Andrea Kimi Antonelli, an 18-year-old Italian driver, has officially been confirmed as the successor to Lewis Hamilton at Mercedes, marking a significant step in his promising career. Despite a challenging debut where he crashed just minutes into his first practice session at Monza, he is viewed as a phenomenal talent similar to Hamilton and Max Verstappen. Teammate George Russell has acknowledged Antonelli's speed but anticipates common rookie mistakes. The decision to hire Antonelli comes amid speculation about a potential future acquisition of Verstappen, with former driver Nico Rosberg suggesting the upcoming season will be a 'shootout' between Antonelli and Russell for a position at Mercedes. Antonelli has also secured the No.12 race number, inspired by his idol Ayrton Senna. The 2025 season looms as a crucial testing ground for Antonelli as Mercedes seeks to regain its competitive edge.
