Lewis Hamilton and Mercedes boss Toto Wolff's have reportedly engaged in a..

Lewis Hamilton’s uncertainty over remaining with Mercedes for the rest of his career was apparent in a conversation he held with team principal Toto Wolff during the 2023 Formula 1 season, the release of season six of Netflix’s Drive to Survive has revealed.

The latest series of the documentary has an episode focused on Hamilton considering his future with the team amid a second successive disappointing campaign for Mercedes.

Hamilton ultimately signed a contract extension with Mercedes in August that was expected to keep him with the team until the end of 2025, but he then stunned the sporting world earlier in February by taking up a break clause to join Ferrari for the 2025 season.

The behind-the-scenes footage provides insight to the mindset of the seven-time world champion, who appeared to be having doubts over remaining with the Silver Arrows.

The conversation between the pair shows Hamilton expressing his concerns over Mercedes’ lack of performance and Wolff attempting to convince the Brit that he should remain with the team until and beyond the end of his driving career.

Hamilton replies: “Frick, me neither. You can be here for like 20 more years, 30 more years, I can’t.”

Wolff responds: “Well, who says that?

Before in what now appears to be a foreboding remark, Hamilton says: “These are precious years for me. I don’t know.”

Attempting to ease Hamilton’s doubts, Wolff says: “Lewis, you’re much more than a racing driver, much more than the seven-time world champion. You are one of the people that lead this team forward.”

Ahead of his final season with team, Hamilton is set to make his 2024 pre-season testing debut on Thursday, live on Sky Sports F1, after team-mate George Russell drove the W15 on Wednesday.
