightly into the pit wall.[2]

Helio Castroneves won the pole with a two-lap average speed of 220.530 mph. Castroneves' Team Penske teammates Simon Pagenaud was second at 220.485 mph and Will Power third at 220.398 mph.[3]

Charlie Kimball crashed in turn three on his first qualifying lap. Kimball lost control at the apex of turn three and impacted the wall with the left side. Similar to the crashes of Josef Newgarden and Ed Carpenter earlier that year at Indianapolis, air got under Kimball's car and lifted it off the ground. The car landed on top of the SAFER barrier, slid along the wall, and impacted a fence pole with the rear wing. Kimball was uninjured and the team switched to a backup car. Qualifying was delayed 48 minutes to repair the catchfence.[4]

A 30-minute final practice session was held at 6:15 p.m. on Saturday evening. Polesitter Helio Castroneves posted the fastest speed at 220.227 mph.[5]

The pole position was won by Hélio Castroneves of Team Penske, driving the No. 3 car. Penske Chevrolets qualified in the first three positions, with Castroneves' teammate Simon Pagenaud starting alongside him in the No. 22 and defending series champion Will Power behind him in position three.

When the field rounded turn three to take the green flag, Castroneves accelerated in turn three. Officials believed Castroneves went too early and waved off the green flag. On the second attempt, Castroneves again accelerated in turn three and the start was waved off a second time. On the third attempt for a start, the green flag was waved and Castroneves was quickly caught by the trailing cars. The cars entered turn one four-wide as Pagenaud and Power pulled to the inside of Castroneves while Josef Newgarden moved to the outside. Newgarden took the lead in turn one, with Pagenaud second and Castroneves third. From his seventh starting position, Justin Wilson had climbed to third by the exit of turn one.

Green flag pitstops began around lap 29, with the race leader Newgarden among the first to pit. Leaving the pits, the left-rear wheel fell off the car of Jack Hawksworth and a caution was waved to retrieve it. The caution rearranged the running order, with Newgarden retaining the lead while Justin Wilson moved to second and Carlos Munoz in third. On the restart, Sébastien Bourdais drifted out of the groove in turn one and lost control. He spun and impacted the wall with the left side of the car.

When the race restarted on lap 43, Wilson drafted past Newgarden and took the lead in turn one. Newgarden repassed Wilson entering turn two and continued to hold the lead for the next 12 laps. On lap 55, Tony Kanaan charged to the lead, passing Newgarden on the frontstretch. Kanaan held the lead until greenflag pitstops began on lap 65. After the cycle of stops, Simon Pagenaud assumed the lead Castroneves and Kanaan in close pursuit. On lap 79, Castroneves took the lead on the frontstretch.

On lap 85, Jack Hawksworth made a late move to pass Charlie Kimball in turn one and both cars collided. They made very light contact with the wall and slid down the track locked together, both drivers making angry gestures at each other as the cars slid. Hawksworth retired from the race while Kimball was able to continue on the lead lap. Exiting his pitstall under caution, Will Power spun and dropped to the rear of the field.

On the lap 93 restart, Kanaan passed Castroneves entering turn one. At the completion of the first lap under green, Graham Rahal and Justin Wilson entered turn three side by side. Tristan Vautier made a late move to the inside of Rahal entering the turn and spun Rahal. Rahal and Vautier impacted the turn three wall. An angry Rahal confronted Vautier on track and voiced his displeasure in an interview with NBCSN.

"(Vautier) says I turned in on him, there's not any space. I mean, we're already two-wide, he knows that, he sees that. But he's not known as the sharpest tool around here... As they say, when you're back with the squirrels, you're bound to get your nuts cracked."

When the race restarted on lap 104, Pagenaud took the lead from Kanaan. One lap later, Sage Karam took the lead and led for two laps before pitting under green, returning the lead to Pagenaud who was quickly passed by Castroneves. Debris from the car of Ed Carpenter brought out another caution on lap 109.

On lap 132, Tony Kanaan clipped the apron in turn two and spun out, impacting the inside wall and breaking the left-front suspension. On the restart, Marco Andretti lost control entering turn two, spun, and hit the wall with the right side.

On lap 152, Ryan Hunter-Reay drafted past Sage Karam and Simon Pagenaud to take to lead on the frontstretch. With 37 laps to go, the ninth caution of the day came out when a fox ran from the infield and crossed the race track at the end of the frontstretch before it jumped over the wall.

On the lap 167 restart, Sage Karam in fourth position failed to accelerate with the leaders and created a major traffic jam on the frontstretch. The cars of Karam, Pagenaud, Chaves, Newgarden, Power, Montoya, and Takuma Sato went seven-wide on the frontstretch, with Sato going from the 12th position to 4th by turn one. Helio Castroneves got too high in turn one and spun into the wall, bringing out the tenth caution of the day.

When the race restarted on lap 173, a tightly packed field entered turn one three-wide for the lead, with Newgarden passing Ryan Hunter-Reay and Takuma Sato for the lead. Exiting turn two later that lap, Sato passed Newgarden for the lead.

Most of the leaders made pitstops on lap 164 and needed to conserve fuel to make the finish. Running a conservative fuel strategy, Sato was passed by Karam for the lead with 25 laps to go. A highly competitive race, Karam's pass of Sato broke the event record of 28 lead changes set in 1973.

With 21 laps remaining, Karam lost control and spun from the lead in turn one. He impacted the wall with the left-front. Debris from the accident fell from the air and hit Justin Wilson on the helmet. Wilson, who had been in the thirteenth position, slid unconscious into the inside wall.

Karam's crash gave the lead to fellow rookie, Gabby Chaves, who was looking to become the first rookie to win the Pocono 500 since Danny Sullivan in 1984. The long caution allowed all cars to make the finish on fuel.

After a lengthy clean-up, the race restarted with seven laps remaining. Chaves led the field for the next two laps. Hunter-Reay passed Sato for second entering turn three sith six laps remaining. Hunter-Reay then drafted off Chaves on the frontstretch and made a slingshot pass entering turn one on the inside. Chaves was quickly passed by Newgarden and Montoya. Exiting turn two with four laps to go, Chaves suffered engine failure, bringing out the 12th caution of the day, breaking a record for most cautions in the Pocono 500 set in 1988.

Ryan Hunter-Reay led the field under caution for the final three laps and scored the victory. It was the 16th of his IndyCar career and second 500-mile victory, after the 2014 Indianapolis 500. His average speed was 146.245 mph. Josef Newgarden, driving the No. 67 Chevrolet for CFH Racing, finished second and led a race-high 47 laps. Points leader Juan Pablo Montoya finished in third.

With 33 lead changes, it was an event record that remained until 2017. There were 12 caution periods for 74 laps, and the race ended under the yellow flag. Between 2013 and 2019, it was the only Pocono 500 with more than four cautions.

Eleven cars were running at the finish, with each being on the lead lap except for Pippa Mann, whose No. 18 Dale Coyne Racing Honda was running in thirteenth place fifteen laps down.
