How will a Roof Rack Affect Your Car?
Adding a roof rack to your car can greatly increase its utility. It creates extra space for luggage, sporting equipment, or even bulky items that wouldn’t fit in the boot. However, you might be wondering, how will a roof rack affect your car? Specifically, its performance, fuel efficiency and even safety.
In this guide, we’ll pull back the curtain on this topic, providing you with comprehensive insights into the effects a roof rack can have on your car. At the end of this guide, we’ll also share how a load should be carried on your roof rack and tell you whether or not a car roof rack is a worthwhile addition.
So stay with us and let’s dive in!
How will a Roof Rack Affect Your Car?
Undeniably, a car roof rack offers the appeal of added convenience and additional storage for those who require it. However, our primary focus here is to enlighten you on the consequential impact it may have on your vehicle.
So, let’s take a closer look at some of the possible effects a roof rack can have on your car.
How a Roof Rack Affects Handling and Stability
The addition of a roof rack to your vehicle can result in noticeable changes to its handling and stability. This alteration is primarily driven by the shift in the centre of gravity upwards. It makes your car feel different when you’re manoeuvring it. This is particularly true at high speeds or when navigating corners.
Consequently, you might find that your vehicle leans more than you’re used to. Even the reliable Suzuki Vitara, known for its agile and pleasant driving, can take some getting accustomed to when a roof rack is attached to it.
Moreover, heavy loads on the roof rack can exacerbate this effect. The heavier the load, the higher the centre of gravity moves. This can potentially make the car unstable, especially when driving at higher speeds or in windy conditions.
How Car Roof Rack Impacts the Fuel Economy
It’s a fairly understandable concept when we look at the laws of aerodynamics. In their light, you’re looking for a sleek, streamlined, and comfortable car to cut through the air with minimal resistance.
When you add a roof rack, and especially if you load it up, you’re essentially presenting a larger obstacle to the wind. This increased wind resistance, often referred to as drag, means your car has to work harder, and therefore use more fuel, to maintain the same speed.
The impact on fuel consumption can be quite noticeable, especially at motorway speeds. A roof rack, even when it’s empty, can decrease fuel efficiency.
When fully loaded, the impact on fuel economy can be more significant.
We aren’t providing you with exact figures on the impact. This is because the actual effect on your fuel consumption will depend on various factors. These are the shape and size of the car roof rack. The weight and aerodynamics of the load. The speed at which you’re travelling. And even the wind conditions.
But we’ll say this: If you’re using a roof rack for long trips or have heavy loads, it will impact the fuel economy of your car.
For those curious about the statistics, you can get a rough estimation, although we must reiterate that it varies based on the aforementioned factors.

How a Roof Rack Affects Your Car’s Performance
Adding a roof rack and subsequently loading it up will add weight to your vehicle. This additional weight can have a visible effect on how your vehicle performs in certain scenarios.
Acceleration might be the first area in which you notice a difference. Simply put, the more weight a vehicle carries, the more power it needs to get moving.
Consequently, you might find your car somewhat less sprightly when pulling away from a stop with a loaded roof rack, as it has to work harder to overcome the extra weight. Basically, you’ll have to push the pedal harder than before.
Braking performance can also be affected. Greater mass means greater inertia, so your vehicle will require more distance to come to a complete stop when it’s carrying a load on the roof. Thus, it’s highly recommended to adjust your driving style, allowing for longer stopping distances and a more considered approach to speed.
Lastly, the overall strain on your vehicle’s engine and transmission is something to consider, particularly on long journeys or when travelling up steep inclines. The added weight of the roof rack and its load can put more stress on these components, potentially shortening their lifespan.
How A Roof Rack Can Potentially Depreciate Your Car’s Value
While a roof rack is undoubtedly a practical addition for the right person, it’s worthwhile to consider how it might contribute to the depreciation of your vehicle’s value.
Here’s why a roof rack could potentially depreciate your car’s value
- A roof rack is a visual modification/alteration. Some people might not like the look.
- The added weight can negatively impact fuel consumption and performance. This might affect your car’s desirability to potential buyers.
- If you regularly use it for heavy loads, then scratches or wear on the roof from loading/unloading could decrease its aesthetic appeal.
- Not every car buyer needs or wants a roof rack, so fitting one could limit the potential interested parties in the future.
- If not properly installed or removed, it can cause cosmetic damage to your vehicle’s paintwork.
- Some buyers will see a roof rack as an indication that the vehicle has been used for heavy-duty work, which might turn them away.
- Loading large or heavy items onto the roof rack can sometimes cause dents or damage to your car’s roof, further decreasing its value.
- In rare cases, some car insurance companies might charge higher premiums if you have a roof rack installed on your vehicle.
It might fulfil your needs, but a roof rack affects your car’s value in many ways. If you’re still going to use it, let us share
How Should a Load Be Carried on Your Roof Rack
If you’re asking yourself how a load should be carried on your roof rack.
Here are some safety considerations to keep in mind when carrying a load on a roof rack:
- Ensure that the roof rack with the load doesn’t exceed your car’s weight limit.
- Check legal requirements and regulations in your area to ensure that roof racks are permitted.
- Load the roof rack carefully and evenly, avoiding any sudden weight shifts.
- Always fasten the load securely to prevent items from falling off while driving.
- Regularly check and maintain your roof rack to ensure it’s securely attached to your vehicle.
- Adjust your driving style, especially in high-speed or windy conditions, when using a loaded roof rack.
- Avoid sharp turns and manoeuvres when carrying a load on your roof rack.
- Handle items carefully when loading and unloading them from your roof rack to prevent damage to your vehicle.
- Be aware of the added wind resistance and potential impact on driving stability when using a roof rack with load.
- Get it installed by a professional or follow the manufacturer’s instructions carefully if you’re installing the roof rack yourself.
- Consider the potential effects of a loaded roof rack on your vehicle’s braking performance, acceleration, and engine/transmission strain.
By taking these safety considerations into account, you can safely carry a load on your roof rack and ensure you and others on the road are not in harm’s way.
