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.
German Grand Prix
The first national event in German Grand Prix motor racing was held at the AVUS (Automobil Verkehrs und Übungs-Straße (Automobile Traffic and Practice Road)) race circuit in southwestern Berlin in 1926 as a sports car race. The AVUS circuit was made up of two 6-mile straights combined with two left-hand hairpins at each end. The first race at AVUS, in heavy rain, was won by Germany's native son, Rudolf Caracciola in a Mercedes-Benz. The event was marred by Adolf Rosenberger's crash into one of the marshals' huts, killing three people. The AVUS circuit was considered extremely dangerous even back then- so the event was moved. The German "Grand Prix" became an official event in 1929. Although it was raced on in the non-championship AVUS-Rennen in the 1930s which saw some of the fastest road races ever held, the Grand Prix would not return to AVUS until 1959 for a one-off appearance.
