One reason is apparently the switch to E10 petrol. Since 2022, ten percent of the fuel must be CO2-neutral. Before it was only about half. Starting up the sustainable portion costs around 20 hp per se and required adjustments to the combustion chambers, which Ferrari and Red Bull-Honda are said to have managed better than Mercedes.
Insiders speculate that ex-engine boss Andy Cowell is missing. The father of the hybrid monster left the Mercedes engine workshop in Brixworth in mid-2020. Other top technicians have migrated to Red Bull in 2021, including Ben Hodgkinson, who worked at Mercedes as chief engine mechanic.
Mercedes team boss Wolff does not want to put the engine at the center of criticism. “It’s important not to point your finger at individual areas of the car. We operate as a team and we have deficits that are far greater than just an engine deficit. Are we among the top teams in any of these areas? I do not believe that. But you have to remember that this engine helped us win the Constructors’ Championship eight times in a row.”
Alone: whining doesn’t help. “Now we all have to pull together and pull ourselves out of this mess. We won’t let up until we’re back on top. This is an exercise in humility and it will make us stronger.”
What can become the biggest problem for Mercedes: The power units were frozen before the start of the season until the end of 2025 for cost reasons. This means that further developments for performance purposes are prohibited. Mercedes has to find top speed somewhere else.
