Autódromo Ciudad de Rafaela, Argentine racetrack

Autódromo Ciudad de Rafaela is a motorsport racing track located in Rafaela, Argentina, designed for national racing events. The facility features an asphalt circuit with pit buildings, grandstands, and safety barriers that accommodate different racing categories.

The Autódromo Ciudad de Rafaela was built in 1952 on a dirt surface and inaugurated in 1953 with a Turismo Carretera race won by Juan Gálvez. It was paved in 1966, then widened and repaved in 1971 for the USAC Rafaela Indy 300, where Lloyd Ruby set the lap record and Al Unser won both heats. The 500 Millas Argentinas were held there from 1954 to 1975.

The oval measures 4,624 metres, with two long straights and banked curves at 15% slope; the three chicanes are the slowest points. The main straight and the inner mixed layout connect the two straights, so spectators can follow cars from several spots. The perimeter is closed by a concrete wall.

The oval measures 4,624 metres, making it the longest oval circuit still used for racing anywhere in the world. Its banked curves have a 15% slope and are 18 metres wide, rebuilt for the 1971 Rafaela Indy 300.
