All of the above?
Hey bzhang, welcome to our world.
The answer to your inquiry could be any number of factors. As far as I know, there's no difference in the suspension set-up between the base and touring models. There is a difference in the tires however, but I'm not sure how much the feel of the suspension is affected by either type of tire. More importantly, tire pressure plays a huge role in how the ride feels; it's a safe bet that the vehicle that just came "off the truck" had a higher tire pressure (rumor has it they're shipped from the factory that way to help with stability during delivery). Also, the suspension of the 'X (or any new car) will soften up and become more supple as it breaks in, something I've noticed in the 2000 miles since I first drove mine.
