Is the power of a car based on power or horsepower

Horsepower and horsepower are the same thing. These are different units, but they both indicate how much work the engine does per unit of time.

Meaning the number of times work is done per unit of power per unit of time.1kw is equal to 1.341 horsepower, which is an imperial unit. If you switch to metric units, then 1kw equals 1.36 horsepower.

Generally speaking, the maximum power of an engine only works at high speeds, so when you buy a car, both power and horsepower indicate how much work the engine does per unit of time. Maximum power determines the speed of the car, and maximum torque determines the speed of the car.

If the vehicle has more torque, the vehicle will go faster. The power of an engine is equal to the product of speed and torque. In the case of an engine of the same power, the lower the speed the higher the torque and the higher the speed the lower the torque.

The longer the cylinder stroke, the more torque and the lower the RPM for the same displacement. If the cylinder stroke is smaller, the higher the RPM, the lower the torque.

The other type of cylinder is the square cylinder, where the cylinder diameter and stroke are the same, so both torque and speed can be considered.

When choosing a car, consumers should not just focus on these superficial data, the most important thing is the feeling of driving it. Maximum horsepower is basically unplayable when driving on city roads, and more important than maximum horsepower is the car's dynamic responsiveness.
