PARIS, France — The Fédération Internationale de l’Automobile (FIA) has formally announced a comprehensive overhaul of Formula 1 technical regulations, set to take effect in the 2026 season.
The changes target key areas of car design, performance, and environmental impact, aiming to make the sport safer, more competitive, and more sustainable.
Among the adjustments is a reduction in car size. The maximum wheelbase will decrease by 200mm, bringing it to 3,400mm.
Cars are also expected to become lighter and more agile, enhancing cornering performance. The new regulations will introduce dual configuration modes, allowing drivers to choose between settings that either prioritize fuel efficiency or optimize handling and grip.
The FIA confirmed that changes to power units will remove the MGU-H (Motor Generator Unit – Heat) component and substantially increase the output of the MGU-K (Motor Generator Unit – Kinetic).
Under the 2026 framework, MGU-K output will rise from 120kW to 350kW, and regenerative braking capacity will double to approximately 8.5 megajoules per lap.
The regulations also call for major aerodynamic revisions, with a strong focus on reducing drag. Active aerodynamic components will be implemented to help manage airflow and reduce resistance, particularly on straights.
The introduction of these new standards has already prompted some teams to shift development priorities from their 2025 cars to the 2026 designs.
With the removal of certain components and a renewed emphasis on electrical power, the FIA expects vehicles to feature a more even 50/50 split between internal combustion and electric propulsion.
However, early simulations suggest that such a power balance may result in a temporary drop in top speed, particularly on long straights.
These projections have sparked concerns among stakeholders that F1 cars in 2026 could fall behind their Formula 2 counterparts in terms of performance.
Despite these worries, the FIA has defended the regulation package, stressing that safety, efficiency, and environmental considerations are at the core of the overhaul.
Officials acknowledge ongoing discussions within the F1 community about overtaking potential and race dynamics under the new format but remain confident in the long-term vision.
The new regulations are part of the FIA’s broader commitment to achieving net-zero carbon emissions by 2030 and adapting the sport to align with global automotive trends, particularly the shift toward electrification and energy efficiency.
With two seasons remaining before implementation, teams will continue to evaluate how the 2026 rules will shape car development and competitive strategies moving forward.
