Just checked the pics of the 2012 motorshow DS4R concept car and that was similarly spaced, not touching like the DS3R as you can see below. Probably because it can't appear out from behind the lower case 4 font like it can the 3
So they've been added in leu of the factory black and chrome door strips ?
I gather that some of the DS4's in UK were supplied without the door mouldings.
The rear one is surely just to balance the "look" because the spearhead door handle would hit a wall or object well before the actual door, right !
It does look balanced. What is their profile, shape ?
