The 1983 Brazilian Grand Prix was a Formula One motor race held at Jacarepaguá on 13 March 1983. It was the first round of the 1983 Formula One season.
Andrea de Cesaris was excluded after failing to stop for a weight check during Saturday qualifying.
Keke Rosberg's pole position was the last for the Cosworth DFV engine, and the last for a car with a naturally aspirated engine until turbos were banned in 1989. It was also the last pole position for Cosworth until 1993.
The race marked the debut in the Formula One World Championship debut for American driver and future Indianapolis 500 winner Danny Sullivan, Italian driver Corrado Fabi, motorcycle road racing World Champion Johnny Cecotto, British constructor RAM.
Elio de Angelis qualified for the race in his Renault turbo-powered Lotus 93T, but switched to the team's spare car, a Cosworth DFV-powered Lotus 92, when the Renault unit failed on the warm-up lap. This was deemed illegal and so he was disqualified.[1]
Rosberg was disqualified for a push start in the pits, after his car momentarily caught fire during refueling. It was the second consecutive Brazilian Grand Prix in which Rosberg was disqualified from second place. The drivers finishing behind him were not promoted, so the six points for second place were officially not awarded.[2]
