McLaren F1 team principal Andrea Stella conceded Mercedes and Ferrari demonstrated superior pace during race simulations at the inaugural pre-season test in Bahrain. Stella explicitly stated the Italian and German manufacturers were 'quicker than us' during the intensive long-run sessions on Thursday and Friday. While the exact pecking order remains fluid, Red Bull Racing also appears positioned to challenge for the top spot, according to Stella's assessment. This early verdict from the team principal highlights the significant competitive gap McLaren faces entering the 2026 season, which will feature major regulatory changes including new power units and aerodynamic rules.
