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.

Contents

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. 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 [2] 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.

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 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.

In practice, costs for competitors considerably exceed this goal; the cost of participating in the 2022 French Formula 4 series (including all equipment) was € 118,000, excluding tax. [3] Costs in other F4 championships can be considerably higher, with one estimate of the costs of a realistic attempt at the now-defunct German F4 series championship in excess of € 350,000. [4]

Homologated chassis manufacturers

To become eligible for FIA Formula 4, the chassis must meet the FIA homologation requirements respecting technical and commercial regulations. Four chassis manufacturers have been approved by the FIA: [5] Tatuus, Mygale, Dome and Ligier.

To become an eligible FIA Formula 4 engine, the engine must meet the homologation requirements. 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. [6] According to the FIA Formula 4 technical regulations only four cylinder engines are allowed. Both normally aspirated and turbocharged engines are permitted, with an absolute maximum power output of 140kW. The engine displacement is unlimited. [7] Currently seven engines are homologated for use in the FIA Formula 4. [5]

Performance

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.

Compared to road-legal supercars, Formula 4 cars are less accelerative and have a much lower top speed of approximately 240 km/h; most modern supercars are capable of in excess of 300 km/h. The F4 cars have far superior braking and cornering capabilities, particularly in high-speed corners where the aerodynamic downforce of the Formula 4 cars has the most effect. [9]

According to official information from the F1 Academy, the Tatuus race car (virtually identical to the one used in some F4 series) has a peak lateral cornering acceleration of about 2.0g, [10] far in excess of a typical (non-sporting) road car which peaks at less than 1g, but considerably less than Formula 3 cars (which peak around 2.5g).

To give some idea of the gap between F4 and F1 performance levels, the fastest qualifying lap for a 2023 F4 round at the Silverstone GP circuit was 2:01.651; [11] the pole lap in the 2024 British Grand Prix in an F1 car was 1:25.819.

However, F4 cars still lap considerably faster than most production-derived racing categories. The F4 pole time is about 2 seconds faster than the Porsche Carrera Cup lap record and about 10 seconds faster than the TCR Touring Car lap record.

Active FIA-sanctioned championships

FIA Motorsport Games

A Formula 4 race forms part of the FIA Motorsport Games, a biennial event featuring a variety of motorsport disciplines including karting, drifting, rallying, and esports as well as circuit racing [12] .

FIA-sanctioned national/regional championships

These championships are held to Formula 4 regulations and approved by the FIA as the national Formula 4 series. [13] Drivers participating in these series can receive FIA Super Licence points, which are required to drive in Formula One. For a series to be eligible for Super Licence points, a season must be held over at least five events at a minimum of three circuits, according to FIA Appendix L. [14] While titled national series, some series are contested at tracks in multiple countries.

JAF Japan Formula 4

Japan Formula 4 is a formula racing series in Japan. The series was founded in 1993 by the Japan Automobile Federation as a class between the FJ1600 series and the All-Japan Formula Three Championship. Japanese Formula 4 is an open formula, where competitors can choose the chassis and engine manufacturers.

Canada CASC Formula 4/F4

This is based on a non-FIA formulae, instead using 750cc motorcycle engines as power plants. Chassis are typically locally produced such as Xpit and Gamma and cars are fueled by methanol. Popular in the CASC Ontario region at a club level only since 1974.

FIA Central European Zone Championship / Drexler Formel 4 Cup

Although it's an FIA zone championship, the single-seater races in the FIA CEZ Championship have a division for Formula 4 cars, but they are not part of the FIA ladder. 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. [35]

USF Juniors

The USF Juniors is an F4 series for 14 and 15-year old drivers transitioning from karts. It is organised by Andersen Promotions, the promoter of the USF Pro Championships USF2000 and Pro 2000, with sanctioning from the United States Auto Club.

The series began in 2022 with the Ligier JS F4 currently used by United States Formula 4 with the homologated Honda engine provided by their series' spec engine builder (which is different from the US F4 championship, where the engines come from Honda itself). It then switched to the Tatuus USF-22, a variant of the Tatuus F4 chassis with the Mazda MZR engine starting in 2023. The series does not use the Sports Car Club of America series' Hankook tyres. Originally aligned with Goodyear Tire and Rubber Company's Cooper Tires imprint in 2022 and 2023, the USAC series will have tyres provided by Continental AG starting in 2024. This series is not part of the FIA ladder, but instead the USF Pro Championships ladder. This includes media training and the winner earning a fully funded drive in the next season's USF2000 championship, which all winners of lower series receives. The winner of the USF Pro 2000 championship will receive a fully funded Indy NXT drive. [36]

GB4 Championship

Organized by MSV in the collaboration with British Racing Drivers' Club. The GB4 Championship races alongside GB3 Championship during the British GT Championship events and acts as its feeder series and requires lower financial contribution than F4 British Championship certified by FIA. It uses Tatuus F4 T-014 chassis, Abarth 414TF 1.4L engine and Pirelli tires. [37] 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.

Fórmula 4 Chile

Organised by Campeonato Nacional de Carreras Federado, the series uses the Tatuus FA010 chassis from Formula Abarth, one of the predecessors of the Formula 4 car.

Former Formula 4 championships

ADAC Formula 4 Championship

The ADAC Formula 4 Championship was held from 2015 to 2022. On 3 December 2022, ADAC announced that ADAC Formula 4 would not be organized for the 2023 season, with the focus on placing the German junior drivers in the French F4 Championship instead. [38] The main reason for the decision was the low number of participating drivers due to the high costs compared to other Formula 4 championships. [39]

F4 Argentina Championship

Common usage of "formula racing" encompasses other single-seater series, including the IndyCar Series and the Super Formula Championship.

The German Formula Three Championship was the national Formula Three championship of Germany, and the former West Germany, from 1950 to 2002, then as Formel 3 until 2014. In 2003, the series had merged with the French Formula Three Championship to form the Formula 3 Euro Series. The lower-level series, the ATS Formel 3 Cup, subsequently operated in Germany, but it folded after the end of the 2014 season. Since the late 1980s, the list of German F3 champions has included many notable drivers, including Formula One World Champion Michael Schumacher and nine-time Le Mans winner Tom Kristensen.
