Wolff Tells Rivals to Focus After Engine Legality Row

Wolff Fires Back Amid Engine Regulation Controversy

Mercedes Team Principal Toto Wolff has issued a blistering rebuke to rival Formula 1 teams, dismissing accusations surrounding the legality of Mercedes' new power unit and urging competitors to focus on their own performance.

The controversy centers on technical regulations for 2025, specifically the mandated reduction of the compression ratio from 18:1 to 16:1. This ratio measures cylinder volume and is officially checked under ambient pit-lane conditions. Rivals have raised concerns that Mercedes may have developed a method to effectively run a higher ratio on track, potentially yielding a significant performance advantage.

"Get your shit together," Wolff declared to media, including RacingNews365. He expressed frustration with teams he alleges are more focused on challenging Mercedes than improving their own projects. "They are just doing secret meetings and sending secret letters and keep trying to invent ways of testing that just don't exist."

Wolff stated that the FIA has repeatedly affirmed the legality of the Mercedes power unit. "Communication with the FIA was very positive all along... It's very clear what the regulations say, it’s very clear what the standard procedures are."

He positioned the criticism as a distraction tactic by rivals preparing excuses for potential performance shortfalls. "Maybe you want to find excuses before you’ve even started when things are not good. That is not how we would do things, especially when you’ve been told enough times that it’s fine."

Mercedes Asserts Confidence and Legality

With pre-season testing in Bahrain on the horizon, Wolff was unequivocal about the status of the engine. "The power unit is legal," he asserted. "The power unit corresponds to how the regulations are written... and that's what the FIA said."

The team arrives at the test buoyed by a productive shakedown in Barcelona, where they completed over 500 laps. Wolff summarized the team's stance as "robust," signaling confidence as the season approaches.

The coming test will begin to reveal whether Mercedes' technical interpretation provides the competitive edge its rivals fear, or if the off-track arguments will fade once the cars hit the track.
