How this is measured
Share of the races a driver started in one season that they won. A driver needs starts in at least half of the season’s championship rounds, so a one-race winner does not top the list; the career win rate page uses a fixed 20 starts, which would rule out every driver in the seven-round 1950 season. For the current season the half is measured against the full calendar, not the races held so far, so a driver only appears once enough of the season has been run. A driver who won every race they started, as Alberto Ascari did in 1952, scores 100%.
- A start is a race entry that took the start. Entries recorded as did not qualify, did not pre-qualify, failed the 107% rule, or withdrew are excluded.
- The 1950–1960 Indianapolis 500 rounds counted towards the world championship but were run to American rules with roughly 33-car grids and almost no overlap in entrants. They are excluded from every leaderboard on this site.
- The current season is included, so these figures change after every Grand Prix.
