How much can a snow-covered road affect fuel consumption?

A snow-covered road can significantly increase fuel consumption, primarily due to the additional resistance that vehicles must overcome while driving on such surfaces. Snow creates a slippery and uneven driving condition that requires more energy to maintain traction and stability. The increased rolling resistance, as well as the greater effort required for acceleration and the potential for wheel slip, contributes to a higher fuel consumption.

Research and practical experience indicate that the fuel efficiency of vehicles can drop by about 15-20% when driving on snow-covered roads. This figure considers various factors, including the vehicle’s weight, engine load, and driving habits, all of which are impacted by the challenging conditions presented by snow. Consequently, this choice accurately reflects the extent to which snow can hinder fuel efficiency on the road.
