10 Best Car Top Carriers 2025 in the United States

The Thule Motion 3 XXL is a large rooftop cargo box offering 21 cubic feet of storage, ideal for families or anyone needing extra space for trips. It can hold up to 165 pounds, supporting a substantial load for gear or luggage. Made from durable aluminum, it’s sturdy but relatively heavy at 35 kilograms.

Its wing-shaped, aerodynamic design helps reduce wind drag, potentially improving fuel efficiency compared to bulkier boxes. The box mounts easily with the PowerClick quick-mount system, which clicks to confirm secure installation—this tool-free setup is user-friendly, especially for those new to roof boxes. Opening and closing is smooth and can be done with one hand thanks to the wide handle. Security is enhanced with the SlideLock system, which automatically locks the lid and shows when it’s secured, helping keep belongings safe.

However, it is not water resistant, so it is advisable to avoid heavy rain or snow conditions or consider additional protective liners (available as accessories). Its large size means it might not fit all car roofs or low-clearance garages comfortably. This cargo box is suitable for users who prioritize easy mounting, good security, aerodynamic design, and plenty of capacity, while considering its weight and lack of water resistance when planning trips.

The Thule 614 Pulse Rack is designed for those looking to expand their vehicle's cargo space, particularly useful for families, outdoor enthusiasts, or anyone needing extra storage for road trips. With a capacity of 14 cubic feet and a load capacity of 110 lbs, it strikes a good balance between ample space for gear and maintaining a manageable weight on your car's rooftop. The external dimensions of 67 x 35 x 16 inches make it spacious yet compact enough to fit most vehicles.

One of the standout features is the FastGrip quick-mount system, which allows for easy assembly and installation in minutes, making it user-friendly for those who may not be experienced with mounting systems. The passenger-side opening is a thoughtful design for convenient loading and unloading. Additionally, the central locking system enhances security, ensuring your belongings are safe while you’re on the go.

While the Thule 614 Pulse Rack offers many advantages, there are some considerations to keep in mind. The product is made from plastic, which, while providing durability, may not be as resilient as other materials like fiberglass in extreme conditions. Also, with a height clearance of 16 inches off the crossbar, it might slightly affect your vehicle's aerodynamics, potentially leading to increased wind resistance and fuel consumption.

Lastly, though the carrier is designed to fit 3-5 snowboards, users may find that it has limitations if they need to transport larger items or multiple bags—it's essential to consider what you plan to carry. Despite these drawbacks, the Thule 614 Pulse Rack remains a popular choice for its capacity, security features, and ease of use, making it a solid investment for those needing extra roof storage.

The Thule Motion 3 LTitan is designed for users looking for a reliable and efficient car-top carrier. One of its standout features is its aerodynamic wing-shaped profile, which reduces drag and contributes to better fuel efficiency—ideal for long trips. The sturdy lid design allows for easy one-handed operation, making loading and unloading a breeze. The PowerClick quick-mount system ensures a secure fit, with an audible ‘click’ that signals when it's properly attached, a comforting feature for those who may be new to mounting roof boxes.

In terms of capacity, this large carrier offers ample storage with a volume of 450 liters, suitable for families or anyone needing extra space for gear. It’s made from durable aluminum, promising longevity and good water resistance to protect your belongings from the elements.

On the downside, the weight capacity at 24.04 kilograms might limit how much you can pack, especially if you have bulky items. Some users might find the size a bit cumbersome, making it challenging to handle without assistance when not mounted on the vehicle. Additionally, while the SlideLock system provides added security, it’s crucial to ensure that the lid is locked correctly, as mishaps can occur if not checked. This product suits families and outdoor enthusiasts needing extra space for their adventures, balancing performance with user-friendly features.
