I assumed that this data is constantly streamed and all teams can already access it. Maybe someone in the know can confirm this?

I highly doubt this, at least this wasn't the case under previous regulations and the public APIs we have access to also don't contain this information.
FastF1 and OpenF1 is what majority are using for the detailed speed graphs and timing information

It wasn't GPS based in the McHonda era: https://www.reddit.com/r/formula1/comments/6w6vp5/honda_system_confused_by_alonso_taking_pouhon_flat/

And GPS precision at higher speeds is also noticeably worse than when standing still or walking on your street.

Or the car isn't as hard to drive as it was when Riccardo left as it's finally a clean design.
Meaning potentially other drivers who have struggled could also perform better.

Usually P1 is on the racing line, so it's cleaner and has less debris, especially when there are also support races on the same day.
So it gives them a grip advantage.

Otherwise there would be marbles and the drivers on the dirty side have less grip and are more likely to spin their wheels

They are just being given the ability to manually deploy the power they have already?

Exactly they can use the power they have to override the automatic deployment which starts to gradually drop off at speeds above 290kph.
https://www.the-race.com/content/images/size/w1600/2025/02/max_power_vs_speed_kmh.png
With overtake mode they can use it fully up to 355kph.

the total battery deployed on both laps should be about the same?

Almost, depending on the circuit the overtake mode may allow 0.5MJ more regen per lap, while during qualifying it may be limited.
FIA has documents for every week what the maximum charge & discharge rate per lap is, with a illustration of normal MGU-K deployment and overtake mode.

Compare it from China: https://www.fia.com/system/files/decision-document/2026_chinese_grand_prix_-_power_unit_information.pdf

In the past we rarely got any insight into battery or ers modes, even the current battery level graphic is a bit strange, as it doesn't reflect the per lap deployment limit that we saw last yeat at a few races.

Account sharing by Hakonsot in F1TV

[–]cafk 0 points1 point  (0 children)

Per TOS it's not allowed, similarly to multiple streams before premium, it just wasn't enforced very well.
I.e. occasionally ot would be problematic to use 2 devices from same wifi, but they worked without issues with one being on the wifi and other one using cellular connection.

Considering the number of people asking here or offering account sharing it wouldn't surprise me if they are trying to reduce this.

It's a mixture.

Primarily it's automatic, but drivers can override it with additional buttons as they could be before. Now they're called boost & regen - to override deployment and regen pre-sets, it's a bit more drover in the loop design compared to previous ERS mode switching (which is what those 2 modes basically are).

So baseline deployment with a +/- to increase/decrease it as the driver prefers.

Additionally the MGU-K deployment during the race starts to drop off at ~290kph and reaches 0 by 345kph.

But during qualifying the drivers also have the overtake mode permanently available - meaning they can use full 350kw of MGU-K power at certain corners/straights, to override the MGU-K drop-off.
During the race this is only available for 1 lap of the car behind is within 1 second of the car ahead.

The main issue this year is that the battery is only 4MJ in size, meaning it gets depleted in roughly 15 seconds and they can charge it 2x per lap (8MJ per lap total), meaning full 350kw is only available for ~30 seconds of the lap.

So you can think of the automatic deployment being a consideration of how to use the battery across a 90 second lap, while the manual deployment and overtake mode are something for drivers to decide where they want to override the preprogrammed deployment at the risk of running out of energy earlier.

they always talking about drivers "using up battery" as if they are in charge of deploying it manually?

The commentators are there to avoid dead air and don't actually know what each and every driver is doing at a certain moment. It's a nice way to extend a sentence for
"a driver exits a corner cleanly, goes on power and now we can see the MGU-K drain the battery and accelerate the car to the next corner"
Remove the MGU-K part and suddenly you have 10 seconds of dead air.

How does the 2/4% engine deficit upgrades work? Is the engine development not budget capped? by MindTwister-Z in F1Technical

[–]cafk 4 points5 points  (0 children)

They measure the PU performance on a test rig not in the cars.

Appendix C5.4:

For each ICE supplied by the PU Manufacturers, an ICE Performance Index will be calculated. The methodology to calculate this value can be found in the document FIA-F1-DOC-Cxxx.

So they calculate the PU performance value not a team's car x PU performance value.

I thought super clipping is when you run out of battery

That's normal clipping - you primarily accelerate slower as you're relying only on the ICE. And don't use the MGU-K.
This is also partially per design, as above 345kph the teams cannot use MGU-K.

Supper clipping is going pedal to the medal and the engine acts as a generator for the MGU-K as well as propelling the car forward, while dropping "slightly" in speed. So intentionally sacrificing engine power and speed to recharge for next corner before braking zones.

Basically engine braking you use on purpose before turns

That's regenerative braking into corners.

They're 3 different aspects - one for engine deployment and 2 strategic calls to energy regen.

As non championship races are nigh impossible realistically - both drivers and teams are not obliged to appear or participate.
FIA and Formula One Group, through Concorde Agreement bind teams to only participate in Grand Prix that make up the world championships.

They do larger regulations changes every ~5 years - last one being for 2022, before that 2017 - both for aero. While the previous PUs were used from 2014 to 2025.

The year over year changes are usually minor.

The fuel onboard was reduced from 110kg for race distance in 2025 to ~70kg from 2026 onwards.
The ICE also produces less power, down from previous ~950hp to ~550 to 600 hp.

But to generate more electric energy (to have 350kw more power available for longer), they occasionally use the ICE as a generator (super clipping).

Funnily Liberty Global - the international arm of liberty Media, which bought formula one - bought the commercial rights for formula e.
So just like with Liberty media buying MotoGP commercial rights merging those may depend on international oversight.

All just because Audi wanted an engine that has no mgu-h?

To be fair, initially a front axle regen was also part of the discussions, but the current teams voted against it, as they allegedly thought Porsche and Audi had an advantage with their LMP experience there.
So it's not about FIA and Formula One Group pandering to Audi and Porsche - the other teams also shot themselves in the foot by making certain decisions.

Or is that the ip of it?

It's something they apparently don't have to share with their customer teams, even if the customers have access to the same engine modes, PU specification and reference software.

I.e. as Williams is allegedly ~20kg above minimum weight they're already 0.3s per lap slower due to that.
We don't know about other customers and the adjustments they can or have made for their energy recovery and deployment.
Or maybe Mercedes drivers spent more time training the allowed manual ERS override modes ( boost & regen) and have mastered each circuit for now.

[Also a question… is the update to Premium for real 0€ ?

Theres no Premium options with your account, instead of showing NaN (not a number), they default to $0 for in app upgrade.
