Potrero de los Funes Circuit

The Potrero de los Funes Circuit (Circuito de Potrero de los Funes) was an Argentine motorsports race track. It is located 14 km from San Luis, capital city of the San Luis Province, Argentina.

History
The circuit was originally constructed in 1978 as a semi-permanent venue, with a length of 6.206 km. It was created by modifying the ring road that encircles Lake Potrero de los Funes at the course's center, and featured substantial elevation changes along with a variety of different types of corners. After hosteing a round of Turismo Carretera on 15 August 1987, but two separate crashes which resulted in the deaths of two spectators and an injured driver led to the track being abandoned.

The track was re-opened in 2008 as a venue for the FIA GT Championship. The circuit was modified, with two chicanes added due to a lack of run-off area as well as the tightening of the final corner to create a safer pit entry – extending the circuits' length to 6.270 km. Belgians Bert Longin and Anthony Kumpen won the first San Luis 2 Hours in their Saleen S7R. The circuit went on to host two rounds of the FIA GT1 World Championship in 2010 and 2011, along with local series such as TC2000 and Turismo Nacional.

The final round held at the circuit was in 2018 for TC2000. Following years of disuse, the circuit was dismantled in 2024.
