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.
Grand Prix motor racing
The only race at the time to regularly carry the name Grand Prix was organised by the Automobile Club de France (ACF), of which the first took place in 1906. The circuit used, which was based in Le Mans, was roughly triangular in shape, each lap covering . Six laps were to run each day, and each lap took approximately an hour using the relatively primitive cars of the day. The driving force behind the decision to race on a circuit - as opposed to racing on ordinary roads from town to town - was the Paris to Madrid road race of 1903. During this race a number of people, both drivers and pedestrians - including Marcel Renault - were killed and the race was stopped by the French authorities at Bordeaux. Further road based events were banned.
