Thule Motion XT L Review

The XL version of the Motion XT is simply bigger in terms of cargo storage capacity and dimension, same goes for the XXL version.

Thule Motion XT L Roof Box Overview

Appearance and Design

The Thule Motion XT L boasts a thoughtfully sleek design that not only enhances its aesthetics but also improves aerodynamics. Its smooth and streamlined shape reduces air resistance and wind noise, making for a quieter drive. The cargo box is made of high-quality, durable materials, ensuring long-lasting use and protection from various weather conditions.

Among them are grip-friendly outer large handles that allow for more secure and comfortable handling when opening and closing the box. The rooftop box is also equipped with an integrated slide-lock system, allowing you to protect your camping gear and equipment during travel. Additionally, the Thule Motion XT L can be easily mounted and removed from your vehicle with the help of its PowerClick quick-mount system, which also ensures correct and secure fixation to your roof racks.

Thule’s Easy-Grip mounting system makes it straightforward to install and secure the roof box on top of your car without additional tools. The system also features dual side opening, making it easier to load and unload from both sides of the vehicle.

The Thule Motion XT L is made from high-quality materials, ensuring its durability. The sturdy construction of the box enhances its resistance to daily wear and tear, making it an ideal choice for extended use. The outer shell is made from ABS plastic, granting it both strength and rigidity. This, in turn, enables the roof box to withstand the impact of road debris or other external elements.

The roof box is also designed to provide an optimal waterproof experience. The tight seal created by the lid’s overlapping design helps keep water out. Additionally, the Thule Motion XT L features a weather-resistant design that protects the contents from rain, snow, and other adverse weather conditions.

The quality of this roof box is further demonstrated through the dual-side opening mechanisms.

The combination of quality materials, secure locking, and weather-resistant design ensures that this roof box can stand up to the challenges of long-term usage while keeping its contents safe and protected.

Handling and Gas Mileage

The Thule Motion XT L is designed with aerodynamics and ease of handling in mind. The streamlined shape of the cargo box reduces wind resistance, making it smoother to drive at high speeds. This aerodynamic design translates to less wind noise, providing a more comfortable driving experience.

Moreover, the reduced wind resistance means that the vehicle’s gas mileage is less negatively impacted than with other bulkier roof boxes. While there will always be some impact on gas mileage when using a roof box, the Thule Motion XT L manages to minimize this effect, making it a more efficient choice for road trips and outdoor adventures.

In terms of handling, the roof box is easy to install and remove thanks to its user-friendly design. The Thule Motion XT L features the PowerClick quick-mount system, which utilizes a simple and secure clamping mechanism. This allows for tool-free installation and adjustments, making it convenient for users of varying levels of experience.

It is important to note that the handling and gas mileage effects of the Thule Motion XT L will vary depending on the specific vehicle it is being used with, as well as other factors such as speed, weather conditions, and driving style. However, the Thule Motion XT L stands out as a reliable and efficient option for those seeking a roof box with minimal impact on their vehicle’s handling and gas mileage.

Dual-Side Opening Functions

The Thule Motion XT L comes with an impressive dual-side opening function. This feature enhances its user-friendly nature as it allows access to the cargo from both the driver’s and passenger’s sides. With this easy to open capability, users can efficiently load and unload items from the roof box, making it a practical and convenient solution for carrying additional luggage.

The dual-side opening not only adds to the convenience but also promotes safety by ensuring easy access to the trunk, even when the roof box is fully packed. By allowing trunk access, users can quickly retrieve essential items without having to unload the entire cargo.

The opening functions are facilitated by an easy-to-use grip-friendly handle, which ensures a secure and smooth closing and opening experience. Furthermore, the roof box comes with integrated torque indicator dials, informing users when the box is correctly mounted on the crossbars, thus eliminating guesswork and providing peace of mind.

This well-designed Thule Motion XT L, with its dual-side opening functions, aims to provide a hassle-free and secure way of carrying extra items on road trips. The innovative features make it a reliable and efficient choice for families and adventurers in need of extra storage.

Roof Box Storage and Space Efficiency

The Thule Motion XT L offers generous storage space and excellent efficiency for organizing and securing cargo. Designed with user convenience in mind, it boasts a roomy interior that can easily accommodate various types of luggage, sports equipment, and other travel essentials.

One of the key features of this roof box is its optimized space efficiency. The sleek design not only enhances the vehicle’s aerodynamics but also maximizes cargo space within the box. While the dimensions are substantial, it still provides room to spare for other gear like skis and snowboards on the roof of the vehicle.

The Motion XT L is fitted with an integrated interior light, allowing for effortless loading and unloading of items, even in low-light conditions. This thoughtful addition contributes to the overall ease of use, as users won’t have to fumble in the dark when accessing their belongings.

In terms of storage capacity, the Thule Motion XT L can hold a considerable amount of cargo. It is essential, however, to evenly distribute weight and secure items using straps or bungee cords to prevent shifting during travel. Adhering to these guidelines ensures a safer and more enjoyable journey, without worrying about any damage to your possessions or vehicle.

In conclusion, the Thule Motion XT L excels when it comes to storage and space efficiency. With its impressive storage capacity, sleek design, and practical features like the integrated interior light, it is a top choice for those seeking a reliable and well-designed roof box for their travels.

Final Thoughts

Installation is straightforward, thanks to the PowerClick mounting system, which also guarantees a secure fit to the vehicle’s roof bars. The central locking system ensures the safety and security of the cargo, while the practical carrying capacity of up to 165 pounds and 16 cubic feet of cargo space speaks to its utility.

To sum up, the Thule Motion XT Cargo Box is a durable and functional accessory for those who need additional storage while traveling.
