What Does Engine Torque Mean?

[Selena]

Engine torque refers to the rotational force output from the crankshaft of an engine. Under a fixed power condition, it is inversely proportional to the engine speed—the higher the speed, the lower the torque, and vice versa. It reflects the vehicle's load capacity within a certain range. Like engine power, torque is one of the primary indicators of an engine, influencing vehicle performance, including acceleration, climbing ability, and suspension. Below is an introduction to engine torque levels: 1. For family cars, higher torque results in better acceleration; for off-road vehicles, higher torque enables steeper climbing; for trucks, higher torque allows for greater load capacity. Therefore, higher torque is generally preferable. 2. Greater torque improves the vehicle's responsiveness. Comparing vehicles with similar engine types, higher torque output means greater load capacity, better acceleration, stronger climbing ability, fewer gear shifts, and relatively reduced wear on the vehicle. Especially during zero-speed starts, vehicles with higher torque demonstrate superior speed-boosting capabilities. 3. For engines with the same displacement, higher torque indicates a better engine. When driving, this translates to a more responsive and enjoyable experience, with quick acceleration and a strong "back-pressing" sensation. Currently, one important metric for evaluating a vehicle is its 0-100 km/h acceleration time, which is directly determined by the engine's torque.
