After a six-year break and General Juan Peron in office, racing resumed at Retiro in 1947 with the start of the South American "Temporada" Grand Prix series to be contested twice a year under Formula Libre regulations.

Italian Luigi Villoresi won all 1947 Temporada events.

The race regularly attracted Brazilian and European drivers and also Argentine drivers such as Juan Manuel Fangio and José Froilán González were now competing in Europe on a regular basis.

In 1951, the Costanera Norte circuit would host its last three Grand Prix events before the 1951 completion of the Autodromo 17 de Octubre (October 17), a purpose-built circuit for major Grand Prix series which would host various editions of the Buenos Aires Grand Prix from 1952 until 2009 with the exception of the 1956 event held at the General San Martin circuit in Mendoza.

In 2023, the name was revived for the Argentine stock car racing championship Turismo Carretera.
