The1000 km Buenos Aires was anendurancesports car andstock car event held inBuenos Aires,Argentina. The race mostly run on theAutódromo Oscar Alfredo Gálvez, although it ran on the Costanera circuit in 1957. Besides a single race inCaracas,Venezuela, it was the only annualSouth American race in the history of theWorld Sportscar Championship.
In1953,Formula One visited the newly built Autódromo in the center of Buenos Aires for theArgentine Grand Prix. The race was successful enough for Formula One to return the following year, and it was also decided that the newly formedWorld Sportscar Championship would add the track to their schedule as a traditional season-opening event. Following the1000km Nürburgring the previous year, this would make the Buenos Aires round only the second 1,000 km (621.4 mi) event in the series history.
A 9.5 km (5.9 mi) circuit using long sections of theAvenida General Paz highway attached to the Autodromo section used only by Formula One would be used for the first 1000 km event.[1] In 1955, an even longer section of theAutopista General Pablo Riccheri route would be added, making the circuit 17.1 km (10.6 mi) in length before it returned to its original size once again in 1956.[2] The event would move however in 1957, to the Costanera circuit before returning to the Autodromo in 1958.[3] One final appearance was made by both Formula One and sports cars in 1960 before both chose not to return to Argentina for the time being.
The 1000 km event would return once more in 1970, as a non-championship exhibition round. The Autodromo had been expanded in 1968 to allow for a 6.1 km (3.8 mi) circuit and eliminating the use of public highways.[4] World Championship status would return again in 1971 while Formula One would also test the re-addition of the Argentine Grand Prix by holding their own exhibition race. The circuit would be modified again in 1972, shortening the lap to 6.0 km (3.7 mi) for the sportscars,[5] while the Argentine Grand Prix officially returned to the Formula One calendar where it would stay for nearly a decade. The 1000 km sports car event would however be abandoned after the 1972 running, with the series eliminating several fly-away events in the coming years to cut costs.
In 2017,Turismo Carretera revived the event as one of theirCarreras Especiales ("special races") to celebrate the 80th anniversary of the category. This version of the race was held only twice, in 2017 and 2018, with one win apiece going toFord andChevrolet.[6]
The event was dominated byFerraris, winning five out of the six runnings in the race's first incarnation before winning the final event once again in 1972. AmericanPhil Hill would be the only driver to win more than once.
