1975 Spanish Grand Prix
It was the 21st Spanish Grand Prix since the race was first held in 1913. It was the fourth, and last, Grand Prix to be held on the Montjuïc street circuit. The race was shortened to 29 of its scheduled 75 laps, a race distance of 109 kilometres. The race was won by German driver Jochen Mass driving a McLaren M23. It would be the only Formula One win of his career. Mass had just a second lead over the Lotus 72E of Belgian driver Jacky Ickx when the race was declared. Argentine racer Carlos Reutemann was declared third in his Brabham BT44B, a lap behind the race leaders after a penalty was given to Jean-Pierre Jarier. This was the final win by a German driver until Michael Schumacher won the 1992 Belgian Grand Prix.
Montjuïc circuit
By 1908 international motorsport was conducted at the Circuit Baix Penedès with the "Copa Catalunya". In 1923 the first Great automobile Prize of Spain in the permanent Sitges Terramar circuit was run near Barcelona. In 1932 a race was held on a street circuit with the start in the Montjuïc Park, wooded parkland on a hill above the city's harbour. The course of the 1933 east circuit of that race became the Montjuïc Circuit proper, holding the Penya Rhin Grand Prix.
