Formula 1's 'big four' teams - Ferrari, McLaren, Mercedes, and Red Bull - appear closely matched after two Bahrain test events, with Ferrari setting the fastest lap time. The teams maintained their traditional dominance despite new regulations and power units for 2026, disappointing outsiders hoping for a competitive shake-up.

Charles Leclerc delivered statement laps for Ferrari on the final afternoon, but longer race simulations showed the top four teams were tightly bunched. Mercedes remains a wildcard, with paddock speculation suggesting they could elevate their performance for the Australian Grand Prix. McLaren's Andrea Stella believes Mercedes and Ferrari hold a slight edge over his team and Red Bull.

Lewis Hamilton's preparation suffered setbacks with technical issues limiting his track time during the final Bahrain test. The seven-time champion completed 71 fewer laps than teammate Leclerc, raising concerns about his readiness for the season opener. With Hamilton seeking redemption after a difficult first season with Ferrari, these reliability problems could prove costly as the championship battle begins in Melbourne.
