Lewis dominated on Sunday to score his fifth British Grand Prix win and slash Sebastian Vettel's points lead to just a single point.
Lewis: 'This has got to be one of my sweetest wins here'
It was Lewis' fourth win of the season and his fourth in as many years at Silverstone. The Brit led from pole, took the win, claimed the fastest lap and led every lap of the Grand Prix to secure his fifth career Grand Slam.
"I'm so happy... this has got to be one of my sweetest wins here," said Lewis. "I was gunning for this victory. There was so much negativity ahead of the race, with people questioning how I prepared for the race. But this weekend has been one of my strongest of the season.
"I made a solid start and then after that I managed the car and the balance, and the boys did a fantastic pit stop. I really can't find a fault at the moment. The team did an exceptional job this weekend and Valtteri obviously drover a stormer today - I'm proud of him. It's great to have him in the team.
Lewis: 'This result really opens up the championship'
"I'm surprised to see the issues the Ferrari had because I didn't see any debris. I did not expect to come away from this weekend just one point behind Sebastian. This result really opens up the championship - and we go to Hungary next, where I've always gone well.
"Every time I came around Turn 7, I could see the fans cheering every single lap. It was really reminiscent of 2008, my first Grand Prix win here. I've got some great supporters here, not only in the crowd, but in the garage as well. I've got my brother here, some of my aunties and family has come too. There's this amazing young kid who's come from South Africa, Michael, who is fighting cancer. It was amazing to see him. And Billy Monger is with us, who is just such an inspiration.
Valtteri: 'What a race, I'm really happy for us as a team'
Valtteri started down in ninth after taking a penalty for an unscheduled gearbox penalty, but the Finn fought his way back past the Ferraris to take second and complete the team's second 1-2 of 2017.
"What a race, I'm really happy for us as a team to get the second 1-2 of the season," said Vatteri. "Of course I would have liked to win, but I'm happy anyway because that was definitely one of my best ever races.
"I had to fight hardcore out there a couple of times, but I ended up in a good position. We could actually go longer than expected in the first stint on the Softs and the tyres were really good. In the last stint the team told me to just take care of the tyres, because we saw a few failures out there for some other teams, but for me they were fine.
"We're just at the half-way point of the season and it could definitely be worst. It's still just my first year with the team and I'm still right in the championship fight. As a team we did a really good job today. The strategy right from the start of the race worked really well. It was a flawless race for us and the 1-2 was our prize - the team really deserve this.
"We definitely got lucky with Kimi's puncture in the end, to take P2, but that's racing and today luck was on our side."
Toto: 'I think that was probably the best race I have been part of'
Toto Wolff was delighted with the result on what was an extra special day for the Silver Arrows, but issues a reminder that there is still plenty to play for before the summer break - with more points up for grabs in Budapest.
"I think that was probably the best race I have been part of since joining the team in 2013," said Toto.
"We are so delighted for Lewis: he prepared for the weekend in the way he knew was right for him, then came here and delivered in qualifying and the race. He got pole, led every lap, won the race and also set the fastest lap; it was a perfect performance.
Toto: 'Well done to everybody in Brixworth and Brackley'
"And then Valtteri rounded it off for the team by climbing all the way from P9 to P2, with a little bit of good fortune along the way but applying consistent pressure on every lap of the race. He picked his way through the field, kept the performance in the tyres at the right time and he richly deserved his second place finish; it was a brilliant drive.
"We are now at the halfway point of the season with 250 points still to score. There will be a lot of talk about the championship standings but not within the team. We have our eyes on one thing only and that's the next race in Hungary, so we can go into the summer break in an even stronger condition.
"Well done to everybody in Brixworth and Brackley for this result - it's a true credit to the amazing work you have done so far this year."
James: 'It feels like we are starting to build some good momentum'
The team strengthened its hold on the Constructors' Championship with a second 1-2 of the year, and Technical Director James Allison is looking for another big performance in Hungary to head into the summer break on a high note.
"This is a sport that asks so much of the people who compete in it, drivers and teams alike, and it is on days like these that it repays every tiny bit of effort one hundred fold," said James. "They are beyond description in the degree of pleasure, satisfaction and joy that they bring us all.
"Lewis has all but wiped out the deficit to Vettel in one hammer blow and the team has taken another big leaps in the constructors' race thanks to a tremendous display from Valtteri, whose work this afternoon completely erased the gearbox penalty he was forced to take this weekend.
"It feels like we are starting to build some good momentum in recent races and hopefully we can deliver the same sort of performance in two weeks' time before heading into the summer break. Our work in the next fortnight will focus on optimising every single detail so that we arrive in Hungary prepared for all of the challenges that race can throw at us."
Lewis now sits just a single point behind Vettel in the Drivers' Championship, with Valtteri a further 23 points back in P3. With a second 1-2 of the campaign, the Silver Arrows have stretched their Constructors' Championship lead to 55 points from Ferrari.
