F1 returns to Sepang: Pirelli tyres, heat and rain create major unknowns

Formula 1 is returning to the Sepang circuit in Malaysia after a nine-year absence, presenting teams with significant tyre, weather, and setup challenges. Because the sport last visited the circuit in 2017, competitors possess no directly comparable data for the current generation of machinery and tyres.

Pirelli has chosen the C2, C3, and C4 compounds for the event to open strategic options. Teams must manage high thermal degradation, high track abrasiveness, intense heat, humidity, and the risk of tropical rain.
