I've never driven in the sand, but based on cleaning the front bumper a few times, I would think anything you strongly hit would break the bottom part of the front bumper. It seems to be more cosmetic than anything else.
Yes, this is NOT an off-road vehicle, but more an all-weather road tourer.
As said, very hard packed sand should be no problem...but anything beyond that, it may be able to do it, but it wouldn't be recommended. Between the bumpers and the AWD/suspension set-up for smooth road use, jumping sand dunes (or just running around them at any speed) probably would not be advised or possible.
