Active Aero & Overtake Mode - Understanding F1's Fresh Regulatory Language
The 2026 cars are designed to be more compact, agile and eco-conscious than this year.
The world of Formula 1 has revealed the new vocabulary that will be used to reference the advanced features of its revolutionary 2026 regulations.
The sport is embarking on what is arguably the largest technical shift in its illustrious history for the 2026 campaign, featuring fresh chassis and power unit regulations and the required adoption of fully sustainable fuels.
The updated 1.6-litre V6 turbo hybrids, which keep the 1.6-litre V6 configuration, boast a greatly enhanced electrical capacity, necessitating major innovations in the aero packages.
During grand prix events, drivers will carefully oversee battery power – potentially on flying laps – to extract the optimal result.
Extensive fan consultation were undertaken with a wide range of fans, including long-time followers and newcomers, to determine which terms would aid comprehension of the key features of the upcoming rules.
The key objective was to make a series of complex new areas of the racing as easy to grasp 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 favour of descriptive names that succinctly convey the actual function of the technology.
Key Technical Innovations
According to rule-makers that drivers will have increased agency to determine tactics regarding energy deployment, regeneration, and conservation.
The new regulations mandate a range of settings that will be clearly indicated on TV overlays to improve the audience's understanding of the race battle.
- Attack Mode: This replaces the existing Drag Reduction System. It provides a surge of additional ERS power accessible when a car is less than a second the vehicle in front to execute an pass.
- Extra Push Mode: This is a on-demand battery discharge from the energy recovery system that can be deployed for attack or defence. It delivers the pilot full engine and battery energy at the activation of a control.
Both of these strategic tools will have to be used with calculation, as the available electrical charge is strictly limited.
- Active Aero: Both the front and rear wings adjust their angles – spreading on the straights for minimal air resistance and increased velocity, and angling down in the turns for peak grip.
- Energy Harvesting: Cars can harvest energy with regenerative braking, or during coasting at the straight's end or in sections where only partial power is applied.
Car Design Evolution
The vehicles for the new era will be smaller and lighter relative to current models, with a car length reduced by 200mm to 3,400mm, car width reduced by 100mm – down to 1,900mm – and the car weight lowered by 30kg.
Total aerodynamic grip is expected to drop by approximately 15-30%, although constructors will naturally regain performance as they refine their designs.
Air resistance has been slashed by 40%. The vehicles will feature moveable wing elements – both wings will move on the straight sections to cut resistance and boost top speed and click back into place for maximum cornering performance.
Tyres will keep 18-inch wheel rims, but the actual tyres will be reduced in width, by 25 millimetres on the front axle and 30 millimetres on the rear axle.
What's Changing in the Engines?
The revised hybrid units will have an approximate 50-50 split in energy output by the internal combustion engine and the battery and motor, a rise from about 20% electrical in the current formula.
The ERS setup is simplified through the deletion of the complex turbo energy recovery device, the sophisticated and pricey device that generated electricity from the turbo.
Cars will be obliged to compete on fully sustainable fuel, manufactured from organic sources or synthetic industrial processes.
