Hamilton is supposedly expected to sign a new record-breaking £40million two-year deal with Mercedes.
The Brit is keen to extend his stay and has set his sights on winning his fifth F1 world title this year.
Hamilton’s new deal could well likely be the last one with the team that he has lifted four Drivers’ Championships with.
The 33-year-old is three behind the record holder Michael Schumacher and is also trying to chase down the German legend’s feat of 91 career race wins.
And Hamilton is unsure how long he will remain with Mercedes.
He told the Daily Mail: “I don’t feel like I’m about to embark on my last contract at the moment, but it could be.
“I can’t predict how I’ll feel in three years’ time.
“I don’t know how long my excitement is going to last but, as long as I’m still feeling this way at the start of a season, I’ll keep going.
“People say, ‘You’ve won four titles, what keeps you going?’ I reset every year.
“It’s irrelevant what’s happened in the past. What’s relevant is what’s going to happen now.”
The new F1 season gets underway on Sunday with the Australian Grand Prix.
