Active Aero & Overtake Mode - Understanding F1's Fresh Technical Jargon

Formula 1 has unveiled the official language that will be used to explain the advanced features of its revolutionary 2026 regulations.

The championship is implementing what is considered the biggest rules overhaul in its illustrious history for the 2026 campaign, featuring fresh chassis and power unit regulations and the required adoption of eco-friendly fuels.

The new power units, which keep the hybrid V6 layout, boast a significantly increased battery power, necessitating key advancements in the aero packages.

Throughout races, drivers will strategically manage electrical energy – sometimes even flying laps – to achieve the best lap time.

Extensive fan consultation were undertaken with a mix of viewers, including long-time followers and newcomers, to identify which terms would aid comprehension of the key features of the upcoming rules.

The primary aim was to make a set of intricate new areas of the racing as easy to grasp as possible for the widest audience.

Consequently, initial designations for specific components – such as "alphabetical mode names" for the adjustable aero – have been discarded in favor of descriptive names that succinctly convey the primary purpose of the system.

What's the New Technology?

The FIA states that drivers will have increased agency to determine tactics regarding power usage, harvesting, and conservation.

The 2026 rules introduce a series of modes that will be shown on TV overlays to aid the audience's understanding of the on-track action.

• Attack Mode: This replaces the present overtaking aid. It provides a surge of additional ERS power accessible when a car is less than a second the vehicle in front to execute an overtaking maneuver.
• Extra Push Mode: This is a manual energy deployment from the hybrid system that can be deployed for offensive or defensive moves. It delivers the pilot maximum power at the click of a switch.

Both of these strategic tools will have to be deployed strategically, as the overall battery capacity is capped.

• Adjustable Aero: Both the front and rear wings move automatically – opening on the straights for minimal air resistance and increased velocity, and angling down in the turns for peak grip.
• Energy Harvesting: The system can replenish their battery with regenerative braking, or during throttle lift at the straight's end or in corners where only partial power is required.

What's Changing on the Cars?

The 2026 cars will be more compact and lighter relative to current models, with a distance between axles shortened by 200mm to 3,400mm, width cut by 100mm – down to 1,900mm – and the car weight decreased by 30kg.

Overall downforce is projected to decrease by approximately fifteen to thirty percent, although squads will inevitably claw this back as they refine their designs.

Drag has been cut by 40%. The vehicles will utilize active aerodynamics – front and rear wings will open on the straights to cut resistance and increase straightline speed and return into place for maximum cornering performance.

Tyres will keep 18-inch wheel rims, but the rubber compounds will be reduced in width, by 25mm at the front and 30 millimetres on the rear axle.

Power Unit Revolution

The revised hybrid units will have an roughly half-and-half distribution in power produced by the internal combustion engine and the battery and motor, increasing from about 20% battery contribution this year.

The hybrid system is simplified through the removal of the MGU-H, the sophisticated and pricey component that harvested power from the turbo.

Cars will be obliged to compete on fully sustainable fuel, produced using organic sources or lab-created processes.
