Yesterday in Austin, the F1 Sprint provided an eventful, albeit somewhat uneventful, start to the weekend. The finishing order largely reflected the chaos caused by a dramatic incident at the start, which involved Oscar Piastri, Lando Norris, and Nico Hulkenberg, with indirect consequences for Fernando Alonso.
Pirelli opted for a different tire range compared to last year, removing the C2 compound and introducing the C1 as the Hard option. Many expected some drivers to risk using a C4 Soft in the Sprint to test its performance ahead of today’s Grand Prix. However, the heat prompted nearly all drivers to run a Medium set. Those with an extra set mounted it fresh, while others, like Ferrari, used a previously run set. This already gives a clear indicator for today’s race strategy.
Pirelli’s strategy guidance – COTA, 56 laps
Following the Sprint and Pirelli Motorsport director Mario Isola’s analysis, options are somewhat limited. “The Hard tire is again a valid strategic option. Its performance gap to the Medium is smaller than expected. All compounds could play a role. Extending the first stint on Mediums to between laps 20 and 26 could allow a one-stop strategy, switching to Hard C1 to reach the checkered flag,” Isola explained.
“Two-stop strategies using Soft and Medium are also feasible. Starting on C4 Soft, a pit stop between laps 12 and 18 to switch to C3 Medium, followed by either another Medium or Soft, is a viable option,” he added.
According to Isola, a single stop is realistically only possible using Medium and Hard; otherwise, maintaining competitive pace would be very difficult. “Avoiding a second stop with Medium and Soft would require extremely careful tire management, leaving drivers exposed to sudden performance drops. That’s why it’s not a very realistic option.”
Drivers will also need to account for external factors such as wind gusts and surface irregularities. “Wind increases the risk of lock-ups under braking, affecting tire management, while bumps and undulations can cause micro-jumps that raise tire temperatures, complicating thermal management.”
Strategies shaped by heat and Safety Car
We agree with Isola’s assessment: the Medium-Hard one-stop strategy remains the most likely route in a straightforward race. Track temperatures will be cooler than yesterday but still approach or exceed 40°C. If the Hard C1 performs similarly to the Medium C3, the Medium-Hard strategy will allow drivers to complete all 56 laps in the fastest time possible.
The C3 Medium is expected to be the primary race tire. With careful management, a one-stop Medium-Soft strategy could be possible, but only under ideal conditions. As noted by Pirelli, it’s challenging and nearly impossible in a linear race. However, Safety Car periods, especially in the early stages, could extend stints on Mediums and make a Medium-Soft one-stop a valid alternative.
Additionally, a Safety Car in the second half of the race could create a “free” pit stop opportunity, increasing the likelihood of a two-stop strategy. A Soft tire could be used for the final stint, or even a well-managed Medium could provide competitive performance in the closing laps.
Every driver on the grid has one fresh Hard and one fresh Medium set, and at least one used C3 set. With so many variables, all strategic options remain open.
