F1 | Mercedes engine: first setback for Ferrari, but not a decisive one
The Mercedes engine has been at the center of Formula 1 discussions for weeks, especially after suspicions raised by Ferrari and other rival teams. Amid rumors of potential technical advantages and theories about aggressive interpretations of the regulations, the Brackley-built power unit has been firmly under the spotlight. However, pre-season testing also revealed that reliability issues were not entirely absent.
We asked Matteo Bobbi whether, in light of everything that has happened, the Mercedes engine is truly as dominant as some believe, or whether the situation is more nuanced. His response starts from a clear and important point. “First of all, it must be said that it is legal. As of today, it is absolutely compliant because it passes all the tests required by the regulations.”
The current situation of the Mercedes engine after Ferrari’s suspicions
Bobbi highlighted a key moment in the technical calendar. “At the beginning of March, the engines are homologated. After that, they can no longer be modified unless there is a subsequent approved intervention.” This means Mercedes is currently operating fully within the FIA’s rules. But what about performance?
“It is an extremely powerful and efficient engine, especially from an energy management point of view.” In modern Formula 1, where hybrid systems and energy deployment can make a decisive difference over a lap, that aspect is crucial.
Despite its overall strength, the power unit has not been immune to setbacks. “It is not free from problems. If we analyze the six days in Bahrain plus the five in Barcelona, all the teams experienced difficulties. No one was one hundred percent perfect.”
Until a few days ago, it seemed as though Mercedes had avoided technical trouble altogether, but that perception has shifted. “After Barcelona it seemed that Mercedes was free from problems, then they had some. Red Bull had issues, Audi had issues — everyone had them.”
The overall picture that emerges is one of balance and uncertainty ahead of the new Formula 1 season. “No one can go to Melbourne knowing they are completely free from problems. Anyone can run into potential issues.” That reality makes the season opener even more unpredictable.
Still, Mercedes remains one of the reference points on the grid. “According to everyone, Mercedes is one of those teams and one of those power units that start as favorites.”
Powerful, fully legal and widely perceived to have an edge in energy efficiency — yet not untouchable. And in a season shaped by fine margins, even the smallest detail could prove decisive.
The technical standoff between Ferrari and Mercedes shows that the 2026 season will be won as much in the legal office as on the racetrack. While the Mercedes power unit currently holds the upper hand in terms of energy efficiency and raw output, the widespread reliability struggles seen in testing suggest that the pecking order is far from settled. For Ferrari, the “defeat” in the political battle regarding the engine’s legality is tempered by the reality that no team has yet mastered the perfect balance of performance and endurance.
