Why do F1 car have high horsepower rather than torque?

Click For Summary
SUMMARY

F1 cars prioritize high horsepower over torque due to the fundamental relationship between power, torque, and rotational velocity. Power, defined as the rate of doing work, is calculated using the formula Power = Torque * Rotational Velocity. This means that while torque can be exchanged for speed through gearing, the overall power output remains constant. The discussion emphasizes that a cyclist, despite potentially generating high torque, cannot exceed their inherent power output, illustrating why high horsepower is crucial for performance in racing contexts.

PREREQUISITES
  • Understanding of basic physics concepts, particularly power and torque

I've heard the analogy that a high torque car is like a bodybuilder, it is powerful but slow.
And a high horsepower car is like a sprint runner, it runs fast, but not as powerful.

Considering other factors constant.
if each tries to ride a bicycle to a certain speed,
and the runner is given a low gear ratio, while the bodybuilder is given a high gear ratio.
Wouldn't they both perform similarly?

Power is what matters. Power is the rate of doing work. The rider with the most power will win.

Power = Torque*rotational velocity
In SI units
Watts = Newton metres * radians/second (=joules/second)

Gears, or any other mechanical advantage, can exchange torque for rotational speed or vice versa but power remains constant.
A cyclist with adequate gearing could produce more torque than a Veyron, but the cyclist still only produces the same pitiful power output he always did.
