Lewis Hamilton continued his dominance of the Spanish Grand Prix with a record-equalling victory as Mercedes' two-stop strategy worked a treat.

Max Verstappen passed Hamilton on Turn One in a dream start for Red Bull after the seven-time Formula One champion had been on pole for the 100th time.

Championship leader Hamilton was not to be denied a fifth consecutive win in the race at the Circuit de Barcelona-Catalunya, though, passing Verstappen on lap 60 of 66 in another masterclass from the Briton.

Mercedes' decision to pit Hamilton for a second set of medium tyres on lap 43 paid off, with Verstappen having been kept out at the front and having to settle for second place ahead of Valtteri Bottas.

Hamilton managed his tyres to perfection to extend his championship lead, as well as matching Michael Schumacher's record of six Spanish Grand Prix triumphs to make it three wins out of four this season.

A late fastest lap for Verstappen provided a small consolation but he now trails in the standings by 14 points.

Verstappen had made a brilliantly bold move to pass Hamilton on the inside, the pair coming within a whisker of making contact. Red Bull's start then got even better when Ferrari's Charles Leclerc nipped ahead of Bottas on the outside at Turn Three on the opening lap.

Verstappen retained his advantage after the safety car was deployed following Yuki Tsunoda's retirement due to a fuel pressure issue on lap eight, but a poor pit stop was a setback for the Dutchman on lap 24.

Hamilton stayed out four laps longer than his rival on the soft compounds and the Brit returned with a gap of around six seconds to make up.

The reigning champion was right on the back of Verstappen when he was called in for a second time, returning in third place behind also Bottas - who had passed Leclerc - and 23 seconds behind the leader.

Bottas allowed Hamilton to go by him on lap 52, but not before the Finn showed a reluctance to follow team orders.

Hamilton moved back in front six laps from the end, Verstappen unable to prevent him from going around the outside as the Mercedes eased away.

Lewis Hamilton is embracing the element of competition in the 2021 Formula One season after taking his 100th career pole in qualifying for the Spanish Grand Prix.

Hamilton tops the standings three races in having won two of them, victories in Bahrain and Portugal coming either side of Max Verstappen's triumph at the Emilia Romagna Grand Prix.

The seven-time world champion was involved in another tussle with his rival on Saturday, edging out the Red Bull driver to reach a notable personal milestone.

Hamilton was 0.036 seconds quicker than Verstappen at the end of Q3, with Mercedes team-mate Valtteri Bottas making up the top three 0.132s back.

The Briton is the first F1 driver to manage a century of pole positions, with his first coming back in 2007 in Canada. Racing greats Michael Schumacher (68) and Ayrton Senna (65) are second and third on the all-time list respectively.

He has managed 10 poles in five of the past six seasons, while his haul of 12 in 2016 is his best tally for a single year.

The 36-year-old has recorded 58 wins when starting from first on the grid, only failing to finish among the points on two occasions, albeit not counting for nine retirements.

And it is not only the milestone which has boosted Hamilton ahead of Sunday's showdown, but also the challenge presented by Verstappen, who sits eight points behind him in the standings.

"It's always difficult to assess in the moment but wow, I've been racing a long time and the 100 mark is something I don't think anybody and particularly me thought I would ever get to that number," Hamilton told a news conference.

"It's been so enjoyable and it's crazy that it is 100 and it felt like one of the first. That for me is even more special. There have been so many qualifying sessions, so many near misses, so many mistakes and so many moments of growth and I love how close it is between us all.

"I think that's great for the fans and I think that's exciting for me also. And also the people that are only just behind us."

For his part, Verstappen is confident he can push Hamilton all the way.

"It's difficult to predict at the moment. I think we were quite decent in the long runs but [Mercedes] looked strong," he said.

"We know that it's hard to overtake around here and to be following closely, but I'm always optimistic and positive that we can do a good job and have a good race, and I hope, of course, that it's going to be as close as today."

There was not so much joy for Verstappen's Red Bull team-mate Sergio Perez, who went spinning in Q3 and could only claim eighth.

He said: "I just felt a bit weak going into qualifying, and it was just getting worse and worse throughout.

"I had a bit of an issue with my [left] shoulder through qualifying, and I was just feeling bad, all the way through it. 

"I've been with the doctors from the team, and it should be all good for tomorrow."

Lewis Hamilton could not believe how far he has come after recording the 100th pole position of his career at the Spanish Grand Prix.

The seven-time world champion emerged triumphant from a three-way qualifying battle with Max Verstappen and Mercedes team-mate Valtteri Bottas.

Hamilton ended up 0.036 seconds clear of Verstappen, with Bottas just 0.132s behind in third as none of the drivers improved in their second runs of an entertaining Q3 session.

Charles Leclerc took an impressive fourth for Ferrari, with Sergio Perez having to settle for eighth in the second Red Bull after spinning in his first run of the top-10 shoot-out.

Hamilton was overjoyed to come out on top as he continues to pull out impressive results despite the improved pace of rivals Red Bull in 2021.

"I will always remember that one," said Hamilton, who leads the drivers' standings by eight points.

"Wow, I can't believe we are at 100 and it's really down to the men and women back at the factory who are continuously raising the bar and just never giving up.

"The support I have, it's been a dream for me to work with these guys. The journey we have been on, it has been immense.

"Who would have thought at the end of 2012 when we made the decision to partner, we'd be qualifying at 100? I feel very humble and grateful – and I am ecstatic it's like my first!"

Hamilton revealed some changes to the car ahead of qualifying had him worried throughout much of Saturday.

The Briton added: "We have been strong all weekend and I made some changes - I had a bit of anxiety about the changes.

"For qualifying, you're always trying to make the car better, but it is a bit of a gamble because you have to keep the race in mind also.

"We made the change and immediately I thought, 'This is the wrong one'. It was my call at the end, but it was really hard.

"The changes that we made, I had so much understeer, the car was being lazy and wouldn't turn corners the way I wanted. I was making small adjustments to get the car to turn.

"So that's why I was behind the whole qualifying. I was making small tweaks here and there to make pace but the first lap [in Q3] was the best lap of the session - which was great."

Verstappen – who topped a Q2 session that saw Sebastian Vettel, Lance Stroll and Pierre Gasly among the eliminated drivers - was right there with Hamilton as a thrilling title battle continued.

"It was good, to be that close, we can be happy with that," said Verstappen. "I struggled in Q1 but we sorted out the balance in Q2 which was good.

"Q3 both laps were pretty decent, the second run was a little worse. It is quite gusty.

"Second for us is very good. We know they are hard to beat around here.

"To be that close, we can be happy with that – it is a long run down to turn one on Sunday, we have to make sure we get a good start and then see if the pace is there."

Bottas, who had made Hamilton wait for his 100th pole by topping the timesheet in Portugal, was competitive once again.

"That was close," he said. "Definitely was in the battle for the pole and I think the first runs in Q3 were faster ones.

"I had snap at the apex at turn 10 and lost a tenth or so, and that's the margins of the pole. With a strong package, it's going to be a good fight between us and Red Bull on Sunday no doubt."

The closest driver to Hamilton in terms of F1 pole positions is Michael Schumacher on 68.

Hamilton now has only 29 fewer poles than the rest of the current F1 drivers combined (129), while he is seeking a sixth race win in Barcelona that would the tie record held by Schumacher.

If he does it, the Mercedes star will lead the win rankings in 16 of the 32 tracks he has raced on during his illustrious career.

Verstappen took the first of his 11 career victories in Barcelona as an 18-year-old back in 2016, becoming the youngest race winner in F1 history, though Hamilton has won each of the four editions to be held since.

Fabio Quartararo made MotoGP history at the Spanish Grand Prix after becoming the first rider to secure four consecutive pole positions at the Jerez circuit.

The 22-year-old Monster Energy Yamaha rider, who won on each of the last two occasions he clinched pole at Jerez, set an early benchmark with a time of one minute and 36.807 seconds.

He was nearly toppled from top spot by his former team-mate Franco Morbidelli, who at one point got to within 0.005 seconds of a provisional pole position. 

Frenchman Quartararo's first time ultimately would have been enough to secure pole, but he went even better with a later run.

He ended the session with a best time of one minute and 36.775 seconds to secure first spot on the front row, with a 0.057s advantage over Petronas Yamaha's Morbidelli.

"It felt really good today," Quartararo told his team's official website. "Jerez is one of the tracks that I really like. I have ridden a Yamaha four times at this track and four times I got pole position. It's quite an amazing moment, I'm really happy about this.

"But I will say that today's Q2 session was a qualifying where I was more on the limit. I thought I was going to crash in turn six and turn 13. I made a mistake in turn six, but ultimately what matters is that we got the pole position today.

"Tomorrow it's not going to be easy, but I feel prepared and that I have good potential. The medium and hard tyres are both working well, so we will use the warm-up tomorrow to decide which one we will use."

Ducati team-mates Jack Miller and Francesco Bagnaia will start in third and fourth respectively, ahead of LCR Honda rider Takaaki Nakagami in fifth.

Repsol Honda's former world champion Marc Marquez, meanwhile, put in a career-worst qualifying performance and will start Sunday’s race in 14th.
