🔗 Share this article Active Aero & Overtake Mode - Decoding F1's New Technical Terminology The 2026 Formula 1 cars are set to be more compact, agile and eco-conscious than this year. The world of Formula 1 has unveiled the simplified language that will be used to reference the technical complexities of its revolutionary 2026 technical rules. The sport is introducing what is considered the biggest rules overhaul in its illustrious history starting in 2026, featuring fresh chassis and power unit regulations and the mandatory use of 100% sustainable fuels. The updated 1.6-litre V6 turbo hybrids, which maintain the 1.6-litre V6 turbo hybrid, boast a significantly increased battery power, requiring major innovations in the cars' aerodynamics. Over a race distance, drivers will carefully oversee electrical energy – including during qualifying laps – to secure the best lap time. Extensive fan consultation were carried out with a diverse audience, including new, casual and core fans, to understand which terminology would improve understanding of the central aspects of the upcoming rules. The key objective was to render a set of intricate new areas of the sport as easy to grasp as possible for the global fanbase. Consequently, older technical labels for specific components – such as "alphabetical mode names" for the moveable wings – have been discarded in preference for intuitive labels that succinctly convey the actual function of the innovation. What's the New Technology? The FIA states that competitors will have more power to determine tactics regarding battery management, regeneration, and efficiency. The new regulations feature a series of modes that will be visually displayed on TV overlays to aid the fans' insight of the on-track action. Passing Mode: This replaces the current DRS. It provides a surge of additional ERS power accessible when a competitor is less than a second the leading car to assist with an overtake. Boost Mode: This is a on-demand energy deployment from the ERS that can be used in overtaking or defending. It grants the driver peak output at the click of a switch. Both of these crucial modes will have to be managed carefully, as the overall battery capacity is strictly limited. Adjustable Aero: Both the car's wings change configuration – flattening on the straights for reduced drag and increased velocity, and sealing in the corners for optimal cornering performance. Energy Harvesting: The system can harvest energy with power recovered from braking, or during throttle lift at the end of straights or in sections where only limited engine output is required. Car Design Evolution The next-generation machines will be more compact and lighter compared to the 2025 spec, with a wheelbase shortened by 200mm to 3,400mm, width cut by 100mm – down to 1,900mm – and the car weight reduced by 30kg. Total aerodynamic grip is projected to decrease by approximately a significant margin, although constructors will naturally regain performance as they refine their designs. Drag has been slashed by 40%. The vehicles will employ adjustable aero systems – both wings will open on the straight sections to improve speed and enhance velocity and return into place for maximum cornering performance. Pirelli tyres will keep 18-inch rims, but the actual tyres will be reduced in width, by a quarter-centimetre on the front and 30mm at the rear. 2026 Engine Regulations The new power units will have an roughly half-and-half distribution in horsepower generated by the petrol engine and the electrical system, up from about 20% electrical this year. The hybrid system is simplified through the deletion of the Motor Generator Unit – Heat, the intricate and expensive component that generated electricity from the exhaust turbo. All vehicles will be required to run on 100% sustainable fuel, created from organic sources or synthetic production methods.
