The championship was contested over five events held in five different countries across South America, running from March to November.

The championship was won for the sixth time by Paraguayan Skoda driver Gustavo Saba. Saba was second at the opening event in Paraguay before winning rallies in Argentina, Brazil and Bolivia, wrapping up the championship early.
