The final day of the Bahrain F1 pre-season testing saw Mercedes showcasing impressive performance, with Kimi Antonelli and George Russell leading the timesheets. Antonelli set the fastest lap, while Russell also recorded quick times, helping the team to a one-two finish. However, the day was not without challenges as Lewis Hamilton experienced a breakdown that brought out the red flag. Throughout the testing, rivals like Ferrari and McLaren have shown strength, while Red Bull faced technical issues. As teams continue to refine their cars before the season, the competitive landscape appears uncertain with all teams pushing to stay at the front.
