Everything you need to know about F1's new rules for 2026

Formula 1's 2026 regulations mark a decade-defining revamp, introducing lighter, shorter, and narrower cars with revised aerodynamics. The cars will feature flatter floors, extended diffusers, and simpler, active front and rear wings that dynamically adjust to reduce drag on straights and boost downforce in corners, effectively replacing DRS. A significant shift in power unit design sees a 50-50 split between internal combustion and electric power, fueled by advanced sustainable fuels. New "Overtake Mode" and "Boost Button" offer drivers tactical tools, while enhanced safety measures and simplified MGU-H removal underscore the innovative, yet challenging, future of the sport, attracting new manufacturers like Audi and GM.
