🔗 Share this article Overtake Mode & Active Aero - Understanding F1's New Technical Terminology The 2026 cars are designed to be lighter, more agile and sustainable compared to current models. F1 has unveiled the simplified terminology that will be used to reference the advanced features of its new 2026 regulations. The championship is implementing what is arguably the most significant rules overhaul in its illustrious history next season, featuring new chassis and engine rules and the mandatory use of fully sustainable fuels. The new power units, which keep the 1.6-litre V6 configuration, boast a significantly increased battery power, necessitating significant developments in the cars' aerodynamics. During grand prix events, competitors will tactically deploy battery power – potentially on flying laps – to secure the optimal lap time. Broad surveys were conducted with a wide range of fans, including long-time followers and newcomers, to identify which terms would aid comprehension of the main elements of the upcoming rules. The key objective was to render a series of complex technical aspects of the competition as straightforward as possible for the broadest viewership. Consequently, previous placeholder terms for certain devices – such as "alphabetical mode names" for the adjustable aero – have been discarded in preference for straightforward terms that succinctly convey the actual function of the innovation. Key Technical Innovations The FIA states that racers will have more power to make decisions regarding energy deployment, regeneration, and saving energy. The new regulations mandate a set of functions that will be clearly indicated on television graphics to aid the audience's understanding of the race battle. Passing Mode: This replaces the present overtaking aid. It provides a burst of extra electrical energy deployable when a competitor is less than a second the vehicle in front to facilitate an overtake. Extra Push Mode: This is a manual energy deployment from the ERS that can be used in overtaking or defending. It delivers the driver maximum power at the click of a switch. Both of these crucial modes will have to be used with calculation, as the total energy is restricted. Active Aero: Both the front and rear wings adjust their angles – spreading on the straights for minimal air resistance and increased velocity, and closing in the corners for peak grip. Recharge: The system can recharge the energy store with power recovered from braking, or during throttle lift at the straight's end or in corners where only partial power is required. Car Design Evolution The next-generation machines will be reduced in size and weight than this year, with a car length reduced by 200mm to 3,400mm, width narrowed by 100mm – down to 1,900mm – and the lowest permissible weight lowered by 30kg. Total aerodynamic grip is expected to drop by approximately a significant margin, although squads will naturally regain performance as they refine their designs. Air resistance has been reduced by 40%. The cars will feature active aerodynamics – front and rear wings will open on the straight sections to improve speed and increase straightline speed and return into place for optimal grip in corners. Pirelli tyres will keep the current rim size, but the actual tyres will be reduced in width, by 25mm at the front and three centimetres on the rear. Power Unit Revolution The new power units will have an approximate 50-50 split in horsepower generated by the internal combustion engine and the battery and motor, up from about one-fifth electric power in the current formula. The hybrid system is made less complex through the removal of the Motor Generator Unit – Heat, the sophisticated and pricey component that recovered energy from the turbocharger. Every car on the grid will be mandated to operate on fully sustainable fuel, created from organic sources or synthetic production methods.
