Thule's Sonic XL Rooftop Box significantly increases the carrying capacity of any vehicle, and with the AeroNose design it reduces drag and wind noise. The angled rear section of the box increases trunk or hatch clearance. For added convenience, the Sonic opens from either side. Thule makes it easy to make sure the box is closed securely and properly with the Sonic's oversize SecureLock latch. This great rooftop box also includes AcuTight mounting hardware that clicks when tight and fits on Thule crossbars (sold separately), plus most after-market and factory-installed racks.
If you drive a van or SUV for its carrying capacity, but find the expenses of driving it a bit excessive, you might be interested to learn that you could instead drive a sportier and smaller car with a rooftop box. In most cases this setup exceeds the carrying capacity of your SUV and gets significantly improved mileage, too. Plus, rooftop boxes provide easy access, easily fit on all vehicles and can be quickly removed when they're not needed.
Capacity: 17 cubic feet
