Lewis Hamilton feels he has never seen a team as hungry for success as Mercedes.

On Thursday, Hamilton addressed the staff at the Brackley-based marque for the first time as he embarked on a new chapter in his Formula One career. Despite questions hanging over Mercedes over the leadership of the team and Ross Brawn's position as team principal, Hamilton's arrival on a three-year deal worth £45million will prove an invigorating tonic.

With just one grand prix win in the last three years since Mercedes returned to the sport after taking over Brawn GP, Hamilton could at least sense the desire to address and reverse their fortunes, and he said: "Everything feels really positive for me. The guys are working really hard."

Hamilton, bristling with enthusiasm and confidence at the task ahead, added: "It's important they are always analysing and seeing what can be improved, what adjustments need to be made because they want to win.

"That's a big positive for me, to see they are not scared of making changes, not scared of doing whatever they have to do to win.

"I believe in all the people in this team. There is a great spirit here, as with my previous team, and the guys seem hungrier than any group of people I've seen before. They seem seriously hungry to win and excited they have another shot at it this year."

That would appear detrimental to the desire Hamilton often spoke of within McLaren during his six years in F1 with the team.

Clarifying, he added: "Every year there was always a great atmosphere at McLaren. But it's obviously a different environment to come to, a different kind of factory, a different feeling I have here because it's new and fresh. The guys seem to be just as on it, if not more."

As for his personal message to the workforce, Hamilton said: "Just that I will be flat out all the way and working as hard as I can to drive them to success.

"It's not a one-man band, it's a team effort, and whilst they are putting in 100 per cent, I'll be doing exactly the same."
