Neither manufacturer was deemed to have exceeded cost cap restrictions but both had documentation issues that earned penalties.

Honda was given a US$600,000 fine because its cost cap calculations incorrectly represented excluded costs or adjusted costs. Alpine was fined US$400,000 because it was late to file documentation that did not include necessary information.

Both infractions were considered minor and each team was handed an Accepted Breach Agreement. Both cases are considered closed.

In addition to the US$1 million in fines, both teams also must pay administrative costs incurred during the investigation.

The 2023 season was the first where engine manufacturers were required to work under a cost cap. Because Honda and Alpine were considered to have made procedural errors, F1 has determined that all 10 teams operated within cost cap limitations.
