Ferrari boss Fred Vasseur confirmed that development on this year’s car will stop after the next F1 race in Austin – as key figures started their roles at the Scuderia this week ahead of Lewis Hamilton’s impending arrival.

Jackie Stewart has remarked it is "unusual" for Lewis Hamilton to move to Ferrari at a late age and said it will be his "biggest challenge."

Lewis Hamilton will end his 12-year association with Mercedes’ F1 team to join Ferrari in 2025. It is being billed as one of the, if not the, biggest driver transfer in the sport’s history. However, legendary F1 driver Sir Jackie Stewart cannot help but feel surprised.

Lewis Hamilton will be 40 years old by the time he's driving for Ferrari and Sir Jackie Stewart questioned whether the move could have been made earlier.

F1 icon Jackie Stewart feels Lewis Hamilton has proven he still has the quality to compete when he joins Ferrari next year, but there will naturally be concerns as he approaches his 40th birthday. Hamilton's 10-year stint with Mercedes will come to an end this winter when he leaves to join Ferrari in a blockbuster move ahead of next season.
