The mounting criticism from top drivers like Max Verstappen and Sergio Pérez toward Formula 1's 2026 technical regulations has pushed the FIA into a reactive stance, with the governing body seeking adjustments to address the most pressing shortcomings of the new ruleset. Changes were implemented ahead of the Miami Grand Prix, but by most accounts in the paddock, they have not gone nearly far enough.

Now, a new set of concerns is emerging — and this time the spotlight is falling on Ferrari. According to information published by Motorsport Japan, the Scuderia could face serious structural headwinds if the planned regulatory changes for the 2027 season remain in their current form.

The report suggested that among the five engine manufacturers currently competing, Mercedes stands to lose the least from the adjustments. While the performance derived from the MGU-K system would be reduced across the board, Mercedes is reportedly operating its internal combustion engine at its highest-ever output — a position that insulates them considerably from the worst of the regulatory impact.

Ferrari's picture, by contrast, is more troubling. The report indicated that the Scuderia's ICE is currently estimated to be running approximately two percent behind Mercedes in terms of peak power output. Under the new regulations, the weaknesses of its smaller turbo configuration are expected to become even more exposed — dragging performance further rather than helping close the gap to the front.

Even if Ferrari receives a partial benefit from any increase in fuel flow allowances, the underlying deficiencies of its turbo design would reportedly continue to weigh it down.

These regulatory concerns serve as a reminder that Formula 1 is as much an engineering arms race as a sporting competition. Not every team builds its own power unit — smaller and mid-field outfits typically source engines, gearboxes, and related components from the major manufacturers, operating under strict FIA guidelines.

Ferrari's performance concerns also arrive against the backdrop of a painful season for Lewis Hamilton. His first year at Maranello in 2025 produced results that were far below any reasonable expectation — results many observers described as humiliating for a seven-time world champion.

If the 2027 regulations deepen the Scuderia's structural disadvantage, that could accelerate conversations about Hamilton's future at the team or even his continued participation in the sport altogether.

The current engine supply breakdown for the 2026 Formula 1 season is as follows:

Mercedes — Mercedes, McLaren, Williams, Alpine 

Ferrari — Ferrari, Haas, Cadillac 

RBPT Ford — Red Bull, Racing Bulls 

Honda — Aston Martin 

Audi — Audi
