In this episode of Sideline Story, we examine how Kimi Antonelli became Formula 1's youngest world champion at just 20-years-old. Was his historic triumph down to Mercedes' competitive advantage, his own driving brilliance or a combination of both? We also explore why teammate George Russell trails Antonelli by 130 points, despite racing for the same constructor. Finally, we look ahead to a 2027 grid set to feature five world champions and discuss speculation surrounding Chinese automaker BYD's potential entry into Formula 1.
