Your 328d is identical in terms of output and build to 'our' 320d. The 325d is substantially uprated, in comparison. Larger oil cooler, a twin-turbo unit (the 328d/320d is a 'twinpower' single turbo unit), uprated oil pump, different exhaust.
I think the US cars will also tend to be more reliable on timing chains because you've got a far shorter oil-change interval. Here the 'official' interval is usually 18-20k miles. Which is great for the fleet market that runs a car for 3 yrs/60k, but terrible a further 3-5 years down the line.
