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.
Autódromo Hermanos Rodríguez
Built in the Magdalena Mixhuca public park in 1959, the circuit hosted its first Formula One Grand Prix in 1962, as a non-Championship race. The following year the Mexican Grand Prix became a full World Championship event. The circuit remained part of the F1 calendar through 1970, when spectator overcrowding caused unsafe conditions. When the track re-opened in 1986, the circuit boasted a new pit complex, as well as improved safety all around. In 2001 CIE and Forsythe Racing tasked D3 Motorsport Development with revamping the circuit. A redesign to include the Foro and a complete upgrade of the circuit was done. It saw a record crowd of 402,413 people attend a round of the CART Championship in 2002. As of 2018, the Autódromo Hermanos Rodríguez has been the only venue for the F1 Mexican Grand Prix.
