The Mercedes star is gunning for his sixth Drivers’ Championship title this year, which would put him just one away from being the joint all-time most successful driver ever.
But the 34-year-old has already started considering what he will do after he walks away from the sport.
Formula E, the electric-powered car series, has become a true competitor to Formula 1, and Mercedes will be joining the grid next season.
And though Hamilton is under contract to drive in F1 until the end of the 2020 season, he revealed that watching former drivers exploring different driving series has made him think about his own future.
Speaking at an event for Mercedes’ 125th anniversary of competing in motorsports, the Stevenage star hinted he could be interested in either Indycar or Formula E.
“That is something I have kind of been debating,” he said to The Sun.
“Up until now it has always been about Formula One, but I just drove an old DTM car today, which I really loved.
“I rarely get to a track these days and have some fun, so that experience was extraordinary.
“It was so cool driving my 2015 car and then the 196.
“It was a unique experience.”
Hamilton’s future has always been a hot topic amongst F1 fans, with many predicting that he will want to drive for Ferrari before he calls it a day.
And the five-time champion admitted that he has been thinking about his retirement, and what he will do next.
“Being that I have been racing since I was eight years old, I am going to have massive withdrawal symptoms, like every driver has when they stop racing, when Formula One stops for me,” he continued.
“There are other things to do, I guess there are other series I could do.
“Fernando Alonso is doing Indycar and you see Kimi Raikkonen still pushing the boundaries.
“I actually grew up in the same era as Gary Paffett, he is a little bit older than me and is now racing in Formula E and that is now going to be the future.
“So, who knows, in the future that’s maybe an area where I can use my skills but as you get older, it is more challenging to find the motivation to stay focused and you have to find something you love.
“I am pretty sure I will always love cars, and for now I am going to try and stay in Formula One, so long as I stay focused and fit, I will carry on driving the best that I can.”
