Why Choose the Motion 3?

The Motion 3 combines generous storage capacity with premium design and refined everyday operation. Its contemporary shape is designed to complement your vehicle while providing convenient access to equipment throughout the year.

Compared with a more utility-focused cargo box, the Motion 3 emphasizes aerodynamics, one-handed operation, glossy styling and compatibility with premium accessories such as fitted liners, interior lighting and storage covers.

Why Choose the XL Size?

The Motion 3 XL is designed for travelers who need more space for family trips, outdoor adventures and winter equipment. Its 18-cubic-foot interior provides additional room for luggage and bulky equipment without moving to the largest Motion 3 size.

The extended 84.7-inch length can accommodate skis up to 200 cm, while the 35-inch width provides generous room for luggage and general cargo. Always confirm available roof space, crossbar positioning and rear-hatch clearance before ordering.

Generous Capacity for Every Season

The Motion 3 XL can accommodate up to 5–7 pairs of skis or 3–5 snowboards. Outside of winter, its spacious interior is ideal for suitcases, duffel bags, tents, sleeping bags, strollers and other bulky travel equipment.

The cargo box has a maximum load capacity of 165 lbs. Your actual allowable cargo weight is determined by the lowest-rated component in the system, including the vehicle roof, crossbars, mounting system and cargo box.

Designed with Aerodynamics in Mind

The Motion 3’s wing-shaped profile and dynamic, forward-leaning nose are designed to reduce aerodynamic drag. Its streamlined silhouette provides a clean fit on modern vehicles while helping limit unnecessary wind resistance during travel.

Smooth One-Handed Operation

A sturdy lid and wide ergonomic handle provide controlled one-handed opening and closing, even when the cargo box is wet or dirty. DualSide opening lets you access your equipment from either the driver or passenger side of the vehicle.

This flexibility is especially helpful in garages, parking lots and campsites where access may be limited on one side.

PowerClick Mounting and SlideLock Security

Thule’s PowerClick quick-mount system makes installation straightforward and intuitive. The tool-free mounting hardware tightens around compatible crossbars, and an integrated torque indicator clicks when each mounting point has been tightened correctly.

The SlideLock system separates the opening and locking functions. It automatically locks the lid and indicates when the box has been closed correctly, helping ensure your equipment is secure before you drive away.

Enhance Your Motion 3

Customize the Motion 3 XL with available accessories designed to make packing, loading and storage more convenient.

• Custom-fit box liner helps protect the interior and your cargo.
• Interior box light improves visibility when loading after dark.
• Protective lid cover helps keep the cargo box clean while stored.
• Thule GoPack duffel set makes efficient use of the available interior space.
• Ski carrier adapter helps organize winter equipment inside the box.

Roof Rack Compatibility

The Motion 3 XL installs directly on several Thule crossbar systems. Some truck, van and platform-rack applications require an adapter.
