Toto Wolff, the head of Mercedes, has called on the FIA to ensure that the new regulations allowing power unit manufacturers to upgrade their engines during the 2026 season do not interfere with the current competitive order in Formula 1. The regulations include a performance-balancing measure that enables manufacturers trailing the leader by a certain margin to develop their engines. The FIA is expected to provide more clarity on the rules ahead of the Miami Grand Prix.
Wolff emphasized that the rules should be implemented with precision, clarity, and transparency to prevent any team from gaining an unfair advantage. He noted that the current pecking order should not be disrupted, and any decisions made by the FIA should prioritize the integrity of the sport.
With Mercedes dominating the early stages of the season, their engine is likely to be the benchmark for other teams to catch up with. However, Wolff suggested that only one engine manufacturer, Honda, needs assistance. He expressed concern that granting upgrades to certain teams could interfere with the competitive balance, but stated that he trusts the FIA to make decisions that protect the integrity of the sport.
