I'm not sure this is true. I haven't looked into the Leaf's motor, but from what I remember from school, an electric motor's efficiency drops off at higher RPMs. Its torque/power curves are remarkably flat, maybe that's what you're thinking of?
Case in point: both the Model S and the Volt get improved efficiency at high speeds by using a different gear ratio (in both cases, through different motors with a different, but fixed, gear ratio).
