Mercedes dig into data after Antonelli's W17 balance woes cost him at Zandvoort

Kimi Antonelli salvaged second place at the Dutch Grand Prix in Zandvoort, but Mercedes has launched a detailed data investigation after the championship leader struggled with a worsening balance problem across the second half of the race, finishing 11 seconds behind winner Lando Norris.

Antonelli made a bright start, jumping team-mate George Russell off the line from third on the grid to run second before the end of lap one. But as the race progressed, each tyre change brought fresh handling difficulties with his W17.

“It was really weird because I felt good with the medium. I felt decent on the first hard, but then on the second one it just felt really odd,” Antonelli said after the race.

Mercedes trackside engineering director Andrew Shovlin confirmed the team is now working through the data to identify the root cause. “Each tyre had a bit more oversteer than the tyre before it and we’re trying to understand why that was,” Shovlin said in the team’s post-race debrief. “We didn’t change the car, we didn’t add any aero balance, which is the sort of thing that could have explained it. So we’re having a real deep dive into the data and try and get to the bottom of that because it’s important to solve those sort of things ahead of the next race.”

Shovlin also acknowledged the broader competitive picture, noting that Mercedes is still awaiting a major upgrade package. “It’s obviously getting really tight now in terms of performance. We’re still waiting for our major update to land and that will help, but in the meantime it is going to be a bit of a fight.”

Antonelli said the deteriorating balance left him with “little confidence in the car” during the closing laps, when he was defending against Ferrari’s Lewis Hamilton and Charles Leclerc while also catching Russell on an offset strategy. Russell ultimately moved aside to allow his team-mate through, a gesture Antonelli was grateful for — though he acknowledged the call carried some risk.

“George, I have to thank him because he made my life a lot easier,” Antonelli said. “But I still think probably could have stayed out and gone until the end with the same set because it put us a little bit at risk. Also, I feel we put George at risk with having to let me by.”

Despite the difficulties, the result extended Antonelli’s championship lead. The Italian added that second place represented the ceiling of what was achievable on the day given McLaren’s pace. “The pace of the McLarens, especially in the second half, was just too strong.”

Mercedes will be hoping to resolve the issue before the Italian Grand Prix, which doubles as Antonelli’s home race.
