Lewis Hamilton and Charles Leclerc Lead Ferrari’s Intensive Pirelli Testing Program
Formula 1’s most anticipated pairing is already putting in the work. Lewis Hamilton and Charles Leclerc are currently spearheading a rigorous series of tests for Pirelli, bridging the gap between technical development and on-track familiarity as Hamilton integrates into the Ferrari ecosystem.
The current focus has shifted to the Fiorano circuit in Italy, where a wet-weather tyre test is underway on April 9 and 10. To simulate challenging race conditions, the track is being artificially soaked, allowing the team and the tyre supplier to gather critical data on wet-weather performance. This isn’t a routine exercise for reserve drivers. Pirelli explicitly requested that Ferrari field its regular Grand Prix drivers.
The rationale is simple: feedback. Hamilton and Leclerc possess the deepest understanding of the car’s dynamics, and their ability to provide precise data is considered essential for the development of the tyres. In a sport where marginal gains dictate the podium, the input of two elite drivers is far more valuable than the laps of a simulator or reserve pilot.
From Rain to Slicks: The Barcelona Outing
Before arriving at Fiorano, the duo was active at the Circuit de Barcelona-Catalunya. That program focused on the development of slick tyres, specifically the C1 through C3 compounds tailored to the demands of the Spanish venue. During those sessions, Hamilton operated a modified 2024-specification SF-24, the same car model that helped Ferrari secure second place in the F1 constructors’ championship.

The Barcelona tests provided a glimpse into the raw pace and workload of the participants. Over the course of the day, 332 laps were completed across the testing fleet. Lando Norris of McLaren led the volume with 159 laps and a best time of 1m 15.21s. Hamilton followed with 87 laps, posting a best lap of 1m 15.93s, although Leclerc completed 86 laps with a best of 1m 16.06s.
For Hamilton, the Barcelona outing was particularly significant as it marked his first opportunity to drive the 2024-spec Ferrari. To push the boundaries of the test, Ferrari reportedly implemented an “extreme” rear wing configuration on Hamilton’s car, testing the limits of the vehicle’s aerodynamics and stability.
Technical Integration and Strategic Timing
These tests are strategically timed to coincide with gaps in the Grand Prix calendar, turning what would be a “mini-vacation” for the drivers into a productive development window. While other teams are also utilizing this time—such as McLaren and Mercedes participating in tests at the Nürburgring—Ferrari is using this period to maximize the synergy between Hamilton and the Scuderia’s technical staff.
The transition for a seven-time world champion is never instantaneous. By splitting running—with Leclerc often taking the morning sessions and Hamilton the afternoon—Ferrari ensures both drivers get quality time with the machinery while maintaining a steady flow of data for Pirelli.
these outings are not just about tyres. They serve as a vital onboarding process for Hamilton, allowing him to feel the balance and characteristics of the Ferrari chassis before the competitive pressures of a race weekend return.
The Road to Monza
The testing schedule does not complete at Fiorano. Ferrari is expected to return to the track later this month for another critical session. A test is already scheduled at the Monza circuit for the end of next week, where the focus will shift from rubber to power. The team plans to utilize the legendary high-speed temple of speed to try out an improved version of the engine.
Between the wet-weather data from Fiorano, the slick tyre benchmarks from Barcelona, and the upcoming power unit evaluations at Monza, Ferrari is leaving very little to chance. For the fans, it is a signal that the Hamilton era at Ferrari is beginning not with a press release, but with a relentless pursuit of technical perfection.
Next Checkpoint: Ferrari returns to the Monza circuit late next week for improved engine testing.
