Key Highlights:
- Broadcaster Will Buxton revealed that Mercedes team principal Toto Wolff suspects the team’s extensive floor and sidepod upgrade may have cost them four to five tenths of a second per lap instead of delivering expected gains.
- Introduced to boost medium-to-high speed downforce, the revisions targeted a three-tenths improvement, but performance fell short during the race weekend at Sepang International Circuit.
- Mercedes is expected to conduct back-to-back testing between old and new specifications in Singapore, despite the logistical challenge of having only one practice session during a sprint weekend.
Mercedes Faces Setback as Major Technical Upgrades Backfire
Mercedes’ pursuit of front-running pace has encountered a significant roadblock following revelations about the team’s latest aerodynamic development path. Formula 1 broadcaster Will Buxton has voiced concerns regarding the Brackley outfit’s revised package, indicating that team principal Toto Wolff fears their newest floor and sidepod package may have dramatically hurt lap times rather than helping them.
The Silver Arrows arrived at the Sepang International Circuit having overhauled nearly every aerodynamic body surface on their challenger. The modifications focused heavily on generating enhanced downforce through medium-to-high speed corners, a design choice accepted with the compromise of shedding a marginal amount of straight-line velocity. However, trackside reality quickly conflicted with pre-event computer simulations and wind tunnel projections.
Buxton Details Disappointing Performance at Sepang
During the race weekend in Malaysia, Kimi Antonelli qualified in third position while George Russell managed only seventh. On Sunday, Antonelli secured a second-place finish, whereas Russell suffered a retirement driven by a power unit problem. Despite Antonelli’s podium finish, Buxton pointed out that Mercedes lacked the outright speed required to challenge for victory.
Discussing the situation on the Up To Speed podcast, Buxton assessed Russell’s misfortune and the wider technical mystery engulfing the Brackley squad:

“Obviously, the DNF is something out of his control, but Mercedes never looked like they were in the mix for the fight,” Buxton said.
“They had a big upgrade. Is it a case, and I guess we may only know this weekend, but do we feel it’s a case of the upgrade hasn’t worked or that it was track-specific and that they didn’t get what they wanted out of it?
“Because for those who don’t know, big upgrades on things like the floor and the sidepods, and they were adding a little bit of downforce to the car, which meant they would have lost a little bit of straightline speed, but it should have paid back through the corners. They were expecting to gain about three tenths of a second. As it is, Toto thinks they may have lost around four or five [tenths].
Advertisement“So, not a gain, potentially a loss. I think they’re going to run back-to-back tests in Singapore between the old spec and the new spec. But there’s only one practice session because it’s a sprint weekend.”
Why This Matters
In modern Formula 1, finding three tenths of a second can be the deciding factor between securing pole position and languishing in the midfield. For Mercedes, suffering an estimated net swing of nearly eight tenths away from expectations represents a severe correlation issue between factory simulations and real-world asphalt dynamics.
The impending challenge in Singapore adds operational pressure to the engineering staff. Because the event follows a sprint weekend schedule, Mercedes will be restricted to a single 60-minute practice session to conduct comparative evaluations between their previous aerodynamic kit and the new setup. Making rapid diagnostic choices under tight parc fermé deadlines will dictate whether the team can preserve their competitiveness or if they must revert to earlier configurations for the remainder of the campaign.
Frequently Asked Questions
What specific components were updated on the Mercedes car?
Mercedes brought major technical updates primarily focused on the car’s floor and sidepod geometry, resulting in alterations to virtually every aerodynamic body surface in an effort to generate greater downforce.
How much lap time did Mercedes lose compared to expectations?
While the team anticipated a lap-time gain of roughly three tenths of a second, Toto Wolff suspects the package may have actually resulted in a deficit of four to five tenths, producing an adverse performance swing.
How will Mercedes test the new parts at the Singapore Grand Prix?
According to Will Buxton, Mercedes plans to run back-to-back comparison tests between the old specification and the new specification during the opening track action in Singapore, though evaluations will be constrained by the single practice session of the sprint format.
