Ferrari’s Bold Move: Can New SF25 Upgrades Challenge McLaren’s Dominance in F1?

As the Formula 1 season heats up, Ferrari finds itself in the spotlight once again with a dramatic and unexpected development. A leak from Maranello has revealed that Lewis Hamilton has been secretly testing a component that could significantly affect the 2025 season, with the Belgian Grand Prix being the stage where the world will witness the potential impact of these upgrades. The key question on everyone’s mind is whether the major upgrades to the SF25 will be enough to challenge McLaren’s current dominance. Let’s dive into the details and explore whether Ferrari’s gamble will pay off.

Ferrari’s Early Season Struggles

From the very beginning of the 2025 season, Ferrari’s performance has been marked by inconsistency. The SF25, while blisteringly fast in qualifying sessions, has struggled to maintain that pace during the races. The root cause of this issue is the car’s rear suspension, which has proven to be a significant Achilles’ heel.

Ferrari’s engineers took a bold approach in the SF25’s design, opting for a radical shift in weight distribution. The cockpit was moved rearward, leading to the repositioning of the engine and fuel tank as well. While this aggressive move was aimed at improving the car’s balance and performance, it came with unintended consequences. The gearbox space was reduced, and the car’s pull-rod rear suspension proved to be a compromise that ultimately led to instability.

The Suspension Woes and Their Impact

The rear suspension’s issues became glaringly apparent, especially when the car hit high speeds at the end of straights or entered heavy braking zones. Ferrari was forced to use rear dampers that couldn’t fully control the car’s vertical movements. This instability had more than just a superficial effect—it disrupted the car’s aerodynamics, particularly its ground effect, which is crucial under current F1 regulations.

Ground effect relies on a smooth flow of air underneath the car to create downforce, and any oscillations or disruptions in the car’s height above the track surface can significantly impact this. When suspension oscillations disrupt this airflow, it leads to a phenomenon known as “porpoising.” This issue causes the car to bounce up and down uncontrollably, creating unpredictable driving behavior and excessive tire wear. In addition to the handling problems, it accelerates tire degradation and can even damage the car’s undercarriage.

To manage these issues, Ferrari was forced to set the car into what is known as “Leo mode,” a more conservative setup that reduces vertical stress but also significantly sacrifices aerodynamic efficiency. This costs Ferrari as much as 0.3 seconds per lap, a steep price to pay just to keep the car intact.

Ferrari’s Strategic Response

Despite these challenges, Ferrari’s engineers were quick to act, developing a bold solution to address the rear suspension problems. They designed a modification to the rear suspension structure aimed at increasing the antilift effect on the upper wishbone. This change was intended to keep the rear of the car low during braking, providing more stability when entering corners and maximizing ground effect.

However, rather than announcing these changes publicly, Ferrari chose to test them in secrecy. At the Mubell circuit, they held a private 200 km test, which was disguised as a filming day. During this test, both Lewis Hamilton and Charles Leclerc were tasked with testing the new suspension prototype. Alongside them were two key figures from Ferrari—team principal Fred Vasseur and chief car performance architect Laurent Ménié—who closely monitored the data to evaluate the success of the upgrades.

Mixed Reactions: Hamilton Optimistic, Leclerc Cautious

The test results were mixed. Lewis Hamilton, always a keen and experienced tester, responded positively to the new suspension setup. He provided detailed feedback, particularly focusing on the car’s behavior under braking and mid-corner stability. His experience in handling such challenges was crucial, and he seemed convinced that the upgrades were moving the SF25 in the right direction.

Charles Leclerc, on the other hand, was less enthusiastic. While he acknowledged some improvements, he reportedly wasn’t as convinced by the changes, and his feedback suggested that the adjustments were not as revolutionary as Ferrari had hoped. His cautious approach indicated that there was still much work to be done before Ferrari could challenge the top teams consistently.

An anonymous source from Motorsport Italia stated that this new suspension setup is far from the groundbreaking innovation that Mercedes introduced a few seasons ago. Instead, it seems more like a stepping stone—a significant but not revolutionary improvement.

Silverstone and Optimism

Before the Belgian Grand Prix, Ferrari had experienced a small glimmer of hope at Silverstone. A series of upgrades to the car’s floor helped mitigate the SF25’s sensitivity to ride height. The adjustments made the car more forgiving, allowing Ferrari to perform well in qualifying and stay competitive with McLaren during several stints of the race. However, these upgrades weren’t a magic bullet. F1 analyst Matteo Bobby emphasized that while the SF25 showed potential, it was not a revolutionary leap. It was, however, an important step toward achieving more stable aerodynamics.

In addition to the suspension improvements, Ferrari also faced challenges related to fuel distribution problems, particularly when the tank was nearly empty. These issues became evident at Silverstone and showed that, despite some progress, the SF25 still has several unresolved problems.

Spa: The Crucial Test

All eyes now turn to the Belgian Grand Prix at the iconic Spa-Francorchamps circuit. This race will be more than just another weekend—it is a crucial test for Ferrari’s progress. Spa, with its fast and unforgiving corners like Eau Rouge, Radillon, and Blanchimont, will provide the ultimate proving ground for the SF25’s new suspension.

If the new components perform as expected, Ferrari will be in a strong position to challenge McLaren for the front-running positions once again. However, if the improvements fail to produce tangible results, it could signal the beginning of a shift in focus towards the 2026 car project. With major regulatory changes coming for the 2026 season, Ferrari cannot afford to waste too much time on a car that is no longer competitive.

Hamilton, Leclerc, and the Fight for the Title

Lewis Hamilton, at 40 years old, is still a formidable force in Formula 1. His desire to win an eighth world title burns as strongly as ever, but with only a few seasons left in his career, time is running out. This season could be his last real opportunity to fight for that elusive eighth title before the major shake-up of the 2026 regulations.

On the other hand, Charles Leclerc has a different set of challenges. While he is one of the fastest drivers on the grid, this season represents a pivotal moment in his career. If he is to become a world champion, he must prove himself not only in terms of raw speed but also as a mature leader capable of guiding Ferrari back to the top.

McLaren’s Unstoppable Momentum

Meanwhile, McLaren has emerged as the team to beat in 2025. Their consistency, pace, and near-perfect execution have made them the clear frontrunners for this season’s title. McLaren’s dominance is formidable, and for Ferrari, the road to closing the gap looks steep. To realistically challenge McLaren, Ferrari needs more than just performance upgrades—they need a combination of strategic luck and flawless execution over the next few races.

The Road Ahead

As Ferrari prepares for the Belgian Grand Prix, the hope is that the new suspension upgrades will cut lap times by up to 0.3 seconds, enough to get them back into podium contention. This is vital if they want to stay in the fight for both the Constructors’ and Drivers’ Championships. But the real question is whether these upgrades will mark the beginning of Ferrari’s revival or if Spa will reveal the truth: Ferrari is still a step behind. All will be revealed at Spa, and it is here that the future of Ferrari’s 2025 season will be decided.
