Antonelli Casts Doubt on Mercedes Upgrade Package in Singapore

Kimi Antonelli has added to the growing doubts about how well Mercedes' latest upgrade package is working. The World Championship leader said his car was "very difficult" to drive during Sprint Qualifying in Singapore, a comment that goes beyond the usual post-session shrug and points at the new parts themselves.

Sprint Qualifying is a short, hard-charging session where drivers need the car to respond instantly over a single lap. A car that feels unpredictable at that stage can cost a driver time that carries straight into the weekend's grid. Antonelli's frustration suggests the package has not delivered the straightforward gain the team would have wanted, at least not in a form he can reliably use.

It is worth keeping this measured. One session's comments do not settle whether the upgrades are a step forward or a step back, and drivers often describe a car as difficult when set-up, tyre behaviour or track evolution are also in play. Even so, the Marina Bay street circuit is a demanding track where balance problems are quickly exposed, and the fact that the championship leader chose to raise the issue publicly will not have gone unnoticed inside the team.

For Mercedes, the central question is whether the problem lies in the package itself or in how it is being set up for this venue. For Antonelli, the picture is simpler. He is leading the championship, and any sign that his car is hard to handle at the limit will be watched closely by rivals as the season moves toward its closing rounds.
