Andrea Kimi Antonelli has opened up about the turbulent middle phase of his debut Formula 1 campaign, revealing that Mercedes‘ unsuccessful suspension experiment effectively stalled his progress for several months. The 18-year-old Italian, who joined the Silver Arrows amid considerable fanfare as Lewis Hamilton‘s long-term successor, found himself wrestling with a car setup that exposed his inexperience at the sport’s highest level.
The Imola upgrade that backfired
Mercedes arrived at the Emilia-Romagna Grand Prix in May with a revised rear suspension geometry, hoping to address persistent rear tyre temperature struggles and unlock better low-speed performance. The technical direction drew inspiration from McLaren’s dominant MCL39 package, which had set the benchmark for rear-end design throughout the early season.
However, the modification introduced significant instability at the rear of the W16, creating a platform that proved particularly challenging for a driver still finding his feet in Formula 1. While George Russell, with years of grand prix experience behind him, managed to adapt his driving style to mitigate the worst effects, Antonelli struggled to find any rhythm as the European leg of the championship began.
A confidence crisis unfolds
The timing could hardly have been worse for the Mercedes newcomer. After showing genuine promise during the opening flyaway races, Antonelli’s form collapsed precisely when consistency mattered most. The rookie found himself trapped in a downward spiral, driving with increasing tension as confidence evaporated with each difficult session.
“I think I’ve lost a good two or three months of progress,” Antonelli admitted when reflecting on the period. “Obviously, I struggled with the rear end more than George. I struggled more to adapt, mainly to do my driving style.”
The Italian described the experience as particularly frustrating because he felt powerless to arrest the decline. “It was a difficult period because I just kept losing confidence, driving super tense and I just really struggled to make any progress,” he explained. Had either a quicker adaptation or an earlier reversion to the previous suspension specification occurred, Antonelli believes he could have rebuilt momentum far sooner in the season.
The path back to form
Mercedes eventually acknowledged the update had not delivered the intended benefits and reverted to the original suspension configuration. For Antonelli, the change marked a turning point. Freed from the unpredictable rear-end behaviour that had defined his mid-season struggles, the young driver gradually rediscovered his natural speed and began posting results that justified the faith Mercedes had shown in promoting him directly to the senior team.
Andrew Shovlin, Mercedes’ trackside engineering director, has watched Antonelli’s evolution with satisfaction despite the setback. The senior engineer highlighted qualifying performance as the area where the Italian has made the most significant strides, having initially shown stronger pace in race trim than over a single lap.
“We expected long runs to be the hardest, but he was strong there immediately,” Shovlin noted. “Single-lap performance took more work. Learning to trust the tyres and generate temperature early was key.”
Learning the hard lessons
Shovlin emphasised that Antonelli’s technical feedback has remained consistently strong throughout his debut season, even during the difficult middle months. The ability to articulate what the car is doing represents one of the most valuable skills any driver can possess, and the Italian arrived with that foundation already in place.
The bigger challenge has been building the mental database that separates experienced racers from newcomers. Understanding how setup changes translate to on-track behaviour, knowing precisely how hard to push in different phases of qualifying, and avoiding the costly mistakes that come from either over-confidence or excessive caution all require time to master.
Budapest provided a stark lesson in the dangers of overdriving, while several late-season qualifying sessions saw Antonelli push too hard in Q3 after strong earlier runs. Yet Shovlin sees these as natural growing pains rather than fundamental flaws. “What’s good with Kimi is that once he learns something, it sticks,” the engineering director observed. “He’s not repeating the same mistakes.”
What this means going forward
As Antonelli heads into his second Formula 1 season, the lessons learned from the suspension debacle should serve him well. The experience of fighting through a major technical setback while under the microscope of one of the sport’s most scrutinised teams has accelerated his development in ways a smooth rookie campaign never could have done.
Mercedes remains confident in its long-term investment, with Shovlin confirming the team is “very much on track” with the Italian’s progress. The final races of his debut year suggested Antonelli has the raw speed and learning capacity to become a genuine championship contender once he accumulates the experience currently separating him from established performers like Russell. Whether those lost months ultimately matter in the broader arc of his career will depend on how quickly he can convert painful lessons into consistent podium finishes.
