Principal of the Mercedes Formula 1 Team, Toto Wolff, suspects that certain teams in the paddock may be at a disadvantage when it comes to developing the 2026 engine. The upcoming power units will introduce 100% sustainable fuels, eliminate the MGU-H system, and rely more on electrification. This means that the new power units will have an equal power split between the internal combustion engine and electric components. Wolff believes that some teams will fare better than others in terms of developing the 2026 power unit, leading to requests for regulation revisions in light of the preliminary chassis and aerodynamics regulations.
According to Wolff, the ship has already sailed when it comes to the power unit side. Some teams feel they are at a disadvantage, while others, including OEMs, believe they have done a good job. This is a normal part of the struggle with regulations. On the chassis side, there may be some possible adjustments that need to be made, but the engine side is very advanced in the process.
The regulations for the 2026 power unit were finalized in 2022, and the preliminary chassis and aerodynamics regulations were announced prior to the Canadian Grand Prix. Critics of the chassis and aerodynamics regulations believe compromises are being made due to the changes in the power unit. The Principal of the McLaren Team, Andrea Stella, believes that adjustments need to be made in how the power units are planned to be used. In response, the FIA’s Seat Director, Nikolas Tombazis, is confident that a discussion among engine manufacturers can take place regarding the 2026 power units. He believes there is a good spirit of collaboration and that if adjustments are necessary, the UP manufacturers would be willing to help.
Despite this, Wolff’s comments suggest otherwise. It is not surprising considering Mercedes’ dominance in the hybrid era since 2014. There is a sense that a similar event could occur in 2026. Mercedes driver George Russell has expressed confidence in the team’s engine for this era, stating that they are in a great position to have a strong engine. With Mercedes’ recent difficulties in winning GPs, it is understandable why the team wants to maintain any advantage they believe they have for 2026 and beyond.
