Don't know for sure and it would be very difficult to find out, and piccies would'nt help as probably on the ouside it would look the same, but usually what European manufacturers do for the American market is soften up the suspension as you guys like a softer ride than us Europeans.
Your roads are straighter and smoother, so a nice comfy ride is preferred, whereas in Europe handling is more of an issue, so the suspension is stiffer.
I have had a Jeep Cherokee and the car was beautifully smooth to drive, lovely and floaty and you did'nt feel the bumps, but the handling was awful, did'nt do corners, and I have driven a Chevy Impala 2,500 miles, doing a tour of the Canadian Rockies and that was an awesome tourer, you could drive 10 hours in a day and get out as fresh as a daisy.
smarts in this country have a reputation of being stiff and crashy over bumps, but they handle fairly well.
Hope this helps.
