The most unusual element came at the end of FP1, when the FIA conducted a low grip mode simulation with all the cars. This test was part of the governing body's ongoing response to the incidents witnessed at Sepang earlier this season. According to an FIA statement, the focus was on refining power unit software protections, with teams and manufacturers working together to validate new safety measures. Drivers ran specific in-lap inputs while operating in low grip mode at low speeds through Turn 15 to test additional software safeguards, a procedural step aimed at preventing future safety concerns.
