Budget cap regulations are significantly influencing technical, sporting, and financial legislations. The FIA, to maintain its role as the regulatory body, intervened several months ago regarding various divisions within teams. In fact, nearly all current F1 teams have external projects alongside those in the premier open-wheel championship. However, in 2024, the new TD045 directive will be introduced for power units, further restricting work on the engines.
The introduction of the spending cap in F1 has imposed budget limits on teams each season, aiming to narrow the financial gap among participants. Nevertheless, larger teams have vastly greater resources and funds compared to those at the bottom of the standings.
In recent years, a loophole has been frequently exploited, redirecting some personnel to other external technical projects, leveraging the know-how gained in F1 to expand their business ventures. Notable examples include Ferrari with its GT and Endurance division, Red Bull with Advanced Technology, McLaren with Applied Science, Aston Martin with the recently established Performance Technologies, and Mercedes with its GT department.
These corporate partitions raised suspicions among other teams about the improper use of these divisions to delve into F1-related matters without violating the Budget Cap.
Due to suspicions about these information movements, the FIA decided to implement a new technical directive midway through the season. The arrival of TD045 officially solidifies the federation’s move regarding potential information exchanges between internal divisions. This directive stipulates that teams remain free to transfer information between various departments, but any element related to F1 must be strictly included in the budget. This directive eliminates the teams’ “free” resources.
While initially applied only to aerodynamics in the summer, with the latest technical regulation update, it now extends to power units.

In the financial regulation section, a new article related to power units is noted. This section legislates even more strictly on power unit activities that were previously considered “external.” With the “new” TD045, all activities must now be accounted for in the season’s financial records, both for 2024 and 2025.
In section 4.1, paragraph n of the regulation, the FIA states, “If, during the entire year ending on December 31, 2024, the conditions that led a Power Unit Manufacturer to believe that a certain activity not related to the Power Unit undertaken in the previous Complete Year Period (referring to the previous season) have changed following the introduction of TD045, all costs related to such activity that were excluded in the previous year’s period must be included in the relevant costs.”
