F1 engine manufacturers have been given the chance to vote on a key and controversial element of the new regulations.
Formula 1 engine manufacturers have recently voted on a crucial and controversial element of the new regulations regarding the measuring of power units’ temperatures at a fixed compression ratio of 16:1 in ambient conditions.
Mercedes and Red Bull initially exploited a perceived loophole in the regulations, causing a stir and leading to demands for increased clarity and fairness from the other manufacturers – Audi, Ferrari, and Honda.
Meetings between the manufacturers and the FIA have ensued, with Red Bull aligning with the discontented manufacturers, leaving Mercedes isolated in their stance.
A recent meeting has concluded that a vote will determine whether the compression ratio measurements will be revised to include both ambient and operational temperatures, potentially affecting the performance advantage of the existing power units.
The vote outcome is expected within the next 10 days, with the potential for a change in landscape for Mercedes’ power units and their rivals for the remaining races of the 2026 season, starting with the Dutch Grand Prix in August.
The FIA’s proposal could lead to a significant shift in the competitive balance in Formula 1 for the second half of the season, pending the vote’s result and subsequent approval by the World Motor Sport Council.
