The 20 Formula One Argentine Grand Prix races were held in the "Autódromo" between and . Formula One used a number of different configurations—the No.2 circuit was used from 1954–1960, the No.9 circuit was used from 1971–1973, and the very fast No.15 layout was used from 1974–1981 which added 2 long straights and a long third corner between the two straights often taken in top gear flat out, which provided an exciting view for spectators, especially when the cars exited the third corner often on the brink of spinning off or crashing at 305 km/h. Going through the section, the cars were flat out for 40 seconds. The Argentine Grand Prix was dropped from the 1982 calendar because of Argentina's invasion of the Falkland Islands and Carlos Reutemann's sudden retirement after the 1982 Brazilian Grand Prix. The twisty No.6 configuration, though using S de Senna instead of Tobogán, was used from 1995–1998, but that version of the circuit was not popular with Formula One. After the 1998 race, there was no money for the race to be held and it was dropped.
