轻车体使塔塔汽车使用了后置2缸引擎，（就像著名的平民汽车大众甲壳虫一样）从零到百公里加速仅用23秒，燃油使用率完美，一加仑能行驶大约56英里（24km/L），超过了丰田的prius混合动力车。

(100 km/h) in 23 seconds. Fuel economy is excellent: about 56 miles per gallon (24 km/L), better than a Prius, Toyota's hybrid sedan.

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.

It knows that this particle happened to have a height of 15, at the time of 0, and a velocity of 10, and it is falling under gravity with an acceleration of -10.

这个质点恰好处在高度为15的地方,零时刻,初速为10,并在重力作用下以-10的加速度下坠
