Monza Prepares for 2026 F1 Changes: A New Energy Challenge

Monza is used to excess. Noise, speed, risk – all turned up to 11.

This weekend, it hosts something very different: Formula 1’s 2026 cars arriving at the sport’s fastest circuit with not enough energy to properly stretch their legs. Drivers are already warning that the experience will be “weird”, “confusing” and “not fantastic”.

The Temple of Speed is about to watch cars that can’t quite live up to the name.

Monza, but not as we know it

When teams first ran the 2026 regulations in the simulator, Monza lit up the alarm systems. The track that usually exposes drag and power suddenly exposed something more fundamental – a lack of usable energy.

Early models painted a bizarre picture: cars rocketing out of the chicanes, then haemorrhaging speed halfway down the straights as the battery ran dry. Some simulations even had drivers dropping gears on the straights just to keep the power unit in its operating window.

Regulation tweaks since then – reduced recharge limits and capped deployment – have changed the shape of that problem. The dramatic 30–40km/h drop-offs from the old 350–360km/h peaks should be gone.

But so are the peaks themselves.

Instead of soaring and then falling away, the 2026 cars are expected to level off, never getting close to the top speeds Monza once guaranteed.

As Racing Bulls rookie Arvid Lindblad put it: “There's just not much battery. We don't actually go slower on the straights. We just don't use any.” The throttle stays down, but the electrical shove simply isn’t there.

McLaren’s Oscar Piastri has already seen the consequences on the simulator. They are as counterintuitive as they are damning for Monza’s aura.

“I think in our sim running we were actually quicker on the front straight in Hungary than we were here,” he said. “It doesn't make a whole lot of sense, but it's more that we just don't have the energy to spend.”

So the sightlines stay the same. The braking boards, the grandstands, the trees flashing by. The stopwatch will tell a different story.

Sim data suggests drivers won’t need to downshift on the main straight into the first chicane anymore, but they might be forced to slip into seventh on the uphill run to Ascari. A gear change there, in what used to be a flat-out blast, underlines how different this Monza will feel.

No “super-clipping” spectacle killer

One major fear heading into the weekend was that teams would be forced into extreme “super clipping” – heavy harvesting that slashes straight-line speed – just to survive an energy-starved lap. That would have turned the Lesmos and Ascari into glorified recharge points rather than the high-commitment corners they’re meant to be.

The FIA’s 5MJ harvesting limit for Monza has pulled that scenario back from the brink. Teams simply don’t have enough harvesting capacity to go wild with super clipping, even if they wanted to.

Piastri spelled it out clearly: “If the harvest limit was higher, we would be super clipping everywhere, probably losing 30 or 40 km/h at the end of each straight, but with the [5MJ] harvest limit, the super clipping is a normalish amount, or a reasonable amount.”

So the cars won’t be crawling to the braking zones. The trade-off is more subtle: less energy to spend, less speed to chase, and a lap that looks familiar but feels strangely muted from behind the wheel.

No clever hacks this time

Across 2026, drivers have learned to game the new energy landscape. At tracks like Spa, the fastest way around often meant slowing down in the corners – easing off in once-flat sections like Pouhon, or short-shifting on exit – to bank extra energy for the straights.

It was counterintuitive, but it worked. Go slow to go fast.

Monza, though, doesn’t seem to offer that kind of trickery.

Lando Norris laid out the problem in simple terms. “I think the difference to Spa was that you had two big straights but you had lots of corners in-between that you could charge up and then deploy everything.

“Unfortunately here you have two long straights back-to-back, but even between them there's not really any corners. So, there's just no energy, there's just no power. You don't have an ability to charge, so it's just slow.”

There are fewer places to lift, fewer braking zones to harvest from, and less room to play the energy-management chess game drivers enjoyed at other circuits. Monza strips the lap bare. If the battery’s empty, it’s empty.

Out-laps, cool-downs and the strange new rhythm

The key to a quick lap this weekend will be simple on paper and fiendish in practice: arrive at Turn 1 with the battery in the best possible state of charge.

That doesn’t just affect the flying lap. It reshapes everything around it.

For out-laps, F1 has set a 9MJ recharge limit. Combine that with the need to fire tyre temperatures into the right window and there’s at least a reason to keep moving with some intent. Trundle too slowly and the tyres die before the lap even begins.

Cool-down laps are a different story. They’re capped at 5MJ, the standard limit. So if a driver runs a push–cool–push sequence in qualifying, that middle lap could become painfully slow as they tiptoe around the limit, trying not to overcharge too early and hit the ceiling before they’re ready.

Lindblad expects that to be one of the least enjoyable parts of the weekend.

“I think the out-laps will be slow, but I don't think they'll be stupid,” he said. “I think what won't be enjoyable is going to be cooldown laps, because the rules are different between out-laps and cool laps. So, in cool laps you'll be going very slow to try to charge the battery.”

Fans are used to Monza qualifying as a chaotic slipstream lottery. This time, they might also see cars crawling in unexpected places, drivers juggling tyre temperatures, traffic and a stubbornly finite battery.

The start-line trap at Parabolica

Then comes one of the trickiest puzzles of all: how to start a lap.

Use too much deployment out of Parabolica to boost top speed across the line, and the car can arrive at the back straight short of energy. Save too much, and the lap begins with a whimper.

Earlier in the year, drivers had to decide for themselves where to squeeze the throttle fully before the line, creating a game of cat and mouse that made it hard to predict who was genuinely on a lap and who was simply preparing.

In May, a package of in-season tweaks brought in an automated solution: ‘auto-K’. Teams now program where the battery kicks in, and the system handles deployment in pre-defined zones.

At Monza, the exit of Parabolica is one of those zones. Drivers will leave the corner flat on the throttle, but the battery will only wake up when the software says so. That could create some huge speed differentials between a car ending its lap and another just about to start one.

Lindblad has already seen a version of that problem.

“We saw it a bit in Zandvoort, but it was okay because of the banking,” he said. “There was a 50-60 km/h speed delta, so you could get out of the way and let the guys through.

“Here it's even more - and it could become a bit dangerous. So, starting the lap won't be easy, to have it full, have the tyres ready.

“But even just from traffic, from safety, it's not great. We need a better battery.”

That’s the nub of Monza 2026: a circuit built to celebrate power, hosting cars that are constantly managing scarcity. The track hasn’t changed. The demands on the technology have. And as the drivers keep reminding anyone who will listen, the sport’s most famous straight might now be the place where F1’s new era looks – and feels – strangely short of breath.
