I don't understand why quick acceleration uses more energy. As a physicist I know that it takes the same amount of energy to accelerate something quickly as it does slowly. If the final velocity is the same, the total change in kinetic energy will be the same. So why does it take more energy to accelerate the Volt faster?
I can see with an ICE, where flooring the pedal injects extra fuel into the cylinder. Is the electric motor also less efficient for some reason when it puts out more torque? That's the only explanation I can think of, but perhaps I'm missing something.
