Toto Wolff, the team principal of Mercedes, has called on the FIA to ensure that the new engine development rules for the 2026 season do not interfere with the current competitive order in Formula 1. The rules, which include three periods of Additional Development and Upgrade Opportunities (ADUO), are designed to allow power unit manufacturers that are lagging behind to catch up with the leaders.
However, Wolff has urged the FIA to implement these rules with precision, clarity, and transparency to prevent any team from gaining an unfair advantage. With Mercedes currently leading the championship, Wolff's comments have sparked interest, particularly as his team's self-manufactured engine is likely to be the benchmark for other teams to catch up with. The FIA is expected to provide more clarity on the implementation of the rules ahead of the Miami Grand Prix.
