Formula 4

The category was created in March 2013[1] by the Fédération Internationale de l'Automobile (FIA)—the International sanctioning and administrative body for motorsport—after approval by the World Motor Sport Council as an entry-level category for young drivers, bridging the gap between karting and Formula 3.

Initially, these Formula 4 championships started in 2014 as a single-make category before the regulations were opened up to multiple chassis and engine manufacturers.

The engines are equalised so that no one Formula 4 championship is faster than the others, with the long-term intention being to bring the cost down to under €100,000 per year to compete.

According to the homologation requirements a FIA Formula 4 engine must last at least 10,000 km and have a maximum purchase price of €14000.

[5] Formula 4 is the first step out of karting on the FIA Global Pathway, and by design has the least performance of any of the cars in it.

[13] Drivers participating in these series can receive FIA Super Licence points, which are required to drive in Formula One.

Drivers use slightly modified Tatuus F4-T421 chassis with Autotecnica 1.4 litre turbocharged 4-cylinder engines.

The series champion will win a Formula 4 United States Championship ride for the ensuing season.

Chassis are typically locally produced such as Xpit and Gamma and cars are fueled by methanol.

The races are co-organized with the Austrian, Czech and Hungarian national championships, as well as the Italian Topjet F2000 Trophy and Austrian Drexler AFR Pokale, the latter allowing cars of similar performance to FIA cars in its F4 division, such as Formula BMW, Czech F1400 and ADAC Formel Masters.

The winner of the USF Pro 2000 championship will receive a fully funded Indy NXT drive.

[38] Despite using the same package as the most continental European Formula 4 championships prior 2022, only one national F4 series can be recognized by FIA, thus it is ineligible for the Super License points.

[39] The main reason for the decision was the low number of participating drivers due to the high costs compared to other Formula 4 championships.

The BRDC Formula 4 Championship was an entry-level motorsport series based in the United Kingdom which began in 2013.

Run by the British Racing Drivers' Club and MotorSport Vision, the series used identical cars built by Ralph Firman Racing and engines from Ford, before switching to FIA Formula 4 regulations in 2015, using the Tatuus F4–T014 chassis.
