Although James Vowles and the Williams F1 Team did not participate in the recent Barcelona Shakedown, the team closely monitored the performances of their main rivals in preparation for the 2026 Formula 1 season. Williams had encountered delays passing the FIA crash tests, which prompted Vowles to make the strategic decision to skip the shakedown. The team is now focusing on arriving at the Bahrain pre-season tests fully prepared and ready to maximize track time.
Mercedes impresses as Williams’ engine supplier
James Vowles reported that one of the most notable aspects of the Barcelona tests was the performance of Mercedes, Williams’ engine supplier. The Mercedes-powered teams completed over 500 laps during the five-day session, demonstrating both reliability and consistency. Mercedes’ strong running offered a positive benchmark for Williams as they prepare their own car for 2026.
Ferrari emerged as the second-most active team on track, completing 440 laps. Lewis Hamilton ended the final day of testing with the fastest lap of the week, a 1:16.348, highlighting the potential pace of the SF-26. Mercedes driver Kimi Antonelli also singled out Ferrari as one of the top-performing teams at Montmeló, underscoring the competitiveness of the Scuderia squad as the new season approaches.
Vowles raises questions about Ferrari’s raw speed
Despite Lewis Hamilton’s late demonstration of speed, James Vowles suggested that there are still uncertainties regarding the outright pace of Ferrari’s 2026 car. However, he acknowledged that Ferrari had completed the Barcelona tests without any significant technical issues, which points to a high level of preparation and reliability from the Italian outfit.
For the Williams team boss, the two standout teams in the early testing were Red Bull and Mercedes. Red Bull managed to complete over 600 laps despite debuting an entirely new power unit, a feat made possible by close collaboration with Racing Bulls. Mercedes, meanwhile, faced only minor interruptions caused by red flags from other teams, enabling them to begin race simulations almost immediately. This early ability to run long-distance race programs was seen as a clear indicator of Mercedes’ competitiveness under the new 2026 regulations.
Williams’ perspective on rivals’ performance
James Vowles, speaking at the official launch of the Williams 2026 car, emphasized his admiration for Red Bull’s power unit performance, describing their reliability as remarkable given that it was a completely new engine. He also praised Ferrari’s consistency, noting that while the absolute speed of the SF-26 might remain in question, their ability to deliver stable, uninterrupted running from the start of testing was impressive. James Vowles further highlighted Mercedes’ reputation for technical mastery, particularly when it comes to adapting to regulation changes and producing reliable, well-rounded race packages early in pre-season testing.
Could Williams challenge Ferrari at the start of the 2026 season?
The implications of these observations have fueled speculation about the potential for Williams to challenge the established front-runners in 2026. Former F1 team boss Flavio Briatore has publicly stated that Mercedes possess the strongest power unit under the new regulations, noting that he chose to source engines from Brixworth rather than maintain Alpine’s works program. Vowles expressed a similar degree of confidence in Mercedes’ power units, which are also supplied to world champions McLaren.
If the rumored performance benefits of Mercedes’ new fuel system are as substantial as predicted, Williams could feasibly compete with or even surpass Ferrari and Red Bull in the early rounds of the championship. Success in Bahrain will depend on how much the team lost by skipping Barcelona, but the combination of a solid Mercedes power unit and careful strategic preparation could give the British motorsport engineer and his team an opportunity to upset the established order at the start of the 2026 F1 season.
With Ferrari’s SF-26 demonstrating both speed and reliability, and Lewis Hamilton continuing to push the car to its limits, Williams will have to balance careful development with aggressive race strategy to close the gap. Meanwhile, Charles Leclerc’s performance throughout testing also signals that the Scuderia squad will remain a formidable contender as the season begins in Melbourne.
