Most F1 Race Entries by a Constructor

How this is measured

• This counts race entries rather than starts, so it includes entries that failed to qualify.
• 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.
• Constructors are counted under the name that appears in the results rather than as continuous franchises. Combined records across rebrands are on the legacy franchise pages.
