Overtake Mode & Active Aero - Explaining F1's Updated Regulatory Terminology
The 2026 cars are expected to be lighter, more agile and sustainable compared to current models.
F1 has unveiled the new terminology that will be used to explain the advanced features of its upcoming 2026 regulations.
The sport is implementing what is considered the most significant rules overhaul in its illustrious history for the 2026 campaign, featuring new chassis and engine rules and the compulsory introduction of eco-friendly fuels.
The new power units, which retain the hybrid V6 layout, boast a greatly enhanced energy storage, driving significant developments in the cars' aerodynamics.
During grand prix events, competitors will carefully oversee battery power – including during hot laps – to secure the peak lap time.
Wide-ranging research were carried out with a wide range of fans, including new, casual and core fans, to identify which phrases would make things clearer of the central aspects of the new regulations.
The key objective was to make a set of intricate technical aspects of the sport as accessible as possible for the broadest viewership.
Consequently, initial designations for specific components – such as "modes labelled X and Z" for the moveable wings – have been abandoned in favor of straightforward terms that directly explain the primary purpose of the technology.
Key Technical Innovations
Regulators explain that competitors will have more power to make decisions regarding battery management, harvesting, and efficiency.
The 2026 rules feature a series of modes that will be visually displayed on TV overlays to enhance the audience's understanding of the strategic duel.
- Overtake Mode: This takes over from the current DRS. It provides a short boost of battery power accessible when a driver is close behind the leading car to assist with an pass.
- Power Mode: This is a driver-operated power boost from the energy recovery system that can be deployed for attack or defence. It provides the driver full engine and battery energy at the click of a switch.
Both of these crucial modes will have to be managed carefully, as the total energy is strictly limited.
- Active Aero: Both the car's wings move automatically – spreading on the long straight sections for low aerodynamic resistance and increased velocity, and closing in the turns for peak grip.
- Recharge: The system can recharge the energy store with energy harvested under braking, or during throttle lift at the end of straights or in corners where only limited engine output is required.
What's Changing on the Cars?
The next-generation machines will be reduced in size and weight than this year, with a distance between axles reduced by 200mm to 3,400mm, width narrowed by 100mm – down to 1,900mm – and the car weight reduced by 30kg.
Overall downforce is projected to decrease by approximately fifteen to thirty percent, although teams will naturally regain performance as they develop their cars.
Aerodynamic drag has been reduced by 40%. The vehicles will employ adjustable aero systems – front and rear wings will move on the straight sections to improve speed and enhance velocity and click back into place for maximum cornering performance.
Tyres will retain the current rim size, but the rubber compounds will be reduced in width, by 25mm at the front and three centimetres on the rear.
2026 Engine Regulations
The revised hybrid units will have an near-equal balance in horsepower generated by the ICE and the battery and motor, a rise from about 20% electrical in the current formula.
The ERS setup is simplified through the elimination of the Motor Generator Unit – Heat, the complicated and costly device that harvested power from the turbocharger.
All vehicles will be mandated to operate on 100% sustainable fuel, produced using organic sources or synthetic industrial processes.
