Lewis Hamilton was due to jump behind the wheel at Ferrari on Friday but will now miss the day of running.
Lewis Hamilton will not participate in the Pirelli tyre test with Ferrari at Mugello Circuit on Friday, originally scheduled with Charles Leclerc. Pirelli is conducting crucial tests for their 2026 tyre range in Italy. Next year’s tyres will coincide with significant rule changes in F1 for chassis and power unit regulations. Romain Grosjean will make his return to testing since his 2020 Bahrain Grand Prix crash, alongside Ferrari’s Leclerc. Hamilton’s absence is due to being replaced by ex-F1 driver Zhou Guanyu, as he deals with a personal matter regarding his dog Roscoe’s health. Despite missing the test, Hamilton will be back on track for Ferrari at the upcoming Singapore Grand Prix.
