Ferrari had one of the worst episodes of porpoising this weekend. It looks like other teams have reduced the effect.
Regarding the cause of porpoising, after observing it in three different races, on three different tracks, I think it is caused by a combination of aero PLUS a certain amount of pavement rippling. If it was just caused by the low underfloor pressure sucking the chassis down until the airflow stalls, then it should be speed dependent and happen on every fast straight.
But it seems to really happen when there is a combination of high speed plus some pavement issues. For Australia, the approach to Turn 9 seemed to be the worst place for porpoising, even though there were faster sections of track.
LeClerc/Ferrari were dominant on Sunday. He just pulled away from the pack, even Max. I think the Ferrari power unit is superior right now, as shown by the performance of the three teams using it. The difference in track position is probably more related to aero/chassis issues, as well as driver.
That said, I think that Mercedes made some power unit improvements this weekend, reflected by the performance of the Mercedes and McLaren teams, as well as Williams/Albon. Aston Martin has chassis, aero and reliability issues slowing them down, and Williams has Latifi.
