Removing an unused roof rack or roof box from a vehicle decreases aerodynamic drag and helps reduce fuel consumption.
Cevap: Cevap
Cevap
True. Removing an unused roof rack or roof box reduces aerodynamic drag (wind resistance), which lowers engine workload and decreases fuel consumption.
Any item attached to the exterior of a vehicle increases air resistance (aerodynamic drag). Removing unused roof equipment allows air to flow smoothly over the bodywork, reducing engine workload and lowering fuel usage.
