What does the commonly mentioned torque in cars mean?

Torque, often referred to in cars, is the engine's torque, which refers to the rotational force output from the crankshaft. Under a fixed power condition, it has an inverse relationship with the engine's rotational speed—the faster the speed, the smaller the torque, and vice versa. Torque reflects a car's load-bearing capacity within a certain range. Like power, torque is one of the main indicators of a car's engine, influencing performance aspects such as acceleration, climbing ability, and suspension. For family cars, higher torque means better acceleration; for off-road vehicles, higher torque allows for steeper climbs; for trucks, higher torque enables carrying heavier loads. Generally, the higher the torque, the better the car performs, especially when comparing engines of the same displacement—higher torque indicates a superior engine.
I've been driving trucks for over a decade, and torque is exactly like that sudden burst of strength when you push a handcart. Think about it - the instant force an engine can deliver when it's working hard is torque. That moment when you step on the gas and get pressed back into the seat? That's torque in action. Last time I helped my brother pick a pickup, the salesperson kept emphasizing how the 3.0T diesel engine's 400 Nm torque could haul two tons up a slope without breaking a sweat. This spec deserves extra attention when buying vehicles - a work truck with weak torque is like an old ox climbing a hill, the engine roaring loudly while the vehicle crawls. Once met a young guy at the repair shop who forcibly increased torque by ECU remapping his naturally aspirated car, only to burn out the clutch plate in a week. This stuff really isn't about bigger being better.
