Longer answer: For a given flux density, torque is proportional to the rotor volume. To get higher efficiency usually requires adding material (copper) to the windings to lower electrical resistance, which may require a larger diameter motor.
Having said that, for a given motor design you are likely to get better range by accelerating at lower torque for a longer time as opposed to more exciting driving.
I never understood peoples enthusiasm for torque numbers. It all goes through gears and then gets divided by tire radius to get a forward force, and then gets divided by vehicle weight to get acceleration. Just give us the final acceleration in G's please. Similarly, power is important but power/weight is going to be more indicative of 0-60 time.
