Power had a lap of 1 minute, 21.4045 seconds on the 2.5-mile, 11-turn Anhembi circuit on the streets of South America’s biggest city, less than half a tenth of a second ahead of Franchitti.
Scott Dixon, Franchitti’s Chip Ganassi Racing teammate, will start third.
It was Power’s second pole of the season and second in a row in Sao Paulo. His lap on Saturday eclipsed the previous track qualifying record.
FINED FOR TWEET: IndyCar fined Panther Racing owner John Barnes and placed him on probation until the end of the year for posting a critical comment on Twitter.
IndyCar said Saturday that Barnes was fined $25,000 and put on probation until Dec. 31 for using “improper or disparaging language in reference to IndyCar.”
Barnes can appeal the penalties.
He admitted in a statement he “should have chosen a more private forum to voice my opinions.”
The Panther owner tweeted on Thursday: “Today is the day to resolve TURBOGATE! I hope (at)indcar gets their act together. It has been embarrassing.”
He was referring to a hearing to decide whether Honda would be allowed to make changes to its turbochargers, which eventually happened.
Panther Racing uses engines from Chevrolet, which had appealed a decision by IndyCar allowing the changes that eventually added power to the Hondas.
X GAME DRIVER DEBUT: Friday night’s Nationwide Series race in Richmond, Va., marked the debut of X Game star Travis Pastrana in the series.
After starting 25th, he climbed into the top 20 late in the race before getting caught with a speeding penalty on pit road.
The pass through penalty hurt, and he dropped to 22nd.
Pastrana was supposed to make his debut last summer at Indianapolis, but he broke his right ankle two days before the race.
