What happened: Attention has turned to whether Ferrari can sustain its current rate of car development through the season. The question comes amid pointed commentary from Mercedes, whose leadership has openly doubted that Ferrari's spending on upgrades is sustainable under Formula 1's cost cap.

Why it matters: The cost cap limits how much any team can spend, so a heavy early-season development push can force trade-offs later in the year. If Ferrari is investing aggressively now, it risks slowing its upgrade path in the closing races just as rivals keep pushing. Mercedes' strong championship position sharpens the stakes of that gamble.

What to watch: Watch Ferrari's upgrade cadence at the next rounds for signs of a slowdown, and whether Mercedes maintains its development lead in the constructors' fight.
