These cargo boxes are the most premium of the lot. They have all the features of the Thule Motion, plus more for even smoother usability.
The felt lined interior gives your gear extra protection, and the white lid and LED light helps you see your packing in the dark.
The reinforced lid on the Thule Vector is the strongest and gives the box extra protection from impact (although all Thule cargo boxes are built to withstand lots of force).
These boxes can go up to XXL sizes, the largest Thule cargo box size. It has a handlebar which makes the box easier to open.
It also has the SlideLock system, a super handy feature which makes closing your box super simple. It means that the box automatically shuts when closed, so that you can close it with just one hand. The lock indicates when the box has been shut correctly with a red indication button.
Thule Force XT is a versatile cargo box you can rely on to carry all kinds of cargo.
It’s easy to mount on your roof racks and clicks when it’s properly mounted so that you know you’ve secured it correctly.
It can also be opened on either side (which you’ll be thankful for when you park on different sides of the street).
We know from data models and wind tunnel tests at the Thule Test Center that a rear-of-car cargo solution makes for better aerodynamics than having nothing on your vehicle at all.
It may seem strange at first – how can you possibly lower the air resistance by adding a large cargo box to the back of the car? But the results speak for themselves.
We drove a total of 5400 km in varying weather conditions with a fleet of Volkswagen ID4 – one of the most popular electric vehicles on the market. The results were interesting, to say the least.
The average consumption (kWh/100km) of a vehicle with the Thule Arcos towbar box was 95 %. This means that when we drove the Volkswagen ID4 with Thule Arcos mounted, the range improved by 5%* compared to the cars with nothing on them at all. So based on the battery of size of the ID4 and the consumption measured during the tests, we could travel roughly 17 km further*. This data is also backed up by computer simulations that showed a similar result.
We were able to drive farther – and at the same time, we could bring more gear.
This is supported by an external test by Vi Bilägare, Sweden's largest car magazine. It was founded in 1930 and features travel reports and test drives of cars and car accessories. They tested a roof box and our Thule Onto rear cargo box with both electric and fuel-driven cars.
Vi Bilägare found that the towbar cargo carrier created less wind drag than a roof box, and consumed less fuel and electricity than a car with nothing on it at all.
“One way to get more packing space without increasing energy consumption is the latest trend of mounting a cargo box on the car's towbar,” they explain in their article, “We found that both the petrol car and the electric car had slightly lower consumption with the box fitted than when the car was running completely empty on the test route”.

A rear cargo carrier lets you use your compact city car in a variety of ways. Load on your bikes and head out into the unknown one day, and pack your bags for a weekend trip the next. The choice is yours, we provide you with the solutions.
Roof boxes are designed to be as streamlined as possible and Thule designs some of the most aerodynamic boxes on the market. They are a great option for vehicles that can carry something on the roof.
Towbar cargo carriers, on the other hand, have the advantage of being at the back of the car in a place that barely affects wind resistance at all.
Towbar trailer cargo carriers like the Thule Arcos generate little to no wind drag. This means that, with a Thule Arcos towbar cargo carrier, you’ll be using the same amount of gas or electricity as a vehicle without anything on it.
They’re a great option for those who do not want to carry anything on their roof.
