Mercedes rookie Kimi Antonelli expressed his growing confidence ahead of the Miami Grand Prix, where he replaces seven-time champion Lewis Hamilton, now at Ferrari. Having scored points in four of the first five races, Antonelli sits sixth in the standings, crediting his progress to increased confidence in the car, though he acknowledges the challenge of balancing aggression and caution. As the second F1 Sprint weekend of 2025 approaches, he reflected on the differences in format and how his experience in Formula 2 has prepared him for the unique demands of sprint weekends.
