Race summary
The race took place on the evening of Saturday June 6, 2015 and was the fastest IndyCar Series race ever run at the Texas Motor Speedway with an average speed of 191.940 mph. It was a relative clean contest with only one caution occurring between laps 84 to 96, which was due to non-contact debris on the front stretch of the track, during the entire 248 lap race. Pole driver Will Power had the lead for the first 7 laps of the race, when Simon Pagenaud took the lead from him and held it for the next 59 laps of the race. Multiple pit stops by others further back in the field to make wing and tire adjustments shuffled the order and put several drivers one to three laps down. Finding the right balance of downforce and tire wear and press would prove pivotal in the race. In lap 67, Tony Kanaan took the lead. During the caution beginning in lap 84, pretty much the entire field pitted, and pit times resulted in a major reshuffling of order once again with Juan Pablo Montoya holding the lead when the race resumed on lap 96, with Kanaan retaking the lead on lap 103.

As cars pitted for fuel beginning in lap 138, the lead was again reshuffled, with the lead passing to Scott Dixon, Hélio Castroneves, James Jakes and then back to Dixon. Another round of pitting for fuel again reshuffled the lead over a ten lap period, with Kanaan, then Castroneves and then Marco Andretti taking the lead. Dixon re-took the lead on lap 194 and would maintain lead for the rest of the race with the except of his taking his final pit stop for fuel on lap 228 end up having the lead for a total of 97 laps, eclipsing his season total of 59 in laps led in one race. He would go on to win the race, which his Chip Ganassi Racing teammate Kanaan taking second, and Castroneves taking the third podium position for Team Penske. The top 4 finishers were all Chevrolet cars which dominated the race and the top finishers suggest high downforce will be the way to success on oval courses for the remainder of the season.
