Thule Motion XT-L

It is the smallest option in the Thule Motion XT series, and it offers 16 cubic feet of inner space for holding items for up to 3 people. If you are a camping lover, you have to ensure that the chosen cargo box can load enough gear and items for your family’s outdoor adventures. It can carry up to 165 lbs of stuff, and it weighs 42 pounds. According to the manufacturer’s statistics, its dimensions are 77″ long, 36″ wide, and 17″ tall, so you may use these numbers to figure out if you can use it on the roof of your vehicle or not. It works with most factory rack systems and other roof racks: aero crossbars, elliptical bars, round bars, and square bars. Even if it has broad compatibility with roof racks, we recommend you contact your local auto dealer to get one. By the way, cargo boxes must work with a crossbar because they can not independently stand on a car roof without any support. 

When you want to go for a sporting event like skiinggolfingfishing, or other gear-needed sports, you may need storage space on your car for transporting gear between locations. At a time like this, a cargo carrier can help a lot. According to the measurement of the Thule Motion XT 16 cubic feet cargo box, it can hold 5 to 7 pairs of skis3 to 5 snowboards, and you can put any gear that is no longer than 175 cm into the box with ease. 

It can open from both sides, so it is pretty easy to use when you pack it at home, beside a road, in the woods, or in other environments. It doesn’t have internal LED lights for dark time, but you can get one online. When the lid is open, two inner lifters hold the cover for you until you manually shut it down. 

The SideLock system automatically locks the lid when it is fully closed, so you have no chance to leave a half-open box behind before you start the car engine. Safe is always the priority for everything, so we recommend you read an article-is it safe to use a cargo box.

It is a combination of ABS plastic materials, and it is waterproof, durable, and sturdy. Its aerodynamic design reduces the wind drag and minimizes the effect on gas mileage, and its glossy black and gel-coat finish is resistant to chips, scratches, and UV rays

The Thule Motion XT series’ three options have some features in common, and the differences between options are the measurement and loading capacities. We won’t repeat the same info over and over again in this article, so you better know about that.

What do other people say about the Thule Motion XT series?

From Liam(Interview):

I had the Thule Motion XT XXL option for a while, and I cannot hold my passion for writing something down about the box. It is a great travel companion, and my kids love it. I drove 8k miles on a road journey with my kids and our luggage and kids’ soccer gear. We went through days of extreme weather conditions like a rainstorm, and our items were dry and safe all the time. I love this product, and it brings many conveniences to our life. 

From Oliver(Interview):

I have successfully installed it on my Honda Odyssey. It came to my home as expected, and there was slight damage on the corner because of the long way delivery through Phoenix, Arizona, and other territories. I drove at 85mph with it on the highways without a problem, but it affected the gas mileage by about 4%. When I install it, those clamps functioned smoothly. I did the installation alone, so I think everyone can do the assembly alone without a tool in minutes.

From Henry(Interview):

We had a black cargo carrier before we get the Thule Motion XT XXL, for we cannot fully open the hatchback with the previous one because it is too long. When we receive the new Thule cargo box in our hands, we knew we had made the right decision. We were impressed we first looked at the Thule cargo box, and we liked its color, style, features, and design. When we were installing it on our vehicle, we encountered a problem with the Slidelock component. It was not fully functioning, so we contacted Thule’s customer service for solutions. After a comfortable communication, Thule’s employee solved the problem by sending us a replacement part for free. We appreciated that a lot.

How High Above the Crossbars?

Thule Motion XT L Cargo Box is a popular choice among travelers and outdoor enthusiasts as it provides ample storage space for their luggage and equipment. One of the common questions that arise when considering purchasing this cargo box is how high above the crossbars it sits.

The Thule Motion XT L Cargo Box is designed to sit at a specific height above the crossbars of your vehicle. This height ensures that there is enough clearance between the bottom of the cargo box and the roof of your vehicle, allowing for easy access to the contents of the box without any hindrance.

The exact height at which the Thule Motion XT L Cargo Box sits above the crossbars may vary depending on the make and model of your vehicle, as well as the type of crossbars you have installed. However, on average, the cargo box sits approximately 15-17 inches above the crossbars.

This height is carefully determined to strike a balance between providing sufficient clearance for the contents of the cargo box and maintaining a sleek and aerodynamic profile for your vehicle. The low profile design of the Thule Motion XT L Cargo Box helps reduce wind resistance, minimizing any impact on fuel efficiency and noise levels during travel.

It’s important to note that before installation, you should consult the user manual provided by Thule for specific instructions and recommendations for your particular vehicle. This will ensure proper installation and help maximize the performance and functionality of the cargo box.

In conclusion, the Thule Motion XT L Cargo Box sits at an average height of 15-17 inches above the crossbars of your vehicle.

Drive with a car rooftop box on the freeways

2023 April 1st Update:

A rooftop cargo box can increase your car’s storage loading capacity, but most aerodynamic roof boxes won’t affect your car’s mileage for extra costs on gas bills. The Thule Motion XT is one of the most popular choices among outdoor enthusiasts when they need to bring more luggage or equipment on the roads.

After having compatible roof racks on your vehicle, you can use the Thule Motion XT as an added loading room for your camping equipment, road trip luggage, sporting gear, hiking equipment, and more.

When installing the Thule Motion XT roof box, you can follow these five steps:

One: If your car has a naked car roof, you should consider contacting the local auto dealer to buy compatible crossbars or find one online. If you can find existing crossbars on your vehicle, you can use the Thule Motion XT without a worry because it fits on most roof racks: round, square, aerodynamic, and factory rack systems. You must accurately mount a pair of crossbars on your vehicle’s roof before adding a roof box to the rack system; otherwise, we don’t recommend those poor-quality roof racks because they are not sturdy enough to hold the job.

Two: Putting a rooftop cargo box in the appropriate position on your car roof is vital, so you should follow a guide on our site to decide where the most accurate spot is on your car roof to mount the Thule Motion XT without creating further troubles in the future.

Three: After putting the roof box in the wanted place, you can open the lid and operate four quick-mount knobs to lock it on the roof racks. During the mounting process, you need to open the box and loosen the knobs – lift the box on the roof racks – make sure the clamps stand on the roof bars – tighten the knobs – close the lid and test the results.

Four: You must perform a final test after the installation and ensure it is safe and trustable when your vehicle is in motion, even in extreme weather. You can manually shake the roof box in different directions for minutes to check if the installation is steady enough without any potential risks.

Five: Finally, you can put your stuff in the roof box and get ready for another outdoor journey. When packing things into a roof box, you should know that weight balancing is important; moreover, you should learn how to effectively load a roof box and safely drive after having a loaded roof box on your vehicle.

TIPS: Don’t drive too fast when having a rooftop cargo carrier on your vehicle because the extra weight on the car roof can change your car’s gravity center and make your driving not like usual; Consequently, you should know how fast you should drive with a loaded roof cargo carrier.

Interviewed in 2023 on Fed 26 in New York City

I ordered the Thule Motion XT on Amazon for my 2012 Toyota Sienna with factory crossbars. I did not find any interference between the roof box and the open hatchback, and I can find at least 4.5 inches distance between them when the hatchback is fully open.

Before buying the Thule Motion XT Large, I checked my Sienna’s size and decided to choose the L, which is the most suitable option in size with Sienna. I like its dual-opening feature and the advanced locking system, and I was satisfied with the purchase of the Motion XT L.

Thule Motion XT Large on Hyundai Palisade

I decided to attach the Thule Motion XT XXL to my 2021 Hyundai Palisade and haul luggage for my future family road trips. Although the Thule Motion XT is expensive, it is worth my investment. The XXL option is surprisingly big enough to hold everything I need for most outdoor adventures.

I spent 11 minutes installing the Motion XT on my Hyundai Palisade, and the glossy Motion XT perfectly matched my Palisade’s style. I tried to load four large suitcases in the Motion XT without a problem, and I tested the box through two long-way trips: 1900 miles and 800 miles; additionally, it performed well without potential problems.

Thule Motion XT roof box on Volvo S90

I drove my VOLVO S90 for years, and I wanted to use it to load more luggage when I take my friends to enjoy a road journey. I checked the most available roof boxes, but I decided to have the Motion XT as added storage space on top of my Volvo S90.

I didn’t notice much wind noise when my Volvo S90 was full of luggage, and the noise became noticeable if my car was empty; however, the wind noise is tiny and ignorable.

Furthermore, I noticed a 1mpg decrease in mileage, but it was acceptable with 22 cubic feet of loading storage added.

I like the Thule Motion XT, and I will use it on my future cars after the end of Volvo’s leasing contract.
