The FIA details next steps for their ‘anti-porpoising’ directive

The FIA has announced it has “defined a metric by which to monitor” vertical oscillations of the cars, and gives the teams time until the French Grand Prix “to be compliant” with the technical directive.

Ahead of the Canadian Grand Prix, the FIA introduced a technical directive aimed at reducing the porpoising phenomenon, under safety grounds.

The first order of business was data collection so that a metric, that will be used to monitor vertical oscillations of the cars, can be established.

The FIA has now announced the next steps.

“In connection with safety concerns previously raised by the FIA regarding the vertical oscillation [porpoising] of the new generation of Formula 1 cars, the FIA is now taking the next steps to address this issue and has sent a draft update to the technical directive issued prior to the Canadian Grand Prix to the teams,” the FIA said in a statement.

“The FIA’s analysis of vertical oscillation data has concluded, and we have defined a metric by which to monitor this – the update has been sent to teams to allow them to conduct their own analysis over the next two grands prix to understand what, if any, changes they may need to implement in order to be compliant when the technical directive becomes effective as of the French Grand Prix.

“Additionally, the technical directive also sets out some updated parameters relating to plank wear and skid stiffness, which are inherently related to the same issue, and go hand-in-hand with the metric,” the statement concluded.

“These changes are necessary in order to provide a level playing field between the teams when the metric is implemented.”
