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. For the 1948 Grand Prix season, the race was moved to the Palermo circuit where it would remain to host six of twelve "Peron Cup" races until the end of 1950. 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.
