🔗 Share this article Overtake Mode & Active Aero - Decoding F1's New Technical Jargon The 2026 Formula 1 cars are expected to be lighter, more agile and sustainable relative to present-day cars. The world of Formula 1 has introduced the new vocabulary that will be used to explain the technical complexities of its new 2026 regulations. The sport is implementing what is potentially the largest rules overhaul in its competitive history for the 2026 campaign, featuring new chassis and engine rules and the compulsory introduction of eco-friendly fuels. The new power units, which maintain the 1.6-litre V6 configuration, boast a significantly increased electrical capacity, necessitating significant developments in the vehicles' aerodynamic design. Over a race distance, pilots will tactically deploy electrical energy – sometimes even flying laps – to achieve the peak result. Extensive fan consultation were undertaken with a wide range of fans, including dedicated enthusiasts and casual observers, to understand which phrases would aid comprehension of the key features of the 2026 changes. The primary aim was to render a range of advanced features of the competition as straightforward as possible for the global fanbase. Consequently, older technical labels for certain devices – such as "alphabetical mode names" for the active aerodynamics – have been discarded in favor of descriptive names that directly explain the primary purpose of the technology. Key Technical Innovations The FIA states that competitors will have greater control to make decisions regarding energy deployment, regeneration, and saving energy. The 2026 rules introduce a range of settings that will be visually displayed on TV overlays to improve the audience's understanding of the on-track action. Passing Mode: This replaces the present overtaking aid. It provides a burst of extra electrical energy deployable when a competitor is close behind the car ahead to assist with an overtaking maneuver. Extra Push Mode: This is a on-demand energy deployment from the hybrid system that can be used in overtaking or defending. It delivers the pilot full engine and battery energy at the click of a switch. Both of these crucial modes will have to be managed carefully, as the available electrical charge is restricted. Active Aero: Both the car's wings change configuration – opening on the straights for minimal air resistance and higher speed, and closing in the corners for optimal cornering performance. Battery Recharge: The system can replenish their battery with power recovered from braking, or during coasting at the conclusion of a straight or in sections where only reduced throttle is applied. Car Design Evolution The 2026 cars will be more compact and lighter than this year, with a car length shortened by 200mm to 3,400mm, overall width narrowed by 100mm – down to 1,900mm – and the car weight decreased by 30kg. Total aerodynamic grip is expected to drop by approximately 15-30%, although constructors will undoubtedly recover some as they refine their designs. Aerodynamic drag has been cut by 40%. The cars will feature adjustable aero systems – both wings will move on the straights to improve speed and increase straightline speed and return into place for optimal grip in corners. Wheels will retain 18-inch wheel rims, but the actual tyres will be slimmer, by a quarter-centimetre on the front and three centimetres on the rear. Power Unit Revolution The revised hybrid units will have an approximate 50-50 split in power produced by the ICE and the electrical system, increasing from about 20% battery contribution this year. The hybrid system is made less complex through the elimination of the MGU-H, the sophisticated and pricey unit that recovered energy from the turbo. Cars will be required to run on 100% sustainable fuel, produced using biomass or lab-created processes.
