Roger Penske's last win with the open-wheel cars at Watkins Glen International Raceway was in 1981.
His teams remedied that with Will Power capturing the pole and taking the win in the Camping World Grand Prix at the Glen.
Ryan Briscoe wheeled his team Penske car to second place, followed by Dario Franchitti.
It was a beautiful day in the finger-lakes region of New York as the Izod IndyCar drivers turned right and left on the tough 3.4 mile, 11-turn road course.
Power now has a 32 point lead in the standings over Franchitti.
The winner of today's race has won on other circuitous courses this year. He is the only IndyCar driver to do so.
After the race Power said, "I wanted it really bad; I really wanted to win." He added, "It was a difficult race, but it was great. I loved it."
Once again Raphael Matos secured a fourth-place finish despite losing his telemetry early in the race, which affected his fuel mileage readings.
Mario Moraes finished fifth in the No. 32 KV Racing Technology car.
Helio Castroneves started in the front row, but suffered a flat left-rear tire after being clipped by the front wing on Scott Dixon's car during the seventh lap.
Said Castroneves: "I think I proved I was the fastest car on three wheels out there."
He was able to recover and finish in ninth place.
Danica Patrick finished ahead of the other two women drivers in the race. She began in the 21st position and finished in 20th place, maintaining 11th place in the points standings.
Milka Duno was still running though several laps down and finished in 23rd position.
Simona deSilvestro completed 38 out of the 60 laps, but was out of the race because of damage to her car.
