Second race of the new 3 race average approach.
Here is an attempt to understand how that might work.

• Peugeot have the highest allowed power and the lowest weight. They are at the limit of what they can get.
• Generally there is an increase in weight.
  • Alpine and Porsche have a reduction.
  • Toyota get a relative improvement to Ferrari, BMW, and Cadillac.
• Low Speed Power is up for most.
  • Notable exceptions are Porsche and Toyota.
• High speed Power has a very predictable relationship to previous speed trap data.
  • Cadillac needs a helping hand here.
  • The French cars are still considered slippery.
• It is hard to see the correlation between P/W and the changes compared to the last three races. Possibly a consequence of having only half the story.
  • Teams will see the data and model for their car, but that is not shared widely.
• In the three race average approach Ferrari still has the very poor Fuji showing impacting the calculation.
• Special notes:
  • Aston Martin are still in the new car phase with conservative adjustments.
  • Porsche have 2/3rds the upgrade penalty.

Let’s remind ourselves of the performance order from the last three races and the race that falls off the list

Imola Update

Weight

Porsche is the big winner here as their weight comes off. They are down to a -0.2% penalty for the recent upgrade.

Toyota, Alpine, and Peugeot improve relative to Ferrari, BMW and Cadillac. The last three looked the quickest in the last round (Cadillac’s averages were hurt from their dramas!)

Aston Martin still has new car BoP.

Quite a lot of opposites with power. There could be some partial offset with the high power for some (see below).
Peugeot stays with the highest power given and is now back to the minimum weight.
Toyota loses out here, with pretty much everyone else increasing.

High Speed compensation

Cadillac high speed was poor over the last three races…

·	24.6 COTA	24.7 Fuji	24.8 Bahrain	25.1 Qatar
1st	Ferrari	Ferrari	Peugeot	BMW
2nd	Alpine	Porsche	Toyota	Ferrari
3rd	Lamborghini	Alpine	Porsche	Peugeot

8th	Cadillac	Lamborghini	Lamborghini	Cadillac

…and it gets a relative increase as all others have their high speed power reduced.

The French cars are still considered slippery.

The Peugeot – Alpine relationship has swapped round Not by much, but the data here doesn’t suggest this is warranted. This could suggest the method used here to eliminate laps with drafting isn’t as detailed as the rule makers as it is a simple average of top 20% to top 60% speed trap values.

The model for adjusting the top end power remains simple. In the adjustments we see a good correlation with the speed trap data. From the above data the rule makers have effectively used the following relationship.

1% change to High Speed Power results in 0.74% change in Top Speed¹.
For Qatar this was measure as 1% power change required for 0.72%.

Pit Stop Docking Time / 40 second refueling time
No change, still the usual 40s (FIA WEC don’t publish the replenishment rate)

FWD Power Deployment Speed remains at 190kph in the dry and wet for the hybrid Hypercars.

Tables
For reference here are the BoP tables for power and weight going back to the beginning of time.

1. Simple linear fit ignores Aston Martin> relationship would be 1% power change is 0.75% with Aston included. ↩︎
