What happened: Mercedes rolled out a special livery for the Bahrain Grand Prix weekend at Sepang, where Formula 1 shifted round 16 after Bahrain's cancellation. The team also arrived with a new floor and reworked sidepods as part of a seven-piece upgrade package.

Why it matters: The change lands in the middle of a triple-header, leaving little time to separate presentation from performance once running begins. Mercedes has led the 2026 field under intermittent pressure, so any gain from the Sepang package could matter immediately over the rest of the weekend.

What to watch: Practice and qualifying will show whether the revised package changes Mercedes' one-lap pace and tire behavior at Sepang. Longer race runs should offer the clearest read on whether the update delivered more than a cosmetic shift.
