In Russell and Antonelli, Mercedes have a much-less experienced driver pairing, particularly when it comes to race victories and podiums.
The team are hoping to get closer to Red Bull, Ferrari and McLaren in 2025, having finished a distant fourth in Hamilton's final season with the Brackley-based outfit.
Both Russell and Antonelli will hope to be able to compete for regular race victories, and maybe even make a challenge for what appears to be a wide-open drivers' championship.
Now, ahead of the new season, Mercedes have revealed a new release in a social media announcement, introducing Antonelli's all-new race helmet.
The Italian's first season in F1 will see him sport a predominantly blue design, with a heavy Italian flag influence on the sides, with a blur of green, white and red.
Antonelli also posted the new design to his Instagram page, with the caption: "Ready to race."
