As Bono, Lewis' Race Engineer, said over the radio after he crossed the line fourth, "the Championship wasn't won today. It was won through a season of solid work and some f*****g great driving".
So many details go into winning a Formula One World Championship. From consistent results, to strong reliability, hard graft, constant learning, mental resilience... we could go on and on. It's a complicated, ambitious and challenging target to reach, but that makes the success feel all the sweeter.
For Lewis, the dust is starting to settle on a whirlwind weekend in Mexico, where we faced tough tests and struggled to fourth and fifth with our cars. But, crucially, that fourth place was enough for Lewis to wrap up title number five with two rounds to spare.
It wasn't the ideal way to win a World Championship. But, once it's yours, nothing else matters and you wouldn't want to change the road you took to get there. This season, we've faced our most difficult and intense battle of the Hybrid era. Ferrari started the year strong and have been relentless opposition, while Red Bull have put up a good fight too.
For Lewis to secure the Drivers' title at round 19 of an immensely competitive and tricky 21-race season is proof of the strong form he's been in all year long. In fact, we'd go as far as saying he's in the best form of his Formula One career so far.
