The Car
The Tatuus F4-T014 is one of the most successful single-seater cars produced in recent decades, with well over 200 examples manufactured since 2014 and driven by current F1 stars Lando Norris and Lance Stroll amongst others to launch their careers.
The car runs exactly as it did in Italian, ADAC and Spanish F4, meaning this is one of the most proven, reliable and equitable single-seaters available.
GB4’s F4-T014 utilises a carbon fibre Tatuus chassis and is powered by a 1.4-litre turbocharged Autotecnica Motori engine producing 160bhp. Engine parity is optimised by existing GB3 partner Mountune. The chassis is FIA-homologated, allowing drivers as young as 15 to race them.
It features a six-speed sequential gearbox with paddle shift provided by Sadev, with Magneti Marelli electronics.
The F4-T014 is not only a superb race car, but an enormously safe one too, ideal for drivers from as young as 15 years of age to make their first steps on the single-seater racing ladder – no serious injuries have been recorded in more than 400 races and 140,000 racing laps. It features FIA-approved front and rear crash structures, wheel tethers, removable lateral head protection, roll hoop, a six-point safety harness, cockpit safety cell, carbon fibre extractable seat, and anti-intrusion panels.
Adjustable front and rear wings ensure set-up variation at all circuits, while Pirelli extend their support from GB3 to GB4, providing dry and wet tyres to the championship.
The braking system is provided by Brembo and features 2-piston calipers and ventilated discs.
Twin wishbone suspension with adjustable camber and toe on the front, and adjustable camber, toe, roll centre and anti-squat at the rear provide added scope for set-up changes. Oram provide adjustable bump and rebound dampers.
Cars are available from around £25,000 complete with engine, whilst GB3 teams can use 80% of the same spares whilst maintaining and preparing cars from the two championships. Cost minimisation and controls is implemented by series organiser MSV.
