I'd like to add that the 200 ft-lbs of torque you see on the electric motors isn't the same as on your gas engine. Their torque curve looks something like this:
As you rev your gas engine up, it builds more power. That's not true of electric motors. Power is constant, so torque is actually highest at 0rpm. In an electric car, if you mash the accelerator, acceleration is constant because torque drops as RPM rises.
This is why they make a great compliment to gas engines - the produce the most power where gas engines produce the lease.
But you still have to get the energy to run them from somewhere.
