The amount of energy required to accelerate to a given speed is the same regardless of how quickly you get there. There's practically no difference in efficiency (especially in an EV) getting up to 60 MPH in 3s vs 10s.
There's a reason why EVs are tilted towards being quick; and that's because the only downside is a marginal increase in cost, size, and weight for a more powerful motor. It hardly affects range at all.
In fact, Tesla's first performance version of the Model S was more efficient than the slower single motor version because it utilized a highly efficient "cruise" motor, and only used the inefficient "acceleration" motor when the extra power was needed.
