FIA confirms Red Bull's engine remains most powerful in F1
The FIA's latest rankings show Red Bull still have the most powerful internal combustion engine in Formula 1. The governing body's Aduo programme measures only the engine's power, not electrical elements. Mercedes are allowed one upgrade in 2026 and 2027, while others get two.
The FIA’s Aduo programme, introduced alongside the new hybrid engine rules, ranks internal combustion engine power only, excluding electrical output that contributes nearly half of total performance. Red Bull’s engine was again rated best, while Mercedes fell into a 2–4% deficit window, and Audi, Ferrari, and Honda exceeded 4%. These findings, updated every six races, determine how many upgrade opportunities each manufacturer receives in 2026 and 2027. Mercedes gets one per year, others two, and Red Bull none. The decision follows a similar result three months ago, disappointing Red Bull, who have yet to win a race this season while Mercedes has claimed eight victories.
This ranking could shape competitive balance in Formula 1 over the next two seasons, influencing which teams can close performance gaps. Fans may see closer racing if trailing manufacturers use their extra upgrades effectively, while Red Bull’s lack of allowances might prolong their current struggles. The exclusion of electrical power from the measurement could spark debate about fairness, potentially affecting sponsor interest and viewer engagement as teams’ fortunes hinge on technical regulations rather than on-track action alone.
