James Allison, Technical Director, accepted the Constructors' trophy on behalf of the team.

Valtteri Bottas: First of all huge congratulations to Lewis - six championships is an impressive achievement! He had a strong season and he deserves the title, he was better overall. Lewis is a tough opponent, he has very few weaknesses, makes almost no mistakes and drives very consistently. But I've been gaining some good momentum, so I'm looking forward to another close fight with him next year. It's been a really good weekend for me and the team. I struggled at this track in previous years, so it was great to cross the line in first place. It was not an easy race; I had a strong start and a good first stint, but we had to switch to a two-stop to cover Max and I was a bit worried that Lewis on the one-stop might be on the better strategy. It was a proper fight and quite a bit of fun; I had to really push, but my pace was strong and I managed to catch Lewis towards the end. We had a good battle on track and I passed him to secure the win. It feels really good to win the race like that when you have to really fight for it.

Lewis Hamilton: It's hard to explain what I'm feeling right now, to be honest. Cloud nine doesn't even get close, it's somewhere far above that. It's been the hardest year I can remember; it's been so challenging, going through the ups and downs, so right now I'm just so full of emotion, it's overwhelming. I feel truly humbled, and really, really grateful to everyone back at the factories, the entire Daimler family and everyone at Petronas - everyone who has worked so hard to enable us to do what we do and achieve this. It's such a privilege and honour to work for this team, to be able to go out there and have the platform to put in performances like today. And Niki, I miss him so much. Today, he'd have taken his cap off. I wouldn't have been able to do this without Niki, he's here with us in spirit. I saw my parents right after the race and seeing my dad's smile, it says it all. My family have supported me since day one, they worked so hard for me to be here today. I'm so glad they could all come out here, together. Yesterday was a difficult day and today I just wanted to recover and deliver a one-two for the team. Valtteri did a fantastic job, so huge congratulations to him.

Toto Wolff: I'm so proud of everyone - what an incredible achievement! There's a massive amount of work behind the scenes to secure a result like this, where one driver claims the Championship and the other one wins the race. A massive thank you to everyone who contributed to this - here at the track, back at home in Brackley and Brixworth, at Daimler in Stuttgart and at Petronas in Kuala Lumpur. Taking his sixth drivers' title is a truly remarkable and special achievement. You can see how motivated Lewis still is, he wants to win every race and get the best result possible. It's not been an easy year, with tough competition and the loss of Niki. I'd like to think Niki's looking down on us, tipping his cap after today's result. Valtteri drove an absolutely faultless race today, he has been on incredible form all weekend and he thoroughly deserved the victory. Lewis fought back in style and put in a great drive to go from P5 to P2.

James Allison: The amount of effort it takes to win a championship is huge, so when it all comes to the final fruition, you just swell up with great, great pleasure - and to have the cherry on the cake of standing on that podium looking out on our team and everybody in the crowd was fantastic. It's brilliant to be part of this team - it makes you really keen to work, it takes you way above and beyond what you would normally give because you're surrounded by all these people that you don't want to let down and you enjoy being in an environment that is supporting you, letting you take risks, letting you screw up, but not slapping you in the face for it, just urging you on collectively as you go. It's an exciting place to be and it tends to make people want to be in it. Today, we all think of Niki who was such an important part of our team. Losing him was quite a massive blow, particularly to Toto who spent so much of his working life with him, but for all of us as well, because Niki was someone with such a big personality, such a huge figure in our sport and such a friend to the team. I think he would have appreciated this - doing it in such fine style this year, he would have seen this as a team at the top of its game. He'd probably be telling us to work on next years car now, but I think we've done him proud this season.
