As soon as June arrives, we start packing for the seaside or the mountains, and our cars end up filled to the roof. Sometimes even beyond it. Every summer, I see roof boxes wobbling on the motorway, bicycles strapped down with belts and cars swaying whenever a strong gust of wind hits. A roof rack is incredibly handy, but only if you know how to use it properly. So I want to talk you through a few things you should never compromise on. It's about keeping you safe, my friend. And the first thing you need to understand is the Audi roof rack weight limit.
Audi Roof Rack Weight Limit: How Much Can Your Car Carry?
Every car has a maximum permitted roof load, and you'll find the exact figure in the owner's manual. For most Audi and VW models, we're talking about 75 to 100 kg. But here's something a lot of people overlook. That limit includes absolutely everything – the roof bars, the roof box and all the luggage inside. If your roof box weighs 15 kg and the bars weigh another 5 kg, you've already used up part of your allowance before you've even packed your first bag.
Never exceed your car's maximum permitted roof load. It simply wasn't designed to carry more than that. The roof, the bars and their mounting points take the greatest strain at exactly the worst possible moment – during sudden braking or a sharp turn. Trust me, it's not worth the risk.
How Does Your Car Handle with Luggage on the Roof?
When you put luggage on the roof, you raise your car's centre of gravity. In simple terms, that means it leans more in corners, gets pushed around more by crosswinds and needs more distance to stop. You'll also notice higher fuel consumption and more wind noise. That's why I want you to take things a little easier when you're carrying a load on the roof. The manufacturer usually recommends keeping your speed below 130 km/h with roof luggage fitted. Just remember that your car won't handle quite the way it normally does.
How Should You Pack and Secure Your Roof Box?
- Keep the heavy stuff low down, in the car's boot. Put lighter, bulkier things on the roof – jackets, sleeping bags and shoes.
- Spread the weight evenly. Don't cram everything into one end of the roof box, however convenient it might seem.
- Tighten the roof bars to the correct torque and check them again after the first 50 km. The mounting points can settle slightly after installation.
- Make sure the roof box is locked and the lid is completely closed. Just because it looks shut doesn't mean it actually is.
- Forget about automatic car washes when you've got a roof box fitted. And keep an eye on your car's overall height when entering an underground car park.
Genuine or Universal Roof Bars: Which Should You Choose?
Universal roof bars attach to the door frames using clamps. Genuine roof bars, on the other hand, are designed specifically for the mounting points on your particular model. They've been crash-tested, won't scratch your paintwork and won't whistle away on the motorway. At Das Auto Service, we only fit genuine roof racks. And I'll tell you why. In a collision at 50 km/h, a roof box carrying 50 kg of luggage can shoot forwards like a missile. That's why I wouldn't experiment with the mounting system. And I wouldn't recommend you do it either.
What Should You Do with Your Roof Rack After the Trip?
When you're not using the roof bars, just take them off. Your car will use less fuel, the cabin will be quieter, and the bars won't spend the entire year baking in the sun and getting soaked by the rain. Give them a clean and put them away together with their keys. That way, next summer you won't have to turn the whole house upside down trying to find them.
A tip from Kris Mladenov: Before you set off, open your owner's manual and check exactly how much weight your car's roof can carry. Add up the weight of the roof bars, the box and all your luggage. If you're getting very close to the limit, leave something at home. Trust me, the seaside will still be there even if you don't bring that third pair of shoes.
I want you to get to the seaside safely, without unnecessary stress or nasty surprises. If you've found this helpful, share the article with the friends you travel with. Especially that one friend who tries to pack half the house onto the car every summer.

Frequently Asked Questions
Audi Roof Rack Weight Limit: How Much Can Your Car Carry?
Most Audi and VW models can carry between 75 and 100 kg on the roof. But that includes the roof bars, the roof box and all the luggage. You'll find the exact weight limit for your car in the owner's manual.
How fast can I drive with a roof box?
The manufacturer usually recommends staying below 130 km/h. If it's particularly windy or your car is fully loaded, slow down even more. There's no need to rush.
Does the weight of the roof box count towards the roof load limit?
Yes, and this really matters! You need to count everything – the roof bars, the box itself and all the luggage inside. Don't just look at how much the stuff you've crammed into the box weighs.
