What style of differential does not vary the amount of torque sent to the wheel?

The choice of an open differential is correct because it allows for the wheels on an axle to rotate at different speeds during turns, but it does not adjust or vary the amount of torque sent to the wheels. This means that both wheels receive an equal amount of torque regardless of their speed. As a result, when one wheel encounters less traction (like on a slippery surface), it may spin freely while the other wheel receives no additional torque to help propel the vehicle forward.

In contrast, a limited-slip differential does manage torque distribution between the wheels, providing more torque to the wheel with better traction in order to improve stability and control. A locking differential can effectively "lock" both wheels together, allowing them to spin at the same speed, which can be beneficial in off-road situations but does vary the torque when engaged. Torque vectoring differentials actively distribute torque between the wheels based on driving conditions to enhance performance and cornering ability, further emphasizing the contrast with an open differential's simplicity of equal torque distribution.
