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.
Mexican Grand Prix
There had been a number of attempts to bring the Mexican Grand Prix back on the F1 calendar. American IndyCars arrived for a brief two-year visit in 1980 and 1981, racing as the Gran Premio Tecate on the Magdalena Mixhuca track now named for Mexico's two lost racing heroes, Autódromo Hermanos Rodríguez. The event was dominated by Rick Mears. A number of years later, work began on rebuilding the Hermanos Rodríguez circuit with much improved organisation. The circuit's layout was slightly shorter, the Peraltada's banking had been eased and the circuit was generally much safer than it had been. The Grand Prix returned in 1986 where the race played host to Austrian Gerhard Berger's first race win in his Benetton B186, in a race where an ill Berger outlasted his opposition as tyre problems struck most of the field. The circuit was still very rough and bumpy, however. 1987 saw the race being run in two parts. It was stopped around mid-distance when Briton Derek Warwick crashed heavily coming out of the Peraltada. Brazilian driver Nelson Piquet actually finished first on the road, but because his Williams teammate Nigel Mansell was 30 seconds ahead when the first race ended, Mansell kept Piquet in sight and won the race on corrected time.
