Mercedes had its fair proportion of growth points over the course of System 1’s ground-effect period, however after adopting versatile wings to assist get on high of its troublesome automotive the workforce says it wanted “a little bit of time to adapt” as soon as the FIA clamped down.
After scoring eight successive System 1 constructors’ titles, Mercedes kicked off the ground-effect period on the again foot in 2022. Its zero-pod idea was extra inclined to the porpoising phenomenon, and it was scrapping to catch up over successive seasons.
One resolution that the workforce explored to enhance the efficiency of its F1 racer was versatile wings, which trackside engineering director Andrew Shovlin says “labored fairly nicely”.
“Over the past couple of years, we had been struggling to get the automotive to show successfully in sluggish corners,” Shovlin defined. “A few of our rear tyre temperature points really got here from the truth that the drivers had been having to make use of the throttle to assist rotation. That led us right into a helpful growth path, permitting the entrance wing to bend.
“That helped in low velocity whereas giving a secure rear in excessive velocity, which labored nicely. Nonetheless, the FIA introduced in rules this 12 months that restricted that fairly considerably.”
System 1’s governing physique, the FIA, rolled out a clampdown on versatile wings over the course of the 2025 season. The transfer restricted the elasticity that was permitted in entrance and rear wings, with the hardest checks coming in over the Spanish Grand Prix weekend.

The checks impacted every workforce in another way, with some predicting that it could clip McLaren’s wings and finish its dominance – however this prediction didn’t materialise. The brand new checks did, nevertheless, hamper Mercedes.
“It took us a little bit of time to adapt after these guidelines got here in at Barcelona,” Shovlin added.
“While you’re not the quickest automotive, you take a look at who’s and what they’re doing. We checked out McLaren’s rear suspension and will see what they had been attempting to do with anti-lift to maximise how low they may maintain the rear right into a nook.”
The problem that led Mercedes to peruse the versatile wing thought was simply one among a myriad that the German workforce confronted when F1’s guidelines modified in 2022. And whereas Shovlin doesn’t go as far as to say Mercedes “underestimated” the change, he admits that it “didn’t put sufficient effort” into some elements of the rules.
“Coming into these rules, we wouldn’t say we underestimated the problem of getting through-corner stability – stability on entry, rotation on the apex, and good traction on exit – however we clearly didn’t put sufficient effort into carrying over the strengths of the 2020–2021 automobiles,” Shovlin stated.
“Now, everyone seems to be doing comparable speeds via corners. The distinction is how nicely your stability fits a given circuit, which is what’s separating groups for the time being.”
Mercedes is now gearing up for F1’s subsequent regulation shift in 2026 when new guidelines will dramatically alter the automobiles and their energy items. Whereas Shovlin admitted that the workforce nonetheless had “a whole lot of work to do”, he conceded that the approaching change was now “much less daunting than a month in the past”.
