what is torque in cars

Torque is a physical quantity that indicates the traction in an engine design. It is the twisting force that the crankshaft provides in a car. Torque is used to measure the work an engine can perform. It is a force that acts on a body through a lever arm. In simpler terms, torque represents how strong an engine is. It is the rotational force that translates into acceleration and ultimately, speed. Torque is expressed in pound-feet (lb-ft) or newton-meters (Nm) . The interaction of torque and engine speed (rpm) determines the engines power output. Torque is calculated by multiplying the force you are exerting on the wrench by the length of the wrench. In a car, the engine is where torque is generated. Torque is important because it determines how quickly a car can accelerate and how much weight it can tow.
