Overtake Mode & Active Aero - Explaining F1's New Technical Jargon
The vehicles for the 2026 season are expected to be lighter, more agile and sustainable relative to present-day cars.
Formula 1 has revealed the new terminology that will be used to explain the intricate details of its revolutionary 2026 rulebook.
The championship is embarking on what is potentially the most significant regulation change in its competitive history for the 2026 campaign, featuring new chassis and engine rules and the required adoption of fully sustainable fuels.
The new power units, which retain the 1.6-litre V6 configuration, boast a greatly enhanced battery power, requiring significant developments in the vehicles' aerodynamic design.
Throughout races, competitors will carefully oversee electrical energy – potentially on qualifying laps – to extract the best lap time.
Wide-ranging research were carried out with a diverse audience, including dedicated enthusiasts and casual observers, to identify which phrases would aid comprehension of the central aspects of the 2026 changes.
The key objective was to render a set of intricate technical aspects of the competition as straightforward as possible for the widest audience.
Consequently, older technical labels for some systems – such as "modes labelled X and Z" for the active aerodynamics – have been phased out in favour of descriptive names that clearly indicate the real-world effect of the technology.
Exploring the New Tech
The FIA states that drivers will have more power to make decisions regarding energy deployment, energy recovery, and saving energy.
The 2026 rules introduce a set of functions that will be clearly indicated on television graphics to aid the audience's understanding of the on-track action.
- Overtake Mode: This takes over from the present overtaking aid. It provides a surge of additional ERS power deployable when a competitor is less than a second the leading car to facilitate an overtaking maneuver.
- Extra Push Mode: This is a on-demand energy deployment from the ERS that can be used in offensive or defensive moves. It delivers the driver full engine and battery energy at the click of a switch.
Both of these crucial modes will have to be used with calculation, as the available electrical charge is strictly limited.
- Active Aerodynamics: Both the car's wings adjust their angles – spreading on the high-speed sections for low aerodynamic resistance and higher speed, and closing in the bends for peak grip.
- Battery Recharge: Drivers can replenish their battery with power recovered from braking, or during coasting at the conclusion of a straight or in certain corners where only reduced throttle is used.
Car Design Evolution
The 2026 cars will be more compact and lighter relative to current models, with a wheelbase cut by 200mm to 3,400mm, overall width cut by 100mm – down to 1,900mm – and the minimum weight lowered by 30kg.
Total aerodynamic grip is projected to decrease by approximately 15-30%, although teams will inevitably claw this back as they optimize their packages.
Aerodynamic drag has been slashed by 40%. The vehicles will feature adjustable aero systems – front and rear wings will move on the straights to reduce drag and increase straightline speed and revert into place for maximum cornering performance.
Pirelli tyres will continue to use the current rim size, but the actual tyres will be reduced in width, by a quarter-centimetre on the front 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 power produced by the internal combustion engine and the ERS, a rise from about 20% battery contribution in the current formula.
The ERS setup is streamlined through the removal of the complex turbo energy recovery device, the intricate and expensive device that recovered energy from the exhaust turbo.
Cars will be obliged to compete on fully sustainable fuel, produced using organic sources or synthetic production methods.
