Certain things are unknown for the 2022 season and how the new regulation changes will affect the standings, but it is expected that racing will be far more competitive.
And leaving Mercedes for one final challenge may be the perfect way for Hamilton to leave the sport.
He’s once again the favourite to win the title this season and, should he do so, he will hold the outright record for most F1 titles in the sport’s history.
At 36 years of age, his next contract may well be his last with Hamilton previously stating that he’s unlikely to follow in the footsteps of Kimi Raikkonen and Fernando Alonso by racing when he’s in his 40s.
And with nothing left to prove in the sport, Hamilton may relish the opportunity to join a team tipped for a bright future with huge financial backing.
There would also be the added bonus for F1 fans to finally see Vettel and Hamilton race alongside each other in the same car after years of rumours regarding the pair teaming up.
