Autódromo Internacional Nelson Piquet is a race course in Brasília, the capital of Brazil. 5.476 km in length, the name of the circuit was originally Autódromo de Brasília when it opened in 1974, but it was later changed to honor Formula 1 World Champion Nelson Piquet. The circuit brought a non-championship Formula One race to Brasília one week after 1974's official Brazilian GP, known as the Presidente Medici GP won by Emerson Fittipaldi.
From 1995, the circuit was leased to NZ Empreendimentos, one of Nelson Piquet's companies, by the government of the Brazilian Federal District. But, in 2006, the Federal District regained the control to manage the circuit due to NZ Empreendimentos' lack of attention to the track's management.
