Is Higher Torque or Higher Power Better for an Engine?

[MacElisa]

We know that a car's power equals torque multiplied by rotational speed, so the relationship between torque and power varies depending on the vehicle model. Automotive torque represents the magnitude of the engine's output moment. The greater the torque, the stronger the engine's rotational force. This is intuitively reflected in an SUV's strong climbing ability or a truck's capacity to carry heavy loads. For our family cars, the greater the torque, the easier it is for the vehicle to start or accelerate. But why do high-torque machines like tractors not provide a strong sense of acceleration? This leads us to the concept of power. At a constant power level, the higher the rotational speed, the weaker the torque becomes. This is why tractors cannot run very fast. On the other hand, vehicles with higher power perform better in terms of torque at high rotational speeds. High-performance cars and sports cars pay more attention to these metrics. For example, the Lamborghini Aventador ("Big Bull") has a higher maximum power than maximum torque, indicating its pursuit of higher speeds. Now, do you understand whether higher torque or higher power is better for an engine?

I think this is a pretty common issue. Having driven for many years and commuting daily in the city, I prefer cars with higher engine torque. With greater torque, the car accelerates quickly from a standstill – just step on the gas at a traffic light and you're off, without getting honked at by cars behind you. Climbing slopes is also effortless, especially on steep inclines where the car powers up without straining. Higher horsepower is useful on highways for faster speeds, but most city roads don't require such high velocity, and it might just lead to higher fuel consumption. A torque-rich car also handles loads more easily, like when taking the family out on weekends with some luggage – no stress at all. So if your daily driving is mostly in congested urban areas, I'd recommend prioritizing torque. It makes driving more comfortable and practical, significantly improving your mood.

As a young car enthusiast who loves speed, I particularly value high-power engines. With greater power, the car can race incredibly fast on the highway, effortlessly overtaking with just a press of the accelerator—it's thrilling. While torque is good for quicker starts, power is the key to sustained acceleration, allowing you to maintain high speeds on the track or open highways. High-power engines perform best at high RPMs, delivering a sense of control and an exhilarating, endless surge of power. Of course, they do consume more fuel, making them ideal for those who crave speed. Torque has its merits, but if you want that lightning-fast, wind-in-your-hair experience, high power is the real king—ensuring every drive is packed with excitement.

In my experience driving trucks for cargo transport, torque is definitely more important than horsepower. With higher torque, the vehicle starts up quickly, handles heavy loads uphill with ease, and avoids getting stuck or consuming excessive fuel like vehicles with low torque. Higher horsepower is beneficial for high-speed driving, but in practical scenarios like urban deliveries or rural dirt roads, good torque makes driving effortless and worry-free. My old pickup truck was designed with high torque, making loading and unloading cargo a breeze while also saving on fuel costs. Excessive horsepower is unnecessary, as it increases costs and can lead to waste. So, if you're driving for work, prioritize an engine with strong torque to ensure reliability.
