What does maximum torque of 145 mean?
2 Answers
Maximum torque of 145 means the vehicle's engine has a maximum torque of only 145 N·m. Concept of torque: Torque refers to the average moment force output from the crankshaft when the engine is running, commonly known as the engine's "rotational force". It is an important parameter of engine performance. The greater the torque, the more "force" the engine outputs, the faster the crankshaft speed changes, and the better the vehicle's climbing ability, starting speed, and acceleration. Maximum torque: The engine's maximum torque is related to the design of the engine's intake system, fuel supply system, and ignition system. At a certain speed, when these systems' performance matches optimally, the maximum torque can be achieved. Additionally, the engine's power, torque, and speed are interrelated, with the specific relationship being: Power = K × Torque × Speed, where K is a conversion factor. When selecting an engine, it's also necessary to consider how to use it reasonably without wasting existing capabilities.
In the car specifications, I see a maximum torque of 145, which I understand refers to the engine's maximum rotational force output reaching 145 Newton meters, with the unit being Newton meters, abbreviated as Nm. Simply put, torque is like the force of an arm turning a screw—the higher the value, the more powerful the car is during starting and acceleration, especially playing a key role in the low RPM range. Typically, when the engine speed reaches a certain peak, such as between 2500 to 4000 RPM, the torque can reach this maximum value. I think this is particularly important for daily driving because a car with high torque starts faster at traffic lights, climbs steep slopes more easily, and can better tow heavy loads like suitcases or small trailers. Compared to horsepower, which focuses on high-speed performance, torque emphasizes practicality and responsiveness. If you often drive on city roads or suburban mountain roads, choosing a car with a torque value around 140 to 180 Nm would be more reliable, while also ensuring the units are consistent to avoid confusion.
