2025/2026 Hybrid Powerunit speculation

I have no idea if there's any connection to Red Bull. I was just curious if it's something that a team would do. IIf you were going to cut the fuel, then you should harvest for a split second instead. I also wonder how well the FIA sensors detect short burst of current and/or torque spikes. There could be recoverable energy hidden in the "noise".

During a full throttle shift, ICE torque would be similar to maximum GUK torque so it wouldn't slow the ICE quickly enough. Easily solved of course - just skip a few injection events to reduce ICE torque and fuel use enough for the GUK to match revs while the shift gets done. (Firings skipped need not be consecutive.)

Interesting onboard of Lando's fastest lap yesterday:

• On the right border of the steering-wheel display you can see the SoC of the ES - although I am pretty sure that the maximum value is not 4 MJ!
• Above the gear number, you can see indicators for deployment and recovery. Also nicely shows how full deployment is mostly right out of corners, sloping down under full-throttle. This scale might also not simply be -350/+350 KW but rather a min/max of what is possible in the given situation.

I'm sure this isn't the best place to ask this but.... with so much electrical power going to the cars, will they be able to self start if stalled? Almost as if the were never stalled?

Yes, for some time now these have been self-starters. They routinely queue in the pit-lane and switch off during qualifying sessions.

In fact they now even have to start with the MGU-K at all times:

C5.15 Starting the engine
The car must be fired up with its on-board system (MGU-K) at any time.

A lot of clipping going on there eg 20 - 22 seconds into the lap - much lower rpm than the previous straight.

Can really see the superclipping in this video. This might be bad news for one particular user.
