Do Roof Racks Use More Fuel?

With rising fuel costs and growing awareness around fuel efficiency, you may have seen advice suggesting you should remove your roof rack to reduce fuel consumption.

And in many cases, that advice is correct.

But like most things, it’s not that simple.

Why Roof Racks Can Increase Fuel Consumption

Roof racks can impact fuel economy because they change the way air flows over your vehicle.

At higher speeds, wind resistance (also known as aerodynamic drag) increases. Bulky or poorly designed roof racks can disrupt airflow, forcing your engine to work harder and use more fuel.

This is why general advice often recommends removing your roof rack when it’s not in use.

The Real Issue Isn’t Roof Racks — It’s Drag

Not all roof racks are created equal.

Older or generic designs tend to sit higher on the vehicle and have larger frontal profiles, which increases drag significantly.

That’s where the difference lies.

How Aerodynamic Roof Racks Reduce Fuel Impact

A well-designed roof rack works with your vehicle’s airflow, not against it.

Wedgetail roof racks are engineered with:

• A low-profile design that sits closer to the roofline
• Streamlined edges to reduce wind resistance
• A structure that maintains airflow across the vehicle

The result is a system that minimises drag and reduces the impact on fuel consumption compared to traditional rack designs.

Do You Need to Remove Your Roof Rack?

If you’re running a bulky or outdated roof rack, removing it when not in use can help improve fuel efficiency.

But if your setup is built with aerodynamics in mind, the difference is far less significant.

For many drivers—especially those using their racks regularly for work or travel—removing and reinstalling a roof rack simply isn’t practical.

Choosing the Right Roof Rack for Fuel Efficiency

If fuel economy matters to you, the solution isn’t necessarily removing your roof rack.

It’s choosing the right one.

Look for:

• Low-profile mounting
• Aerodynamic design
• High-quality engineering
• Systems designed specifically for your vehicle

A poorly designed rack will create drag.
A well-designed one will minimise it.

And that’s a difference worth considering.
