At the heart of the storm lies the technical detail of compression ratios in Formula 1’s new power unit regulations. While the rulebook caps compression at 16:1, speculation suggests Mercedes engineers may be leveraging thermal expansion to briefly push performance closer to 18:1 under race
James Vowles strongly criticized rival teams, including Cadillac and Sergio Pérez, who are complaining about the new Mercedes power unit that Carlos Sainz will be using.
According to the Williams executive, the engine complies with all regulations and it is unfair for competitors to try to make up for their shortcomings by adjusting the rules.
The director defended the importance of maintaining fair competition, as he told Motorsport.com: "I am convinced that the power unit we use complies perfectly with the regulations. It's not a matter of achieving this in a month, but of years of work to reach that level.
"It's understandable that rivals are frustrated because they haven't achieved what Mercedes has, but we must act cautiously. At the moment, no one can say which is the best engine, as we are focusing on a single detail," Vowles concluded.
This controversy has sparked tensions in the paddock ahead of the new era of Formula One. At the heart of the conflict lie the technical specifications of the engines to be used from this year onwards.
Although the regulations set a maximum compression ratio of 16:1, Mercedes is suspected to have found a way to increase it to 18:1 during the race, exploiting the thermal expansion of certain components to deliver more power than its rivals.
Vowles stressed that motorsport must remain a meritocracy where technical innovation is rewarded. During the Bahrain Grand Prix, he warned that Formula 1 should not drift into a championship based on Balance of Performance, a method used mainly in GT3 categories to artificially equalize performance.
