Spanish Grand Prix
The first Spanish Grand Prix in 1913 was not actually run to the Grand Prix formula of the day, but to touring car rules, taking place on a 300-kilometre road circuit at Guadarrama, near Madrid, on the road to Valladolid.
Brazilian Grand Prix
A Brazilian Grand Prix was first held in 1972 at Interlagos, although it was not part of the Formula One World Championship. Typical of European motorsports at the time, this race was done as a test to convince the FIA if the Interlagos circuit and its organizers could capably hold a Grand Prix. Like most major circuits used for Grands Prix in Latin America such as the Hermanos Rodríguez Autodrome in Mexico City and the Almirante Brown Autodrome in Buenos Aires, Interlagos was (and still is) located in the confines of a sprawling urban neighborhood in a very large city. The following year, however, the race was first included in the official calendar, and it was won by defending world champion and São Paulo native Emerson Fittipaldi. In 1974, Fittipaldi won again in rain soaked conditions, and the year after, another São Paulo native, Carlos Pace, won the race in his Brabham, followed by Fittipaldi. 1977 was won by Reutemann, but the drivers began complaining about Interlagos's very rough surface, and the event was then relocated for a year to the new Jacarepaguá circuit in Rio de Janeiro.
