Maybe they were using a 50v rated brushed shunt wound motor. Pulse width would be incredibly short.
If you go up into the k volt range, motor currents are going to drop for a given hp, but the C of Drag has to be incredibly low and it needs to be very lightweight.
Sounds like unicorn corral material.

Mercedes-Benz observed something like 720-miles, on around 100-kWh pack for their EQXX concept, so, around 7.2-miles / kWh.
They averaged about 57-mph over the length of the trip. Some range would be attributed to regen. coming over the Alps.
Lightyear Zero has a little lower drag coefficient. I'm unsure about it's frontal area.
Cd 0.175 isn't the 'floor' for drag. Wolf Hucho spoke of Cd 0.09 as the technologically-feasible limit, as of 1987. And that would all depend on what priority was assigned to aerodynamics, with respect to the vehicle specification.
It would mean the end of the 'Paris Dressmakers,' and I have no illusions about the automotive industry ever giving in to physics.
