Mercedes arrives at Silverstone with high hopes of repeating past glories, but as the 2025 Formula 1 British Grand Prix weekend unfolds, it is clear that the weather is holding the keys to their fate. George Russell made no secret of his frustration after Friday practice, explaining that fluctuating track temperatures could make or break the team’s race ambitions.
After a memorable victory for Lewis Hamilton last year, Silverstone should be a source of confidence for Mercedes. However, a closer look at this weekend’s early action reveals the team is fighting not just their rivals, but the elements themselves.
Track temperatures pushing toward 40 degrees exposed a nagging issue for Mercedes: rear tyre overheating, which chipped away at their performance on both short and long runs during FP1 and FP2.
“It’s a little bit frustrating for us that every single week we are at the mercy of the weather, and we need to improve that,” said Russell. “Especially now we’re entering the summer months, we’re doing everything we can to improve it.”
As Russell explained, “After [Friday], it’s not very close, but it’s been a bit warmer. The track was 40 degrees, and I hope the rest of the weekend it cools down.”
Cloudy Skies Could Tip the Balance
Despite being one of the most successful teams in recent F1 history, Mercedes continues to grapple with temperature-sensitive performance. The forecast for cooler, cloudier weather offers a lifeline.

“I think our fortunes will turn slightly for the rest of the weekend, and it will come towards us,” Russell continued. “But as I said, we can’t be at the mercy of the weather, and we are right now.”
The British driver, still riding high after a win in Canada, believes the expected drop in temperature could play to the team’s strengths. Yet, it is an uncomfortable position for any title contender.
“If it’s wet in qualifying, definitely excited for that,” Russell added. “The wet tyre is a bit of a unique one, because the wet tyres actually deg more than dry tyres.
“So actually, it’s all a bit… I don’t want to get too bulked up in the details here, but actually a wet race probably wouldn’t be ideal. But if we just wanted it nice and cold and dry, it would be ideal.”
While Mercedes hopes for relief from the British summer sun, their rivals are thriving. Russell noted: “Ferrari have really turned it up for the last couple of races. They’ve been strong in race pace all season really, but they’ve been having bad qualifyings.
“But I think now that we’re entering summer, everyone’s overheating a little bit more, and we’ve really taken a step backwards, and they’ve taken a step forward purely because of the temperature.”
Ferrari’s Gains Highlight Mercedes’ Plight
The shift in fortunes has not gone unnoticed in the paddock. With the championship moving into the heart of summer, the Italian team has capitalised on rising track temperatures, finding the sweet spot that Mercedes still chases.
Meanwhile, the Brackley squad is left hoping for the famous Silverstone clouds to make an appearance.
Russell is candid about the challenge. “It’s frustrating for us that our entire performance is dictated by the forecast. We have to make sure that’s not the case if we want to compete at the very top. We’re working hard behind the scenes to fix it, but it’s an ongoing process.”
Qualifying and the race remain ahead, and Mercedes’ prospects could change quickly if the weather cooperates. But for now, the team’s hopes rest as much on the British climate as on the talents of their drivers and engineers.
