When driving on difficult terrain like snow, how does the torque requirement change?

In difficult terrain such as snow, more torque is needed to effectively propel the vehicle. Torque refers to the rotational force that the engine produces, and it is essential for overcoming resistance encountered in challenging conditions. Snow can create substantial traction loss between the tires and the surface, requiring the engine to exert additional force to maintain momentum and control.

When driving on snow, not only is there a need to initiate movement from a standstill (which requires a higher torque), but the vehicle must also be able to maneuver and maintain speed despite the slippery conditions. Thus, increased torque allows the vehicle to dig in, providing better traction and helping prevent the wheels from spinning, which can happen if torque is insufficient.

The other choices do not accurately reflect the reality of driving in such terrains, as less torque would hinder the vehicle's ability to move effectively, torque requirements varying under normal conditions without considering the added difficulty of snow, or suggesting that torque is not a factor, which disregards its critical role in vehicle performance under adverse conditions.
