What is the reason for the high engine speed of racing cars?

[ReeseRose]

Reasons for the high engine speed of racing cars: Racing cars need to squeeze more horsepower. Racing cars do not pursue torque performance at low speeds but aim for power output in the high-speed range. Power is the product of torque and speed, so the higher the speed, the greater the engine's power. The maximum speed of a household car engine is between 6,000 to 7,000 revolutions per minute (rpm), but many racing car engines can exceed 10,000 rpm. The maximum speed of an F1 racing car engine can even surpass 20,000 rpm. Such high speeds reduce the engine's service life, which is why most racing car engines have relatively short lifespans.
