Formula One regulations

The Formula One regulations, made and enforced by the FIA, are rules that govern car specifications, racing procedures, scoring, and penalties in Formula One. The primary goals of the Formula One regulations are to ensure driver safety and fairness in competition. As of 2026, the regulations are designed with an additional goal of promoting environmental sustainability in the sport.

There are two main types of regulations; technical and sporting. Technical regulations are related to car specifications, such as the chassis or the engine. Meanwhile, sporting regulations involve race procedures and set rules that pertain to the sport as a whole. There are also financial regulations that place restrictions on the budgets of teams and power unit manufacturers, and operational regulations that dictate factory testing procedures.

The regulations in Formula One are updated by the FIA on a yearly basis. Typically, only minor changes are made, such as in order to close loopholes, improve safety, or adjust the scoring system. However, major regulation changes have also occurred, such as in 2014, with the introduction of 1.6-litre V6 turbo-hybrid engines, and in 2026, with the significantly increased electrification of the engine and the introduction of new power unit and aerodynamic modes. Such major regulation changes are announced years in advance, to give teams and manufacturers time to plan and design the new cars.
