It means torque turning force. Besides the power of the motors, the torque is also specified, for example 145 Nm at 3800 minutes / revolution. WHAT DOES IT DO? Simply put, it is more comfortable to use if the torque of a car, or rather its engine, is good because the engine can be used without changing gear over a wider rpm range. Or, in emergencies, less need to change gear is felt. Besides the number specified as the highest torque, the speed at which this figure is obtained is also important. Since the motors are mostly used at low and medium speeds, it is very useful to have high torque starting from low speeds, especially in the city. Thus, it is possible to continue the movement without going into lower gear. In general, the torque increases as the engine volume increases, but the torques and "torque curves" of motors with the same engine volume may differ. The reason for this is the differences in engine design. The diameter and stroke of the cylinders, firing timing and some other features are the features that we can call "technology" in general. Also, as everyone knows, diesels have a "torque" engine. This means that it provides high torque at low rpm. Unlike gasoline engines, the highest torque of diesel engines is achieved at 1800-2500 minutes / revolution. In this way, the engine "pulls" without the need for many revolutions. Let's say a diesel engine has the same highest torque as a diesel, yet the diesel engine is more advantageous because it provides this torque at a lower speed. The practical advantage of this is, for example, when climbing uphill, you can accelerate in a diesel engine car when the engine is at 2000 rpm in third gear, and the car can accelerate, the car with a gasoline engine cannot accelerate and most likely will have to shift into a lower gear. Diesel engines are used especially in commercial vehicles since they provide high traction at low revs. Engine horsepower and torque should not be confused. These are different things. To understand the meaning of torque in concrete terms, an example can be given as follows. Let's say there are two cars with the same horsepower. Their torque is different. When you dock and fasten both cars with their backs towards each other, when the two cars move (like a rope-pulling game), although the horsepower is the same, the high torque draws the other one.
