Formula 1 has issued its first document designed to help fans understand the revolutionary technical changes that will take effect in 2026. The championship promoter aims to “guide” fans in assimilating the initially complex technical terminology, which will become commonplace throughout the 2026 season.
There will be an adaptation period, but as always, everything will soon become familiar. Formula 1 is preparing the ground for the debut of the new generation of cars, arguably the most revolutionary ever given the sheer volume of changes.
Most of the new aspects will be technical, but they will cascade into sporting changes as well, creating a need to make everything as understandable as possible. Liberty Media has outlined the most significant innovations for fans and casual viewers. Together with the FIA and representatives from all eleven teams participating in the next championship, they have defined the terminology needed to quickly grasp the most important changes. Independent surveys involving 50,000 fans were conducted prior to the final release to gather direct feedback.
The document sent by Formula 1 first lists the key technical changes we will see on track next year.
Chassis and aerodynamics
- Smaller and lighter cars: wheelbase reduced by 200 mm (to 3,400 mm), overall width reduced by 100 mm (to 1,900 mm), floor width reduced by 150 mm, and minimum weight decreased by 30 kg (to 768 kg), all designed to make the cars more agile and responsive.
- Reduced aerodynamic load: overall aerodynamic load reduced by approximately 15–30% thanks to the removal of the ground-effect floor tunnels.
- Reduced aerodynamic drag: overall drag reduced by 55% to encourage closer racing on track.
- Active aerodynamics: movable front and rear wings replace the Drag Reduction System (DRS) for high- and low-downforce configurations, providing extra grip and speed where drivers need it most.
- Tyres: 18-inch wheels retained, but front tyres narrower by 25 mm and rear tyres narrower by 30 mm, reducing drag and minimizing weight.
Power unit
- 50/50 power split: transition to a balanced power distribution with 50% from the internal combustion engine (ICE) and 50% electric.
- Simplified hybrid: MGU-H eliminated; MGU-K power significantly increased (from 120 kW to 350 kW) to improve overtaking and straight-line speed.
- Sustainable fuel: cars will run on advanced sustainable fuels without compromising performance.
With this new generation of cars, drivers will have to manage several unprecedented aspects, starting with energy management. They will make the final decisions on usage modes, regeneration, and storage. This explains the need for standardized terminology to identify all the new elements that will be crucial in qualifying and race conditions. Here is a summary of the key new terms:
Overtake Mode
Allows drivers within one second of the car ahead to use extra power to attempt an overtake. It replaces DRS and assists with on-track overtaking, becoming a strategic tool that can be used all at once or spread across a lap.
Boost Mode
This system is activated by the driver to deploy energy from the Energy Recovery System (ERS), usable in attack or defense depending on track position. It provides maximum power from both the engine and battery at the push of a button, regardless of where the car is on the circuit.
Recharge
Drivers can recharge their battery with energy recovered during braking, lifting off the throttle at the end of straights, and even in corners where only part of the power is used.
Active Aero
This refers to the dynamic adjustment of front and rear wing elements in specific high-speed sections, with “Corner” and “Straight” modes. It allows strategic adaptability and maximizes the car’s full power potential by providing increased grip on track.
The off-season buzz grows as this glossary drops—marking the start of a truly groundbreaking chapter. Expect these phrases in every broadcast come Melbourne, defining an era of smarter, closer, and more sustainable Grand Prix action.
