They might also be running a higher voltage battery.
Only so many ways you can do 32kwh. 40 ah @ 800V. That's only about double what is in the ranger right now which would give me 80 miles range.

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.
