What is the primary function of the torque in a vehicle?

• A. To measure fuel efficiency
• B. To produce rotation of the wheels
• C. To maintain engine temperature
• D. To control the car's suspension system

Answer: (B)

The primary function of torque in a vehicle is to produce rotation of the wheels. Torque is a measure of the twisting force that causes an object to rotate around an axis. In the context of vehicles, torque is generated by the engine and transmitted through the drivetrain to the wheels. This rotational force is crucial for propelling the vehicle forward or backward. When the engine produces torque, it allows the wheels to turn and move the vehicle. The amount of torque available at various engine speeds determines a vehicle’s ability to accelerate, climb hills, and carry loads. In essence, higher torque values contribute to better performance during starting and low-speed driving, which is why torque is a critical aspect of vehicle dynamics and is often discussed in terms of engine specifications. In contrast, other functions mentioned in the choices, such as measuring fuel efficiency, maintaining engine temperature, and controlling the car's suspension system, do not directly relate to torque's primary role in generating movement.
