GB3 Championship
Operated by MSV, the GB3 Championship is the UK’s premier single seater racing category, and provides the perfect bridge for drivers between FIA Formula 4 and international competition.
Comprised of 24 races across eight events, the series takes in a number of the UK’s premier venues and makes overseas trips to Spa-Francorchamps and Zandvoort. Drivers race in identical Tatuus MSV-022 machinery, providing a level playing field for the next generation to demonstrate their talents.

Series information
The GB3 Championship utilises the superb new Tatuus MSV GB3-025 car which was introduced into the series for the 2025 season and beyond. This latest single-seater from the renowned Italian constructor builds on the previous car’s great reputation, and elevates GB3 as the compelling choice of series for drivers of FIA F4 level to develop and prove their talent on their path to FIA F3, F2 and ultimately F1.
The new car is the result of a tenth season of collaboration between MSV and Tatuus, with a completely revised chassis and F1-inspired aerodynamics. The package also includes DRS for the first time, along with industry leading safety standards and a new Mountune engine producing 280bhp.
Class-leading aerodynamics
The Tatuus designers have developed the most advanced aerodynamics package ever at this level, which is modelled to add 35% more downforce at the same drag level compared to the previous GB3 car – a radical increase in efficiency.
The new aerodynamic package, including front wing and endplate assembly, powerful underbody aerodynamics, and CFD optimised aero surfaces and rim fairings, draws inspiration from current F1 machinery and has been designed to work in harmony with the bespoke adjustable DRS rear wing, offering young drivers greater ability to develop their race craft and perfect preparation for competition on the global stage.
Reinforcing GB3’s growing stature as a key step on the ladder to F1, key new features include a titanium halo, for greater strength and much reduced weight – and at a critical, high location.
Further aerodynamic improvements include a CFD optimised cooling package for the car as a whole, including the brakes and gearbox oil, whilst an improved brake system is also a feature.
New technical package features tyre size increase and upgraded engine
GB3 continues its association with official F1 tyre supplier Pirelli and wider tyres are a key feature of the new car. Front tyres have been increased from eight to 10 inches in width with the rear tyres sizing up from 10 inches to 12.
The combination of far more efficient aerodynamics with much greater downforce, with the increase in power from the new normally aspirated two-litre, four-cylinder Mountune engine, means that the Tatuus MSV GB3-025 is considerably quicker per lap than the previous model.
The 2025 engine retains the DNA of the previous Mountune-prepared unit but with power increased by 30bhp. Extensive modifications have been applied to the cylinder head and inlet manifold to raise power output, and a re-engineered exhaust system layout increases mid-range performance. A fully stressed sump and totally redesigned cam cover makes this the stiffest-ever for engine mounting and torsional rigidity. Extra sensors to improve engine control and monitoring have also been added to complement serviceability improvements for engine operation.
The FT3 fuel cell has been increased to 70 litres in capacity and is compatible with the latest fully sustainable fuels. Revisions have also been made to the Sadev six speed gearbox, which is lighter. A refined electronic gearshift system is activated by a new bespoke steering wheel.
Tech Specs
MotorSport Vision (MSV) has revealed the new Tatuus MSV GB3-025 car which will be raced in its GB3 Championship from the 2025 season and beyond. This latest single-seater from the renowned Italian constructor is aimed at building on the existing car’s great reputation and elevate GB3 to become the most compelling choice of series for drivers of FIA F4 level to develop and prove their talent on their path to FIA F3, F2 and ultimately F1.
The new car is the result of a tenth season of collaboration between MSV and Tatuus, with a completely revised chassis and F1-inspired aerodynamics.

New technical package features tyre size increase and upgraded engine
GB3 will continue its association with official F1 tyre supplier Pirelli with the introduction of wider tyres for the new generation car. Front tyres have been increased from eight to 10 inches in width with the rear tyres sizing up from 10 inches to 12.
The combination of far more efficient aerodynamics with much greater downforce, with the increase in power from the new normally aspirated two-litre, four-cylinder Mountune engine, means that the Tatuus MSV GB3-025 will be considerably quicker per lap than the current model. The weight of the new car is expected to be approximately 560kg minus fuel and driver.
The 2025 engine will retain the DNA of the current Mountune-prepared unit but with power increased by 30bhp. Extensive modifications will be applied to the cylinder head and inlet manifold to raise power output, and a re-engineered exhaust system layout will increase mid-range performance.
