If I take it literally versus hyperbole and excitement, could there be uncertainty coming from the drive train design choices, system integration details?
Sure, but that sort of uncertainty should only increase the range of values you see out of the simulation. You could say “efficiency may range from 60% to 80%, so the output torque will range from X to Y”. If the real result is bigger than Y, something has gone wrong in your modeling or assumptions

Maybe they used a "all our previous tests showed 95% of efficiency compared to simulation, so let's multiply all our results, including top efficiency by this". Then their newest motor had 97% efficiency comparing to previous model.
