Daniel Ricciardo has claimed his first GP win with the Australian taking out the Canadian Grand Prix in a day full of drama.
Lewis Hamilton dropped out of the race after both Mercedes cars suffered a power problem at the top speed end, with smoke coming from the back of his car in lap 46 and the Brit being forced to leave the track with a break failure.
Mercedes tweeted: "That's it for @LewisHamilton: back to base and out of the car. A tragic way to end what was a fantastic rave from the man here in Canada."
They then added: "Apologies for the spelling error there, we're a little emotional..."
That left Nico Rosberg holding the flag for Mercedes but the German was unable to regain enough speed to keep the lead, with a five-way battle for first place ensuing as Rosberg, Sergio Perez, Felipe Massa, Ricciardo and Vettel all fought for the top position.
But on lap 65 Perez suffered a problem with his breaks, saying over the team radio: "I have no brakes left!" and on lap 69, as Ricciardo finally passed Rosberg to the roar of the crowd. Massa came up the back of Perez, making contact and causing huge impact as both cars hit the wall. Both drivers are ok despite the crash looking particularly nasty.
This meant that Ricciardo won the race with the safety car, with Rosberg coming in second and Vettel in third, while Jenson Button took fourth and Nico Hulkenberg came fifth.
The win was big for Red Bull who are hoping to gain on Mercedes who held a considerable lead in the Constructor's Championship standings. Team boss Christian Horner said after the race: "It was an incredible drive. It's been a great team effort. We beat them (Mercedes) at the most unlikely track. We are closing the gap."
On taking the podium for the first time and becoming the fourth Australian to win a Grand Prix after Jack Brabham, Alan Jones and Mark Webber, Ricciardo said: "I am still a bit in shock. Thanks everyone. This is ridiculous. There are lots of Australian flags, which is nice. The race really came to life for the last 15-20 laps.
"Hamilton had a problem and Rosberg was slow down the straights. I really struggled to get past Perez but managed to finally get a run out of the last chicane and get a nice run out of turn one and set my sights on Nico with couple of laps to go. I finally managed to get in the right spot to use DRS and it's an amazing feeling right now."
Meanwhile Mercedes, who will have been left disappointed after having dominated first place in the first half of the season, reported that "high-voltage control electronics failure led to a permanent loss of MGU-K drive on both cars in today's race."
Rosberg said the problem with his car occured in the pitstop, telling reporters: "We had a problem at the pit stop and that is why I dropped behind. Then I lost a lot of power in the straights but it did not quite work out. I couldn't hold off Daniel Ricciardo."
