Active Aero & Overtake Mode - Explaining F1's Fresh Technical Language

F1 has introduced the simplified vocabulary that will be used to reference the advanced features of its revolutionary 2026 technical rules.

The championship is embarking on what is arguably the biggest rules overhaul in its long history starting in 2026, featuring revised car and engine specifications and the required adoption of fully sustainable fuels.

The new power units, which retain the 1.6-litre V6 configuration, boast a significantly increased battery power, necessitating significant developments in the vehicles' aerodynamic design.

Over a race distance, competitors will tactically deploy battery power – including during qualifying laps – to secure the peak result.

Extensive fan consultation were undertaken with a diverse audience, including long-time followers and newcomers, to understand which terminology would make things clearer of the key features of the new regulations.

The stated goal was to make a range of advanced features of the sport as easy to grasp as possible for the widest audience.

Consequently, previous placeholder terms for specific components – such as "alphabetical mode names" for the adjustable aero – have been abandoned in favour of descriptive names that directly explain the actual function of the technology.

What's the New Technology?

Regulators explain that racers will have more power to make decisions regarding power usage, energy recovery, and conservation.

The new regulations introduce a range of settings that will be clearly indicated on TV overlays to improve the fans' insight of the on-track action.

• Passing Mode: This takes over from the current DRS. It provides a burst of extra electrical energy accessible when a competitor is close behind the vehicle in front to execute an overtaking maneuver.
• Boost Mode: This is a driver-operated power boost from the energy recovery system that can be utilized during overtaking or defending. It delivers the driver peak output at the click of a switch.

Both of these strategic tools will have to be used with calculation, as the total energy is capped.

• Active Aerodynamics: Both the nose and rear wings move automatically – flattening on the high-speed sections for minimal air resistance and increased velocity, and sealing in the corners for peak grip.
• Battery Recharge: Drivers can replenish their battery with power recovered from braking, or during coasting at the straight's end or in sections where only limited engine output is used.

Car Design Evolution

The 2026 cars will be reduced in size and weight than this year, with a car length cut by 200mm to 3,400mm, width reduced by 100mm – down to 1,900mm – and the car weight decreased by 30kg.

Overall downforce is projected to decrease by approximately a significant margin, although teams will inevitably claw this back as they optimize their packages.

Drag has been reduced by 40%. The vehicles will employ active aerodynamics – both wings will adjust on the straights to improve speed and enhance velocity and return into place for maximum cornering performance.

Pirelli tyres will continue to use 18-inch rims, but the tyres themselves will be narrower, by 25 millimetres on the front axle and 30 millimetres on the rear axle.

2026 Engine Regulations

The revised hybrid units will have an roughly half-and-half distribution in energy output by the internal combustion engine and the battery and motor, a rise from about one-fifth electric power in the current formula.

The energy recovery system is streamlined through the deletion of the Motor Generator Unit – Heat, the intricate and expensive unit that generated electricity from the turbocharger.

Cars will be obliged to compete on fully sustainable fuel, created from biomass or synthetic industrial processes.
