**Mercedes holds a commanding lead in the 2026 constructors’ championship with 538 points, well ahead of Ferrari, McLaren, and Red Bull, driven by Kimi Antonelli’s eight wins and George Russell’s recent Azerbaijan victory.** The team arrives at Sepang for the rescheduled Bahrain Grand Prix with its first major upgrade package since Canada, featuring floor and rear suspension changes aimed at boosting downforce and race pace. Practice sessions showed mixed signals, with Red Bull’s Max Verstappen and McLaren posting competitive long-run times on the high-degradation, abrasive track under hot, humid conditions, while Mercedes evaluated the new parts amid tyre overheating concerns. Rivals note the field remains tight, but Mercedes’ overall form, power unit strength, and upgrade give traders the strongest consensus for their constructor to deliver the race winner or first points scorer. Backmarkers like Cadillac remain far behind in development and standings.
