DETROIT -- Graham Rahal of Rahal Letterman Lanigan Racing set a track record and earned the pole for Saturday's Detroit Grand Prix IndyCar race.
Rahal covered the 2.36-mile, 13-turn temporary road course in 1 minute, 13.9681 seconds at 114.966 mph. His time from the first round of qualifying stood up after IndyCar officials wiped out the fastest lap turned by Helio Castroneves when he was penalized for not slowing down during a caution.
The Team Penske driver had turned a lap of 1:13.8901. His second-fastest lap time of 1:14.0414 was still good enough to put him on the outside of Row 1.
Castroneves was the only Chevrolet to crack the top six qualifying positions. The Hondas of Indianapolis 500 winner Takuma Sato and Alexander Rossi will start in the second row, followed by the Hondas of James Hinchcliffe and Scott Dixon.
