Hamilton and Leclerc test significant upgrades for Ferrari.

      Lewis Hamilton and Charles Leclerc are previewing a significant rear suspension upgrade for their 2025 Ferrari this week. While a 'TPC' test with a two-year-old Ferrari is taking place simultaneously, the Formula 1 pair will be logging the maximum 200 kilometers in the current model at Ferrari's Mugello circuit on Thursday.

      During their 'filming day' activities, Hamilton and Leclerc will provide feedback on the newly designed suspension, which, according to La Gazzetta dello Sport, "involved relocating the attachment point of the upper wishbone." Journalist Paolo Filisetti noted that "this modification is definitely not simple," as it requires ensuring that the specific point on the carbon fibre structure surrounding the gearbox can handle the stresses at the new attachment point.

      Deputy team principal Jerome D’Ambrosio recently mentioned that Ferrari's new addition, Lewis Hamilton, is gradually aligning his setup preferences with Leclerc's in recent races. "A certain balance is necessary to maximize the car's potential," he explained. "Charles has had a car recently that was slightly more inclined to oversteer, which suited him well.

      "Additionally, Lewis has been heading in that direction lately, and it’s benefiting him too." Although the drivers’ and constructors’ world titles are unattainable, Ferrari is focused on maintaining its position ahead of Mercedes and Red Bull for second place overall. A new floor was recently implemented, and the upgraded rear suspension is anticipated to enhance both of these developments.

      "We're improving the car incrementally," Leclerc stated, "but we aren't at a stage where we can feel content yet. However, we are back on track with our development. The introduction of the new floor was a positive step, and the forthcoming parts should bring us closer to McLaren.

      "I don't think we'll catch them," he added, "but we can narrow the gap sufficiently to apply pressure." Hamilton is also feeling more satisfied with his recent experience in the car, but he emphasizes that his main focus is ensuring that the next new car for 2026 incorporates "some of my DNA."

      "I'm gradually acclimating to this Ferrari," remarked the seven-time world champion. "Upcoming new developments give us hope for further progress soon. Charles has established his setup—what works best for the car. I've explored various directions but haven't yet discovered what I’m seeking. So, I want to ensure that I don’t encounter that issue again next year."
