Winning the race from P14 on the grid was a big ask. But through all the German GP drama, Lewis managed to do just that.
"It's obviously very, very difficult from that position and highly unlikely - but you've always got to believe," he explained afterwards.
"We did the parade lap, I could see how much support I had out there and I just wanted to stay collected, stay calm.
"The team did such a great job, the car was fantastic today. Honestly, I'm so grateful. So grateful for the hard work the team has done. Hopefully this solidifies their belief in me.
"Ultimately, on a day like this there is a chance to show what you can do. I feel like I drove the best that I can remember driving. I didn't make any mistakes.
"Obviously, I've done a lot of races and there have been other great races. Silverstone 2008 was pretty great but I went off. It was 99.8%. This one, I didn't make any mistakes at all. It was a dream.
"I would never have thought you could do something like that - but I just kept pushing, I kept believing and it happened."
