Overtake Mode & Active Aero - Understanding F1's New Technical Language
The 2026 Formula 1 cars are expected to be lighter, more agile and sustainable relative to present-day cars.
Formula 1 has introduced the official language that will be used to describe the technical complexities of its upcoming 2026 rulebook.
The championship is introducing what is considered the biggest technical shift in its competitive history next season, featuring new chassis and engine rules and the required adoption of 100% sustainable fuels.
The revised engines, which maintain the 1.6-litre V6 turbo hybrid, boast a substantially higher battery power, requiring key advancements in the vehicles' aerodynamic design.
During grand prix events, drivers will strategically manage battery power – including during hot laps – to secure the peak lap time.
Wide-ranging research were carried out with a mix of viewers, including new, casual and core fans, to determine which terminology would aid comprehension of the central aspects of the new regulations.
The key objective was to render a range of advanced technical aspects of the competition as easy to grasp as possible for the widest audience.
Consequently, previous placeholder terms for certain devices – such as "alphabetical mode names" for the moveable wings – have been discarded in favor of straightforward terms that succinctly convey the actual function of the innovation.
Key Technical Innovations
The FIA states that racers will have more power to choose strategies regarding battery management, harvesting, and efficiency.
The new regulations introduce a range of settings that will be clearly indicated on television graphics to enhance the fans' insight of the race battle.
- Attack Mode: This replaces the present overtaking aid. It provides a short boost of battery power accessible when a driver is close behind the leading car to facilitate an overtaking maneuver.
- Boost Mode: This is a driver-operated energy deployment from the energy recovery system that can be utilized during attack or defence. It provides the pilot peak output at the activation of a control.
Both of these key functions will have to be managed carefully, as the total energy is capped.
- Active Aerodynamics: Both the car's wings move automatically – opening on the long straight sections for reduced drag and top speed, and sealing in the bends for maximum downforce.
- Energy Harvesting: The system can replenish their battery with regenerative braking, or during partial power application at the straight's end or in sections where only limited engine output is used.
What's Changing on the Cars?
The 2026 cars will be more compact and lighter than this year, with a wheelbase cut by 200mm to 3,400mm, car width narrowed by 100mm – down to 1,900mm – and the minimum weight decreased by 30kg.
Overall downforce is expected to drop by approximately a significant margin, although squads will undoubtedly recover some as they optimize their packages.
Drag has been reduced by 40%. The cars will employ active aerodynamics – front and rear wings will open on the straight sections to reduce drag and boost top speed and return into place for peak handling.
Wheels will keep the current rim size, but the tyres themselves will be narrower, by a quarter-centimetre on the front and 30mm at the rear.
Power Unit Revolution
The 2026 engines will have an near-equal balance in horsepower generated by the ICE and the ERS, increasing from about 20% electrical in the current formula.
The hybrid system is streamlined through the deletion of the Motor Generator Unit – Heat, the intricate and expensive unit that generated electricity from the turbo.
Cars will be mandated to operate on carbon-neutral fuel, produced using biomass or lab-created processes.
