F1’s technical regulations for the 2022 and 2023 seasons have seen some changes as the sport attempts to counter concerns over the porpoising of the new generation of cars. Changes have been made with “safety” in mind and after consultation with all teams on the matter.
On the eve of announcing the changes, FIA President Mohammed Ben Sulayem stressed how safety was the FIA’s top priority and that the team had spent a lot of time and resources finding the best possible solutions. He said:
“Safety is absolutely the highest priority for the FIA, and we have devoted a lot of time and resources to analyzing and resolving the porpoise problem.”
He further added:
“I have personally discussed this matter with all the teams and all the drivers, and although there are of course differences of opinion due to varying competitive positions, it is very clear that the FIA has a duty to action and to ensure that pilots are not exposed to undue risk of injury as a result of this phenomenon.”
Apart from the issue of porpoising which has become a hot topic in F1 at the moment, the FIA President also spoke about Guanyu Zhou’s crash at Silverstone and the lessons learned by the FIA which made a chance in the hoop compulsory. . He said:
“It was obvious that an update to the requirements for roll bars was needed after Zhou Guanyu’s crash at Silverstone, and while that incident showed us all just how critical safety systems in Formula 1 are remarkable, it also proved once again that we must continue to innovate and pursue security issues without compromise.
Changes to the F1 Technical Regulations
As shared by the FIA, it will measure the phenomenon and expect teams to operate below a certain threshold for their car to be considered safe.
In addition, the following measures are approved for 2022 and 2023:
F1 2022 Technical Regulations
- Center Floor Flexibility – changes to redefine plank and runner stiffness requirements around thickness measurement holes.
F1 2023 Technical Regulations
- The edges of the floor will be raised by 15 mm.
- The height of the diffuser throat will be raised, while taking care to avoid any impact on the design of the mechanical components by the teams.
- The rigidity of the edge of the diffuser will be increased.
An additional sensor will be mandated to more effectively monitor the phenomenon.
Hoop changes for the 2023 F1 season
Another safety change was the disintegration of the roll bar in Guanyu Zhou’s crash at Silverstone this season. For the 2023 F1 season, the following changes have been introduced:
- A change to require a rounded top of the roll bar, which will reduce the risk of it digging into the ground in a crash.
- A change to ensure a minimum height for the point of application of the homologation test.
- Created a new physical homologation test where the load pushes the hoop forward.
- Definition of new tests to be carried out by calculation.
It will be interesting to see what kind of impact these regulations will have on the pecking order as well, and the impact could be visible as early as the Belgian GP after the summer break.
