Toto Wolff reveals FIA president backs Mercedes in engine controversy
Mercedes F1 team principal Toto Wolff has stated that he has a strong ally in the FIA president amid the ongoing engine controversy.
The controversy revolves around Mercedes’ engine trick involving the compression ratio, allowing for a power increase when the car is in motion compared to when stationary.
Previous regulations only measured the compression ratio under specific conditions, enabling Mercedes to exploit a loophole and potentially gain a significant advantage over competitors.
A recent vote resulted in a rule change to measure the compression ratio at both ambient and operational temperatures from June 1, 2026, with the deadline moved up from August 1.
Wolff emphasized the support of FIA President Ben Sulayem and F1 CEO Domenicali in navigating these issues and addressing them fairly and transparently.
Despite the changes, Wolff remains confident in Mercedes’ standing with the regulatory bodies and officials involved in the decision-making process.
