GB3 Championship: The Premier Path for Single-Seater Racing in the UK
The GB3 Championship stands as the United Kingdom's premier single-seater motorsport category. Designed as a critical stepping stone for aspiring racing drivers, the series provides a professional environment for those transitioning from karting, the GB4 Championship, or FIA Formula 4 championships.
As a spec series, GB3 ensures a level playing field by requiring all competitors to use identical cars, engines, and tyres. This structure shifts the focus from technical spending to driver skill and team strategy. While not officially branded as such, the car specifications for the 2025 season align with Formula Regional standards, maintaining a performance level consistent with international junior formulas.

Evolution and History
The championship has undergone several identity shifts to reflect its growing pace and position within the motorsport hierarchy. It began as a Formula 4 series operated by the 750 Motor Club before being awarded to MotorSport Vision (MSV) in 2013. Under the name BRDC Formula 4 Championship, the series saw early success from drivers like Jake Hughes, the inaugural 2013 champion.
The series gained significant prestige by producing future stars. George Russell claimed the title in 2014, and Will Palmer dominated the 2015 season with 12 victories. In March 2016, the series was rebranded as the BRDC British Formula 3 Championship to fill the void left by the folding of the British Formula 3 Championship and to reflect the increased speed of the new machinery.
In August 2021, the series was renamed the GB3 Championship. This change followed an FIA decision to restrict the "F3" designation exclusively to the FIA Formula 3 Championship. Zak O'Sullivan became the first champion under the GB3 banner.
Technical Advancements
The machinery has evolved rapidly to improve safety and performance. In 2022, the series introduced the Tatuus MSV-022, which featured the addition of the halo safety device and delivered lap times two to three seconds faster than the previous car.
Looking forward, the 2025 season will see the debut of the Tatuus MSV GB3-025. This new model introduces F1-inspired aerodynamics, a Drag Reduction System (DRS), and a new Mountune 2.0L engine capable of generating 280bhp.
Competition and Scoring
The GB3 Championship employs a sophisticated points system to reward consistency and overtaking. Since 2014, the series has utilized a tiered scoring system for its race weekends.
| Position | Races 1 & 3 Points | Reverse Grid Race (Race 2) Points |
|---|---|---|
| 1st | 35 | 25 |
| 2nd | 29 | 22 |
| 3rd | 24 | 20 |
| 4th | 21 | 18 |
| 5th | 19 | 16 |
| 6th | 17 | 15 |
| 7th | 15 | 14 |
A unique aspect of the championship is the reverse grid for the second race. In these events, drivers can earn an additional point for every position they gain relative to their starting position, incentivizing aggressive and skillful overtaking.

The Tatuus MSV GB3-025 will feature F1-inspired aerodynamics, a Drag Reduction System (DRS), and a Mountune 2.0L engine producing 280bhp.
