If a car has less weight, it will speed up faster and stop faster because the momentum of the car is less than that of the heavier car. A: It is called the power to weight ratio.o. What an object weighs (which is the effect of gravity on the object's mass) does not affect it's speed whether it's free falling or on an incline. On Earth which has an at â¦ mosphere, drag has an effect on the speed of the object.
At a Glance: Spec'ing the correct drive-axle ratio can impact performance, speed, and fuel economy: 1  A higher ratio gives greater power, but lower top-end speed and fuel economy. 2  A lower ratio results in less pulling power, but improved top-end speed and fuel economy.
