2016~2021 CX-9 Roof box: Thule Motion XT XL

Just picked up a Thule Motion XT XL.

I was not 100% about the size (large versus extra large); the guy at REI convinced me to go with the XL and I'm glad I did (perfect fit).

Box is mounted via Thule Evo Wingbar cross bars.

Looking forward to getting luggage and sports equipment out of the cabin.

Just drove 1,000 miles with the Thule Motion XT XL. There's a slight wind noise but it's hardly noticeable. And no noticeable change in MPG (hard to believe).

Also worth mentioning, I still fit in parking garages. The height limit is often 7'2 and I'm at 7'0...

@roundle1979 Hi there, can you please let me know the Thule part numbers you have used for this? And do you have factory fitted flush rails?

What kind of MPG numbers are you getting before and after? I'm very concerned with the MPG hit. I would think it would be more noticeable at higher speeds.

Are the cross bars and roof box easy to remove when not in use?
 
I drove 2800 miles from NY to CA without the box, then 2800 miles from CA to NY with the box. I did not notice a difference in MPG, shockingly.

I leave the cross bars on year round. The box is very easy to take off with two people. I will leave the box on for the ski season and in the warmer months only use it for road trips.
 
I was undecided between a Thule motion L or XL. My main concern was with the rear antenna since I have the OEM roof rack and it seems to sit lower then the aftermarket bars. I took the plunge after seeing this post and I am glad to report that the XL fits just as well with the OEM rack. There is still about 2 inches left above the antenna, and lots of room to move the box forward or backward as preferred. Photos are from my fit test (plastic wrapper still on the box). With the box as far as I would be confortable having it without interfering with the liftgate.

Well done.

We've done a lot of miles with our roof box. For a family of 5 who typically use all three rows on longer trips, the box is a game changer. I also left the skis (about 5 pairs) in the box all winter...

I notice that the box does negatively influence XM reception a bit but it does not kill it all together.
