Despite only being 18-years-old, Antonelli has enjoyed an illustrious junior career to justify his rapid promotion through the motorsport ranks.
The Italian currently competes in Formula 2, and has claimed two wins at Silverstone and Hungary, despite the performance of his Prema car holding him back this season.
In addition to two F2 wins, he also has various feeder series titles to his name including Italian F4 and the Formula Regional European Championship.
Antonelli has also achieved multiple karting championships, and even competed within an F1 champion’s team.
Nico Rosberg revealed that Antonelli raced for his team, Rosberg Racing Academy, where even then he displayed the talent that has excited Mercedes’ bosses.
“Kimi Antonelli raced in my go-karting team when he was a little kid,” Rosberg said on Sky Sports in July.
“He’s phenomenal. He’s Max Verstappen-level. It’s really unbelievable.”
Ahead of the Italian GP, Rosberg has also unveiled more information about Antonelli’s junior career, including the financial aid the youngster received.
The Mercedes champion dropped his former boss in it when Rosberg revealed he had to subsidise some of Antonelli’s karting career.
“Toto didn’t even pay the full budget I had to subsidise, but I was happy to,” Rosberg added on Sky Sports.
