Leclerc Tops Opening Miami Practice as Antonelli Hits Trouble

Charles Leclerc set the fastest time in the opening practice session for the Miami Grand Prix, leading the field with a 1m29.310s. The Ferrari driver finished nearly three-tenths clear of reigning champion Max Verstappen, while McLaren's Oscar Piastri and Leclerc's teammate Lewis Hamilton completed a tight top four. The session was marked by a premature end for Mercedes rookie Kimi Antonelli, who stopped on track with a suspected power unit issue after showing strong pace inside the top five.

Why it matters:

The first practice session in Miami offers the initial glimpse of the competitive order for the weekend, setting the tone for the Sprint Qualifying that follows just hours later. Ferrari's strong showing, with both cars at the sharp end, signals potential for a challenge to Red Bull's dominance at a circuit where performance can be unpredictable. Antonelli's reliability problem, however, throws an immediate curveball into Mercedes' preparations for a critical Sprint weekend.

The Details:

• Ferrari Frontrunner: Charles Leclerc's benchmark time of 1:29.310 gave Ferrari a solid start, with Lewis Hamilton close behind in fourth, just 0.019s behind Piastri.
• Red Bull Response: Max Verstappen slotted into second, 0.297s off the pace, while his teammate Isack Hadjar managed ninth, over 1.5 seconds behind the leader.
• Antonelli's Early Stop: The promising session for Mercedes' Kimi Antonelli, who was fifth fastest, ended abruptly when his car stopped on track. The team reported a suspected power unit issue, cutting his run short at 24 laps.
• Midfield Mix: Alpine's Pierre Gasly led the midfield pack in eighth, ahead of the Red Bull of Hadjar and the Williams of Carlos Sainz. The times from eighth to fifteenth were covered by just over one second.
• Teams on the Back Foot: Cadillac (formerly Sauber) and Aston Martin appeared to struggle, with Sergio Perez, Fernando Alonso, and Lance Stroll filling the bottom four positions on the timing sheets.

What's next:

The focus immediately shifts to Sprint Qualifying, which begins at 4:30 PM local time. Teams have minimal time to analyze data and make adjustments, putting a premium on their initial FP1 learnings.

• All eyes will be on Mercedes to diagnose and potentially resolve Antonelli's power unit problem before the competitive sessions begin.
• The session will test whether Ferrari's early pace is genuine and if Red Bull can find more performance from its RB22. The compressed schedule means every lap and every decision carries extra weight for the rest of the Miami weekend.
