Thule Motion 3 Review: Testing the New Gold Standard for Rooftop Cargo Boxes

We’ve all been there: the car is packed to the roofline, the kids are squeezed between duffel bags, and you’re still staring at a mountain of gear on your driveway that somehow needs to come along. For years, the solution was simply to bolt a plastic "bucket" to your roof and hope for the best. But as vehicles have become more advanced especially with the rise of range-conscious EVs and sleek, modern SUVs, the traditional clunky cargo box just doesn't cut it anymore.

Thule’s latest flagship, the Thule Motion 3, is the newest iteration of their most popular line. It isn't just a minor face-lift; it’s a ground-up redesign aimed at solving the two biggest headaches of roof mounted gear: air drag and ease of use. If you’re a modern adventurer trying to discover the perfect blend of space efficiency and style, this review breaks down exactly how the Motion 3 line handles the real world.

 

Watch Blake’s Take on Thule Motion 3

 

 

1. Design and Performance: The Aerodynamic Edge

The most striking feature of the Thule Motion 3 is its aerodynamic silhouette with robust functionality. Thule has moved toward a wing-shaped profile with a forward-leaning nose designed specifically to cut through wind resistance.

• Fuel and Range Efficiency: Aerodynamics aren't just for show. By minimizing wind resistance, the Thule Motion 3 ensures more fuel-efficient travels, which is a major win for both gas-powered vehicles and range conscious EV owners.
• Hatch Clearance: Thule has mastered the "forward position" on the vehicle roof. This ensures you get full trunk access with minimal risk of contact with the cargo box.
• Aesthetics: With clean lines and contemporary high-gloss finishes, this is a stylish and spacious roof box that complements your vehicle’s appearance rather than looking like an awkward afterthought.

 

2. Size Guide: Navigating the Wider Range of Sizes

Thule now offers a wider range of sizes than ever before, including specialized profile options that didn't exist in previous generations.

• The Standard Workhorses (L, XL, XXL): The Motion 3 L comes in at 16 cubic feet, while the XL and XXL offer 18 and 21 cubic feet respectively. These are designed for those who need a lid without compromising on storage capacity for massive family hauls.
• The "Low" Profile Revolution: A standout in the new line is the XL Low and XXL Low. Formerly known as "Alpine" boxes, these sit lower on the roof rack ideal for a skiing adventure where you need length for your boards but want to keep the overall height manageable for parking garages.

 

3. Comparison Table: Thule Motion 3 vs. Force XT vs. Motion XT

Choosing the right box in Thule's lineup often comes down to balancing price against features like one-handed operation and finish.

 

 

4. Practical Functionality: Experience Hassle-Free Exploration

Thule has modernized the operation of the Motion 3 to make it easier to use with one hand, which is a lifesaver when you're loading gear in the wind or rain.

• SlideLock System: The lid features separate locking and opening functions. Once you close it, the lid automatically locks in place.
• The Red Indicator: A built-in red indicator button tells you if the box is securely closed. If you can see red, the box is unlatched; once it clicks into place, the red disappears, and only then can you remove your key.
• PowerClick Mounting: The box is easy to mount thanks to the PowerClick quick-mount system. The integrated torque indicator "clicks" when it’s properly mounted, ensuring a fast and secure fitting without any tools.

 

5. Elevating the Adventure: Innovative Accessories

To truly customize your experience, the Motion 3 line is complemented by a range of innovative accessories.

• Thule GoPacks: These are color-coded duffel bags designed specifically to fit the contours of the box, ensuring you maximize every inch of space. They even include backpack straps for easy carrying from the car to the tent.
• Interior Box Light: A motion-sensing LED light that illuminates the inside of the box, making it easy to find gear during those late-night arrivals.
• Protective Box Liner: A felt liner that protects the bottom of your box and prevents your expensive skis or camping gear from sliding around during transit.
• Thule Lid Pull Straps: These make it significantly easier to reach and close the lid on taller SUVs without needing to stand on the tires.

 

 

6. Some Frequently Asked Questions from our Customers: Getting the Most from Your Gear

Is the Thule Motion 3 really "waterproof"?
No rooftop box is not waterproof because they require ventilation to prevent mold. However, the Motion 3 is highly weather-resistant. In extreme storms, a small amount of moisture can occasionally find its way in through the hinges or seals, so we always recommend using dry bags or plastic bins for electronics and expensive clothing.

Can I take the Motion 3 through an automatic car wash?
Absolutely not. You should never take a rooftop cargo carrier through an automatic car wash with spinning brushes. Those brushes can hook into the box or your roof rack and cause massive damage to both the carrier and your vehicle’s roof. Stick to "touchless" spray washes or a classic hand wash.

Will it interfere with my vehicle's sunroof?
In 95% of cases, the PowerClick mounts provide enough height to allow your sunroof to tilt or vent. However, on some vehicles with large panoramic glass roofs, the sliding glass may sit higher than the mounts. We always recommend doing a careful "test tilt" the first time you install the box.

How do I maintain the high-gloss finish?
To keep that "black glossy" shine, use a mild automotive soap and a microfiber cloth. Avoid abrasive cleaners or stiff brushes that can swirl or scratch the finish.

 

Final Verdict: Is it Worth It?

The Thule Motion 3 is designed for modern adventurers who want a roof box that combines style with high-performance aerodynamics. While it sits at a premium price point, the enhanced functionality, SlideLock safety features, and fuel-efficient profile make it a long-term investment that pays dividends every time you hit the highway.
