how will a roof rack affect your car

A roof rack affects a car by increasing aerodynamic drag, which leads to reduced fuel efficiency (typically by 5-15% when empty, and more when loaded), adding extra weight, and raising the vehicle's center of gravity. This results in altered driving dynamics, including decreased handling precision and stability, longer braking distances, and reduced maneuverability. Roof racks also increase wind noise and can make the vehicle taller, which may affect clearance in tunnels or parking. Despite these drawbacks, a roof rack provides valuable extra storage space for bulky items, enhancing the vehicle's utility for travel and outdoor activities. Removing the roof rack when not in use helps minimize negative impacts on fuel consumption and driving comfort.
