Dario Franchitti, who leaped into the top eight on the time chart in the final seconds of practice to qualify for the heat race, passed Marco Andretti on Lap 8 of 30 and went on the claim the pole for the 250-lap race under the lights June 23.
It was the second consecutive week that Franchitti has started on pole, and was the 28th of his Indy car career (passing Al Unser for seventh on the all-time list).
Results of the second practice session determined the fields for the 30-lap qualifying races. The top eight comprised Race 3, while Race 1 consisted of even-numbered positions in practice to determine the even-numbered spots in the starting lineup starting from 10th down. Race 3 followed the same format for odd-numbered cars.
Franchitti led Helio Castroneves, driving the No. 3 Penske Truck Rental car, to the start-finish line of the .894-mile track by 1.4671 seconds. It will be the second front-row start of the season and the fourth at Iowa Speedway for Castroneves, who won the opener at St. Petersburg.
Andretti, who topped the time chart in the two practice sessions, and Andretti Autosport teammate James Hinchcliffe will be on Row 2.
Team Penske teammates Ryan Briscoe and Will Power, the IZOD IndyCar Series championship points leader, will start on Row 3. Ryan Hunter-Reay, the winner last week at Milwaukee, will be on Row 4 with Scott Dixon.
Tony Kanaan and Graham Rahal were the other heat race winners to qualifying ninth and 10th, respectively, but they’ll incur 10-grid spot penalties for unapproved engine changes. Alex Tagliani and Josef Newgarden will take their spots on Row 5.
Also on June 22, Tristan Vautier’s first qualifying lap of 160.066 mph on the .894-mile Iowa Speedway oval paved the way to a two-lap average of 159.973 mph (40.2368 seconds) and the pole position for the Firestone Indy Lights Sukup 100 on June 23.
Vautier, driving the No. 77 Mazda Road to Indy/Sam Schmidt Motorsports with Curb Agajanian car, earned his third pole of the season — and second in a row. He went on to win the race last weekend at the Milwaukee Mile.
Esteban Guerrieri will start on the front row for the third time this season, posting a qualifying speed of 159.597 mph (40.3316 seconds). He started from the pole in the 2011 Firestone Indy Lights race at Iowa Speedway.
Victor Carbone, the final qualifier, jumped to third in the No. 3 Mav TV/Nevoni/SSM with Curb Agajanian car to provide the sixth 1-2-3 starting lineup for the team in Firestone Indy Lights. Sebastian Saavedra will join Carbone on Row 2 in the No. 27 Team AFS car.
