Autodromo Termas de Rio Hondo ARGENTINA
The Autódromo Termas de Río Hondo is a road course located just outside the city of the same name, in the province of Santiago del Estero. It nestles alongside the banks of the artificial Río Hondo lake.
The circuit originally opened in 2008, having been built by the provincial government at a cost of 144 million pesos. The traditional Turismo Carretera series drew a crowd of over 65,000 spectators for the inaugural meeting on May 11, 2008, nearly a quarter of a century after the series had last visited the area on a temporary road course. The TC2000 touring car series and local Formula Renault have also competed at the circuit, which was among the longest in Argentina, with a main straight of 1350 metres. Varients with a chicane halfway along the main straight and a short circuit bypassing the second half of the circuit were also utilised.
