Power, power train, weight, and aerodynamics are four interrelated aspects that affect how fast an automobile travels. Speed is correlated with horsepower in automobiles. Therefore, you need more horsepower if you want to go farther and accelerate more quickly. Contrarily, torque is the expression of a rotating or twisting force. Torque is produced in cars by the engines, which revolve around an axis. Another way to increase a car's speed is to use forced induction, which are turbochargers and superchargers together.
