Carlos Reutemann won the F1 Brazilian Grand Prix at the Jacarepagua circuit, ignoring Williams team orders to let teammate Alan Jones pass for the win. With 7 laps to go in the scheduled 63 lap race, a pit board was displayed to Reutemann telling him to let Jones by. The sign was displayed 3 more laps, but Reutemann wound up taking the checkered 4 seconds ahead of defending World Champion Jones when the race reached the 2 hour time limit one lap early. Reutemann later insisted he was going to wave Jones by on lap 63, a lap which never came.
