FIA eases F1 porpoising metric from Singapore GP
Formula 1’s porpoising metric has been tweaked from this weekend’s Singapore Grand Prix to help remove potential problems caused by bumpy tracks, Motorsport.com has learned.

As the result of the extreme bouncing earlier in the season that left drivers complaining about safety implications, the FIA announced ahead of the Canadian Grand Prix that it was introducing an Aerodynamic Oscillation Metric that teams would not be allowed to exceed.
Teams had to ensure that their car was below the maximum bouncing limit over each lap, or there was a risk of them being sanctioned on safety grounds.
In a document sent to teams ahead of the Montreal race, they were warned that breaching the rules would carry the risk of cars being excluded from events.
F1’s head of single seater matters Nikolas Tombazis said in that note: “Any car whose AOM exceeds the stipulated AOM [limit] will be reported to the stewards with the recommendation that they be excluded from the results of the sprint or race."
Following some debate with teams about the implications of the metric, it finally came in to force from the Belgian Grand Prix.
By that stage of the campaign, with teams having a much better understanding of the forces that triggered much of the early season porpoising, no team has fallen foul of the metric so far.
However, there had been some concern that some of the end of season races on bumpier tracks – including Singapore and Austin – could have triggered particular headaches.
