01
Does the battery cost tyres?
Silverstone 2026. The belief: push hard on the straights, pay later in the tyres.
02
Nobody can see the battery.
F1 publishes speed and throttle, not charge. So I read it from its footprints.
03
76% of runs stalled.
Flat out, yet no faster: the battery had run dry. 4.1 seconds on the pit straight.
04
90 stints, one test.
If deployment cost tyres, the dots would climb to the right.
05
r = −0.04.
No relationship. The belief does not survive the data.
06
The trap.
Sprint: r = −0.55. Race: r = +0.21. Small samples, opposite stories.
07
It decided speed, not tyres.
Gain over the teammate, same car, end of the straights.
08
How the weekend went.
Antonelli won the Sprint, passing on the Hangar Straight. A broken part ended his race. Leclerc won.

What I take from it.
Energy is about driving and setup. Next: other circuits. Battery figures are inferred, not measured.
