Brabham won 4 races out of 15, and the world title went to Nelson Piquet.
The title was decided in round 15 – South African Grand Prix.
In 1983 the rules made flat floors compulsory, and turbo engines finally took over. Alain Prost won four races for Renault and led the championship for most of the season.
Nelson Piquet, in a Brabham with a BMW turbo engine, won two of the last three races and at the finale in South Africa became champion for the second time — two points ahead of Prost, who retired with a turbo failure. It was the first title won with a turbo engine.
