I'm quite surprised how well the double shoulderline is received in here. Sculptured surfaces are a weak spot of mine, and the G30 is imo an innovative example of what sophisticated surfaces can do. However, I'm still a little disappointed. Obviously, I knew an earlier approach that did not make it into production. See the pics to get my point: in these sketches, the point where the surface changes from concave to convex is somewhere in the backdoor (i.e. at the edge between front- and backdoor, it's still concave). In the series production car, the twist is located somewhere in the frontdoor (which under some lighting conditions gives the silhouette a slightly "wrung-out" feel). Probably, the solution in the sketches made broad rear wheelarches too difficult or too vulgar, or it was just too difficult to produce ... but I might have found that the more elegant solution.
Very generally, I find the 5er very different from its predecessor and from the G11. Kidneys, headlights, surfaces, silhouette, boot all introduce crucially new elements and are bot just shrunked one class ... what else could be expected?
