Hamilton has a chance to reclaim the lead of the championship at Silverstone, where he starts from a record sixth pole position on Sunday afternoon, while teammate Valtteri Bottas starts from behind the two Ferraris in fourth.
2016 Formula One world champion Nico Rosberg has dismissed the idea that Kimi Raikkonen deliberately hit Lewis Hamilton on the opening lap of the British Grand Prix.
The race had 15 laps left to run when it resumed on lap 37, but Romain Grosjean and Carlos Sainz crashed into each other one lap later, triggering a second safety vehicle that absorbed another precious three laps for the Mercedes drivers.
Despite Hamilton making insinuations about Ferrari's "interesting tactics" on the podium after the British GP, he clarified on Monday that he accepted Raikkonen's apology.
Vettel crossed the line an ecstatic man, recording Ferrari's first win at the Mercedes-dominated circuit since 2011 and Vettel's first victory in England since 2009. Pierre Gasly was 10th for Toro Rosso.
"It looked very tight at the front on Friday and so it proved in qualifying: it needed a very good lap from Lewis to put the auto on pole and, save for an error in the final corners, Valtteri would have been just behind".
"But it was crucial, it wasn't easy, they seemed to be very strong on the straights, the mid part of the straights but yeah, obviously with DRS and a tow, I was a bit stronger at the end of the straights so it worked". "I think it's working well on these kind of tracks but to be honest everywhere it works quite good".

Brendon Hartley's miserable weekend continued as his Toro Rosso was wheeled back early. "In France I lost my wing so I screwed my own race", he said. His team-mate Daniel Ricciardo finished fifth. Hamilton sliced past him on the next lap to steal second and Raikkonen relieved him of third on lap 49.
A furious finale to match the frantic first lap looked certain when Ericsson then crashed at Turn One. There was a delay before the Swede emerged from his vehicle, but the fact he did so apparently unharmed speaks volumes for the improvements in safety in F1.
In both cases, the penalty did not seem sufficient to satisfy Mercedes, or their drivers, after their races were wrecked by rivals' mistakes.
As at Spielberg, Hamilton was concerned by the decision.
"I said you need to question whether it was incompetence or deliberate - a stupid comment of mine in the emotion", he said. "You're the fastest out there by miles", he said.
Once released, the safety vehicle barely had time to wind its windows back up before it was required again, Carlos Sainz and Romain Grosjean squeezing eachother and ending up in the gravel at Turn 1.
On re-start, at Stowe, Bottas pulled away.
