Depends on model... Atto3 is tuned for fast acceleration between 0-50, usually after 50, my ICE easily catches up to it and overtakes it.
For certain other models, 100 onwards also easy to accelerate, but hor, your consumption prepare to go up. I tried before for testing purposes. 70, 80, 90 up to 150, honestly the usage of power doesn't differ much despite sayings claim that 80 is most conservative and saves the power consumption best.
EVs have no engine, no gears, so the torque is instant, which also results in higher wear and tear on the tyres.... trade off.
