FIA Formula 4, also called FIA F4, is an open-wheel racing car category intended for junior drivers.
There is no global championship, but rather individual nations or regions can host their own championships in compliance with a universal set of rules and specifications.
The category was created by the Fédération Internationale de l’Automobile (FIA)—the International sanctioning and administrative body for motorsport—as an entry-level category for young drivers, bridging the gap between karting and Formula 3. The series is a part of the FIA Global Pathway. Former Formula One driver Gerhard Berger was appointed as the FIA Single-Seater Commission president to oversee the creation of the category as a response to declining interest in national Formula 3 championships due to rising costs and alternate pathways to Formula One such as the then Formula Renault and GP2 and GP3 Series, which had seen several national Formula 3 championships discontinued. In the place of the expensive categories, a number of separate categories running under the Formula 4 name had been created, for example, the British based the former BRDC Formula 4. There was no commonality between the cars from country to country. The FIA-endorsed category was formally created in March 2013, when it was approved by the World Motor Sport Council.
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. Each championship uses a single make of engine, with the regulations mandating a 1,600 cc (1.6 L) capacity and capping the maximum power output at 160 bhp (119.3 kW), higher than Formula Ford and lower than Formula Renault. The engines are equalized 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.
