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.
1980 Spanish Grand Prix
The Spanish Grand Prix was the first race to be affected as part of the FISA-FOCA war. Future races such as the 1981 South African Grand Prix and 1982 San Marino Grand Prix would also see teams not compete as the two organisations competed for control of the sport.
