F1’s transfer to the present ground-effect guidelines set in 2022 was prompted by a need to permit automobiles to comply with a lot nearer to one another.
One of many core options of the laws was to minimise groups pushing airflow away from the automotive and tyres – often called outwash – as a result of this wake disturbance contributed to a lack of downforce for pursuing automobiles.
However as groups have gotten to grips with the brand new laws, there was an elevated push to maximise outwash traits, particularly via intelligent design of the entrance wings.
It’s this strategy which is known to have contributed to the 2023 automobiles being tougher to comply with than their 2022 counterparts.
Earlier this yr, it was estimated that there was a 35% lack of downforce when rivals are two automotive lengths behind a rivals – up from 20% in 2022.
Whereas initially there had been some thought given to creating some rule adjustments for 2025, the FIA’s single seater director Nikolas Tombazis has now defined that strikes to kind out the issue will now more likely to wait till the following guidelines period from 2026.

“The wake has undoubtedly received a bit worse this yr,” mentioned Tombazis.
“We knew that it will deteriorate a bit when individuals developed a bit extra, however there have been a couple of specific areas of the automotive the place there have been some loopholes we did not handle to shut quickly sufficient. This worsened it.
“The entrance wing endplate space was one [area], plus a number of the wheel furnishings space, and brake ducts inside the entrance wheel.
“I believe we have discovered a bit the right way to do it subsequent time round. However whereas the wake did get a bit worse in comparison with 2022, it’s nonetheless an affordable quantity higher than 2021.”
Pushed on the timings of eliminating these loophole areas, Tombazis mentioned: “I might say most likely ’26. We have no intentions to vary for’ 25 except something unpredictable occurs.”
Whereas there was a step change in downforce loss when following this yr, Tombazis believes that issues have now stabilised.
“I do not suppose it will get a lot worse for subsequent yr as a result of I do not suppose there’s every other loopholes to scrape from, just like the entrance wing space and so forth,” he mentioned.
“Due to this fact, I count on it will keep very comparable. I additionally do not suppose it is received worse through the yr. I believe it was simply this yr versus final yr.”
