A Formula 1 season now runs to 24 rounds, but only a handful of Sundays have genuinely changed the sport. Some races set the technical direction; others rewrote safety rules entirely; others swapped the champion's name on the last corner. The ten grands prix below did at least one of those three things.
They span 71 years from Silverstone in 1950 to Abu Dhabi in 2021, listed in chronological order. Each entry recounts what happened that day, lap by lap where it mattered, and separately what it changed in Formula 1 afterwards.
