FIA eases porpoising limits for Singapore Grand Prix

The FIA will reportedly make revisions to porpoising measurements for the Singapore Grand Prix at a typically bumpy Marina Bay Circuit.

With the return to ground-effect challengers for 2022, several teams initially ran into a bouncing issue with their cars, termed porpoising.

Mercedes in particular struggled with this phenomenon but by the Azerbaijan Grand Prix, round eight of the season, several drivers had raised safety concerns about the porpoising after an uncomfortable drive in Baku for many of them.

Answering the calls for intervention, the FIA acted by introducing an Aerodynamic Oscillation Metric which the teams must stay within, or risk exclusion from the sprint or race classification.



The ruling came into effect at the Belgian Grand Prix, although according to Autosport, the FIA have recognised the nature of the Singapore track could impact the ability of the teams to stay within this limit.

The Marina Bay Street Circuit, to which Formula 1 returns for the first time since 2019, has developed a reputation for being among Formula 1’s bumpiest tracks.

Autosport state F1’s head of single-seater matters, Nikolas Tombazis, has written to teams to confirm the metric will be tweaked for Singapore as the bumps risk triggering a measurement that would mean the teams fall foul of the ruling when they had not done anything wrong.

A top limit of 7G for all readings has been introduced, meaning anything above that will not be taken into consideration.

Bumpy tracks do not often bode well for Mercedes, a blow for Lewis Hamilton who has only six rounds left to extend his record of winning a race in every Formula 1 season he has contested.

The Mercedes W13 challenger has been very inconsistent throughout the season, so Hamilton is not going into the Singapore Grand Prix with any set expectations.

“We hope the car works better here,” Hamilton told reporters ahead of the race weekend. “But it really depends how bumpy it is.

“The bumps often set the car off and upset the car in a lot of instances. So we know it will be bumpy – maybe the car will be fine, maybe it won’t.

“So I have no expectations, we will just try to have the best weekend with whatever we are faced with.”
