His season was sealed with second place in Abu Dhabi, rounding off a Silver Arrows 1-2 and donuts on the start/finish straight with team-mate and race winner Valtteri. Because, well, why not? It had been quite a season for Lewis. He returned from the summer break with a 14-point deficit in the standings, but ended the year 46-points clear.
"The first half of the season was a little bit up and down in terms of extracting the maximum performance from the car," Lewis said, reflecting on the season. "Then, in the second half, understanding the balance, hitting the nail on the head most weekends and getting to the point of exploiting the car and my potential on a consistent basis was really the turning point for me.
"Often in a difficult race, you're applying the pressure, hoping that you can squeeze a little bit of a mistake from the driver ahead.
"I would say it's the same with the team: you're pushing right to the limit and squeezing every drop from the car, yet you've got to make it go quite a long distance in terms of life and reliability. That's where Ferrari was not the same as Mercedes. Nonetheless I'm looking forward to the tough battles that we're going to have next year."
It was an extraordinary, record-breaking, intense year for Lewis and he's determined to do it all over again in 2018.
