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.

为了对这种新型的转向管柱的性能进行评估，其中一点是需要测量它的万向节的微小摆动扭矩。

One of performance evaluations to this new type of steering tube is to measure its gimbal's micro-torque.
