Torque, RPM, Power

Car torque, RPM (revolutions per minute), and power are important terms related to the performance and characteristics of a car's engine. Here's a brief explanation of each:


Torque is a measure of the rotational force produced by the engine. It is typically expressed in units of pound-feet (lb-ft) or Newton-meters (Nm). In simple terms, torque is the force that propels a car forward. It determines the car's acceleration and ability to overcome resistance, such as gravity and friction. Higher torque allows a car to accelerate more quickly, especially at lower speeds. Torque is generally listed alongside the engine's RPM range, indicating how the torque output varies at different engine speeds.

RPM (Revolutions Per Minute)

RPM refers to the number of times the engine's crankshaft completes a full rotation in one minute. It is a measure of the engine speed or revolutions per minute. The RPM range indicates the engine's operating range, from idle (lowest RPM) to the redline (highest RPM). The redline is the maximum safe RPM limit beyond which the engine should not be revved. Each gear in a car's transmission has a specific RPM range within which it performs optimally.


Power is the rate at which work is done or energy is transferred. In the context of cars, power typically refers to engine power or horsepower (hp) and kilowatts (kW). It represents the engine's ability to deliver work over time. Power is related to both torque and RPM, and it can be calculated using the following formula: Power (in horsepower) = (Torque × RPM) / 5,252. This formula shows that power is directly proportional to torque and engine speed. Higher power output usually translates to faster acceleration and higher top speed.

It's important to note that torque and power alone do not provide a complete picture of a car's performance. Factors such as weight, aerodynamics, transmission, and gearing also play significant roles. Additionally, torque and power curves are often graphed to show how they vary across the engine's RPM range, giving a better understanding of the engine's performance characteristics.

The torque curve and power curve are graphical representations that illustrate how torque and power output vary across the engine's RPM range. They provide valuable information about the engine's performance characteristics. Here's what you need to know about each curve:

Torque Curve

The torque curve represents the engine's torque output at different RPMs. It is a graph that plots torque (usually in pound-feet or Newton-meters) on the vertical axis against RPM (revolutions per minute) on the horizontal axis. The shape of the torque curve shows how torque builds and declines as RPM increases or decreases. The torque curve is important because it indicates the engine's strength or pulling power at different RPMs. Engines with a flat or broad torque curve provide ample torque across a wide RPM range, resulting in strong acceleration and responsiveness. On the other hand, engines with a peaky torque curve deliver their maximum torque output at higher RPMs, requiring more revs to achieve optimal performance.

Power Curve

The power curve represents the engine's power output at different RPMs. It is a graph that plots power (usually in horsepower or kilowatts) on the vertical axis against RPM on the horizontal axis. The power curve is derived from the torque curve using the formula: Power (in horsepower) = (Torque × RPM) / 5,252. Similar to the torque curve, the power curve shows how power builds and declines across the RPM range. Engines with a broad and flat power curve deliver consistent power across a wide RPM range, providing strong acceleration throughout. Engines with a peaky power curve deliver their maximum power output at higher RPMs, making them more suitable for high-speed performance and racing.

Analyzing the torque and power curves together provides insights into how the engine performs in different driving scenarios. For example, a torque curve with high low-end torque is beneficial for quick acceleration from a standstill, while a power curve with high top-end power is advantageous for achieving high speeds. Automakers often optimize the engine design, intake, exhaust, and other components to shape the torque and power curves according to the desired performance characteristics of the vehicle.

It's worth noting that torque and power curves can vary significantly depending on the engine design, aspiration (naturally aspirated or turbocharged), and other factors. They are typically provided by manufacturers to help consumers understand the engine's performance and characteristics before making a purchase.
