Key Highlights
- Mercedes opted to split specifications in Singapore, running an updated floor and sidepods on Kimi Antonelli’s car while George Russell reverted to the previous configuration.
- After an unpredictable Friday, a major setup overhaul helped Antonelli qualify fourth on Saturday, finishing within 0.189 seconds of polesetter Max Verstappen.
- Both Antonelli and Russell indicated that while the revised package shows promise, finding its narrow operational window remains a challenge ahead of the United States Grand Prix.
Mercedes Splits Aerodynamic Configurations in Singapore
Formula 1 championship leader Kimi Antonelli is confident that Mercedes’ upgraded W17 provides genuine performance steps, even as the team continues to decipher the exact operating window of the new components. In an atypical strategic move for a frontrunning squad, Mercedes decided to split its car specifications during the Singapore Grand Prix weekend. Antonelli was assigned the upgraded package—featuring a redesigned floor and modified sidepods—whereas teammate George Russell reverted to the older specification after taking penalties that consigned him to a back-of-the-grid start due to exceeding his power unit allocation.
The comparative data produced mixed signals early in the weekend. Russell appeared noticeably quicker during Friday’s sessions, outpacing Antonelli across sprint qualifying by roughly six-tenths of a second on average. However, the British driver subsequently suffered a crash in the sprint race, reporting that his car did not feel identical afterward. The challenge deepened when both Mercedes drivers struggled in Q1 on Saturday, placing 12th and 13th and sitting 1.2 seconds adrift of Lewis Hamilton’s benchmark.
Drastic Setup Changes Unlock Antonelli’s Qualifying Pace
Despite the early deficit, Antonelli managed the weekend’s most dramatic progression. The Italian driver trimmed two seconds off his earlier lap times to qualify in fourth position, trailing polesitter Max Verstappen by merely 0.189 seconds. The recovery marked a sharp turnaround from Friday evening, when Antonelli had characterized the modified W17 as “very difficult, very unpredictable and very difficult to put a lap together”
after the sprint qualifying runs.
Asked by Motorsport.com whether the subsequent sessions provided clarity, Antonelli confirmed the technical progress:
“Yes, yes, definitely.
“We start seeing what the package can give to us. However, it’s still difficult to find the right window. We did a big, big step in set-up today and we seem to put the car in a better place, even by giving away a bit of performance.
“But the car just seemed to work in a better way. However, the window was still very small, very sensitive, especially throughout qualifying – you know, when you try to push more and more with the track improvement, the car was reacting quite differently to any extra pushing, braking a little bit later, combining a bit more.
Advertisement“So the window is still very small, but the team did a great job on turning around and now we start to get some answers. If in Malaysia we were a bit lost, now we have the head a bit more clear.”
Antonelli expanded on the specific trade-offs required to make the Silver Arrow manageable over a single lap, revealing that the engineering crew traded ultimate aerodynamic performance for mechanical predictability:
“To be fair, we went completely opposite with the set-up and the car was in a happier place,” Antonelli explained.
“Yesterday the car was just sliding, it was sliding a bit everywhere, so just trying to stabilise a bit the car, giving away a little bit of aero performance, but just having a more stable platform.
“But still, even though it was better to drive, the window was still very small. But now we start to see what the package brings and the areas where we need to work on, and we are starting to get some answers, which is a good thing.”
Russell Cautious Over Package as Focus Shifts to COTA
While Antonelli’s fourth-place grid spot offered optimism, George Russell highlighted that Mercedes still sits away from its optimal competitive output. Russell observed the team’s ongoing need for development time to balance the car’s setup against the aerodynamic modifications:
“I mean, it was positive to see Kimi sort of more competitive today than yesterday,” the Englishman said. “However, we weren’t exactly lighting the timing screen on fire.
“As a team we’re still not satisfied with where we are with the new package. I think we recognise we need to make some set-up adjustments to compensate those changes, so maybe we can find a way to make it work and be fast. But right now we need more time.”
Antonelli agreed that further setup exploration is essential and pinpointed the upcoming round at the Circuit of The Americas in Austin as a clearer venue to evaluate the components across standard practice sessions:
“In Austin, obviously, we go back to a normal weekend, and I feel like we can explore a lot more,” the youngster said. “The best would be to have two cars on the same spec, because at least you can try very different things on both – because the team did a tremendous job on trying to bring this package and it has improved in certain areas, but definitely it has shifted the window in a different way.
“So, just need to keep working, keep exploring. But then I’m sure once we find the right window, then we’re going to be able to use the potential of the package.”
Why This Matters
In modern Formula 1, mid-season aerodynamic updates frequently alter ground-effect sensitivities, making modern floors and sidepods difficult to calibrate during compressed sprint race formats. By intentionally running split configurations between Antonelli and Russell, Mercedes adopted an aggressive engineering protocol to extract baseline comparison figures directly under competitive track conditions. While the narrower operating window temporarily created setup headaches, finding the performance threshold is vital for maintaining Antonelli’s position at the top of the Drivers’ Championship standings heading into the flyaway races at Austin and beyond.
Frequently Asked Questions
Why did Mercedes split setups between Kimi Antonelli and George Russell?
Mercedes chose to run the new floor and sidepod package exclusively on Antonelli’s car while leaving Russell on the previous specification. This direct back-to-back split provided real-world comparative telemetry, made feasible partly because Russell was already slated to start from the back of the grid due to power unit penalties.
What adjustments did Antonelli make to improve his qualifying position?
Following handling unpredictability on Friday, Antonelli and his engineering crew reversed their baseline setup direction. They sacrificed peak downforce performance to achieve a more compliant, stable platform, eliminating severe sliding and allowing him to extract a lap time within two-tenths of pole position.
Where does Mercedes plan to further assess this upgrade package?
The team plans to continue evaluating and refining the upgrade setup during the United States Grand Prix at the Circuit of The Americas, where a traditional grand prix schedule will offer extended practice time to explore wider setup windows.
