Rumors continue about the rules that will determine the next regulatory cycle for Formula 1 cars. Among the latest is the possibility of a lighter Halo for the 2026 cars.
Formula 1 is approaching a revolutionary regulatory cycle, with cars powered by hybrid engines running on 100% biofuels. Besides this innovation, the most discussed change is the equal power distribution between the electric and thermal parts. Meanwhile, teams are still waiting for the chassis rules, as the FIA is considering other modifications for 2026, including a lighter Halo.
Over the years, the cars have significantly increased in weight, reaching the critical threshold of 800 kg. With the advent of new technical regulations, the FIA aims to reverse this trend, significantly reducing the mass of the world’s fastest cars. In recent months, there has been talk of lighter tires, smaller cars, and reducing the elements of the power units. The most recent topic is active aerodynamics, which currently seems to create more problems than solutions.
To further reduce the weight of the cars, the FIA has opened a tender for the design and manufacture of a lighter Halo for 2026. The task for the winning bidder is not simple, as the current version, in use since 2018, weighs only 7 kg. The models in use are made of titanium and have the fewest possible welds to reduce weak points. This structure, anchored at three points to the chassis, can withstand a maximum load of 12 tons.
The task for the tender winners is quite complex: they must “slim down” the current structure by about 1 kg while maintaining the same safety standards. Once the manufacturer is chosen, the company will be responsible for supplying the top series for the period from 2026 to 2030.
