How does a roof rack affect fuel consumption?

Installing a roof rack on your car is a convenient solution for carrying additional cargo. However, many drivers do not think about how this can affect fuel consumption. Let's figure out why a roof rack increases fuel consumption and how to minimize this effect. You can also improve the practicality of your car and add versatility to it by using tuning accessories, a huge selection of which is available in our online store

Why does a roof rack increase fuel consumption?

1. Reduced aerodynamics : A trunk creates additional drag, especially at high speeds. This forces the engine to work harder to maintain speed.
2. Increased weight . The trunk itself and the cargo on it add weight to the car, which also increases fuel consumption.
3. Noise and vibration . At high speeds, the trunk can create turbulence, which puts additional strain on the engine.

How much does the consumption increase?

• At a speed of 100 km/h, a roof rack can increase fuel consumption by 10-20%.
• If the trunk is loaded, this figure can increase to 30%.
• In urban environments, the impact is less noticeable, but still present.

How to reduce the impact of the trunk on fuel consumption?

1. Remove the trunk when you don't need it . If you don't plan to carry cargo, it's better to dismantle the structure.
2. Use streamlined models, car boxes . Modern trunks have an aerodynamic shape, which reduces air resistance.
3. Distribute the load evenly . Do not overload the trunk and try to place the load closer to the center.
4. Watch your speed . At high speeds, air resistance increases, so try to drive moderately.

Conclusion

A roof rack is convenient, but it can significantly increase fuel consumption. To minimize costs, use it only when necessary and follow the installation and operating recommendations. This will help save fuel and reduce the load on the vehicle.
