How many horses does my car have? Discover how to calculate the power of your vehicle

If you are one of those who wonders how many horses your car has, you are in the right place. In this article, we will explain how to calculate the engine power of your vehicle and how to obtain this information through the data sheet or other methods. Read on to find out!

What is the power of a car engine?

Before we dive into how to calculate horsepower for your car, it's important to understand what exactly engine horsepower is. Power refers to the ability of an engine to do work in a given period of time. In the case of cars, it is measured in horsepower (CV) or kilowatts (kW).

Engine power is a key factor when evaluating a vehicle's performance. The higher the power, the faster you can accelerate and reach high speeds. However, other factors such as the weight of the car, aerodynamics and engine efficiency must also be taken into account.

How to calculate the power of your car?

There are different methods to calculate the engine power of your car. Below, we explain the most common:

1. Technical sheet of the vehicle

The easiest and most accurate way to know the power of your car is through the technical data sheet. In this document, which is usually in the owner's manual or registration certificate, you will find all the relevant information about your vehicle, including engine power.

Look for the section corresponding to power and you will see that it is indicated in horsepower (CV) or kilowatts (kW). If you have questions about how to interpret this information, you can consult your owner's manual or search online.

2. Calculation from the displacement

Another method to calculate the power of your car is from the displacement of the engine. Displacement refers to the total volume of the engine's cylinders and is measured in cubic centimeters (cc).

To do this calculation, you will need to know the specific formula for your engine type. For example, in gasoline engines, the general formula is:

Power (CV) = (Displacement (cc) x Number of cylinders) / 100

If you have a 4-cylinder engine with a displacement of 2000 cc, the calculation would be:

Power (HP) = (2000 cc x 4) / 100 = 80 HP

Remember that this method is an estimate and there may be variations depending on other factors such as the efficiency of the motor and the technology used.

Frequently Asked Questions (FAQs)

1. Can I increase the power of my car?

Yes, it is possible to increase the power of your car through modifications to the engine or exhaust system. However, it is important to note that these modifications may affect the manufacturer's warranty and may not be legal in some countries. In addition, it is advisable to have the advice of a professional to ensure that the modifications are carried out safely and effectively.

2. Does engine power affect fuel consumption?

Yes, engine power can affect fuel consumption. In general, the higher the horsepower, the higher the fuel consumption. However, this also depends on other factors such as the car's weight, aerodynamics and driving style. It is important to find a balance between power and efficiency to optimize fuel consumption.


In summary, calculating the power of your car's engine is essential to know its performance and acceleration capacity. You can obtain this information through the vehicle's technical data sheet or through calculations based on displacement. Remember that power is not everything, and other factors such as weight and engine efficiency also influence the performance of the car. If you have questions or need advice, do not hesitate to consult a professional in the sector.
