What's the difference between X1's that have the long silver bar with ridges at the bottom (chin) of the front bumper cover and those that have the short smooth silver bar (with black on either side)? Based on the BMW Configurator, It appears that all 2015 X1 models (unless Sport Line or M Sport) have the long silver bar, regardless of engine or sDrive or xDrive. But I see X1's (presumably older ones?) with the shorter silver chin bar.
