and coming back to the ocean drive and CS
well the concept here is radically different, MB has already introduced us with the design langauge it will be using the coming decade
it is the S class design reinterpreted for various models
big, brash, in some ways vulgar, not always cohesive, but perfectly conveying the classical MB cliche of "the paycheck in my mont blanc wallet is 10 times as big as yours" more so than ever even.
the OD concept, is a reinterpretation of the S class design, refined where it was at lacks and with added value of a "radical" age old idea of chopping the roof off a 4 door.
it might eb a purported range topping flagship, but it sits perfectly within the currently established MB tradition

as for the CS, well it is a whole different can of worms here
the CS as opposed to the OD and audi, is introducing a new design language primarily, by showing us cues from eveyr major upcoming BMW model (7er, X6, F5 etc....) and also ushering in the diea of a range topping sleek sporting panamera and rapide competitor that will bridge the gap with RR (knwoing bangle i am inclined to think that the seraphe will share some fleeting cues with this also to render everything full circle whilst loosing none of the RR genes BMW have established so well)
the CS design is unto itself an adventure, a showcase of bold ideas and lines that have not been attempted before on mainstream vehicles, (the 2 hump roof, the sleek roofline, the butt etc...) this takes the idea of the bagle butt to another level, it\s not just about reinterpretting an idea, or revolutionizing it, we are looking into introducing whole enw concepts, like the side skirts and the very interesting concave convex progressions above the wheel arches
don't take the BMW as a whole, although it is a great case unto itself, see it as its parts, every design elemnt, which will progress into perfection and cohesion in the hands of a lebanese guy, or syrian woman, in their respective model designs

and here lies the fundamental difference between all 3 concepts
