How Ferrari’s hidden developments helped Lewis Hamilton deliver a landmark victory. How Lewis Hamilton and Ferrari engineered a historic first victory in Barcelona.

The first victory of Lewis Hamilton’s Ferrari career could hardly have been achieved in a more Hamilton-like fashion. It was a triumph aided by circumstance, although perhaps luck was not even necessary. What truly allowed Lewis Hamilton and Ferrari to write a new chapter in Formula 1 history was flawless execution, both strategically and behind the wheel. The achievement was also the result of extensive work back at Maranello, where engineers developed upgrades that largely went unnoticed by the public but proved crucial to the outcome.

The lap that shaped the strategy

Ferrari’s winning weekend effectively began on Saturday morning. Before qualifying, the team made significant setup changes to the SF-26 after struggling during practice sessions. Those adjustments helped Lewis Hamilton rediscover the confidence and connection with the car that were essential to securing a front-row starting position and putting himself in contention for victory.

Interestingly, the foundations of the win were not laid at the start of the race, where Ferrari’s rivals demonstrated that they had largely closed the performance gap. Ferrari was even the only front-running team to begin the Grand Prix on the soft tyre compound, a decision that ultimately proved to be the correct one.

Leading the field, George Russell initially controlled the pace, perhaps anticipating a two-stop race strategy. That approach allowed Lewis Hamilton to remain within striking distance despite running on used soft tyres. Ferrari’s first pit stop caught Mercedes off guard, forcing an immediate reaction from the Silver Arrows on the following lap. However, the delay cost Mercedes more than a second. Even then, Lewis Hamilton maintained impressive pace, staying close enough to George Russell to create another opportunity during the next round of pit stops.

The decisive moment came during the second pit-stop phase. Benefiting from a fresh set of medium tyres that Ferrari had preserved at the start, Lewis Hamilton gained 2.4 seconds on George Russell in just the final two sectors of his out-lap. The advantage was simply too large for Mercedes to cover.

That performance allowed the Ferrari driver to break free from George Russell’s strategy and build a gap, which later enabled him to take advantage of the Virtual Safety Car for his final stop. It is difficult to know whether Lewis Hamilton would have been able to pass Lando Norris and the two Mercedes cars on track without the neutralisation, but that uncertainty does not diminish a day that showcased the very best version of the seven-time world champion.

Lewis Hamilton’s adaptation process

Winning a Grand Prix with Ferrari marks the culmination of a long and demanding adaptation process for Lewis Hamilton. The British driver initially struggled to adjust to the many differences within the Scuderia, including a power unit with completely different drivability characteristics, vibration levels and engine-braking behaviour compared to the Mercedes engines he had used throughout his Formula 1 career.

Rather than becoming discouraged, Lewis Hamilton focused on understanding how to adapt to Ferrari while simultaneously helping Ferrari adapt to his preferences. One example was his switch to Carbon Industrie brake discs from the Japanese Grand Prix onward. Those components provided the more progressive braking feel he prefers, in contrast to the sharper response of the Brembo system.

Another important factor was the arrival of Carlo Santi as his race engineer, whom Lewis Hamilton jokingly described as his “Italian Bono.”

Between the two, chemistry developed immediately, allowing Hamilton’s feedback to be translated more effectively into engineering targets. This collaboration also helped Ferrari introduce a new setup philosophy beginning with the Canadian Grand Prix, a change that has already produced two second-place finishes and now a historic victory.

The hidden evolution of the SF-26

Ferrari itself deserves enormous credit for the success in Barcelona. The team’s extensive upgrade package included revisions to the floor, front wing and sidepods, allowing the SF-26 to take a significant step forward.

The Scuderia moved ahead of several rivals, many of whom arrived in Spain without major upgrades but are expected to respond soon.

“They will probably bring something to Silverstone or elsewhere, but we will also bring something soon,” said Fred Vasseur.

For Ferrari, the encouraging news is that the upgrades introduced so far have worked exactly as intended. More importantly, the team’s development concept still appears to offer considerable room for improvement in a championship that is increasingly becoming a battle of development rather than pure aerodynamic performance. At both Monaco and Barcelona, Ferrari also introduced subtle wheel-rim modifications designed to improve tyre cooling and tyre degradation management. Those changes remained largely hidden from public view but played a significant role in helping the SF-26 excel in the extreme temperatures experienced during the Spanish Grand Prix.

Ferrari is now awaiting further power-unit developments, although talk of a championship comeback remains off limits within the team: “This is the worst possible approach. The correct approach is to go to Austria with exactly the same mentality we had in Barcelona,” Fred Vasseur reminded everyone.

Motivation is certainly not lacking, and restoring Charles Leclerc’s confidence will be another key objective. The Monegasque driver insists he feels comfortable with the SF-26, and if he can mentally reset after a difficult run of mistakes stretching back to Miami, he could soon find himself back in the fight for victories.

Kimi Antonelli’s psychological victory

Mercedes left Barcelona as the defeated team despite showing the pace needed to challenge for a seventh consecutive victory. The W17 failed to deliver the advantage many expected in a race that should have highlighted Mercedes’ renowned tyre-management strengths.

“Mercedes are very strong at managing temperatures in hot conditions. We have seen that in the data,” confirmed Pirelli Chief Engineer Simone Berra.

Perhaps it is only a matter of time before Mercedes’ next round of upgrades restores the W17’s superiority.

Even without winning, however, the standout Mercedes driver was once again Kimi Antonelli. After a relatively quiet qualifying session and opening phase of the race, the Italian produced an exceptional second stint, consistently gaining several tenths of a second per lap on George Russell.

Once Kimi Antonelli closed in on his teammate during the final stint, Mercedes informed George Russell over the radio that Antonelli was faster. The message immediately appeared to increase the pressure on the British driver.

George Russell attempted to respond by lowering his lap times by roughly four tenths for two consecutive laps, but in doing so he placed excessive stress on his tyres. The consequences arrived quickly. Kimi Antonelli, by contrast, remained calm and continued producing remarkably consistent lap times before completing a psychologically significant overtake.

Unfortunately for the Italian, he was then betrayed by a battery-related issue. The component has caused repeated reliability problems across both the factory Mercedes team and its customer outfits, although the failures have varied in nature from case to case.

Back in Monaco, Andrea Stella accepted responsibility for McLaren’s power-unit and chassis integration challenges, but the reliability of the Brixworth-built Mercedes power units is becoming an increasingly serious concern throughout the paddock.

McLaren still leads the chasing pack

Kimi Antonelli’s retirement opened the door for Lando Norris to secure a podium finish. McLaren displayed impressive race pace in Barcelona, once again confirming its excellent tyre management characteristics.

Even so, the MCL40 still appears to have ground to make up compared to the benchmark teams. The same can be said for Red Bull, which found itself isolated in fourth place with Max Verstappen.

Perhaps it is no coincidence that the two teams that battled for the championship last season are now paying the price for continuing development of their 2025 cars for longer than their rivals. Ferrari, by contrast, followed a similar path to Mercedes by shifting resources to the 2026 project earlier.

That decision has already delivered one historic reward: Lewis Hamilton’s first Formula 1 victory in Ferrari red.
