What do you mean by that question? There are a lot of things that change speed in a car. When more air and fuel enter the cylinders on a motor, it makes it speed up. When the motor speeds up, it makes the transmission spin faster, and when you shift gears it makes the driveshaft spin faster, along with the gears in the rearend, unless you have a front wheel drive car, then it makes the wheels spin faster. When the motor speeds up, the accessories driven by the belt or belts on the front of the motor spin faster. when the wheels spin faster, the car goes faster.
