Mercedes faces early W17 challenges as testing issues disrupt Bahrain running
Mercedes' preseason preparations hit a snag in Bahrain as the W15 faced delays and a suspension issue, limiting running for George Russell and Kimi Antonelli. Engineering chief Andrew Shovlin admitted the team is still understanding the car's behavior amid balance and consistency problems, marking a rocky start compared to their smooth Barcelona test.
Mercedes has encountered a turbulent start to Formula 1's winter testing in Bahrain, with the team's Trackside Engineering Director Andrew Shovlin admitting they are "still learning how the W17 behaves" after technical problems limited their running across the first two days.
Why it matters:
For a team desperate to return to the front of the grid, preseason testing is a critical period to validate development and build a foundation for the opening races. Significant lost track time and unresolved car balance issues this early can compromise their preparation, potentially handing an immediate advantage to rivals like Red Bull and Ferrari who have enjoyed smoother sessions.
The details:
-
Disrupted Running: The team's program was hampered on both days. George Russell's morning session on Monday was delayed by garage procedural issues, while a suspension problem discovered on Kimi Antonelli's car cost the team several hours of valuable afternoon track time.
-
Performance Concerns: Beyond the mechanical faults, Shovlin highlighted fundamental handling problems. The car suffered from poor balance, leading to brake locking, traction issues, and general inconsistency—a worrying sign for a car's baseline drivability.
-
Contrast with Barcelona: The difficulties in Bahrain stand in stark contrast to what Shovlin described as "near-perfect running" during the earlier shakedown at the Circuit de Barcelona-Catalunya, indicating the issues may be specific to the Sakhir circuit's conditions or later-spec components.
What's next:
With only one full day of testing remaining, Mercedes faces a race against time to diagnose the W17's gremlins and find a stable setup window. The team's ability to quickly learn from these setbacks and implement solutions before the season opener will be the first real test of their 2026 campaign's resilience. Shovlin stated the team is "not short of ideas," but converting those ideas into reliable performance on track is the immediate and pressing challenge.
