Formula Twelve (more commonly known as Formula 12 or F12) is the highest class of international racing for open-wheel single-seater formula racing cars sanctioned by the Torland Auto Racing Association (TARA). The TARA Formula Twelve World Championship has been one of the premier forms of racing in Torland since its inaugural season in 1972. A Formula Twelve season consists of a series of races, known as Grands Prix. Grands Prix take place in multiple states and areas around Torland on either purpose-built circuits or closed public roads.

A points system is used at Grands Prix to determine two annual Championships: one for the drivers called the Worthy Cup, and one for the constructors (the teams) called the Calhoun Cup. Each driver must hold a valid Super Licence, the highest class of racing licence issued by TARA, and the races must be held on tracks graded “1”, the highest grade-rating issued by TARA for tracks.

Formula Twelve cars are some of the fastest regulated road-course racing cars in the world, owing to very high cornering speeds achieved through generating large amounts of aerodynamic downforce. Much of this downforce is generated by front and rear wings, which have the side effect of causing severe turbulence behind each car.

The average annual cost of running a team, including designing, building and maintaining cars, salaries, and transport make the sport very difficult to participate and sustain.
