HOCKENHEIM, GERMANY (REUTERS) - Four-time Formula One world champion Lewis Hamilton ended months of speculation about his future on Thursday (July 19) by signing a new two-year deal that will keep him at Mercedes until the end of 2020.
The 33-year-old Briton would have been out of contract at the end of this season and the negotiations have been a major talking point in the paddock.
No financial details were given but British media reports have suggested the new deal could be worth up to £40 million (S$71.3 million) a year.
Thursday's announcement is now likely to trigger other driver decisions, with Australian Daniel Ricciardo set to remain with Red Bull but waiting for confirmation of Hamilton's contract.
"This contract extension has basically been a formality since (team chief) Toto (Wolff) and I sat down during the winter, so it's good to put pen to paper, announce it and then get on with business as usual," Hamilton said ahead of Sunday's German Grand Prix.
"I have been part of the Mercedes racing family for 20 years and I have never been happier inside a team than I am right now," he added.
"I'm very confident that Mercedes is the right place to be over the coming years."
While Hamilton had been expected to stay with the team that have won both the drivers' and constructors' titles for the past four years, there had still been some lingering doubts about his commitment to the sport.
Former team-mate Nico Rosberg stunned the team in 2016 when he won the title and then announced his retirement only days later.
Hamilton, who won his first title with McLaren, enjoys a celebrity lifestyle with plenty of interests - mainly in music and fashion - outside of Formula One and there have been questions about how long he will race on for.
The Briton said on Thursday that he was still hungry for success on the race track.
"The competitive passion that burns bright inside me is shared by every single member of this group - always chasing the next improvement and digging even deeper to make sure we come out on top," he said.
"I can't wait to see what we can achieve together in the next two-and-a-half seasons."
The Briton is currently eight points adrift of Ferrari's Sebastian Vettel, also a four-time world champion, at the halfway point in the season.
Wolff recognised there had been plenty of speculation in recent months and was happy to put it to bed.
"It's good to put all of that to rest and get this thing announced," he said.
"We signed the final documents this week and didn't want to keep people waiting any longer."
