2031 Formula One season

The  will be the 20th running of the Formula One championship. Three championships will be up for grabs as the Championship of Drivers, Championship of Constructors and Championship of Engines.

Calendar
No calendar has been announced for the season yet. In recent previous years the calendar was run fairly strictly to comply with the Grand Prix Calendar Cycle last modified in 2025, however the cycle was unofficially abandoned for 2030. It is reasonable to assume that the following Grand Prix will feature somewhere on the calendar:
 * 🇧🇪 Belgium Belgian Grand Prix at Circuit de Spa-Francorchamps
 * 🇧🇷 Brazil Brazilian Grand Prix at José Carlos Pace
 * 🇮🇹 Italy Italian Grand Prix at Autodromo Nazionale Monza
 * 🇯🇵 Japan Japanese Grand Prix at Suzuka Circuit
 * 🇲🇨 Monaco Monaco Grand Prix at Circuit de Monaco
 * the United Kingdom United Kingdom Grand Prix at Silverstone Circuit
 * the United States United States Grand Prix somewhere

Signed teams and drivers
The FIA announced another change to the numbering system for this season. Numbers will be assigned as normal, however teams chose to either use their assigned numbers, or designate their two cars specific custom numbers as long as they are not in the list of existing designated numbers. Provisionally, available numbers for this season are 26–99, 100, 110, 120, ..., 990.

Each year the teams will chose whether to use their FIA-assigned numbers or their custom numbers. They automatically gain the right to change their custom numbers at 10 year intervals starting 2040. Otherwise, they can apply to change their numbers and the FIA will grant their application at their discretion.

Of significant note, Toyota's controlling stake in Santander is up for renewal, as are Honda's deals with South McLaren, Minardi and Janz, as well as Ferrari's with North McLaren.
