Overtake Mode & Active Aero - Decoding F1's Fresh Regulatory Language
The vehicles for the 2026 season are designed to be more compact, agile and eco-conscious relative to present-day cars.
Formula 1 has unveiled the new terminology that will be used to reference the intricate details of its revolutionary 2026 technical rules.
The sport is embarking on what is arguably the biggest rules overhaul in its illustrious history next season, featuring revised car and engine specifications and the required adoption of 100% sustainable fuels.
The updated 1.6-litre V6 turbo hybrids, which retain the hybrid V6 layout, boast a substantially higher battery power, requiring significant developments in the cars' aerodynamics.
During grand prix events, competitors will tactically deploy electrical energy – potentially on qualifying laps – to extract the best performance.
Broad surveys were conducted with a mix of viewers, including long-time followers and newcomers, to identify which terms would make things clearer of the key features of the 2026 changes.
The key objective was to present a series of complex new areas of the racing as accessible as possible for the widest audience.
Consequently, initial designations for certain devices – such as "x-mode and z-mode" for the adjustable aero – have been phased out in favour of intuitive labels that succinctly convey the actual function of the innovation.
Exploring the New Tech
According to rule-makers that competitors will have more power to choose strategies regarding energy deployment, energy recovery, and conservation.
The new regulations mandate a range of settings that will be visually displayed on broadcast screens to aid the audience's understanding of the race battle.
- Passing Mode: This supersedes the existing Drag Reduction System. It provides a burst of extra electrical energy deployable when a competitor is less than a second the car ahead to execute an overtake.
- Extra Push Mode: This is a on-demand energy deployment from the hybrid system that can be utilized during offensive or defensive moves. It grants the driver peak output at the click of a switch.
Both of these crucial modes will have to be deployed strategically, as the available electrical charge is restricted.
- Active Aerodynamics: Both the front and rear wings adjust their angles – spreading on the straights for minimal air resistance and increased velocity, and closing in the corners for maximum downforce.
- Recharge: Cars can harvest energy with energy harvested under braking, or during throttle lift at the conclusion of a straight or in certain corners where only reduced throttle is required.
What's Changing on the Cars?
The 2026 cars will be more compact and lighter relative to current models, with a car length cut by 200mm to 3,400mm, car width cut by 100mm – down to 1,900mm – and the minimum weight reduced by 30kg.
Overall downforce is projected to decrease by approximately a significant margin, although teams will inevitably claw this back as they develop their cars.
Aerodynamic drag has been slashed by 40%. The cars will feature moveable wing elements – both wings will move on the straights to reduce drag and enhance velocity and return into place for peak handling.
Tyres will keep 18-inch rims, but the tyres themselves will be narrower, by 25 millimetres on the front axle and three centimetres on the rear.
Power Unit Revolution
The new power units will have an near-equal balance in power produced by the internal combustion engine and the ERS, up from about 20% battery contribution under present rules.
The ERS setup is made less complex through the removal of the complex turbo energy recovery device, the complicated and costly unit that recovered energy from the turbocharger.
Every car on the grid will be mandated to operate on fully sustainable fuel, manufactured from biomass or synthetic production methods.
