Your previous post below states it has 56.8 kWh of battery capacity, so if averaged over one hour, it could support about 60 HP (assuming around 80% efficiency). Granted, on a track there would be regeneration involved, but 1,400 HP wouldn’t be possible for very long. Not on 56.8 kWh of battery.
I was joking before about a 1/4 mile run as all-out range, but numbers suggests a few minutes at 1,400 HP at most. And that assumes batteries and other components don’t overheat first.

You're assuming that its running/using 100% of the power all the time--it isn't.
(Officially its listed as 1400 peak horsepower--even the spec says it isn't running that all the time.)
Its using seven of these guys:

Peak power @ 700Vdc is 160kW so 7 of them is 1120kW! LOL
Continuous power is 20kW to 100kW.
Also keep in mind that "on the track" doesn't mean racing, this guy is a demonstrator for the likes of Ken Block...they aren't racing it, they're drifting it, sliding it, doughnuts, etc. basically doing everything they can to leave as much tire on the pavement as possible....
What do you see it doing the most here? Making smoke:
Besides the "drive for an hour, charge for an hour" isn't my claim, its theirs...argue with them.
