F1 Miami GP: Extended FP1 kicks off Sprint weekend with crucial data gathering

Formula 1 teams tackled a uniquely extended 90-minute FP1 session in Miami, using the valuable extra track time to test upgrades and gather critical data for the compressed Sprint weekend format. The session extension, unanimously agreed upon by teams due to recent power unit regulation tweaks, provided a vital window for understanding car performance under new energy deployment parameters ahead of the only other competitive session: Sprint Qualifying later today.

Why it matters:

In a Sprint weekend, FP1 is the sole practice hour before the competitive sessions begin, making every lap of data collection priceless for car setup and strategy. The extended session was particularly crucial this weekend as teams adapt to technical directive clarifications on energy deployment and recharge, which can significantly alter car balance and tire management on Miami's demanding circuit.

The details:

• The 90-minute session length was a one-off agreement for Miami, prompted by the need for teams to understand their cars under updated energy management rules following a recent FIA technical directive.
• With Sprint Qualifying and the Sprint Race following in quick succession, teams had to balance gathering long-run tire data with optimizing single-lap performance for the imminent qualifying shootout.
• Several teams, including Ferrari and McLaren, brought visible upgrades to Miami, making FP1 their first and only chance to validate these new parts in real track conditions before committing to them for the rest of the weekend.
• The session served as the primary opportunity for drivers to reacclimate to the bumpy, technical Miami International Autodrome layout and its often-slippery surface conditions.

What's next:

The compressed schedule now accelerates dramatically, with the data from FP1 immediately being analyzed to finalize setups for Sprint Qualifying. Teams face a high-stakes trade-off: use the learnings to find a compromise setup for both the short Sprint Race and Sunday's Grand Prix, or aggressively tune the car specifically for the next few hours of competition. The limited practice makes any misstep in data interpretation or setup choice particularly costly for the remainder of the weekend.
