It was Max Verstappen who first sounded the alarm, warning that “Silverstone will be a completely different circuit.” Now, on Thursday ahead of the British Grand Prix, Fernando Alonso has reinforced the Dutchman’s concerns, suggesting that the layout of the iconic British track could expose one of the biggest weaknesses of the 2026 Formula 1 cars.
The fear is that one of the most spectacular and beloved circuits on the calendar could lose much of its appeal because of the significant limitations imposed by the architecture of the current hybrid power units. But why is Silverstone expected to present such a challenge?
Alonso: “Without battery power, we’re slower than Formula 2”
“It won’t be fun,” Fernando Alonso admitted bluntly. “I think it will be very different compared to the past. It will be sad, both for us and for the fans.”
The concern is easy to understand. From Luffield, Turn 7, all the way to the braking zone for the Vale chicane at Turn 15, there are virtually no heavy braking points. In practical terms, that means drivers will spend between 35 and 40 seconds without meaningful opportunities to recharge the battery, creating a situation similar to what teams already experienced earlier this season in Australia.
To make matters even more challenging, recent regulatory adjustments have reduced the available energy deployment limit to 6 MJ, making efficient energy management even more critical. The outlook, therefore, is far from encouraging.
According to Alonso, even two of Silverstone’s most iconic corners—Copse and the Maggotts-Becketts sequence—will effectively become “charging stations.”
“The effect will be even more noticeable in the corners because losing speed through a corner feels much worse than losing speed on a straight,” Alonso explained. “You approach those sections thinking of them as incredibly fast corners where you experience huge lateral forces and have to push to the absolute limit. Now, instead, they’ll be much slower.”
The Spaniard also warned that the problem will not be limited to Silverstone. In his view, the following round at Spa-Francorchamps could expose similar limitations because of its high-speed nature and long periods spent at full throttle.
“They’ll be circuits where energy management becomes extremely delicate. You can’t use full power on every straight. If you use all your energy from Turn 1 to Turn 5 at Spa, you’ll have nothing left for the rest of the lap.”
It will nevertheless be fascinating to see how each Formula 1 team approaches the challenge, with engineers expected to adopt different hybrid deployment strategies in an attempt to optimise performance around these demanding circuits.
Despite those possible variations, Alonso believes one fact cannot be ignored.
“The reality is that once the battery is depleted, we have less power than a Formula 2 car. Unfortunately, that’s simply the way it is.”
