Technical

The Tatuus T-421

Wera Tools F4 British Championship Certified by the FIA uses the Tatuus T-421 chassis, powered by a 1.4-litre, turbocharged Abarth engine.

All cars run on Pirelli control tyres and are performance-equalised by Neil Brown Engineering to ensure fairness across all cars.

Aerodynamics

This second generation car has a larger wheelbase to accommodate the mounting points on the chassis for the Halo-style device. The car also features revised front and rear aerodynamics.

Tyres

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

Engine and Gearbox

The Tatuus T-421 is powered by a 1.4-litre, turbocharged Abarth engine. Engines are equalised by Neil Brown Engineering twice per season and constantly monitored throughout events to ensure parity, putting driver talent front and centre to achieve success.
The gearbox is six-speed sequential with paddle shifts.

Safety

The Halo-style cockpit protection device affords heightened cockpit safety for the car of choice for British Formula 4. This car also benefits from strengthened anti-intrusion panels, and, complemented with onboard in-car signalling and marshalling systems, Britain’s F4 car can lay claim to being the safest of its kind worldwide.
