# 1981 Brazilian Grand Prix

The 1981 Brazilian Grand Prix was the second race of the 1981 Formula One World Championship and was held on 29 March 1981 at Jacarepaguá in Rio de Janeiro, Brazil. Formula One moved to the Jacarepaguá circuit in Rio de Janeiro from the Interlagos circuit in São Paulo, after safety concerns with the long Interlagos circuit and the growing slums of São Paulo being at odds with the glamorous image of Formula One.
The Argentine driver Carlos Reutemann won the race in contentious circumstances; he ignored his pit signals to give up the lead to his teammate and team leader Alan Jones. Jones, who finished second, did not show up on the podium afterwards.
