What happened: The aerodynamic package pairs a reshaped sidepod inlet and deeper undercut with a modified floor board to connect airflow along the chassis. Those changes arrive at Circuit of the Americas as part of a four-component revision that also updates the diffuser.

Why it matters: Late-season underbody refinements give Ferrari, which captured its 250th Formula 1 victory at the British Grand Prix, a final baseline test of its 2026 aerodynamic platform across Austin's mix of high-speed directional changes and slow corners. Correlating trackside airflow data from the front floor edge directly informs development over the closing rounds of the campaign.

What to watch: Remaining sessions in Austin will test whether the revised floor edge stabilizes downforce across the circuit's bumpy braking zones and first-sector esses.
