SAO PAULO (AP) -- Two-time race winner Will Power was fastest in the first practice session for Sunday's Sao Paulo 300, edging Chip Ganassi teammates Dario Franchitti and Scott Dixon.
Power had a lap of 1 minute, 22.387 seconds in his Penske at the 2.5-mile, 11-turn Anhembi circuit on the streets of South America's biggest city. He was just .007 in front of three-time defending IndyCar series champion Franchitti.
Dixon finished .398 behind Power, who is trying to win his third straight race in Sao Paulo.
Simon Pagenaud was fourth and Josef Newgarden fifth in a session held in overcast skies but dry conditions.
Rain affected the first two races won by Power in Brazil. The inaugural event was postponed for a day and last year the race was cut short.
