The first champion was Eduardo Pedrazzini driving for Ford. Other champions have included 5 time Formula One winner, Juan Manuel Fangio and Ferrari's first formula one champion Jose Froilan Gonzalez. The original governing body of Turismo Carretera the ACA became the ACTC in 1979 in response to the growth and success of the championships. Despite this change there has been no major change in the running of Turismo Carretera which is why it is still classed as the same championships.
