Despite being turned around on the opening lap and falling to last place, Lewis still believed he could fight back to the front and he did just that.
"The fans have been incredible this weekend," he said. "Obviously, we're in a tough battle this year and it's the most intense battle that I think we've probably all had but I'm very, very grateful that the car was still in one piece after the Turn 3 incident.
"I was last at that point, but I still believed that I could win - and I needed that mentality to make it back.
"At the beginning, I thought I'd lost something on the rear end but when I looked at the car afterwards, it seemed to be OK and it was driving better and better throughout the race.
"To get back to second is huge for us and I will definitely take it, of course. I'm happy with the drive that I did and as I said, what the team were able to do but, yeah, we've just got to work harder."
