与内燃机不同的是，电力汽车具有完美的扭矩表现，其牵引力也因此得名，从零转速起，就像离弦之箭一样不需要借助加速箱。

Unlike internal-combustion engines, electric motors have full torque, as pulling-power is called, from zero revs. They are thus predisposed to go like a bat out of hell without the aid of a gearbox.

所以，即使一辆车可以产生更大的扭矩，同样需要足够的牵引力用以将这些扭转力矩传输到地面上。

So, even though a car may be able to produce more torque, there needs to be enough traction to transmit that torque to the ground.

而且牵引力好的那个车轮仅获得和差的车轮一样的很少量的扭矩，此时，你的车就不能正常运行。

And when the wheel with good traction is only getting the very small amount of toque that can be applied to the wheel with less traction, your car isn't going to move very much.
