Kimi Antonelli became Formula One's youngest world champion at 20 years and 68 days old on Sunday when he finished third in the Mexico City Grand Prix behind race winner Max Verstappen and Lewis Hamilton.

The previous recordholder was Germany's Sebastian Vettel , who first became a world champion at age 23 in 2010.
