Mercedes reveal Hamilton's "secret" fitting for '19

Mercedes have revealed Lewis Hamilton's "secret" seat fitting for his car for next season, as he looks to win his third successive world title.

The reigning world champion has now completed his seat fitting for the 2019 season, with Mercedes releasing a video on Instagram revealing the completion.

Hamilton joined his team-mate Valtteri Bottas at the Mercedes factory in Brackley this weekend for the Silver Arrows' Christmas party.

Both drivers met children, and their families, from the Make-a-Wish Foundation; who were being treated to a tour of the Brackley-base.

Whilst there, Hamilton and Bottas also undergone their respective seat fittings for the 2019's W10. The new car will feature the revised aerodynamic regulations introduced in 2019, with the owners Liberty Media aiming to enhance the excitement levels in Formula 1.

Hamilton was filmed trying the new steerling lock and he was also preparing the setup for his new 2019 cockpit in a test chassis.

Mercedes will be looking to continue their dominance of Formula One next season, aiming for another double - but the 2019 season could give them even more challenges.
