Championship background
Jack Brabham arrived at round 9 leading the 1966 F1 World Championship on 39 points, with Jochen Rindt on 22. Brabham – Repco headed the constructors’ standings after the preceding race with 40 points.
Race entries
Ferrari did not attend the finale. Lotus entered Clark, Arundell and local favourite Rodriguez, while Cooper added Solana alongside Surtees and Rindt. Eagle, Honda and BRM continued developing their three-litre machinery, with the city’s altitude adding further complications to fuel mixture, cooling and engine performance.
Friday morning familiarisation
A short opening period allowed drivers to begin adapting their engine settings to the thin air before official afternoon practice. Correct mixture was especially important at this venue, where reduced air density affected power and cooling. The running was preparatory rather than a separate qualifying contest.
Friday timed practice
Brabham narrowly bettered Clark’s time near the end, but the session brought extensive mechanical trouble. Clark’s H16 failed violently, forcing an engine change, and Surtees battled fuel-system faults and high temperatures. Honda experimented with suspension settings, while Gurney struggled with oil discharge and fuel delivery. Ireland damaged his car after an encounter with a stray dog.
Saturday final qualifying
Surtees took pole through short runs despite a failing head gasket and fuel vaporisation. Brabham also required an engine change. Honda continued searching for workable handling, and Eagle’s oil problems persisted. Spence suffered a heavy accident after a wheel assembly came loose. Clark’s running was deliberately limited with the replacement H16, leaving many teams facing a difficult evening of repairs.
Qualifying Classification
The best lap from the two afternoon timed sessions decided the grid. The morning familiarisation period was separate from those qualifying sessions.

What happened in the 1966 Mexican Grand Prix?
Ginther made a strong start in the Honda, but Surtees soon established the pace. Once he passed Brabham, the Cooper driver controlled the race, making excellent use of a car that had required substantial attention during practice.
Clark suffered gearbox problems and both works BRMs retired. Ginther’s own difficulties prevented a sustained challenge, leaving Brabham as Surtees’s closest opponent. The champion reduced the gap late on but could not reverse the result.
Surtees won ahead of Brabham and Hulme, with the victory carrying him past Rindt into second in the championship. It was Cooper’s first win with Surtees and a satisfying conclusion to a season in which he had changed teams midway through the campaign.
After the race, Jack Brabham headed the drivers’ standings with 42 points, followed by John Surtees on 28. Brabham – Repco led the constructors’ table on 42, with Ferrari on 31.
