The Lago Potrero de los Funes circuit is an Argentine motorsports race track originally constructed in 1987, and rebuilt in 2008. It is located 14 km (8.7 mi) from San Luis, capital city of the San Luis Province, Argentina. The circuit is semi-permanent, with a length of 6.270 km (3.896 mi). It was created by modifying the ring road that encircles Lake Potrero de los Funes, at the course's center. The circuit has received very high praise from the drivers for its substantial undulations and numerous high speed corners and bends, which provide a great driving challenge.
