2022 and 2023 porpoising and roll hoop regulations approved
The WMSC also approved changes to the 2022 and 2023 Technical Regulations, designed to address both the issue of aerodynamic porpoising and of safety standards for roll hoops.
With regards to porpoising, it has now been approved that from this month's Belgian Grand Prix until the end of the season, there will be changes to re-define the stiffness requirements of the plank and skids around the thickness measurement holes on the cars – in addition to the changes already signalled by a Technical Directive issued to the teams ahead of the summer break.
From 2023, meanwhile, the following changes will be made:
- The floor edges will be raised by 15mm
- The diffuser throat height will be raised
- The diffuser edge stiffness will be increased
- An additional sensor will be mandated to monitor the porpoising phenomenon more effectively
