Mercedes’ Lewis Hamilton claimed his 64th career pole position – his third in four years at the Circuit de Barcelona-Catalunya and third of the 2017 season. Ferrari’s Sebastian Vettel set the second fastest time. Valtteri Bottas will start tomorrow’s Spanish Grand Prix from P3.

Lewis Hamilton: “That was a really intense qualifying. We had to pull out every millisecond we could to take pole. We made some changes ahead of qualifying and the car felt great, so I was very happy with it. The race pace is looking good and the team has done an incredible job this weekend, as always.

“I don’t know if the guys back at the factory get tired of hearing this, but they’ve done an incredible job. To make this step forward and bring a great package for this weekend to keep us in the fight with the Ferrari, I’m so grateful to them. We’ll work as hard as we can on Sunday so that effort doesn’t go to waste.”

Sebastian Vettel: “I don’t know how the mechanics did it (a precautionary replacement of the Power Unit required an extraordinary team effort to have Vettel on track in time for Q1). It’s a lot of work to put together. I want to say a big thanks to the team.

“This morning we couldn’t do what we wanted to. We know the track and the car, and I know that it is working. In the end we could have got pole position, but I missed the apex at the chicane. I was a bit late and lost a bit of time there. But, overall, putting the car on the front row is a massive success.

“I think we worked really well. We realised that there was an issue and that we could fix it. Tomorrow, with the race rhythm, it will be fine, because when you get into the pace it is easier. A good start looks always good, so we’ll see, but I am confident for tomorrow and I always try to keep a smile”.

Valtteri Bottas: “For most of the weekend we’ve had the edge on Ferrari but in Q3 they raised their game. For me starting the day with the engine change and moving back to the old engine, I was always going to be on the back foot. I really struggled through qualifying with the rear stability of the car, so it was difficult to find a good rhythm.

“It wasn’t one of my best qualifying sessions but I’m happy with the job that the team has done. You could see Lewis was very strong and quick today. It’s a shorter run down to Turn 1 than in Sochi, but we’ve seen in the past that you can make positions from the second row. I’ve done some good things from P3 before. Everything is still wide open. We’re happy with the race pace and upbeat for tomorrow.”
