The best way to understand the usefulness of the PU is to do a calculation of the "Average" power output of the PU over the race distance. I suspect this is where Honda does the damage to the competition, based on what they said last season and the changes they made for this season.

I think the value of the Honda PU is being able to run higher ERS modes for longer than competitors. This gives an incredible advantage over a race distance as you have more energy to deploy in the race than the competition.
But from what I understand from Wazari-san's comments, in terms of pure ICE power, Honda is leading its competitors by 1%.
1% lead on a 100 seconds lap is one second/lap lead...
Power doesn’t scale like that to lap time. The faster you go, the less a change in percent of power makes a difference.

Remember, drag is proportional to the square of velocity. 10hp at 60mph doesn’t translate to the same speed gain at 190mph.

Is this cube term something specific to F1 cars?

My comment is just a bit wrong. Power is proportional to the cube of speed. Drag is to square velocity.

Are you being a fool? I know my math! The square root of 1 is one, the cube root of 1 is one. 1% is 1%.... :mrgreen:

Fixed Red Bull race issue?

That is of course the big question after yesterday's defect at Verstappen. "I think we'll know that around 10 p.m. tonight," Red Bull's chief engineer Paul Monaghan replied with a grin.

The defect came "unexpectedly" yesterday, he admits. You can now only "investigate" the problem as well as possible in the short time available, and later you will find out whether it has been solved.

"We have a bit of time for Australia," he says of the next race to Saudi Arabia. Monaghan does not believe that the defect has anything to do with the curbs on the street circuit.

"Right now we don't have any indication that that was really a factor," he said. At least that's what the first analysis showed. Now all Bulls fans have to keep their fingers crossed that the defect does not repeat itself.
The Power of Dreams!

I wonder if they will turn down the power unit to reduce the load. That could make it harder to overtake.

Thats nonsense. Peak torques are not engine related.

There's something else acting upon the driveshaft?

This has always been the case.

Honda documented how shaving off 12hp off peak in 2006 for some mid range was faster around Monza, of all places.

We do all sorts of torque shaping work with our engines in real life. Making a big peak number is actually relative easy (on a naturally aspirated engine. Making a good peak but with more power in your entire operating range is hard).

BUT, you need to factor drag into your energy calculations. If you add up energy deployed, you need to subtract it from energy consumed for comparative purposes, and that doesn’t even factor in turning that power consumed into downforce / grip.

If you look at terminal speeds over the last 35 years, they’re relatively the same. The current cars just take all that extra power and convert it to downforce, and that’s ultimately why they’re faster.
Emphasizing the role of aerodynamic drag is meaningless. In fact, every 10 horsepower increase in engine power can bring about a 0.2 second improvement in lap time. We all saw the effect of the additional 17 horsepower advantage that Mercedes' overboosted engine gained in 2021.
Source / data to back this up?
Sorry, I'm not sure how to upload images here, and the picture I want to use as evidence of the 2021 Brazilian Grand Prix showing Mercedes engine leading Honda by 17HP cannot be uploaded. According to the statement made by Ferrari team principal Binotto during last summer's break, an increase in engine power of 10HP results in a lap time improvement of approximately 0.2 seconds.
