Both have front wishbone suspension. The Sport package adds a "sport" button on the shifter console (electrinic dampening)that when engaged firms up the suspension. I believe it function is more to do with lateral stability/body roll in cornering than plush ride versus stiffness since the standard suspension is still quite firm. At least this is my experience. Also anthracite headliner (charcoal black), three spoke leather steering wheel, shadow line trim and 19" alloys.
