Pirelli expects one‑stop as the benchmark strategy after Miami sprint race

F1 Grand Prix, GP Miami, Miami

Pirelli left little ambiguity after the main qualifying session in Miami: the 2026 Grand Prix is shaping up to be a race defined by tyre consistency, low degradation and the strategic discipline required on a circuit where neutralisations are frequent and track evolution is rapid.

Dario Marrafuschi, Pirelli’s Motorsport Director, offered a detailed assessment of the expected race strategies, reinforcing the view that Miami remains a venue where a single stop is not only viable but decisively advantageous.

Marrafuschi underlined that the tyre selection for the weekend — the C3, C4 and C5 compounds — behaved exactly as anticipated. “The one-stop strategy is confirmed as the fastest option for tomorrow, as we had already expected ahead of the race weekend.

The compounds selected for Miami have proven to be consistent and with low degradation. Extending the stints to make just one pit stop is therefore not an issue.”

The numbers support that conclusion. According to Pirelli’s modelling, a two‑stop race would carry a deficit of around ten seconds compared to a single‑stop run, a margin too large to justify unless a Safety Car or Virtual Safety Car intervenes at precisely the right moment. And in Miami, where incidents are common, that possibility cannot be dismissed — but neither can it be relied upon.

Pirelli’s projections place the Medium–Hard combination at the top of the strategic hierarchy. The Medium offers strong opening‑stint flexibility, while the Hard provides the durability required to close the race without significant drop‑off. Marrafuschi explained:

“On paper, the Medium‑Hard solution, with a pit window between laps 22 and 28, is the quickest and offers the advantage of flexibility in the event of neutralisations, which are frequent in Miami.”

This flexibility is crucial on a circuit where the Safety Car has appeared in every edition of the Grand Prix so far. Teams starting on the Medium can extend or shorten their first stint depending on race interruptions, track evolution or unexpected degradation patterns.

The Soft compound, the C5, has shown strong peak performance but limited longevity — a familiar pattern on the resurfaced Miami asphalt. Still, Pirelli believes it can be a competitive opening tyre for those seeking track position at the start.

“The Soft could be a valid option, exploiting its higher grip, when used in combination with the Hard. Starting on the C5, the pit stop should be made between laps 16 and 22.”

This approach is likely to appeal to teams or drivers who qualified out of position and need immediate gains. The Hard tyre’s robustness then becomes essential for managing the long closing stint.

The Medium–Soft pairing is technically feasible but strategically compromised. The Soft’s performance drop‑off late in the race would be difficult to manage, especially with the field tightly bunched after potential neutralisations.

Marrafuschi was clear: “Less effective in terms of lap time is the Medium‑Soft pairing, which would have a pit window between laps 32 and 38.”

This strategy risks leaving drivers exposed in the final laps, particularly if the race restarts with a Safety Car and the field is compressed.

Weather: The Wildcard
While the dry‑race simulations point strongly toward a one‑stop race, Miami’s unpredictable weather remains a significant variable. The circuit is known for drying unusually quickly — a characteristic demonstrated in last year’s Sprint, when drivers switched from intermediates to slicks within 19 laps despite heavy pre‑race rainfall.

Marrafuschi acknowledged that the forecast could still reshape the strategic landscape: “Obviously, the entire day will be influenced by the weather forecast, which could even lead to a wet race.”
