The outright pole position record holder, Hamilton now only sits behind Michael Schumacher in terms of race wins and titles earned - both records which Hamilton could equal in 2020.
"I think at this time of the year you don't really feel any pressure and it's just about having some fun", the 35-year-old said.
Mercedes will reveal the first images of its new auto on Friday when it takes to the track at Silverstone for a 100km shakedown ahead of pre-season testing next week.
"The guys have worked so hard to put the auto together and there are only two of us, Valtteri (Bottas) and I, who get to drive it".
Lewis Hamilton has unveiled the new Mercedes he hopes will fire him to a record-equalling seventh Formula One world championship.
"They couldn't be more excited or driven".
"It would be easy to be laid back".
And if he keeps up his win average of the past six years, he will surpass the German's other record of 91 Grand Prix victories. "It is a real privilege to have that position".
Hamilton shrugged off comments from Red Bull's Max Verstappen, who said at a media event last week that he could beat the Briton if he had the right vehicle, adding: "Lewis is very good".
Hamilton's design incorporates six stars on the side to represent his six world championships and also features his motto "Still I Rise", which is inspired by a Maya Angelou poem and the lyrics of Tupac Shakur. He is definitely one of the best out there but he is not God. I have just always known to do my talking on the track. "Often I tend to see that (talk) as a sign of weakness".
Bottas joins Hamilton in Mercedes line-up for a fourth season and will aim to build on his strongest campaign of F1 in 2019, when he won four times and finished runner-up in the championship.
Having beaten Ferrari's record of five successive title doubles previous year, the search for another clean sweep is therefore the Brackley squad's obvious target for the first season of the new decade.
The rear bodywork is noticeably more tightly packaged for better airflow, and there is the usual complexity of airflow shapers behind the front wheels. But their two rivals are hopeful of taking the fight to them.
The first images of W11, decked out in the revised livery which was first revealed earlier this week, were revealed online ahead of the car's track debut later on Friday at Silverstone.
"This is my eight year with the team and the buzz is the same every year".
