GoPro Grand Prix of Sonoma
• What's at stake: Race 16 of the Verizon IndyCar Series season, which will determine the champion. Double base points add intrigue as will the new primary and alternate tires supplied by Firestone Racing, which provide more grip on the abrasive racing surface but degrade quicker than a harder compound. Team Penske’s Juan Pablo Montoya leads the championship standings by 34 points over Graham Rahal of Rahal Letterman Lanigan Racing. There are six drivers eligible for the title. It is the 10th consecutive year that the champion will be decided in the season finale.
• Qualifying results: Power resets year-old track record ... Reigning series champion Will Power, who has won at Sonoma Raceway three of the past five years, broke the track record in the Firestone Fast Six qualifying session to earn the Verizon P1 Award. It was his sixth pole earned this season.
