Ferrari plans engine reconfiguration to counter Mercedes’ top-end power. Ferrari plans to electronically reconfigure their SF-26 engine to reduce Mercedes’ power advantage.

Ferrari technical director Enrico Gualtieri has analyzed the opening two rounds of the 2026 Formula 1 season and believes the team now understands the most effective approach to counter Mercedes’ dominant power unit. The initial races have confirmed that Mercedes and Ferrari are the two leading teams on the grid, with performance margins incredibly tight.

In Australia, George Russell secured victory for Mercedes, followed by Andrea Kimi Antonelli winning the Chinese Grand Prix. Despite strong performances from Lewis Hamilton and Charles Leclerc, Ferrari drivers have consistently finished third and fourth, highlighting both the progress of the Scuderia and the challenges that remain against the Silver Arrows.

Ferrari’s 2026 power unit was designed with a smaller turbo to optimize race starts, and the team has actively lobbied against regulatory changes that could undermine this advantage. Even so, both Lewis Hamilton and Charles Leclerc have managed to lead races temporarily, only to struggle against Mercedes once the opening laps settle into rhythm, particularly during high-speed sections and battery-assisted acceleration zones.

Electronically reconfiguring Ferrari’s engine to fight Mercedes

According to Motorsport Italia, Ferrari is preparing a significant update to their SF-26 power unit. Thanks to the FIA’s ADUO rules, Ferrari is permitted to upgrade their engine after the first quarter of the season, as their current unit is considered slightly weaker than Mercedes’—by more than 2%. This provides an opportunity to address the deficits in energy management and top-end performance.

Gualtieri’s team plans to “electronically reconfigure” the engine to reduce the advantage Mercedes gains from super-clipping—a phenomenon that allows the Silver Arrows to maintain higher speeds at the end of long straights. Battery recharge rates have become a focal point of the 2026 season, as Mercedes currently generate more electric energy per lap, enabling better energy deployment for defending and overtaking.

Additionally, Mercedes’ W17 suffers less top-speed drop-off at the end of straights compared to other cars, giving George Russell and Andrea Kimi Antonelli a notable edge. Ferrari engineers are carefully examining the torque curve of their power unit, as excess energy during acceleration can cause rear-wheel spin, increasing tyre wear and reducing overall efficiency.

Ferrari’s objectives with the reconfiguration are twofold: to save energy by optimizing the hybrid power deployment and to improve tyre longevity, allowing Lewis Hamilton and Charles Leclerc to maximize performance across race distances. While the SF-26 already boasts superior traction, the fine margins this season mean that even minor gains could prevent Mercedes from establishing an unassailable lead.

Lessons from the Chinese Grand Prix and driver performance

At the Chinese Grand Prix, Lewis Hamilton and Charles Leclerc demonstrated their racecraft, even though neither could challenge Andrea Kimi Antonelli for the win. Their on-track battle was thrilling, and Charles Leclerc reportedly expressed enjoyment over the competitive exchange, despite ultimately losing out to Lewis Hamilton’s strategy and pace.

Commentator David Croft has noted that Lewis Hamilton was able to overtake without relying heavily on battery boosts, indicating that the current 2026 regulations may be less dependent on hybrid deployment than initially assumed. This insight reinforces Ferrari’s belief that optimizing energy management and mechanical grip, combined with electronic engine updates, can produce tangible performance improvements.

Looking ahead: Macarena wing and potential victory

Ferrari also plans to deploy their new Macarena wing at the Japanese Grand Prix in Suzuka. Data from the Shanghai Grand Prix suggests that this aerodynamic upgrade could provide meaningful gains in downforce and stability, further aiding Lewis Hamilton and Charles Leclerc in their quest to challenge Mercedes. With these upgrades and the electronic engine reconfiguration, Ferrari is optimistic that a first victory since the 2024 Mexico City Grand Prix may be within reach, marking a significant milestone in the opening season of the 2026 regulations.
