Overtake Mode & Active Aero - Explaining F1's New Technical Terminology
The 2026 cars are designed to be more compact, agile and eco-conscious than this year.
F1 has revealed the simplified language that will be used to reference the technical complexities of its revolutionary 2026 technical rules.
The sport is implementing what is potentially the largest technical shift in its competitive history next season, featuring revised car and engine specifications and the required adoption of fully sustainable fuels.
The revised engines, which maintain the hybrid V6 layout, boast a substantially higher electrical capacity, necessitating key advancements in the cars' aerodynamics.
During grand prix events, drivers will tactically deploy ERS energy – including during hot laps – to achieve the optimal result.
Broad surveys were carried out with a mix of viewers, including long-time followers and newcomers, to identify which terminology would improve understanding of the key features of the new regulations.
The primary aim was to present a set of intricate features of the competition as accessible as possible for the broadest viewership.
Consequently, previous placeholder terms for certain devices – such as "alphabetical mode names" for the adjustable aero – have been abandoned in favour of descriptive names that clearly indicate the real-world effect of the innovation.
Exploring the New Tech
According to rule-makers that racers will have more power to determine tactics regarding energy deployment, regeneration, and saving energy.
The 2026 rules feature a set of functions that will be clearly indicated on TV overlays to enhance the fans' insight of the on-track action.
- Attack Mode: This supersedes the present overtaking aid. It provides a short boost of battery power available when a driver is within one second the car ahead to execute an pass.
- Extra Push Mode: This is a manual battery discharge from the ERS that can be deployed for overtaking or defending. It grants the pilot peak output at the activation of a control.
Both of these key functions will have to be managed carefully, as the total energy is strictly limited.
- Adjustable Aero: Both the car's wings adjust their angles – opening on the straights for reduced drag and higher speed, and closing in the bends for maximum downforce.
- Battery Recharge: Drivers can recharge the energy store with power recovered from braking, or during partial power application at the end of straights or in corners where only limited engine output is applied.
Car Design Evolution
The vehicles for the new era will be more compact and lighter compared to the 2025 spec, with a wheelbase shortened by 200mm to 3,400mm, width reduced by 100mm – down to 1,900mm – and the minimum weight lowered by 30kg.
Total aerodynamic grip is expected to drop by approximately a significant margin, although squads will naturally regain performance as they develop their cars.
Aerodynamic drag has been cut by 40%. The vehicles will utilize moveable wing elements – front and rear wings will adjust on the straights to improve speed and enhance velocity and return into place for optimal grip in corners.
Pirelli tyres will continue to use the current rim size, but the actual tyres will be slimmer, by a quarter-centimetre on the front and 30mm at the rear.
2026 Engine Regulations
The revised hybrid units will have an near-equal balance in horsepower generated by the internal combustion engine and the electrical system, up from about 20% battery contribution this year.
The hybrid system is made less complex through the deletion of the Motor Generator Unit – Heat, the complicated and costly component that recovered energy from the exhaust turbo.
All vehicles will be required to run on 100% sustainable fuel, created from biomass or synthetic production methods.
