But for the British racing driver, the success was bittersweet, for Nicole Scherzinger wasn't with him to share his happiness and success.
Therefore Lewis, 28, dedicated the trophy to his ex-girlfriend, as he continues to show signs that he wants his Pussycat Doll back.
During an Sky Sports interview, Hamilton made his emotional tribute: 'I feel like, the thought on my mind through the entire race was of someone really special to me. And I want to dedicate it to her.'
Asked by the interviewer if that person was Nicole, 34, he smiled and confirmed her question.
Lewis then opened up about how trying it has been since they announced their split at the beginning of July.
Down in the dumps: Nicole does not look like she has been handling the break up well either
Downer: Lewis admitted he had been struggling over the last month since he split from his Pussycat Doll
It's been the toughest couple of months in my life,' Lewis confessed, So coming in to the race they [his parents] really wanted to lift my spirits keep my focus on and clearly it's not affecting my driving.
'But it just doesn't feel the same. A couple of years ago we were here together and I won, so I have great memories.'
However, Hamilton has had his parents rallying round to keep his spirits up, and help get him race ready for new team Mercedes.
In the past: When Lewis won the Hungarian Grand Prix in 2009, Nicole was by his side
Not the same: Lewis clearly misses his American girlfriend cheering him from the stands
And to come here after a real downer for the last few weeks, I really wasn't expecting [the win]'.
This isn't the first attempt to public reach out to Nicole by Lewis, as he wrote on Twitter last week: 'If you’ve found that special someone, don’t EVER let them go no matter what!! Nothing in this world is more important.'
And the driver has been using his music to come to terms with his emotions, tweeting from his recording studio: 'My hideaway – pouring my heart into this track!!'
Nicole has been equally heartbroken by the end of their five year relationship, with a source close to the X Factor judge telling the Mirror: 'They’d been talking about marriage so you can imagine how upsetting this whole thing has been for her.'
While Nicole hasn't publicly acknowledged Lewis's sentiments over the last few weeks, she has been looking downcast as she continues her X Factor UK duties and attending events on her own.
