Ferrari’s misjudged development path leaves the SF-25 struggling in 2025
Ferrari’s ambitions for the 2025 Formula 1 season appear to have backfired, as the team’s aggressive development of the SF-25 has reportedly created a series of interconnected technical problems. What was meant to be the car to return the Scuderia to championship contention has instead exposed major design and strategic miscalculations.
Charles Leclerc, now one of Ferrari’s longest-serving drivers, understands better than most how the Maranello outfit approaches in-season development. Heading into this campaign, expectations were high that the SF-25 would finally challenge for the Constructors’ Championship after the team came close to surpassing McLaren last year. Instead, both Charles Leclerc and his new teammate, seven-time World Champion Lewis Hamilton, have found themselves wrestling with a car that struggles to perform consistently across circuits and conditions.
The SF-25 was conceived as a low-riding, aerodynamically efficient car. However, it appears that its design philosophy has clashed with Formula 1’s ride height limitations, leaving Ferrari with a machine that cannot exploit its full aerodynamic potential. The car’s behavior has proven unpredictable, showing flashes of pace on certain tracks but failing to dominate on any specific circuit layout.
While rivals such as Red Bull and Mercedes have managed to seize opportunities to challenge McLaren when conditions allow, Ferrari’s season has been marked by repeated disappointments. The Singapore Grand Prix offered a particularly painful example: despite early promise, both Leclerc and Hamilton endured another frustrating weekend, with reliability concerns overshadowing their efforts. Hamilton’s race ended under difficult circumstances after suffering brake issues in the closing laps — a problem Leclerc later described as symptomatic of Ferrari’s deeper technical troubles.
A development choice that backfired
Reports from La Gazzetta dello Sport have shed light on the root cause of Ferrari’s problems. The publication suggests that Technical Director Loïc Serra made a strategic decision earlier in the season to focus on solving the team’s rear suspension instability rather than pursuing aerodynamic improvements. The decision came after Ferrari’s engineers identified recurring challenges with ride height and vehicle balance — issues that limited the SF-25’s consistency under varying fuel loads and tire conditions.
After nearly three months of intensive work, Ferrari introduced the revised rear suspension at the Belgian Grand Prix. However, what was meant to be a solution may have inadvertently created a new issue: the SF-25 has become significantly less responsive to setup changes throughout race weekends. This has left the team with little room to adapt the car between practice and qualifying, limiting their ability to refine balance and optimize performance.
This limitation contrasts sharply with the approach perfected by Red Bull, whose engineers, led by Adrian Newey before his departure, have mastered the art of gradual performance building across a Grand Prix weekend. While teams like Red Bull and Mercedes often find tenths of a second through setup evolution, Ferrari’s car appears rigid and unreceptive, leaving its drivers unable to close the performance gap once the weekend begins.
Some within Ferrari’s engineering division reportedly believe that even minor improvements in setup flexibility could yield gains of one-tenth per lap — a small but critical advantage that can translate into several grid positions. Yet, by prioritizing mechanical stability over aerodynamic progression, Ferrari may have compromised one of the key tools for weekend optimization.
Ferrari’s update strategy questioned
Insiders have indicated that the decision to allocate extensive resources to the rear suspension redesign effectively halted aerodynamic development for several months. According to the Italian daily newspaper La Gazzetta dello Sport, this trade-off may have cost Ferrari at least two potential aero upgrade packages — updates that could have provided more tangible performance benefits compared to the mechanical rework.
Sources close to the team suggest that both Charles Leclerc and Lewis Hamilton had expressed a preference for aerodynamic improvements, believing that additional downforce and aerodynamic efficiency would deliver more immediate lap time gains. Their perspective, however, appears to have been overruled by technical leadership, which focused instead on addressing the car’s unpredictable rear behavior.
This difference in direction reportedly led to growing internal frustration. Lewis Hamilton, who joined Ferrari this season seeking a fresh challenge after years at Mercedes, is said to have provided detailed feedback to team management outlining how communication and decision-making processes could be improved. His concern, according to reports, was that the drivers’ technical input was being undervalued during critical development phases.
Ferrari’s setup sensitivity now a core weakness
The consequences of these decisions are being felt across every race weekend. The SF-25’s lack of responsiveness to setup changes means that Ferrari’s simulator data and trackside correlation must be perfect to achieve competitive performance — an almost impossible task given the variables of temperature, wind, and tire behavior. When the baseline setup is off, the team finds itself locked into a compromised configuration, unable to extract more speed through typical fine-tuning.
This rigidity has left Ferrari exposed in the development race. While rivals continuously iterate and evolve, Ferrari appears trapped in a narrow performance window. Analysts believe that the SF-25’s rear suspension geometry and weight distribution now limit its aerodynamic adaptability, making upgrades less effective than anticipated.
The long-term concern is that these problems may not be confined to 2025. With the next major regulation change approaching in 2026, any misstep in development philosophy could carry over into the new era of Formula 1. Loïc Serra’s decision to prioritize mechanical revisions over aerodynamic growth is therefore seen by some within the paddock as a gamble that could affect Ferrari’s competitiveness well beyond this season.
Team Principal Frédéric Vasseur now faces the difficult task of guiding Ferrari through the remainder of the season while ensuring that lessons are applied to the design of next year’s car. Trust within the technical department will be crucial, as internal debates over direction and priority continue to shape the Scuderia’s trajectory.
As the Maranello team approaches the winter development phase, the challenge for Ferrari is to balance innovation with pragmatism. Focusing once again on aerodynamic efficiency, improving the car’s sensitivity to setup changes, and aligning development strategy with driver feedback will be key to restoring competitiveness. Failing to do so risks repeating the same mistakes as this season — mistakes that have already undermined what was meant to be Ferrari’s return to the top of Formula 1.
For a team with Ferrari’s legacy, the SF-25 represents a harsh reminder that even the smallest misjudgment in development philosophy can cascade into a season-long struggle. Unless the Scuderia recalibrates its approach, 2026 may begin with Ferrari once again chasing its rivals rather than leading them.
