Formulation 1’s chief technical officer Pat Symonds believes the game’s governing physique went too far in its bid to scale back ‘porpoising’ after the Azerbaijan Grand Prix.
The FIA launched a collection of guidelines modifications in response to the punishment some drivers suffered from the bouncing their automobiles skilled following the introduction of closely revised rules this 12 months. Lewis Hamilton specifically was visibly pained by the tough trip he endured on the Baku Metropolis Circuit.
A brand new metric limiting how a lot automobiles might bounce was launched by the FIA. For 2023 the bodily dimensions of the automobiles’ flooring is being modified in an effort to lowered the ‘porpoising’ phenomenon. However Symonds believes the modifications go too far.
“I feel they overreacted a bit after Baku,” he advised Auto Motor und Sport. “In Baku we noticed the worst impression as a result of a workforce tried one thing that didn’t work after which went public fairly loudly.
“Had they not intervened, the issue would have been solved. Most groups now perceive easy methods to management bouncing.”
Because the season progressed groups comparable to Mercedes more and more mastered their porpoising issues. Nevertheless it remained an element at some circuits, together with Yas Marina, scene of the season finale.
Symonds, who has many years of expertise as an F1 engineer, admitted he had did not anticipate the issue when he and his workforce drew up the bottom impact guidelines which the FIA launched in 2022.
“I’ve to confess, it wasn’t on our radar,” he stated. “However we should always have had [foreseen] it.
“We had the flexibility to find it beforehand as a result of we labored with dynamic simulations. For instance, we used them to verify what occurs when a automobile spins and will get air underneath it. So the kind of accident that Mark Webber as soon as had in Valencia. This requires particular software program that we may have used to anticipate and perceive the bouncing.

“I ought to have identified too, as a result of I used to work on floor impact automobiles. I had merely forgotten. For sure, bouncing modified issues. The groups first needed to clear up this drawback earlier than they may work on their aerodynamics. Bouncing shouldn’t be purely an aerodynamic drawback. Loads of mechanics additionally play a job, for instance the suspension stiffness.”
Some points of groups’ designs additionally got here as a shock to him, together with Mercedes’ radical ‘zero-pod’ idea and an aggressive rear wing utilized by Aston Martin which Symonds suspects will quickly be outlawed.
“We couldn’t see something on the automobiles that might have broken our idea,” he stated. “A couple of issues had been undoubtedly extra radical than we thought.
“For instance the Mercedes. We later examined and reviewed the idea in CFD and I’ve to say that the form of the Mercedes is less complicated to observe than the opposite automobiles.
“The Aston Martin rear wing was additionally one thing we didn’t anticipate. I see a danger on this concept that it may go the mistaken manner if the concept is pursued additional and pushed to the restrict. I anticipate the FIA will ban that for 2023.”
F1’s greatest groups loved probably the most success underneath the brand new guidelines. Solely a single podium for McLaren’s Lando Norris at Imola prevented Crimson Bull, Ferrari and Mercedes from sweeping the podium locations throughout 2022.
Symonds admitted the completion wasn’t as shut as he anticipated underneath the brand new guidelines however is hopeful that may change subsequent 12 months. “We underestimated that some groups nonetheless have giant aerodynamics departments that bought extra out of the brand new guidelines,” he stated.
“However we’re hopeful that the hole from entrance to again will slender rapidly. This might already be noticed to a small extent through the season.”
