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.
1962 Mexican Grand Prix
The I Gran Premio de Mexico (or 1st Mexican Grand Prix) was held on 4 November 1962 at the Magdalena Mixhuca circuit, Mexico City. The race was a non-championship event run to Formula One rules and attracted a large entry, including many top teams and drivers. The race was run over 60 laps of the main circuit, and was eventually won by Jim Clark and Trevor Taylor, sharing a drive in a Lotus 25. The race meeting was marred by the death during practice of local driving prodigy Ricardo Rodríguez. The circuit would later be renamed the "Autódromo Hermanos Rodríguez" to honour him and his brother Pedro.
