Mercedes technical director James Allison says the team has “understood” most of the risk areas behind its “very painful” reliability failures, with the issues linked to the battery and fixes set to be introduced as the season progresses. Allison said: "I think anyone who's a keen watcher of the sport will have seen that this has laid a few Mercedes engine cars low over the season so far. They're not all identical, but they do sort of originate in the same broad part of the battery. And I think that most of the areas of risk have been understood and, with a bit of luck, when we start to phase in the new modules into the racing season, then our fortunes as a fleet should pick up. These DNFs are very, very painful."

George Russell said Mercedes dropped its Right of Review bid over his Monaco Grand Prix penalties because it “did not have a case”, leaving his 12th-place result unchanged. Mercedes had filed the request after Pierre Gasly’s Monaco time penalties were rescinded, but withdrew it days later. Russell wrote on Instagram: “Having looked at every single possibility with the team to overturn the penalty from Monaco, unfortunately we did not have a case.” Mercedes added that pursuing the review “will not serve our team or the sport”.
Kimi Antonelli says Mercedes need to improve reliability after he retired from the Barcelona-Catalunya Grand Prix with a battery problem, describing the setback as a “bump in the road”. Antonelli said: "Of course, it's very disappointing, but these things happen. It happened to George in Canada; it happened to me this time. It's definitely something we need to work on as a team, because it's important points that we lost."



Lewis Hamilton says “innovation” will be key if Ferrari are to stop Mercedes “running away” with the championship, after his first victory as a Ferrari driver at the Barcelona-Catalunya Grand Prix. Hamilton said: "It's so early in the season to get to this point. These guys have really listened and really worked hard to add performance and be innovative. This year is all about innovation. This is what I was asking for last year. It was like this team has to be the leaders in that, and they've shown that they can and they will."

Toto Wolff says Mercedes will “leave no stone unturned” to understand and fix its recent power unit failures after Kimi Antonelli retired from second place at the Barcelona-Catalunya Grand Prix with what the team called an “electrical shutdown”. Wolff said: "We can't DNF cars in a regular, continued way. Losing 25 points in the constructors' championship in Montreal, and losing another 18 points [in Barcelona], in order to finish first, first you must finish - and reliability, this is what we need to get on top of. That is number one, and nobody is happy about it, and we will leave no stone unturned to understand [what is causing the issues]."

McLaren team principal Andrea Stella said Lewis Hamilton would have won the Barcelona-Catalunya Grand Prix even without the virtual safety car, as he questioned whether McLaren should have tried a three-stop strategy for Lando Norris. Stella said: "If anything, the question in hindsight is whether we should have gone for a three-stop strategy. What was the right strategy? At one stage, when we saw that the hard tyres were performing well in the second stint, we thought the two-stop would be a way, at least, to try to limit Hamilton. But, as a matter of fact, Hamilton was fast—probably the fastest car out there—and I think he would have won anyway."

Red Bull boss Laurent Mekies says Formula 1 needs “extreme certainty” in how it assesses the internal combustion engine pecking order before the FIA formally declares its findings on the awarding of ADUO. Mekies said: "Certainly, you will need to have extreme certainty in the way you are assessing the ICE pecking order. That is in order to have the right confidence to give it to the dominant team, and not to the team that is chasing the dominant team, especially when you get relative performance variations from track layout to track layout, that are perfectly consistent with ICE power sensitivity."




Lando Norris says he still believes McLaren can win races and keep its title defence alive despite a winless start to the 2026 season and a run of reliability-related retirements. Norris said: "I still believe we can win; we should have won in Miami, we could have won a race this year just on pure pace, and because we would have deserved it. That still gives me plenty of hope, not considering how far off we were at the beginning of the year. I think it's just the DNFs, the [lack of] reliability we've had, which has just hurt a lot. I don't think the title is impossible."

Williams team principal James Vowles says he is confident Alex Albon and Carlos Sainz want to stay with the team next season and would tell him if they were considering other Formula 1 options. Vowles said: "Because we have the same values in that honesty and transparency, it means that if they are considering anything else, they come to me and talk to me about it. At the moment, Carlos and Alex want their future to be here."

Sergio Perez says Cadillac are bringing a “big package” of upgrades to the Austrian Grand Prix in the hope it will move them into the Formula 1 midfield fight, with the team still yet to score a point this season. Perez said: "It's good information for the team. We just have to make sure that we are able to come out on top, and we are bringing a big package for Austria. I hope that will bring us into the midfield group."




Toto Wolff says Mercedes need to discuss with George Russell and Kimi Antonelli how they race each other, after their battle at the Barcelona-Catalunya Grand Prix cost the team lap time as they fought Lewis Hamilton. Wolff said: "They raced each other quite hard before George's stop and I think we lost four, five, six seconds to Lewis, and then obviously with the VSC, it changed the order. We tried to race fair in the team game but maybe it cost us the win today and that's something we need to discuss with the drivers, how are we doing it if we're fighting somebody else for a race win."

Mercedes deputy team principal Bradley Lord said a problem during George Russell’s final pit stop left him with an oversteery car and “compromised” his pace in the closing stages of the Barcelona Grand Prix. Bradley Lord said: "It was great to see George, after a difficult run of results in the last few Grands Prix, back at his best, taking pole, and fighting for the race win. Doing that also, notwithstanding the fact that in our final pit stop we actually incorrectly adjusted the front wing, owing to a problem with the adjuster gun, and that meant he was driving with a very, very oversteery balance that certainly compromised his pace in the final stages."
Carlos Sainz says he is weighing up how long he is willing to wait to win again in Formula 1 as Williams struggles for results this season. Sainz said: "It's something I'm working on, also in my head, how long I'm willing to wait to win again in Formula 1. I want that time to be as short as possible."



Carlos Sainz says Williams need to “go back to the drawing board” after what he described as a “realisation” in Barcelona about how far off they are in medium- and high-speed corners. Sainz said: "Looking back at it, I think it was a bit of a shock how far [off] we are in medium and high-speed corners. Partly, it's due to weight, but even more importantly, it's downforce in the car. So I think it was a massive - I don't want to call it a shock, not even a wake-up call, because we knew it, but a realisation that we are really far from where we should be."

Haas driver Oliver Bearman says moving to Italy as a teenager to join the Ferrari Driver Academy, and the structure the team provided, helped him mature quickly. Bearman said: "But I had to mature and grow up very quickly. I was also surrounded by adults all the time: engineers, mechanics, sometimes other drivers, but mainly my trainer. So, I just had to mature to that level because those were the types of people I was spending my time with. It was very crazy, in a good way. That move and the structure that Ferrari gave me really disciplined me into the person I am today."
