Overtake Mode & Active Aero - Decoding F1's Updated Technical Jargon

The world of Formula 1 has introduced the official vocabulary that will be used to reference the intricate details of its new 2026 technical rules.

The racing series is embarking on what is potentially the largest technical shift in its illustrious history for the 2026 campaign, featuring revised car and engine specifications and the required adoption of 100% sustainable fuels.

The updated 1.6-litre V6 turbo hybrids, which keep the 1.6-litre V6 turbo hybrid, boast a substantially higher battery power, requiring significant developments in the vehicles' aerodynamic design.

During grand prix events, drivers will strategically manage ERS energy – sometimes even flying laps – to secure the peak result.

Broad surveys were conducted with a wide range of fans, including dedicated enthusiasts and casual observers, to determine which phrases would aid comprehension of the main elements of the new regulations.

The primary aim was to present a series of complex new areas of the racing as straightforward as possible for the widest audience.

Consequently, initial designations for certain devices – such as "modes labelled X and Z" for the adjustable aero – have been discarded in favor of descriptive names that clearly indicate the real-world effect of the innovation.

What's the New Technology?

Regulators explain that racers will have greater control to choose strategies regarding battery management, harvesting, and efficiency.

The upcoming changes introduce a set of functions that will be clearly indicated on broadcast screens to enhance the fans' insight of the strategic duel.

• Attack Mode: This supersedes the present overtaking aid. It provides a burst of extra electrical energy accessible when a competitor is close behind the leading car to execute an overtake.
• Boost Mode: This is a manual battery discharge from the energy recovery system that can be deployed for overtaking or defending. It delivers the pilot maximum power at the push of a button.

Both of these key functions will have to be managed carefully, as the overall battery capacity is capped.

• Active Aerodynamics: Both the nose and rear wings move automatically – opening on the high-speed sections for minimal air resistance and increased velocity, and sealing in the turns for maximum downforce.
• Energy Harvesting: The system can harvest energy with energy harvested under braking, or during partial power application at the straight's end or in certain corners where only reduced throttle is used.

2026 Car Specifications

The next-generation machines will be reduced in size and weight relative to current models, with a car length shortened by 200mm to 3,400mm, width cut by 100mm – down to 1,900mm – and the car weight reduced by 30kg.

Overall downforce is anticipated to be reduced by approximately 15-30%, although squads will naturally regain performance as they refine their designs.

Drag has been cut by 40%. The cars will utilize active aerodynamics – both wings will move on the straight sections to improve speed and increase straightline speed and return into place for optimal grip in corners.

Wheels will continue to use 18-inch rims, but the rubber compounds will be reduced in width, by 25 millimetres on the front axle and 30mm at the rear.

What's Changing in the Engines?

The new power units will have an near-equal balance in power produced by the ICE and the electrical system, a rise from about 20% electrical under present rules.

The hybrid system is streamlined through the deletion of the Motor Generator Unit – Heat, the intricate and expensive component that harvested power from the turbocharger.

Cars will be obliged to compete on carbon-neutral fuel, created from plant-based materials or synthetic production methods.
