What safety feature does a torque converter provide to an automobile?

A torque converter is a crucial component of an automobile's automatic transmission system, and it serves multiple purposes, one of which is to prevent engine stalling. This is achieved by allowing the engine to remain running even when the vehicle is stationary and in gear. When the vehicle is at a standstill, the torque converter allows a certain amount of slippage between the engine and the transmission, which helps maintain engine speed without stalling.

As the driver presses the accelerator, the torque converter effectively multiplies the engine's torque, providing the necessary power to move the vehicle forward without requiring the driver to engage the clutch, as would be necessary in a manual transmission. This smooth transfer of power enables the driver to focus on steering and control rather than worrying about stalling the engine.

While the other options may relate to various components or capabilities of a vehicle, they do not pertain directly to the primary function of a torque converter. Enhanced braking systems and improved steering response involve different systems altogether. Additionally, reduction of weight is not a feature provided by the torque converter, but rather pertains to the overall construction of the vehicle. Therefore, the prevention of engine stalling stands out as the key safety feature provided by a torque converter in an automobile.
