The FIA World Motorsport Council has approved changes to Formula 1’s technical regulations for 2022 and 2023 to solve the problem of car build-up. In addition, the requirements for the upper safety arch have been increased.
Starting with the Belgian Grand Prix, the FIA will measure yaw and require teams to change settings to keep it below certain values. The following changes have been made to the scheme:
In 2022: The requirements for the rigidity of the elements of the underside of the machine and the wear limit of the control bar have changed.
In 2023: The minimum ground height above the track surface is increased by 15 mm. Increased stiffness of the diffuser. An extra sensor will be installed on the machines for effective monitoring of the superstructure.
In addition, following Guanyu Zhou’s accident at Silverstone, when the top safety arc broke after the car overturned, the requirements for its form and strength were raised in the regulations for the 2023 season.
In particular, the upper part of the ROPS will be more rounded, strength tests during homologation will have to be performed at a higher point and in 2014 the ROPS strength requirements will be significantly revised to withstand even heavier loads in the future.
