He has won four of those with the Silver Arrows, with team winning the double in each of the past five seasons.
It was more difficult this time round, though, as Ferrari led both Championships at the halfway stage.
At the FIA Prize-giving ceremony in Saint Petersburg on Friday, Hamilton acknowledged his Mercedes team.
“I wouldn’t be up here without this incredible team, I’m just really a chink in the chain,” Hamilton said.
“There’s so many people in the background who are the unsung heroes.
“We’re the ones who come up here and are seen and receive these great awards, but it couldn’t have been done without this great team.
“It’s been a real privilege being with Mercedes-Benz the last six years.”
He wants to “raise the bar” and he could go after Michael Schumacher’s record of seven titles.
“It’s crazy to think that it’s my 12th season but we’ve just got to keep pushing, keep trying to raise the bar,” he added.
“This does feel incredible. I don’t think it’s really going to kick in.
“I don’t know how it is for the other champions here, but it just feels like a normal day – but of course it’s a real privilege to be up here and receive this award.”
