2026 F1 cars Silverstone power issues exposed
Alonso, Hamilton and Verstappen all warn that iconic corners like Maggotts and Becketts will be ruined by energy shortages this weekend.
Why the 2026 F1 cars Silverstone power issues are so severe
Silverstone has long been a favourite for its fast, sweeping corners. But F1’s new regulations put nearly 50% of total power output on the car’s battery, and Silverstone’s layout is brutally unkind to that system.
The new 2026 power units are highly dependent on their batteries, and Silverstone’s many fast corners offer very few opportunities to charge them. That is the core problem.
The new generation of F1 cars are energy starved, and the layout means there is a long run from the exit of Brooklands down to Stowe with little chance to recover power. Simulator runs suggest car speeds fall away dramatically through the Becketts complex.
The biggest pain point comes when cars must cover a significant distance without the chance to harvest energy under braking. That is what led to the phenomenon of super clipping, where cars charge the battery against the engine on the straight while staying on full throttle.
We already wrote about how this could affect the sprint format this weekend. Check out our piece on why battery fears could shake the British Sprint for more detail.
Alonso and Hamilton speak out on 2026 F1 cars Silverstone power issues
Fernando Alonso was direct: “This year is going to be very different and not fun to drive the cars. Looking at the simulator laps and things like that it’s going to be quite sad, I think, for the drivers, but also for the spectators.”
Asked what Maggotts, Becketts and Chapel would feel like under the 2026 regulations, Alonso described the complex simply as “a charging station”.
He also explained the physics of why corners are worse than straights for derating: “The problem when you de-rate on the corners is also that your drag level is higher. You have the rolling resistance from the tyres turning the wheels. So you lose speed from the pure drag of the car, but you lose extra speed because you are turning the car.”
Lewis Hamilton confirmed that drivers share the same concerns. “It’s an unprecedented weekend in terms of the power deployment,” he said. “All us drivers have been talking on the drivers’ chat just how poor the power is going to be through this track.”
Hamilton added: “We run out of battery power, there’s only a few corners to charge the engine, so the [MGU-]K will be switched off for a large portion of the lap.”
Verstappen “started laughing” in the simulator
Max Verstappen raised the alarm even before arriving at Silverstone. “Silverstone, I love the track, but I did a few laps on the simulator and I just started laughing,” he said. “It felt like a different track, to be honest.”
Verstappen explained the root cause: “Because of how we generate our power nowadays, this track layout is just not suited for it. When you rely only on the ICE, you don’t have enough power. So in a lot of sections around the lap, you basically just slow down a lot.”
At Suzuka earlier this season, drivers were already losing around 50 km/h through fast corners due to energy limitations. Silverstone’s Maggotts-Becketts complex could see something similar.
Other drivers echo the concern
Haas driver Ollie Bearman summed it up well: “A lot of the tracks with the most character in the previous generation, the fast-flowing high-speed circuits now just lack reward when driving them, and that hurts a bit.”
Williams driver Alex Albon went further, saying super clipping and the lack of electrical power would make Silverstone “less special”.
Cadillac’s Sergio Perez also acknowledged the scale of the challenge: “I think it’s probably the best test we face so far, since Miami. The other circuits were not so critical with energy. I think this one is the biggest test we are facing with these new regulations so far.”
Not everyone is negative, though. Championship contender George Russell has been a rare voice of support for the 2026 rules throughout the season. He argued that what matters most is whether the fans get better racing, and doubted the energy management factor would make much difference to them.
What the FIA has done to limit the 2026 F1 cars Silverstone power issues
In a bid to avoid the worst side effects, the FIA has taken a conservative route with energy deployment limits this weekend. The deployment limit has been set to 8MJ for the race and 6.5MJ for qualifying, which is 0.5MJ lower than Barcelona.
Despite this reduction, cars will still be expected to face super clipping at the end of the longest straights, although the situation will be less severe than it would have been without the Miami rule tweaks.
official Formula 1 website, and the FIA’s technical guidance is available on the FIA regulations page.
This is one of the most debated weekends of the 2026 season so far. The fear among drivers is clear: the 2026 rules could make one of Formula 1’s fastest, most thrilling circuits feel slower, less natural and less special than it should. The track action will tell us just how bad it really is.
