Mercedes Defies F1 Trend with Bold Move at United States GP

Mercedes and Haas are the only teams bringing upgrades to the United States Grand Prix at Austin on October 19, while rivals prioritise 2026 preparations.

Nine teams arrive without new parts, reflecting a late-season development slowdown under the shadow of major rules changes.

Mercedes introduces a small, targeted package featuring a reprofiled upper lip and reduced rear-corner winglets.

The tweaks aim to clean airflow around the top wishbone and increase tyre clearance, improving handling consistency and degradation.

Gains are likely incremental, but valuable at a bumpy, wind-sensitive circuit with long stints.

Haas counters with a comprehensive VF-25 revision centred on the floor, plus revised fences, edges, sidepod inlets, and a rear-corner winglet.

The objective is stronger floor load across ride heights and better robustness over COTA’s bumps and kerbs.

Esteban Ocon will run the package in the single practice session to gather correlation data; Oliver Bearman has a second set available.

One hour of running compresses evaluation, increasing risk on setup and parc fermé direction.

For Mercedes, improved flow structures should help balance stability and tyre management over Austin’s punishing traction zones.

For Haas, any aerodynamic efficiency gain could lift race pace and strengthen points prospects in a tight midfield.

The field’s conservative stance underlines the resource shift toward new architecture, power unit integration, and aero concepts for 2026.

The payoff for both teams hinges on correlation, tyre wear, and wind sensitivity through sector one and the final sequence.

The United States Grand Prix concludes the assessment on October 19 at the Circuit of the Americas, with both teams under close scrutiny.
