It's unfortunate that we have some members now outrightly lying and name calling drivers and team personnel on this forum that has maintained certain decorum.

Honestly. It's been ONE race.
This forum I thought was for proper technical discussion. Engineering, power units, aerodynamics, race strategy, telemetry.

Instead I constantly see ad hominem attacks against drivers and TPs for...taking their competition seriously? For doing everything possible to preserve their advantage into a brand new regset, as is their job?

Holy Drive to Survive, Batman, I might as well go back to Reddit.

Hi guys, here is my take on the lap around Albert Park.
I've made a lap time optimizer with hybrid power train to analyze harvesting/deployment patterns:
https://x.com/m_lubieniecki/status/2031433586226700426

Interestingly, the optimiser only harvests about 4.5 MJ out of the 7 MJ allowed per lap. I’m curious whether this also happens in reality, or if this is just a modelling artefact.

AR3-GP use the data from the race (visible on the screen) to plot the recharge amounts - he got about 7.7 and 7.3 MJ as recharged amount by Norris and Verstappen in that lap. Worth a look.

What is the reference lap you are using? Is this optimized for qualifying or the race

Field spread is enormous.

As a separate but related point: I also don’t understand why they didn’t design these regs so batteries could be charged in the garage/on the grid (as you would for a plug in hybrid at home). It would save a lot of hassle with out laps (and extra charge laps) wouldn’t it?

For safety reasons, batteries must be discharged in the pits as indicated by the specific status light.

I believe the charging regulations for the formation lap could be adjusted, allowing the engine to be used beyond the limits set for the race in order to recharge the battery.

Hi, thanks for reference. This is a qualifying simulation. If they harvest less than possible during the race, it might be also happening in qualifying, especially where you can start with full battery and empty it before the end of the lap. I will try a race lap and see if I can get close to the 7MJs derived in the post. I might be also overestimating ICE and harvesting efficiency, but there's no data really so I have to guess.

What prevents them from charging constantly on the completely part throttle warm-up lap?

Is this performance per kg or performance per second. Perhaps cubic performance. Cadillac are in a good position for a new team though, having 4.770% more performance than Mercedes. 4.770 does seem like a reasonable estimate. 4.771 and I'd have said it's a bridge too far.

They go full throttle on the warmup lap to carry speed through the corners to warm the tires. This drains the battery again.

This would be like the closest field in history if we compare to like 1990! lol

Bright side and all that.

Basically when your axles and wheels are turning, the energy you get back from them when braking can go into either:
- warming up the tyres
- warning up the brake plates
- back into the MGUK to charge the battery

If you mess up that energy balance/harvesting you might end up with optimally warmed tyres/brakes but an uncharged battery, which is what happened to everyone. It just happened to hit Ferrari less bad than Merc/RB apparently.

A post above the one I linked, there is a full lap by Russell with data showing when he is charging, deploying, etc. What surprised me was that there was a lot of partial deploying. Could help with your analysis.

How real is it though? I thought the teams don't share battery states. Are they sharing deployment levels then?

It's not up to the teams. All of the telemetry is sent to the FIA. FIA needs to monitor these parameters to make sure teams are not exceeding power and energy limits. That's how it ends up in the broadcast.
