The British F4 Championship uses the Tatuus T-421 chassis, powered by a 1.4 litre, turbocharged Abarth engine and was introduced as the latest generation of F4 car in 2022.

All cars run Pirelli control tyres and are performance-equalised by Neil Brown Engineering to ensure fairness across all cars, thus putting driver talent front and centre.

The Halo-style cockpit protection device affords heightened cockpit safety and the car also benefits from strengthened anti-intrusion panels. Complemented with on-board in-car signalling and marshalling systems, the British F4 car can lay claim to being the safest of its kind worldwide.

British F4 uses Pirelli P Zero racing slick tyres in line with the rest of the single-seater pathway, ensuring a relevant education for drivers before they graduate to other Pirelli-shod categories further up the ladder to Formula 1.
