- Lewis Hamilton has called for a serious investigation by the FIA into Mercedes' alleged use of an illegal engine trick.
- Toto Wolff has denied any wrongdoing regarding the power unit's performance enhancements.
- Hamilton expressed concerns about performance disparities and the need for a level playing field among teams.
Mercedes has stolen the spotlight since the beginning of the 2026 season. The team allegedly figured out a borderline illegal trick with the compression ratio in the power units. Amid the investigation by the FIA into the matter, Lewis Hamilton has demanded that the matter be looked into more seriously.
Toto Wolff had formally denied claims of using any tricks in the Mercedes power unit that provided them with an additional boost. Even McLaren firmly believed that the German carmaker was not using any illicit tricks and was fully within the legal parameters of the power unit regulations. Now, Mercedes’ most successful driver provides his opinion on the matter and how Brackley must be investigated.
Following his outing at the pre-season testing in Bahrain, Lewis Hamilton had some worrying concerns about performance under the new regulations. Hamilton reckoned that he wasn’t aware of the fuel loads that the teams were running during the first testing session. Further, the Briton talked about some whispers in the community about Mercedes gaining extra power because of the compression ratio.
Now, Lewis Hamilton is hoping that the issue gets sorted and Mercedes receives the green light from the FIA. Moreover, the governing body needed to ensure that all teams were starting the season on a level playing field and no one had any extra advantage over the rivals. For now, Brackley and the customer teams are not concerned with the allegations and are looking forward to the challenge at the Australian GP.
We don’t know what fuel loads people are on. There are whispers of certain fuel loads that Mercedes are on. There are whispers of extra power they have that the rest of us don’t — the compression ratio sort of thing. So hopefully that gets sorted. And the FIA take care of that and make sure we’re all starting on an even playing field.
Lewis Hamilton said, as reported by motorsport.com.
Lewis Hamilton reveals 2026 F1 challengers ‘don’t feel great’
The challengers of the new regulations will focus more on the electrical part of the power units and work more on the active aerodynamics. Lewis Hamilton, who suffered from a nightmare of a debut with Ferrari in the 2025 season, will look for redemption in the upcoming season. However, his season might not be off to a great start, as he had some concerning comments about the challengers.

Lewis Hamilton asserted that driving the 2026 F1 challengers was like driving in Monza and having high downforce everywhere. As such, the car was sliding a lot and ultimately did not feel great to drive around in. Further, Hamilton claimed that the uncertain wind conditions around the track made the driving experience different on different corners of the track.
Basically, it’s like Monza downforce everywhere. So you’re sliding around on the top of the tyres, so it doesn’t feel particularly great, In some corners it feels good. And because of the wind, some corners feel good because you’ve got a headwind — but most of the others you’ve got either tailwind or crosswind, and it’s a moving goalpost. I think everyone’s in the same boat.
Lewis Hamilton noted.
The first race of the 2026 season is less than a month away. Ferrari has shown up with decent enough results, but could face a stiff challenge against the likes of Mercedes and Red Bull. For now, initial feelings are positive for the team. Time will tell how Lewis Hamilton performs on track and if he can be good enough to contend for his record-breaking eighth championship win with the Italian constructor.
