Mercedes puzzled by lack of progress from latest upgrades in Singapore

As was the case in Malaysia, the benefits of the upgrade package introduced at the previous Grand Prix were once again difficult to see around the streets of Marina Bay. Antonelli could only manage seventh place in Sprint Qualifying, finishing half a second behind his teammate despite running the newer specification of the W17.

By contrast, Russell appeared considerably more comfortable behind the wheel of the older-spec Mercedes, taking the fight to Max Verstappen for pole position. The Briton will line up alongside the Dutchman on the front row for Saturday's Sprint race, before serving his grid penalty in Sunday's Grand Prix.

Shovlin admitted that Mercedes remains unsure why its latest upgrade package is failing to deliver the expected performance gains. The demanding nature of the Marina Bay circuit, combined with the limited running available during a Sprint weekend, only complicated the team's efforts to find the optimal set-up. Although Russell's front-row result provided some encouragement, the significant performance difference between the two specifications left Mercedes with more questions than answers.

Shovlin also pointed out that neither driver felt entirely comfortable with the balance of the W17, although Antonelli struggled considerably more under braking and on corner entry, two crucial areas for extracting lap time around Singapore.

Mercedes now faces the task of analysing the data collected from both specifications to understand the performance gap, with the main priority being to improve Antonelli's confidence behind the wheel ahead of Saturday's Grand Prix qualifying session.

Antonelli admitted that the difficulties with Mercedes' latest upgrade package became apparent as early as FP1, with the Italian struggling to find a consistent balance throughout the day.

The unpredictable behaviour of the W17 made it particularly difficult to put together a competitive lap, leaving him frustrated after arriving in Singapore with high expectations. The 19-year-old also acknowledged that the team still has plenty to understand about the new components, which have so far failed to deliver the performance he expected.

Looking ahead, Antonelli conceded that the remainder of the weekend could prove extremely challenging unless Mercedes manages to find a breakthrough overnight. The Italian sees little room to recover the seven-tenth deficit through driving improvements alone, but remains hopeful that his engineers, including race engineer Peter Bonnington, can identify changes to unlock more performance. He also intends to work on his own driving ahead of Saturday's qualifying session, although he remains uncertain about how much progress the team can realistically make.
