RotracE4-award winning rc car can haul 500 tonnes

[Toorbough ULL-Zeveigh]

very very slowly.
top speed isn't given but looks like walking speed on 4 motors x 37.5kW (80V, 930A).

also no clue or any pic of the type of battery, just 'few number of cells' whatever that means.
why are so many ev manufacturers so damn shy about revealing what brand of batteries they use?
all it takes is for one employee disgruntled or otherwise to spill the beans.

ROTRAC E4 is a compact, extremely mobile and powerful state-of-the-art road/rail shunter. It is purely driven and designed for trailing loads up to 500 t.
