Norris takes a nine-point lead into Sunday’s main race, with Piastri spinning on lap six after clipping a wet kerb at an overcast and damp Interlagos.
Mercedes duo Kimi Antonelli and George Russell completed the podium in a sprint that was red-flagged after Piastri and Alpine’s Franco Colapinto exited the 100km dash.
Norris, who went into this weekend with a one-point lead over Piastri, will be hoping to keep up the momentum in qualifying for Sunday’s race later.
The 24-lap dash finished under a yellow flag after Gabriel Bortoleto’s Sauber suffered a big crash.
Max Verstappen crossed the line in fourth to leave Red Bull’s four-time defending champion 40 points behind Norris going into the fourth-to-last race of the season.
