The FIA has confirmed that a vote on a proposed change to the assessment of the power unit compression ratio in running condition will take place
The FIA has confirmed that F1 engine manufacturers will vote on a proposed change in how engine compression ratios are measured. If approved, the change could be implemented as early as the summer break in August this year. Mercedes has been under scrutiny for allegedly exploiting a loophole in the 2026 engine regulations, leading to disputes with rival teams. The controversy stems from concerns that some manufacturers may have found a way to exceed the specified compression ratios in the new regulations. A recent meeting involving the PUAC and the five engine manufacturers – Mercedes, Honda, Red Bull Powertrains, Ferrari, and Audi – resulted in a proposal to measure compression ratios under both ambient and operating conditions. The outcome of the vote on this proposal is expected within the next 10 days and will be subject to final approval by the FIA World Motor Sport Council.
