F1 News: FIA published revised 2025 & 2026 Technical Regulations

Following the World Motor Sport Council meeting in Rwanda, the FIA has issued revised 2025 Formula 1 Technical Regulations and also revealed revised regulations for 2026 F1 Technical Regulations centered around Active Aero components.

Once the FIA’s official weather systems predict temperatures over 30.5C (or when called by the race director prior to an event, a ‘heat hazard’ will be declared. This will require the teams to equip the drivers with their cooling systems, and the minimum weight will be raised by 5kg.
the slot gaps for the rear wing between the two modes of the DRS have been changed, to thwart any attempts by McLaren to replicate the “mini-DRS” cheat trick used by McLaren in 2024
The minimum gap has shrunk from 10-15mm to 9.4-13mm and, with DRS open, the upper boundary remains at 85mm.

There are two active aero flaps on the front wings – one for cornering, one for straight-line use. They include physical stops to stop the wing elements from rotating more than the required amount. However, it does not stop the elements from deforming or flexing in one setting vs the other.
Small winglets may now be applied to the outside of the front wing end plates
Whereas previously the rear wing had to be three elements, the revised regs say “up to three.”
Whereas the bottom element of the rear wing cannot be rotated for active aerodynamics, the remaining elements can be
A floor sidewall has been detailed, along with winglet and fence bodywork, to increase the downforce generated by the new design.
Deflectors and a ‘debris guard’ is now permitted around the wheels
A whole host of wheel drum tweaks
Changes to the static tests of the wings to reduce the chances of excessive flexing
Body and floor and floor plank flexing requirements
Floor Board and Diffuser flexing regs are yet to be defined
