Key Highlights
- Lando Norris secured a commanding victory for McLaren at the Sao Paulo Grand Prix, overcoming treacherous mixed conditions at Interlagos.
- McLaren Team Principal Andrea Stella credited cooler track temperatures and Norris’s exceptional driver adaptability for unlocking the pace of the MCL40.
- The triumph validates recent car development and Interlagos upgrades, providing a strong platform ahead of further updates arriving in Las Vegas.
Tyre Temperature Management and Cold Weather Favor the MCL40
The Sao Paulo Grand Prix transformed into a relentless strategic battle dictated by operating windows and fluctuating grip levels. Competitors navigated the unpredictable Brazilian climate using intermediate compounds at both the beginning and conclusion of the race, interspersed with a critical stint on soft slick tyres. Lando Norris and the McLaren Formula 1 Team managed the complex variables more effectively than the rest of the field, earning an impressive victory at Interlagos.
Following the race, McLaren Team Principal Andrea Stella acknowledged that the unseasonably cool Sunday weather proved pivotal in mitigating the car’s known weaknesses regarding heat degradation. Stella addressed the environmental factors that shaped their performance profile:
“My explanation of our performance in dry today is associated with the track and ambient temperature,” said the Italian post-race.
“The conditions were very cold, much colder than we had in practice. In practice, I think we saw that we were still tending to overheat the tyres. Today, somehow the conditions came our way, and we could keep the tyre temperature under control. I think that’s the main reason.
“We know that we have some work to do in terms of getting more consistent in long runs in hot conditions, and I think we were in a way helped.“You could see also this well, especially with Lando, when the track was getting greasy before switching onto intermediate tyres. Lando was just able to keep the lap times much better than anybody else, and I think our car is good from this point of view.”
Fluctuating Pace, Strategic Decisions, and Driver Adaptability
The race order experienced multiple shifts across changing track surfaces. While Norris faced initial challenges warming up his rubber, other competitors capitalized on the cold opening tour before the McLaren driver established control as the race unfolded.
“I think what we have seen is that cars exhibited different features,” he said. “Like at the start of the race, you needed to be good at bringing the tyres into temperature.

“In the laps to the grid, nobody could actually generate any temperature. So definitely, in the early laps, there was a premium to the cars, or the drivers, that were able to generate tyre temperature.
“Obviously Max [Verstappen], likewise Lewis [Hamilton], I think they have shown their talent not only from a tyre switching on point of view, but also in the first lap. I watched some images; they were just incredible how easily they gained positions.“But going back to the evolution of the race, I think something we have seen [Saturday], even in Qualifying, we seemed to be good when there was a lot of water, and then we kind of lost it a little bit in Q2 when there was less water.
“Likewise today, it was difficult to see a car that was good in all conditions. We struggled a bit more with Lando at the start, and then somehow we managed to keep good grip in the intermediate tyres, and also on the soft tyres.
“I think in the final part of the stint on the soft tyres, Lando was very fast, and probably there he is the one that had done the best job. Because if you look at [Kimi] Antonelli as well, he was good at the final part of the stint on soft, and he struggled at the start, and he lost position.
“So, it was technically a very interesting race, because really everyone had to deal at some stage with the tyres being either too cold or getting too hot, but without a clear pattern. All teams will have some data to look into, and understand.”
During the middle phase of the Grand Prix, pit walls assessed whether it was feasible to extend the soft slick stint to the finish. However, aggressive pit strategies forced contenders to take a measured approach rather than gambling on extreme tyre life.
“Antonelli decided to go for another stop, and this made our life a little easier from this point of view,” said Stella. “I don’t think at any stage we thought that we could have gone all the way to the end.
“Russell, I think, is the only one that took advantage for staying on the same set and going on to intermediate tyres. This was a consideration, but we were unsure as to how the rain would have actually manifested itself. So we decided with both drivers to go for the more rational approach, which was just go on another set.”
Stella went on to highlight Norris’s instinct when grip levels diminish, noting the young British driver’s ability to extract lap time when the balance of the chassis is compromised:
“You’re never going to have a really perfect car, you’re never going to have the perfect conditions,” said Stella. “So adaptability is actually probably the most important feature that you may want to possess as a driver.
“I think that should be definitely acknowledged and recognised for Lando, when there’s a need to understand what’s best, how to operate, he is definitely a master.
“Hopefully we don’t need to rely on these qualities though, we just want to make sure that we can offer Lando and Oscar [Piastri] a competitive car such that they can just drive a little bit more easily, because still our car remains pretty difficult.”
Why This Matters
Having previously secured victories during the summer at the Hungaroring and Zandvoort, and suffering a near-miss in Madrid due to a Virtual Safety Car period, McLaren had witnessed rival outfits respond with their own performance enhancements. Returning to the top step of the podium in the closing phase of the calendar confirms that recent technical revisions are yielding trackside gains.
The performance at Interlagos validates McLaren’s latest upgrade package, representing an early development foundation aimed toward their 2027 design that was fast-tracked into the current campaign.
“As for the McLaren trajectory, after the upgrades in Hungary, it was encouraging that we were in position to win,” said Stella. “We should have won Madrid, really. But after that, other people took upgrades, and we lost this position. I think we also paid the price on not having had great Qualifying sessions.
“It would have been interesting to see Lando starting from the front in races like Austin or Mexico. I think it would have been definitely a fight for podium, but it’s thanks to these upgrades that we are now in condition to fight for the victory, combined with the conditions surely.”
Looking ahead, McLaren plans to introduce additional aerodynamic and mechanical components at the next round in Las Vegas, further solidifying their race operations and technical baseline.
“And these upgrades, first of all, they will be complemented by some more parts that come in Vegas, and they form the foundation for what will be next year’s car.
“So it’s encouraging for the trajectory of McLaren that we seem to be able to transform our development into performance on track, and it’s also important for McLaren that we had solid pit stops because we don’t come from a period of consistent pit stops, and also execution in these mixed conditions.
“Because we have had some disappointing races, like in Canada, where we were starting with the intermediate tyres, and the double extra formation lap was unlucky, honestly.
“So it’s good that we were able to master these conditions at the pit wall as well. And I’m very proud to have seen the team operate at this very high level.”
Frequently Asked Questions
Why was McLaren so fast in the dry during the Sao Paulo Grand Prix?
According to Team Principal Andrea Stella, the drop in track and ambient temperatures played directly to McLaren’s strengths. Cooler conditions prevented the MCL40 from overheating its tyres, a vulnerability that had surfaced during warmer practice sessions earlier in the weekend.
Could Lando Norris have completed the race without his final pit stop?
While McLaren and Norris discussed running their soft slicks to the end, the team determined it was too risky given the uncertain arrival of rain. Once rival drivers such as Kimi Antonelli pitted for fresh tyres and demonstrated strong pace, McLaren opted for the safer, rational strategy of pitting both Norris and Oscar Piastri.
What does this victory mean for McLaren’s future upgrades?
The win confirms the effectiveness of McLaren’s fast-tracked Interlagos technical package. Stella confirmed that additional development parts will arrive for the Las Vegas event, serving as the developmental foundation for the team’s upcoming Formula 1 car designs.
