The 2026 Formula 1 season has already started for almost every team, with one exception: Williams. As explained by team principal James Vowles, the Grove-based squad has had to deal with delays linked to the development of its 2026 car. The FW48 did not take part in testing at Barcelona, but it has now been confirmed that the car will appear at the Bahrain tests scheduled for next week.
Mercedes power unit provides reliability confidence
The team has already passed all crash tests, although there were some concerns related to the weight of the chassis. Carlos Sainz even offered his assistance to help Williams navigate what, on the surface, seems to be a challenging situation. A major positive for the team is the certainty provided by their Mercedes power unit. The Brixworth-built engine has already delivered strong reliability results, which removes one key concern for the squad.
The FW48 project pushes boundaries
James Vowles spoke about the reason behind Williams’ delayed start to the 2026 season. The FW48 has not yet hit the track, which puts the team at a disadvantage compared to its rivals. The challenges, he explained, are largely due to the complexity of the new Formula 1 regulations, which forced the team to push the car “beyond the limits” in its design and development.
Despite the setbacks, the team remains focused on solving the technical issues and preparing the FW48 for competitive testing in Bahrain. Passing the crash tests demonstrates that, while ambitious, the project is moving in the right direction. With the Mercedes engine providing a solid foundation, Williams hopes to close the gap to its competitors as soon as the season begins.
In short, the delays are a result of the team pursuing a technically bold approach rather than cutting corners, showing Williams’ determination to maximize the potential of the new car under the 2026 regulations. James Vowles emphasized that, although the FW48 hasn’t run yet, the groundwork laid now could pay dividends once testing starts in Bahrain.
