Ross Brawn is a “little surprised” that the teams have been caught out by porpoising as it goes hand-in-hand with ground effect aerodynamics.

Taking to the Circuit de Catalunya last week, most of the drivers complained about their 2022 cars bouncing up and down on the straights.

It is a phenomenon known as porpoising, a consequence of using ground effect aerodynamics.

The car is pushed down onto the track by the downforce and, as it gets closer to the ground, the causes the underfloor aero to stall.

When that happens the car rises off from the track, which leads to the underfloor aero kicking in, and again the car is pushed into the ground.
